UC Davis Offering Beginner Beekeeping Classes

Do You Want to Become a Beekeeper or Learn More About Beekeeping?

News Release

The California Master Beekeeper Program (CAMBP), directed by Extension apiculturist Elina Lastro Niño of the UC Davis Department of Entomology and Nematology, is hosting two short beekeeping classes in early August: one on “Planning Ahead for Your First Hives” and the other, “Working Your Colonies.”

Each will take place from 9 a.m. to 4 p.m. in the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, west of the central campus. The deadline to register is Thursday, Aug. 1.

“These courses are foundational to beekeeping husband excellence,” said Wendy Mather, program manager. “They are great for folks who are thinking about getting bees next season, as well as those who currently have bees and want to ensure they’re doing whatever they can to ensure the success of their hives.”

The classes are not required to become a California Master Beekeeper, but are highly recommended, as “they will help folks prepare to become a science-based beekeeping ambassador,” Mather said. Instructors are Elina Niño and CAMPB educational supervisor Bernardo Niño, a staff research assistant in the Niño lab.

Planning Ahead for Your First Hives
“Planning Ahead for Your First Hives” will take place Saturday, Aug. 3, and will include both lectures and hands-on activities. Participants will learn what’s necessary to get the colony started and keep it healthy and thriving. They will learn about bee biology, beekeeping equipment, how to install honey bee packages, how to monitor their colonies (that includes inspecting and monitoring for varroa mites) and other challenges with maintaining a healthy colony.

The course is limited to 25 participants. The $105 registration fee covers the cost of course materials (including a hive tool), lunch, and refreshments. Participants can bring their bee suit or veil if they have one, or protective gear can be provided. For more information or to register, see https://registration.ucdavis.edu/Item/Details/572.

 Working Your Colonies
“Working Your Colonies” will take place Sunday, Aug. 4, and will include both lectures and hands-on activities. Participants will learn what is necessary to maintain a healthy colony. Lectures will cover advanced honey bee biology, honey bee integrated pest management, and products of the hive. Participants also will learn about queen wrangling, honey extraction, splitting/combined colonies, and monitoring for varroa mites.

The course is limited to 25 participants per session. The $175 registration fee covers the cost of course materials, lunch, and refreshments. For more information or to register, see https://registration.ucdavis.edu/Item/Details/559.

Participants can bring their bee suit or veil if they have one, or protective gear can be provided. All participants are to wear closed-toed and closed-heel shoes, long pants and a long-sleeved shirt.

The California Master Beekeeping Program uses science-based information to educate stewards and ambassadors for honey bees and beekeeping. For more information, contact Mather at wmather@ucdavis.edu.

Even Organic Production of Strawberries Not Sustainable

Data Shows Even Organic Production Uses Resources

By Jessica Theisman, Associate Editor

Is growing strawberries organically sustainable? That’s something that Surendra Dara is trying to find out. Dara is a UC Cooperative Extension Advisor in Entomology and Biologicals. He is based in San Luis Obispo County as well as Santa Barbara County. Dara met with California Ag Today recently and let us in on his research and some of his findings.

“I have not come across a mainstream grower that has told me that organic is sustainable,” Dara said.

After pulling in data and understanding the inputs, Dara is asking if there is anybody out there that has a different opinion.

“When we are talking about sustainability, we are looking only in terms of non-chemical being the sustainable, ecological practice,” he said.

There are such things as organic pesticides that harm natural enemies.

“Some of the organic ones can be as bad as some of the chemicals,” Dara said.

Data is showing that growing strawberries organically has not been sustainable economically. In terms of the carbon footprint and the bigger picture, “even organic production is not sustainable with the resources because certainly some resources are being used up,” Dara said.

Commentary on Water Issues from Families Protecting The Valley

Unintended Consequences

By Families Protecting The Valley

As Californians endured the drought, they did an excellent job conserving water—maybe too good.  As the article below from Families Protecting The Valley explains, all the low flow toilets, all the 1-minute showers meant less water pushing waste through the sewers.  All that “resulted in corroded wastewater pipes and damaged equipment, and left sewage stagnating and neighborhoods stinking. Less wastewater, and thus more concentrated waste, also means higher costs to treat the sewage and less recycled water for such things as irrigating parks, replenishing groundwater or discharging treated flows to rivers to keep them vibrant for fish and wildlife.”

