By Mikenzi Meyers, Contributing Editor

The Annual Alfalfa and Forage Field Day is fast approaching, and it’s one you won’t want to miss! The field day will be held on Thursday, September 19th at the UC Kearney Agricultural Research and Extension Center, and cover a variety of topics from forages to crops.

Nicholas Clark, certified Crop and Farm Advisor in Agronomy and Nutrient Management for the University of California Cooperative Extension (Kings, Tulare and Fresno), is eager to spread the word and increase attendance for what is sure to be an educational day for all attendees.

“We try to make it a very comprehensive program in terms of covering the bases of different forages that are popular or emerging in popularity in the southern portion of the San Joaquin Valley,” Clark explained.

Although alfalfa and other forages are on the forefront of the event, Clark added that management practices, silage crops, and possibly also sugar beets are up for discussion.

Make sure to mark your calendars for the Annual Alfalfa and Forage Field Day on Thursday, September 19th at the UC Kearney Agricultural Research and Extension Center.

Bio-Control for Strawberry Growers

Strawberry Growers Lean on Biologicals to Manage Pest

By Jessica Theisman, Associate Editor

California Ag Today recently met with Surendra Dara, a UC Cooperative Extension entomologist based in San Luis Obispo County. According to Dara, California strawberry growers follow many sustainable options.

“Growers are well-educated and have a support system that provides information to them very regularly,” Dara said.

Growers try to apply as much of the IPMs as possible, but there is always a lot more scope in terms of using non-chemical alternatives. That is an area that has room to grow.Strawberries

“The more we know about the options and their potential, they can be more adopted,” Dara said.

He explained that the strawberry growers often lean on biological insects such as beneficial mites that treat those damaging insects. It’s all part of IPM.

The insects are used outdoors along with in greenhouses.

“A bio-control is very well done in strawberries for mite control, but we do not have similar natural enemies for other pests,” Dara said.

There are botanical and microbial options for pest and disease management, and a lot of work is being done about understanding how they work and placing them in the right strategy.

“So, there is definitely plenty of options for us,” Dara said.

UC DroneCamp Coming June 18-20

UC Offers Drone Workshop for Mapping, Research, and Land Management

By Pam Kan-Rice, UC Ag & Natural Resources

People who are interested in using drones for real-world mapping are invited to attend a three-day intensive drone workshop in the Monterey Bay area. The third annual DroneCamp will be offered from June 18 to 20 by UC Agriculture and Natural Resources’ Informatics and GIS Program. No experience with drone technology is needed to participate.

Drone mapping involves taking high-resolution photos with drones and stitching them together with software to make extremely accurate, orthorectified maps. More difficult than videography, it is widely used in agriculture, construction, archeology, surveying, facilities management, and other fields. DroneCamp will cover all the topics someone needs to make maps with drones, including:

  • Technology—the different types of drone and sensor hardware, costs and applications
  • Drone science—principles of photogrammetry and remote sensing
  • Safety and regulations—learn to fly safely and legally, including tips on getting your FAA Part 107 Remote Pilot Certificate
  • Mission planning—flight planning tools and principles for specific mission objectives
  • Flight operations—hands-on practice with both manual and programmed flights
  • Data processing—processing drone data into orthomosaics and 3D digital surface models; assessing quality control
  • Data analysis—techniques for analyzing drone data in GIS and remote sensing software
  • Visualization—create 3D models of your data
  • Latest trends—hear about new and upcoming developments in drone technology, data processing, and regulations

On the first day, DroneCamp instructors will discuss drone platforms, sensor technologies, and regulations. On the following two days, participants will receive hands-on instruction on flying safely, using automated flight software, emergency procedures, managing data, and turning images into maps using Pix4D mapper and ArcGIS Pro.

Registration is $900 for the general public and $500 for University of California students and employees. Registration includes instruction, materials, flight practice and lunches. Scholarships are available.

