New online course from UC IPM helps growers prevent illegal pesticide residues

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.  Just last month, DPR detected residues of a pesticide not registered for use on grapes and fined the grower $10,000 for using a pesticide in violation of the label and for packing and attempting to sell the tainted produce.

Cases like this are rare in California but remind growers how important it is to apply pesticides correctly by following all pesticide label directions.  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).

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 or against a pest 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.