So now some water agencies are pushing for more outdoor conservation efforts rather than indoor to keep the wastewater flowing.  Adam Link, director of operations with the California Association of Sanitation Agencies asks the key question:  “At what point are you causing more harm than the benefit you are getting from saving those drops of water?”

Another major point we would point out is with the reduced VOLUME of water flows, it has created higher concentrations of pollutants per each gallon of water that gets discharged into the Bay-Delta. With low flow toilets’ rates at 1/2 or lower previous volumes and appliances using less water, all the pollutants that impact fish and people are at double or more on a per-gallon basis getting dumped into the Bay-Delta. Some permit to dump 180 million gallons of sewage water into the Bay-Delta, but the pollutant concentration is double or more.  This makes the pollution from sewage plants going to the delta that much more troubling.

Remember, in 2010, water authorities determined the Sacramento Regional Wastewater Treatment Plant “was discharging too many pollutants into the Sacramento River, threatening public health and harming aquatic life in the Sacrament-San Joaquin Delta.”  The water board found that high volumes of ammonia in the water were disrupting the food chain and endangering fish such as salmon and Delta smelt. Single-celled organisms posed health risks to people who came in contact with the river water.

Wastewater authorities were given until 2021 to remove the ammonia, giardia, and cryptosporidium which endanger fish and humans.  In the meantime, the pollutants keep coming and the policy of cutting off water for farmers is still the favored solution.

This is why farmers are so frustrated.  They see the wastewater situation as the real threat to endangered fish, but water the bureaucrats sole solution to Delta health problems is withholding water from farmers.

North American Climate Smart Agriculture Alliance Looks for Solutions

Solutions From The Land on System Implementation

By Jessica Theisman, Associate Editor

California Ag Today recently spoke with Ernie Shea, president of Solutions From the Land. He explained the importance of system implementation and the North American Climate-Smart Agriculture Alliance.

“Our primary areas of focus at the moment are clean energy, climate change, and soil and water conservation in the 21st century,” he said.

They are integrating these areas of focus and the systems involved. There is still a need to find a solution for profitability.

“The biggest and important areas of focus is finding a way to respond to the changing climatic conditions and deliver solutions that create wealth and job opportunities for agriculture,” Shea said.

North American Climate Smart Agriculture Alliance is looking for ways to deliver solutions.

“We have created the North American Climate Smart Agriculture Alliance, and it is the continental platform for farm and conservation groups that are looking at ways these landscapes can deliver solutions,” Shea explained.

There are conversations taking place at the state level about becoming more sustainable, resilient, and participating in the low carbon economy.

“Carbon sequestration is one of the more exciting new areas of opportunity that are coming for agriculture,” Shea said.

Farming has been framed as a problem in the past.

“Oftentimes, we’re framed as the problem child,” Shea said.

When managing a farming operation, good solid conservation practices are important.

“No-till cover crops are an example that you are increasing the organic content. You are sequestering carbon at a scale that goes beyond what people originally gave us credit for it,” Shea explained.

Well-managed agricultural systems help on many levels. In the upper Midwest, there are continuous corn operations, even no-till corn operations.

“They were measuring the carbon content in the first meter, and they weren’t realizing that the root systems, we’re pulling carbon down well below one meter down to two meters in deeper,” Shea said.

These monoculture landscapes are labeled as something bad. This landscape, in particular, was a critically needed solution. Well-managed agricultural systems can deliver food, feed, fiber, energy, and environmental services.

“If we can figure out a way to create a monitoring and measuring system, then 21st-century agriculture will be seen as solutions, not defined as problems,” Shea said.

Delta Smelt Are Poor Swimmers, Unlikely to Reach Pumps

How Many Smelt Are Actually At the Pumps?