This year, DroneCamp is being held in conjunction with the Monterey Bay DART (Drones Automation & Robotics Technology), which is holding an industry symposium on Friday, June 21. DroneCamp participants get a $50 discount to attend the symposium.

For more information and to register for DroneCamp, please complete the registration form at http://igis.ucanr.edu/dronecamp. Registration fees are due by June 1, 2019.

Protecting Melons From Silver Leaf Whitefly

Avoid Planting Near Earlier Planted Crops

By Patrick Cavanaugh, Editor

Silver leaf whitefly can be a severe yield-robbing pest in melons, but there are ways to prevent the damage, according to Tom Turini, a UCANR Vegetable Crops Adviser in Fresno County.

“A tactic is going to depend upon planting. If you’re able to put the crop into an area where you’re not next to earlier planted melons or cotton or known sources of whitefly, your likelihood of experiencing damaging whitefly levels is going to be lower,” Turini said. “Growers can’t always do that, but that’s part of the approach when you can. You’ll limit your risk.”

Tom Turini, UCANR Farm Advisor, Fresno County

Turini said the pest could mainly be a problem when you’re putting in those late melon fields when whitefly populations are higher.

“Whiteflies are not good fliers, so when you put those fields in areas where you don’t have sources of whitefly nearby then you will have less pressure for sure,” Turini said.

“Then there are some insecticide programs that you can look at, particularly when you know you’re going to have pressure,” Turini explained. “If you’re coming into high temperatures, and you’ve got late-planted melons, you may want to start with soil-applied insecticides, through the drip. It could be Admire; also Sivanto is a newer material that that has registration and has shown efficacy in desert production areas, which have much higher pressures and more consistent pressures than we do in the San Joaquin Valley.”

New Series of Nitrogen Management Advice Available

UC ANR Publishes Nitrogen Management Advice for Fruit, Nuts, and Other Crops

By Pam Kan-Rice UC Agriculture & Natural Resources

California growers can download a new series of publications summarizing efficient nitrogen management practices from UC Agriculture and Natural Resources. The publications are designed to assist growers in complying with state regulations for tracking and reporting nitrogen fertilizer applied to crops, in an effort to prevent nitrogen from leaching into groundwater.

The science-based publications are associated with a series of trainings for growers and Certified Crop Advisers to develop efficient nitrogen management practices, an effort coordinated by UC ANR’s California Institute for Water Resources.

“Our role is to provide farmers, agricultural consultants and policymakers the best science possible for making decisions on managing and protecting California groundwater,” said Doug Parker, director of the water institute.

The free publications—created from training materials, lessons learned from the training sessions and from additional UC research—can be downloaded at http://ucanr.edu/nmgmtpublications.

The following publications are now available for download:

·         Principles of Nitrogen Cycling and Management

·         Irrigation and Nitrogen Management

·         Nitrogen Management for Nut Crops

·         Nitrogen Management for Deciduous Fruit and Grapes

·         Nitrogen Management for Citrus and Avocado

·         Nitrogen Management for Cool-Season Vegetables

·         Nitrogen Management for Strawberry Production

·         Nitrogen Management for Processing Tomato

·         Nitrogen Management for Corn on California Dairies

The publications were authored by Parker of California Institute for Water Resources; Patrick Brown, professor in the UC Davis Department of Plant Sciences; Allan Fulton, UC Cooperative Extension advisor, Tehama County; Tim Hartz, UC Cooperative Extension specialist emeritus, UC Davis Department of Plant Sciences; Dan Munk, UC Cooperative Extension advisor, Fresno County; Daniel Geisseler, UC Cooperative Extension specialist, UC Davis Department of Land, Air & Water Resources; Michael Cahn, UC Cooperative Extension advisor, Monterey, Santa Cruz and San Benito counties; Richard Smith, UC Cooperative Extension advisor, Monterey, Santa Cruz and San Benito counties; Marsha Campbell, UC Cooperative Extension advisor emeritus, Stanislaus County; Sat Darshan Khalsa, UC Davis project scientist; and Saiful Muhammad, UC Davis graduate student.

