LUNA—ANOTHER RELIABLE FUNGICIDE TOOL

Luna Fungicide Offers Great In-Season Protection with Post-Season Secondary Benefits

By Patrick Cavanaugh, Editor

Three different formulations of Luna Products are benefiting growers while offering a good rotation product for resistance management and even extending shelf life of cherries and apple.

With Luna Experience, Luna Sensation and Luna Tranquility, growers now have a systemic solution proven to control a wide range of horticultural diseases. Effective on almond, apple, cherry, pistachio, potato, tree nuts, watermelon and wine grape crops, Luna provides unprecedented control of some of the most problematic fungal diseases to help growers deliver the best possible fruits, nuts and vegetables.

“Luna is an outstanding fungicide for protecting fruit, nut crops, and vegetables from a wide range of fungal disease such brown rot, grey mold, Alternaria, and powdery mildew, shothole on almonds,” said Jim Adaskaveg, UC Riverside Professor and Pathologist.

Luna Tranquility with active ingredients Fluopyram and Pyrimethanil is in FRAC Group 7 and 9. It is registered on apples, potatoes and winegrapes.

Luna Experience with active ingredients Fluopyram and Tebuconazole is in FRAC Group 7 and 3. It is registered on almonds, pecans, pistachios, as well as other tree nuts, watermelon, and winegrapes.

Luna Sensation with active ingredients Fluopyram and Trifloxystrobin is in FRAC Group 7 and 11. It is registered on almonds, apples, cherries, watermelon and treenuts.

The active ingredient Fluopyram, which is in all the Luna formulations, is new pyramide chemistry. Fluopyram has been found to bind more tightly to the target site than other SDHI materials. The distinctly different structure and flexibility of the Luna active ingredient allows it to remain effective where other SDHI products are failing due to resistance.

“The Luna formulations are premixed with active ingredients in different FRAC groups and have been shown to be excellent in protecting various specialty crops from diseases, while providing much needed resistance management. In fact, Luna provides the broadest options for preventing and managing resistance,” said Adaskaveg.

Key Diseases include:

· Powdery Mildew

· Alternaria

· Scab

· Botrytis

· Botryosphaeria

· Bunch Rot

· Gummy Stem Blight

· Monilinia

· Shothole

· White Mold

Rob Schrick, Horticulture Business Lead for Bayer Crop Science, commented, “Every once in a while we come out with a blockbuster, herbicide, fungicide, insecticide, or biological. But we come across applications outside the original intent of the product, and Luna fungicide is one of those products.”

Luna is currently registered on seven crops throughout the U.S. including apples, cherries, tree nuts, wine grapes, potatoes and watermelons. “It’s used as a traditional regiment fungicide application. But we are seeing, as growers use this product in their current practices, that that the harvested crops exhibit high quality and extended shelf life in cherries and apples,” Schrick noted.

“In cherries, we see a dramatic difference in quality due to an in-season application of Luna,” explained Shrick. “What we are seeing in cherries, as well as apples, is up to two or three weeks of extended shelf, but the quality characteristics are also extended.”

“Our focus is the grower,” Shrick said, “and what we are trying to understand is what the value of this quality component is to the grower.”

“We are looking to expand this registration to many different crops,” Shrick commented, “which should be completed in 2015 and ready for growers for the 2016 season.”

“Science is not completely settled on this, but we believe that the postharvest benefit comes from superior control of various in-season diseases and reductions of inoculum from earlier in the season,” said Mark McAuley, Product Manager for horticultural fungicides.

“Sometimes we do not see the effect of the fungi until after harvest, but the stage is set much earlier in the year when the pathogens are on the fruit and, in some cases, even embedded into the skin of the fruit,” McAuley said. “Once in the outer skin of the fruit, they lay dormant until harvest or postharvest when conditions are more favorable for the fungi to grow. The length of fungi control postharvest is unique with Luna compared with other fungicides,” he said.

McAuley noted that testing on other pending registered fruits and vegetables is showing similar postharvest benefits.