By Kristi Diener, Fourth Generation San Joaquin Valley Farmer

Delta smelt are poor swimmers. When they have to swim against voluminous outflows, they struggle. They also lack endurance for distance and swimming against currents. This was the result of the taxpayer-funded swim performance test conducted more than 20 years ago. Why is this important?

Delta smelt live in the freshwater/saltwater mixing zone made up of outflow from the fresh waters of the Sacramento and San Joaquin Rivers, and the inflow of saltwater pushed towards that freshwater from the ocean tides. Smelt leave this mixing zone in search of freshwater to spawn, in the late winter to early spring. It is the same time of year when the outflows from the Sacramento and San Joaquin Rivers are at their peak. Recently, water surging out from the rivers was equal to 104,900 basketballs per second!

If the smelt are able to swim against these powerful outflows, they don’t go too far, and generally spawn pretty close to the nearest region of freshwater they can find in the delta. However, most smelt being surveyed during spawning are not in the delta at all, rather, in the much smaller waterways to the north where there is a fraction of the freshwater outflow. Twenty-one years ago, UC Davis acknowledged outflows from the Sacramento and San Joaquin rivers are actually too high for the endangered smelt!

Let’s jump to the “pumps.” They are about 60 miles away from where smelt live in the mixing zone of the Suisun and San Pablo Bays. The pumps capture water at the south end of the delta, where it later flows into storage at San Luis Reservoir. Eventually, it is conveyed south to 2/3 of the state.

Water that is not captured by pumping surges out from the Sacramento and San Joaquin Rivers into that mixing zone. These pumps are routinely throttled back because, according to the Smelt Biological Opinion, smelt are in danger of getting sucked-in and killed. The result of not pumping is huge losses of water for human use and huge increases of outflow from these two rivers into the ocean.

So how many smelt, who lack endurance for long swims according to the swim performance test, are actually surveyed near the pumps and at risk of being liquidated? Every month, a trawl survey is conducted to count smelt and find out where they’re hanging out. I pulled up the fish distribution maps for every monthly trawl over a 10-year period. The closest a smelt has been surveyed near the pumps is about 30 miles away from them, seven years ago.

Still, in spite of their own swim performance tests, the opinion is that smelt swim about a 60 mile, squiggly endurance course, destined for the pumps. Remember, they spawn in freshwater, but actually, live back in the mixing zone where they must return. Nonetheless, this opinion is the very hypothesis that ratchets back pumping at full capacity and prevents the securing of water for humans. There are many other facets of the opinion that are questionable as well. Incidentally, just two smelt have been surveyed anywhere in the last 10 months.

Here’s the good news. President Trump signed an executive memo in October, requiring the Biological Opinions to be reviewed and updated. The science is well over a decade old. Please notice it is called an “opinion”, not a fact. Trump set a timeline and a deadline to get it done too. The assessment phase had to be completed by January 31, and it was. The deadline for the new Opinions to be issued is 135 days after the assessment, which I calculate to be around June 15th. I’m counting.

In the next couple of months, we’ll likely be hearing a whole bunch of malarkey coming from the folks favoring water for the sea in the name of fish, instead of for humans and the earth. There will be an uproar when the Biological Opinions are revised to actually help endangered fish, instead of being used as a vehicle to implement an agenda of man-made water shortages, more regulations, increased fees, and new taxes. You will hear misinformation, but you will know the truth.

Don’t Be Fooled, High Heat Will Return

Farm Employees Must Be Protected During High Temps

By Patrick Cavanaugh, Editor

The cool and rainy weather will eventually turn to higher temperature days, and when high heat returns to the Central Valley, it’s essential that farm employees are getting enough water, rest, and shade. Manuel Cunha, the President of the Nisei Farmers League in Fresno told California Ag Today that during hot days, we’ve got to protect employees.

“Training is the first important step to prevent heat illness,” Cunha said. “All employees and supervisors must know about heat illness prevention.”

Water is the next important step in preventing heat stress.

“Employers or supervisors must provide enough fresh water so that each employee can drink at least one quart per hour—or four 8 ounces glasses per hour—and encourage them to do so,” Cunha said.