Developed in 2014, the training program has been offered at 11 different locations around the state, most recently in Fresno. More than 1,000 Certified Crop Advisers have taken the training.

“Based on course evaluations, the percentage of participants with good-to-complete understanding of nitrogen management increased after the training,” Parker said. “In addition, the participants found the presenters very knowledgeable and informative. Most importantly, the majority of participants felt they were better prepared to address nitrogen mitigation regulatory requirements after the training.”

The nitrogen management training curriculum was developed by a group of UC ANR faculty, specialists and advisors. The first day focuses on the nitrogen cycle in crop production systems, nitrogen sources, irrigation and nitrogen management, and nitrogen budgeting. The second morning covers annual and permanent crops and nitrogen planning practices.

For more information on the nitrogen management training materials, visit http://ciwr.ucanr.edu/NitrogenManagement.

The Nitrogen Management Training and Certification Program is a joint effort between the California Department of Food and Agriculture, UC Agriculture and Natural Resources, California Association of Pest Control Advisers’ Certified Crop Adviser Program and the Regional Water Boards.

University of California Agriculture and Natural Resources researchers and educators draw on local expertise to conduct agricultural, environmental, economic, youth development and nutrition research that helps California thrive. Learn more at ucanr.edu.

Water Rights Holders Must Measure Stream Diversions

UC Cooperative Extension Offering Water Measurement and Reporting Courses April 4

News Release

California water rights holders are required by state law to measure and report the water they divert from surface streams. For people who wish to take the water measurements themselves, the University of California Cooperative Extension is offering training to receive certification April 4 in Redding and Woodland.

At the workshop, participants will:

  • Clarify reporting requirements for ranches.
  • Understand which meters are appropriate for different situations.
  • Learn how to determine measurement equipment accuracy.
  • Develop an understanding of measurement weirs.
  • Learn how to calculate and report volume from flow data.

UC Cooperative Extension is offering a limited number of trainings in 2019. The next training will be held at Shasta College Farm and Yolo County Fairgrounds:

  • Yolo County Fairgrounds in Woodland – Register at http://cecapitolcorridor.ucanr.edu or by emailing Morgan Doran at mpdoran@ucanr.edu or calling the UCCE office in Yolo County at (530) 666-8143. Training will begin at 2 p.m. and should conclude by 5 p.m.

Background on the water diversion law

Senate Bill 88 requires that all water right holders who have previously diverted or intend to divert more than 10 acre-feet per year (riparian and pre-1914 claims), or who are authorized to divert more than 10 acre-feet per year under a permit, license or registration, to measure and report the water they divert. 

Detailed information on the regulatory requirements for measurement and reporting are available on the State Water Resources Control Board Reporting and Measurement Regulation webpage: https://www.waterboards.ca.gov/waterrights. For diversion or storage greater than or equal to 100-acre feet annually, the law requires approval of installation and certification of measurement methods by an engineer, contractor, or other approved professional.

To make it easier for farmers and ranchers to comply with the law, the California Cattlemen’s Association worked with Assemblyman Frank Bigelow on a bill that would allow people to get certified to take the measurements themselves. Assembly Bill 589 became law on Jan. 1, 2018.

Until Jan. 1, 2023, this bill allows anyone who diverts water and has completed an instructional course on measurement devices and methods administered by UC Cooperative Extension, including passage of a proficiency test, to be considered qualified to install and maintain devices or implement methods of measurement. The bill requires UC Cooperative Extension and the water board to jointly develop the curriculum for the course and the proficiency test.