POLICY UPDATE ON FOOD SAFETY MODERNIZATION ACT

CAFF Update on FSMA

TODAY, Dave Runsten, Policy Director, Community Alliance with Family Farmers (CAFF), a non-profit organization that advocates for California’s family farmers and sustainable agriculture, posted the following FSMA Policy Update:

The comment period on FDA’s proposed rules for the Food Safety Modernization Act (FSMA) is now closed. Almost 20,000 comments were submitted to FDA. Most agricultural organizations joined in calling for another draft rule and further comments, given how much disagreement there was with some of FDA’s proposals. We will now wait and see if the FDA takes this good advice.

Here in California, we continue to work on a series of legislative bills that limit the food safety requirements for small producers and in many cases, allow them to self-certify and avoid inspections and audits.

This effort began with the cottage food bill in 2012, and continued with the CSA bill in 2013. Additionally, it will be taken up in several bills in 2014, including those on reforming farmers’ markets, allowing small-scale sales of raw milk, and setting rules for urban gardens.

Our goal is to create sensible and low-cost food safety best practices for producers not subject to the federal rules, allowing beginning farmers and direct marketing to continue to flourish in California.

We also continue to offer free assistance to farmers on food safety.

RED BLOTCH ON GRAPEVINES NOT NEW

New Test Identifies Virus Already Present

By Laurie Greene, Associate Editor

TODAY, in the midst of new Red Blotch discoveries, Monica Cooper, UCCE Viticulture Farm Advisor in Napa County told California Ag Today that Red Blotch is not new to California; it is a newly-discovered virus that affects grapevines. “We have seen it for awhile, but it has been confused with leaf roll disease that also causes leaf reddening, and it had not yet been genetically identified.”

Cooper said, “The real difference is that before we merely saw symptoms; now we can identify the virus with a test.”

Grapevine red blotch-associated virus (GRBaV) is the latest addition to the list of more than 75 graft-transmissible agents in grapevines. The National Clean Plant Networksays this recently reported virus is associated with the emerging red blotch disease first described on research plots and commercial vineyards of Cabernet Sauvignon in Napa Valley in 2008.

The USDA Agricultural ResearchService reports that in 2008, these grapevines exhibited symptoms resembling leafroll disease, and produced clusters with reduced sugar content causing delayed harvests.

Among the grapevine pests and diseases, only leafroll diseases exhibit similar canopy symptoms, cause reduced sugar accumulation in the berries and occasionally exhibit poor color development in some clusters and increased acidity as well. Potassium deficiency also has a similar appearance.

Laboratory tests in 2008 failed to detect any of the leafroll and rugose wood viruses in these samples. The disease symptoms were not caused by nutritional deficiencies, stress, bacteria, fungi and/or nematodes.

Red Blotch diagnosis based on the leaf symptoms can be challenging. A new molecular test based on genetic sequences was developed in 2012 by researchers at Foundation Plant Services at UC Davis, USDA and Cornell scientists.

This new PCR test is now commercially available, and the virus can be detected in the petioles of basal leaves, muchbefore the onset of symptoms.

Identification of the grapevine red blotch-associated virus (GRBaV) is the first step in a process to collect more information on the virus and the disease. Ongoing studies are investigating many aspects of virus and disease, for instance: researchers are investigating the exact role of GRBaV in red blotch disease, seeking more information on the genomic sequence of this DNA virus, and investigating the transmission of the virus and improved detection techniques.

The virus has been shown to be graft-transmissible and is likely responsible for the wide geographic distribution. Thus far, disease symptoms have been observed in vineyards planted with red grape varieties such as Cabernet Franc, Cabernet Sauvignon, Merlot, Petite Sirah, Petit Verdot and Zinfandel.

Cooper says that the disease is widespread throughout California. Similar viruses have been found in vineyards in New York, Pennsylvania and Canada.

Cooper says we don’t know enough about the disease. We don’t know the different varieties, the rootstocks of choice, how it moves (by insect or in plant materials only). It is also not known if the disease has any effect on fruit yield or if it causes vine decline.