Manuel Cunha, President of the Nisei Farmers League, Fresno

Shade is the next critical step to prevent heat illness.

“Employees should have access to shade, and they should be encouraged to take a cool-down rest in the shade for at least 5 minutes,” Cunha explained. “And employees should not wait until they feel sick to cool down.”

Finally, all ag employers must develop and implement written procedures for complying with the Cal/OSHA Heat Illness Prevention Standard.

 Temperature Triggers

Shade shall be present when the temperature exceeds 80 degrees Fahrenheit. The employer must maintain one or more areas with shade at all times while employees are present that are either open to the air or provided with ventilation or cooling.

The amount of shade present shall be at least enough to accommodate the number of employees on recovery or rest periods so that they can sit in a healthy posture fully in the shade without having to be in physical contact with each other.

The amount of shade present during meal periods shall be at least enough to accommodate the number of employees on the meal period who remain onsite.

The high-heat hazard temperature is 95 degrees or higher. This is when the employees must take a ten-minute preventative cool-down rest period every two hours. Often, farm operations will cease for the day and restart in the morning.

“Farmers, supervisors, packinghouses, farm labor contractors, all of these folks should have their Heat Action Plan ready, and all employers should be aware of it,” Cunha said. “They have to be ready to go, and that crew bosses, managers, foremen are making sure that the workers are getting shade and drinking plenty of water.”

If farm operations need to change their time schedules to accommodate the high temperatures, they need to implement that, as well as making sure that the workers take their proper breaks, and they have a meal.

“Lunchtime is very important for the workers to be nourished and strong,” Cunha said.

When employees are acclimating to the higher temperatures, a buddy system is essential.

“You want to make sure somebody isn’t sweating a lot or beginning to feel nauseated. As workers, they need to be looking out for each other as well. You cannot always depend on the crew boss seeing a problem,” Cunha explained.

Emergency Contacts

In some places, cell phones don’t work, so workers may have to have a two-way radio. Make sure there is a way to call 911 during an emergency. Make sure you have maps posted to where the employees are working, and all the workers know where they’re at.

“If something goes down, they need to call 911, the worker or crew boss needs to say where they’re at—the address, the location, the cross streets,” Cunha stressed.

“The location should be posted on a clipboard to make sure that you have the information there for those employees,” Cunha continued. “That’s very important, to know the procedures.”

“We want all employees to go home safe to their families every night. So farming operations must have heat illness prevention plans in place,” Cunha said.

Farm operations should be sure that a supervisor is in place in all fieldwork and that supervisor must have first aid and CPR training. And if the supervisor leaves the crew for any reason, they must make sure someone is in charge.

First aid and CPR are vital with our farm crews working in the fields or even in the construction industry. Farm labor contractors must be sure that field supervisors are licensed for first aid and CPR.

Western Growers Statement on California DPR Ban on Chlorpyrifos

Tom Nassif: CA Farmers Face the Most Stringent Regulations in the World

By Cory Lunde, Western Growers

In response to the recent announcement that the California Department of Pesticide Residue (DPR) is acting to ban the use of the insecticide chlorpyrifos, Western Growers President and CEO Tom Nassif issued the following statement:

“California farmers are universally committed to the safety of their food, the health of their workers and communities, and the sustainability of their land. At every turn, they strive to achieve efficiencies in their use of resources like water, fertilizer, and pesticides and seek to minimize both the human and environmental impacts of these inputs.

Tom Nassif

“California farmers also face the most stringent regulatory environment in the world, one that often limits their access to many of the tools still available to farmers elsewhere in the U.S. and in foreign countries, including certain types of pesticides. Indeed, over the last 20 years, California regulatory actions have removed several of the most important crop protection tools farmers rely on to fight pests and diseases.

“With … [the] announcement that DPR will initiate the cancellation of chlorpyrifos, one of the most widely studied and globally approved insecticides, California farmers now stand to lose yet another arrow in their quiver—without effective and ready replacement tools—making their quest to grow the safest, healthiest and most abundant food supply in the world even more difficult.