First-Ever UC Cost Study for Primocane-Bearing Blackberries Released

Primocane-Bearing Extends Production Season

By Pam Kan-Rice, UC ANR

The first-ever cost study of primocane-bearing blackberries in California has been published by UC ANR’s Agricultural Issues Center and UC Cooperative Extension. With primocane-bearing, growers can extend the blackberry production season.

“What differentiates primocane-bearing blackberry from the traditional floricane-bearing is that it bears fruit in the first year rather than the second,” explained co-author Mark Bolda, a UC Cooperative Extension advisor.

“Which, of course, opens a world of opportunity for growers, since they are able to produce fruit in the first year rather than the second, as has traditionally been the case,” Bolda said. “That’s what makes this study so interesting to us.”

Primocanes are the green, vegetative stalks of the blackberry plant, generally the first-year cane. The second year, they become floricanes, flowering and fruiting. 

The study presents sample costs to establish, produce, and harvest primocane-bearing blackberries in the Central Coast region of Santa Cruz, Monterey, and San Benito counties.

The analysis is based on a hypothetical well-managed farming operation using practices common to the region. The costs, materials and practices shown in this study will not apply to all farms. Growers, UC ANR Cooperative Extension farm advisors, and other agricultural associates provided input and reviewed the methods and findings of the study.

This study assumes a farm operation size of 30 contiguous acres of rented land, with primocane-bearing blackberries for fresh market planted on 15 acres. The crop is hand-harvested and packed into 4.5 pound trays. During the establishment year, there is a four-month harvest: July through August. Primocane blackberries can produce fruit on first-year growth. There is also a four-month harvest for each of the four production years.

The authors describe assumptions in detail and present a table of costs and returns based on those assumptions about production, input materials, prices, and yields. A ranging analysis shows the impact on net returns of alternative yields and prices. Other tables show the monthly cash costs; the costs and returns per acre; hourly equipment costs; and the whole farm annual equipment, investment, and business overhead costs.

The study also has an expanded section on labor, which includes information on California’s new minimum wage and overtime laws.

“This work investigating the economics of a newer cultural system for our area came out of a close collaboration between UCCE academics and area growers,” said Bolda, who serves Santa Cruz, Monterey and San Benito counties, “so the level of detail and accuracy is outstanding.”

Free copies of this study and other sample costs of production studies for many commodities are available. To download the cost studies, visit the UC Davis Department of Agricultural and Resource Economics website at https://coststudies.ucdavis.edu.

The cost and returns studies program is funded by the UC Agricultural Issues Center and UC Cooperative Extension, both of which are part of the UC Division of Agriculture and Natural Resources, and the UC Davis Department of Agricultural and Resource Economics.

For additional information or an explanation of the calculations used in the studies, contact the UC Agricultural Issues Center at (530) 752-4651 or UC Cooperative Extension advisors Mark Bolda (831) 763-8025 or Laura Tourte (831) 763-8005 in Santa Cruz County.

Helpful Tips for Fighting Bindweed

Multiple Herbicides Can Help with Management

By Mikenzi Meyers, Associate Editor

Field bindweed is continuing to inconvenience farmers and ranchers. However, Scott Stoddard of the UCANR Cooperative Extension in Merced County has some tips on how to control it.

Scott Stoddard

Stoddard explained that the solution isn’t as simple as applying one herbicide, but using a combination might provide some results.

“You have to combine the Roundup with something like a Treflan, and then combine that maybe with some applications of herbicides,” he said.

Stoddard further added that although more successful than applying Roundup alone, even stacking the herbicides will only provide marginal to good control.

The best approach to getting rid of this stubborn weed? Stoddard recommends rotating your field with Roundup Ready varieties so that the herbicide can be more effective on non-Roundup Ready crops.

“For example, a Roundup Ready cotton or corn will clean up a field for the following year for things like tomatoes or melons. In that particular case, Roundup can be very useful,” he said. “Otherwise get it in when you can. If you can apply it before you transplant, or if the bindweed does come out before your transplant that’s when Roundup should be used.”
