Last month, a California grape farmer was fined $10,000 for using a pesticide in violation of the label, then packing and attempting to sell the tainted fruit. DPR detected the residues of a pesticide on the produced that was not registered for use on grapes.
Cases like this are rare in California but remind growers how important it is to apply pesticides correctly by following all pesticide label directions. The California Department of Pesticide Regulation (DPR) runs the most extensive Pesticide Residue Monitoring Program in the nation and is hard at work ensuring that the fruit and vegetables we purchase and consume are free from illegal pesticide residues.
Understanding and following label instructions is the focus of a new online course developed by the University of California Agriculture and Natural Resources Statewide Integrated Pest Management Program (UC IPM).
The program, Proper Pesticide Use to Avoid Illegal Residues, is targeted to those who apply pesticides or make pesticide recommendations. It explains what pesticide residues are, how they are monitored, and highlights important residue-related information from several sections of pesticide labels. In addition, the course identifies the following as the most important factors leading to illegal residues:
- Using a pesticide on a crop for which it is not registered
- Applying pesticides at an incorrect rate
- Ignoring preharvest intervals, re-treatment intervals, or plantback restrictions
Course participants are presented with several real-life scenarios. They must search through actual pesticide labels to determine if the scenario illustrates proper use of pesticides or if the described situation could potentially lead to illegal residues.
The overall goal of this course is to have participants follow pesticide label instructions when they return to the field. Following the label can eliminate incidences of illegal pesticide use.
Proper Pesticide Use to Avoid Illegal Residues is published just in time for pest control advisers and pesticide applicators who are still a few units short to renew their licenses or certificates with DPR. The course has been approved for two hours of Pesticide Laws and Regulations continuing education units (CEUs) from DPR and costs $40. If you don't need CEUs, but are still interested in viewing the course content, check it out for free on YouTube.
DPR recommends that renewal packets be submitted before Nov. 1 in order to receive your renewed license or certificate by Dec. 31, as the processing time can take up to 60 days. For additional online courses that UC IPM offers, visit the online training page.
Our mission at the University of California Agricultural and Natural Resources (UC ANR), Statewide Integrated Pest Management Program (UC IPM) is to protect the environment by reducing risks caused by pest management practices. UC IPM developed Bee Precaution Pesticide Ratings to help pest managers make an informed decision about how to protect bees when choosing or applying pesticides. You can find and compare ratings for pesticide active ingredients including acaricides (miticides), bactericides, fungicides, herbicides and insecticides, and select the one that poses the least harm to bees.
Ratings fall into three categories. Red, or rated I, pesticides should not be applied or allowed to drift to plants that are flowering. Plants include the crop AND nearby weeds. Yellow, or rated II, pesticides should not be applied or allowed to drift to plants that are flowering, except when the application is made between sunset and midnight if allowed by the pesticide label and regulations. Finally, green, or rated III, pesticides have no bee precautions, except when required by the pesticide label or regulations. Pesticide users must follow the product directions for handling and use and take at least the minimum precautions required by the pesticide label and regulations.
A group of bee experts in California, Oregon and Washington worked with UC IPM to develop the Bee Precaution Pesticide Ratings. They reviewed studies published in scientific journals and summary reports from European and United States pesticide regulatory agencies. While the protection statements on the pesticide labels were taken into account when determining the ratings, it is important to stress that UC IPM's ratings are not the pollinator protection statements on the pesticide labels. In a number of cases, the ratings suggest a more protective action than the pesticide label.
The UC IPM ratings also include active ingredients that may not be registered in your state; please follow local regulations. In California, the suggested use of the Bee Precaution Pesticide Ratings is in conjunction with UC Pest Management Guidelines (for commercial agriculture) and Pest Notes (for gardeners). Each crop in the UC Pest Management Guidelines has a link to the Bee Precaution Pesticide Ratings database and provides guidance on how to reduce bee poisoning from pesticides.
The Vertebrate Pest Conference is held every two years, usually in California, in cooperation with the Pesticide Applicators Professional Association (PAPA). The leading authorities with vertebrate management expertise from around the world congregate to present the latest research and extension information.
The conference is intended for animal control officials, wildlife managers, agricultural producers, pest control advisers, consultants, educators, researchers and natural resource managers. California Department of Pesticide Regulation and California Department of Public Health continuing education units are available for participants. Special symposia at the conference include bird, wild pig, and urban coyote management.
At the Vertebrate Pest Conference, experts will share the latest information about coyote attacks, human-coyote conflicts, and present several talks on coyote management, including hazing.
Niamh Quinn, a UC Cooperative Extension vertebrate pest advisor based at the UC South Coast Research and Extension Center in Orange County, is one speaker on the growing problem of urban coyotes. With over 3 million people in Orange County, 8 state parks and beaches, countless city parks and 19 county parks and wilderness areas, conflicts with urban coyotes are bound to happen. Managing coyotes includes managing people's behavior too.
“We can't manage what we can't measure. This conference provides a unique opportunity to discuss ongoing conflicts, especially those related to urban coyote management," Quinn said. "Research is needed to understand urban coyote behavior and if these behaviors are changing as a result of the way we are currently living. Outreach is needed to instruct urbanites on appropriate behavior where coyote conflicts are occurring, and managing coyotes is everyone's concern. We need better and improved strategies for measuring and managing these conflicts.”
One talk at the Vertebrate Pest Conference will be a North American overview of bird damage in fruit crops. Other presentations cover field rodent repellents, food safety, and trapping.
Chlorpyrifos is widely applied to many crops for pest control; the highest percentage on almonds, citrus, alfalfa and cotton. However, the U.S. Environmental Protection Agency has proposed cancellation of its use in agriculture.
"Chlorpyrifos is a tool and over reliance on that tool to help us solve pest problems is going to have environmental impacts and potentially could impact human populations as well," said UC ANR Cooperative Extension advisor David Doll in the Valley Public Radio story.
Romero also spoke to Selma almond grower Bill Chandler at the meeting.
"Don't give up the ship, there's help," Chandler said. "That's why they (UC IPM) had this meeting to say, listen gentlemen, there's these problems. Let's learn how to work with them and see what we can use differently."