As Cooper summed up, “There will be no quarantine. This is not an actionable pest; we just do not know enough about it.”

So, what are growers to do?

Cooper recommends use of planting material free of known pathogens, given that once viruses are present in the vineyard there is no known cure.

The symptoms generally start appearing in late August through September as irregular blotches on leaf blades on basal portions of shoots. The grapevines with red blotch stop accumulating soluble solids and end the season at four to six degrees brix lower than uninfected vines.

If grapevines, red or white, are producing fruit with Brix values lower than expected and are not showing classic leafroll-like symptoms, contact your local ViticultureFarm Advisor.

Test your vines.

GROWERS PLAN NEW STRATEGIES TO COMBAT WEED RESISTANCE

BASF Survey Shows Majority Of Growers Face Glyphosate-Resistant Weed

Three out of four growers who participated in a recent survey by BASF suspect that glyphosate resistance is a cause of their tough-to-control weeds. As a result, a staggering 76 percent of these growers have already changed their weed management program to address resistance.

In addition, many growers have experienced lower yields, which they attribute to resistant weeds. These growers have also spent more time scouting and invested more money in their crops due to resistant weeds.

In the survey, growers identified how they plan to change their programs in 2014. More than two-thirds of growers indicated that they would be applying a pre-emergence herbicide this season and more than half of growers are planning to add an additional herbicide to their existing program. Additionally, 50 percent of growers plan to use more than one site of action and 47 percent said they plan on using overlapping residual herbicides to control resistant weeds.

“These results show that growers are beginning to understand the need for a comprehensive weed management approach,” said Greg Armel, Ph.D., Technical Market Manager, BASF. “Growers are realizing the importance of using residual herbicides and multiple, overlapping herbicide sites of action.”

The survey also highlighted the weeds that growers found the toughest to control in 2013. Nearly two-thirds of respondents said waterhemp was the most difficult to control, while 54 percent said that ragweed species were the toughest to control. Lambsquater and marestail were also identified as difficult weeds.

To combat these tough weeds, growers are now looking for solutions to meet their specific crop needs.

With half of the herbicide sites of action currently available in the U.S., BASF is a key resource for growers fighting resistant weeds.

CALIFORNIA RANCHERS WEIGH OPTIONS AS DRY SPELL LINGERS

Ranchers Take Measures to Survive Dry Weather

TODAY, the California Farm Bureau Federation reports this fall’s rainy season has not brought the relief cattle ranchers had hoped for since last spring’s lack of precipitation deteriorated California pastures.

Some moisture late November helped fill stock ponds and started seasonal streams flowing, said Glenn Nader, a University of California Cooperative Extension livestock and natural resources advisor for Yuba, Sutter and Butte counties. But in terms of growing feed, the rain came a little late.

“Things may germinate, but they’ll just sit there,” Nader said. “There’s not going to be any rapid growth until March—unless we get an unusually warm December.”

Because the springtime was so dry, ranchers who move their cattle to summer pastures did not have much dry feed for their animals to come home to this fall. And where they do have dry feed, stock water has been very limited, and hauling water can be cost-prohibitive, Nader noted.

“Many of them were hoping they’d get an early germination and have green feed to go into the winter with, and that just didn’t occur,” he said.

The state will still need successive rains this winter and enough ground moisture to support decent growth next year, Nader added.

For now, ranchers will have to find other forage sources, including dry feed and supplementing with hay, he said, noting that less hay production this year due to drought has led to tight supplies and high prices.

“People can quickly feed themselves into a negative cash flow with today’s hay prices,” he said. “That’s why a lot of people are looking at alternative dry matter sources such as corn stover, rice straw and other things, to try and cheapen up those costs.”

Andy Domenigoni, who runs cattle on dryland pasture in Riverside and Tulare counties, said in addition to feeding hay since September, he buys culled oranges, lemons, avocados and other vegetable and fruit byproducts from a local packinghouse to supplement until range conditions improve.