“California farmers are resilient, but the long-term viability of our farms in California depends on proper support from the Administration and renewed cooperation of the state’s regulatory agencies, especially in light of the many other unique and expensive regulations that place California farmers at a growing competitive disadvantage.”

Wastewater Treatment Plant in Delta Causing Problems

Harmful Algal Blooms Impacting Watershed

News Release Edited By Patrick Cavanaugh

The San Francisco Bay Regional Water Quality Control Board updated its regulations on nutrient discharges into the San Francisco Bay watershed recently to protect the watershed from harmful effects of discharges from municipal wastewater treatment plants and other sources.

Although San Francisco Bay is not impaired by nutrients, it is a nutrient-enriched estuary with higher nitrogen and phosphorus concentrations than most estuaries in the world. Too much nitrogen and phosphorous can lead to harmful algal blooms, which can release toxins to the Bay. Harmful algal blooms can also result in low dissolved oxygen or insufficient oxygen in the water to support aquatic life.

In the Bay, nitrogen has the biggest influence on phytoplankton growth, and the Region’s municipal wastewater treatment plants account for 65 percent of the nitrogen discharged to the Bay. Regional population growth will increase these nitrogen discharges.

The regulatory update, in the form of a reissue of the Nutrients Watershed Permit first adopted in 2014, provides a consistent approach for regulating nutrient discharges from municipal wastewater treatment plants in the San Francisco Bay watershed.

The first Nutrients Watershed Permit required sewage treatment agencies to: (1) monitor their discharges, (2) support scientific studies to evaluate the Bay’s response to current and future nutrient loads, and (3) evaluate opportunities to remove nitrogen through treatment plant improvements.
This update will increase monitoring and scientific studies. Importantly, it requires treatment agencies to evaluate opportunities to remove nitrogen using “green” solutions, like routing wastewater through treatment wetlands and wastewater recycling.

These types of opportunities may provide water quality benefits beyond nutrient removal, for example, by providing protection against climate change through carbon sequestration and adaptation of the shoreline to address sea-level rise. Green solutions can also remove additional contaminants of emerging concern for water quality.

CCM Statement on Chlorpyrifos Ban

Flawed Data Forcing Cancellation

News Release From California Citrus Mutual

Recently, the California Environmental Protection Agency (CalEPA) and the California Department of Pesticide Regulation (DPR) announced that they are going to begin the cancellation process of chlorpyrifos. The statement cites scientific findings that chlorpyrifos poses serious public health and environmental risks to vulnerable communities.SaveOurCitrus Logo

“The decision to ban chlorpyrifos is not surprising given the significant pressure from anti-pesticide groups, active legislative proposals, regulatory proceedings, and ongoing court battles,” said CCM President Casey Creamer. “However, this decision relies heavily on an evaluation that was significantly flawed and based upon unrealistic modeling scenarios that are not verifiable by actual results in DPR’s own air monitoring network.”

“California Citrus Mutual and our member growers stand by science that is sound, that properly evaluates risks and puts forward appropriate safeguards to protect ourselves, our employees, and our surrounding communities. We are committed to safe and effective use of chlorpyrifos and other crop protection tools.”

“The process for which this chemical was evaluated was purposely exaggerated to achieve the desired outcome and jeopardizes the scientific credibility of the Department of Pesticide Regulation. This decision sets a terrible precedent for future evaluations and creates a chilling effect on companies planning on making significant investments to bring new products to the market in California.”

“The citrus industry is fighting feverishly to protect itself from the deadly citrus disease, Huanglongbing,” Creamer continued. “In order to do so, we must have the necessary tools in the toolbox for an effective Integrated Pest Management program.”

“The once mighty citrus-producing state of Florida has lost 70% of its production due to this disease, which is expanding exponentially in residential citrus trees in Southern California at this very moment. While our commercial growers will remain vigilant, it is vital that our policymakers recognize the seriousness of the threat and ensure sound scientific procedures are followed.”

“California Citrus Mutual will continue to be actively engaged in the regulatory processes around the cancellation decision and will continue to explore all potential remedies to allow the safe and effective use of chlorpyrifos.”