He weaned his calves early this year and thinned about 25 percent of his cows when he saw how low he was getting on feed. He had already culled about 15 percent of his herd last year and sold all of his heifers the last two years, so he has no replacements.

The aggressive herd liquidations across the nation in recent years due to drought have kept the cattle market strong for producers, Domenigoni said, and it will take some time before U.S. cattle ranchers can begin to fully rebuild after years of contraction.

“When cattle numbers are short, the prices stay up, and those who can afford to stay in the business will make some money,” he said.

San Joaquin County cattle rancher Rich Ricesaid high cattle prices have been good for those who have cattle to sell, but if producers have to sell their cows due to lack of feed, they won’t have many to sell the following year.

“If you’re selling the cows, you’re selling the factory, because they make a calf to sell every year,” he said. “Sure, she’s going to bring pretty good money, but that’s not really what you want to do.”

Because he runs his cattle on rented ground—both dryland and irrigated pasture—that land will cost him money even if he cannot turn cattle out on it. For the moment, he said he’s been able to move his cattle to various properties to stretch the feed, but he’s had to send some of his yearlings to feedlots. And while he hasn’t reduced his numbers yet, he said with hay prices getting higher, it would not be feasible for larger operations like his to obtain enough hay and labor to feed all his cattle.

For Nevada County rancher Jim Gates, who raises grassfed cattle on irrigated pasture, dry weather has increased his production costs considerably because he has to keep his animals on range much longer and must buy more hay than usual.

He noted the Nevada Irrigation District shut off its water on Oct. 15, so he now depends totally on rainfall to grow his pasture. He said his region received about two inches of rain last month, enough to germinate grasses in some areas of the pasture—but north winds immediately dried them out.

Santa Cruz County rancher John Pisturinosaid after the state’s last drought several years ago, he began expanding his herd, but he may now have to reduce his numbers again if the season does not improve. He’s been supplementing with hay since September and has enough to see him through January or February, at which time he hopes grasses will be long enough to support his cattle.

Denis Lewis, who raises purebred Angus bulls in San Joaquin County, said even though his cattle are on irrigated pasture, he has stopped irrigating because the cooler temperatures in recent weeks have not been conducive to growing grass. That means he has had to increase his hay purchases by about 30 percent, while reducing his herd by about 10 percent. He said he’s concerned about how the drought will affect the state’s dryland hay production.

“Hay growers are banking on the rain to make it grow, and if we don’t get any rain for two or three months, then what has germinated will die,” he said.

Siskiyou County rancher Leonard Gorden said not only is the drought affecting cattle producers—some of whom will go out of business or reduce their numbers so severely that ranching will no longer be a business but a hobby—but he said he’s concerned about the long-term effect it will have on the entire U.S. beef sector.

“Eventually, if cattle numbers get too low and the price of beef continues to get higher because of that, I think our consumers will try to go to alternative protein sources,” he said.

USDA, EPA PARTNER TO SUPPORT WATER QUALITY TRADING

Water Quality Trading Upcoming for California Growers

The U. S. Department of Agriculture (USDA) and the Environmental Protection Agency (EPA) announced TODAY an expanded partnership to support water quality trading and other market-based approaches that provide benefits to the environment and economy.

“New water quality trading markets hold incredible potential to benefit rural America by providing new income opportunities and enhancing conservation of water and wildlife habitat,” Agriculture Secretary Tom Vilsack said. “Additionally, these efforts will strengthen businesses across the nation by providing a new pathway to comply with regulatory requirements.”

“EPA is committed to finding collaborative solutions that protect and restore our nation’s waterways and the health of the communities that depend on them,” said EPA Administrator Gina McCarthy. “We’re excited about partnering with USDA to expand support for water quality trading, which shows that environmental improvements can mean a better bottom line for farmers and ranchers.”

Water quality trading is an innovative approach for achieving water quality goals at lower cost. Water quality trading can also provide additional environmental and economic benefits, such as air quality improvements, enhanced wildlife habitat, carbon capture and storage, and new income and employment opportunities for rural America.

Where appropriate, trading is a powerful and effective market-based approach to achieving cleaner water. Trading is based on the fact that sources in a watershed can face very different costs to control the same pollutant. Trading programs allow facilities to meet regulatory obligations by purchasing equivalent or superior pollution reductions from another source — achieving water quality improvements in a cost-effective manner.

EPA and USDA are working together to implement and coordinate policies and programs that encourage water quality trading. The Department and the Agency will identify opportunities to work collaboratively to help improve water quality trading programs across the country. Cooperative management and technical assistance will improve resource management and public services, and accelerate implementation.

USDA and EPA will:

Coordinate and enhance communications and outreach to states, agricultural producers, regulated sources, and interested third parties on water quality trading;
Engage expertise across agencies in the review of grants, loans or technical assistance programs focused on water quality trading;
Share information on the development of rules and guidance that have the potential to affect water quality trading;
Collaborate on developing tools and information resources for states and credit generators to guide decision making, reduce costs in program design and implementation, improve environmental performance, and foster consistency and integrity across regional initiatives;
Co-host a workshop by 2015 to share tools and resources available to assist in stakeholder decision making and opportunities.

The purpose of this policy is to support states, interstate agencies and tribes as they develop and implement water quality trading programs for nutrients, sediments and other pollutants where opportunities exist to achieve water quality improvements at reduced costs.

For a basic introduction to water quality trading, please check the EPA website site.

EPA’s Water Quality Trading Assessment Handbook will help users decide whether water quality trading will work in their watershed and when and where trading is likely to be the appropriate tool for achieving water quality goals.

CITRUS GROWER TAKES PRECAUTIONS AGAINST FREEZE

Protecting Citrus Against A Possible Freeze

By Laurie Greene, Associate Editor

A Wind Machine Standing By to Help Protect

Citrus as a Freeze Moves into the Valley.

Philip LoBue, President and CEO, LoBue Citrus, a full-service grower, packer, and citrus shipper, based in Tulare County, spoke with California Ag Today.

According to LoBue, this week is a typical freeze event, though slightly earlier than usual. So, he is taking ordinary precautions with his citrus by using well water and wind machines.

Generally, early afternoon water application using standard irrigation, in this case micro-sprinklers within rows, creates a microclimate effect of surface heat. As the temperature drops at night, water freezes and gives off energy (heat), benefitting the trees. In the sunlight the next day, water melts into the ground allowing the ground to hold more heat during the day, and so the cycle continues.

The freeze stirs up an inversion layer 30 feet above ground at the treetops. Tonight’s inversion in the central part of the central San Joaquin Valley will be weak according to LoBue because the inversion’s elevation will be only one or two degrees warmer, and not six degrees for example.

The extent of freeze damage on crops depends upon the actual temperature, length of exposure time, and precautions taken. In citrus groves, the initial freeze damage starts outside of the grove on its borders and on the exterior of the fruit exposed on the treetops. The exterior rind of the fruit becomes physically damaged before the interior is affected. Exterior rind ice marks and other visual markers change the fruit’s export quality and value. As the freeze persists, the interior of the fruit becomes susceptible to damage.

LoBue says farmers are already taking additional standard precautions such as checking batteries for diesel or propane wind machines and copper or aluminum wiring for electric wind machines.

Of note, a brutal freeze on December 23, 1991, destroyed all fruit yet to be harvested.As a result, LoBue Bros. (former company name) shut down for most of the year. When it became apparent that government employment programs were inadequate in addressing the needs of unemployed workers, the LoBue staff and management secured both private sector and additional government assistance to help workers obtain food and shelter until the next season’s crop. LoBue Bros. received statewide recognition for its efforts on behalf of these workers.

Nearly 80 years in business, LoBue Citrus is an independent, family-owned grower, packer and shipper of fresh citrus and citrus juice products, including navel oranges, mandarin oranges, specialty citrus, lemons and juice.
