Tank-Mixing Pesticides without Disasters

Tank-mixing several pesticides is a common practice in conducting pest control. Tank mixes can consist of much more than just pesticides, such as fertilizers, micronutrients, and adjuvants. However, applicators must be aware of potential problems given that there are so many potential combinations when combining these products. Manufacturers cannot possibly test for all of these combinations, so both chemical and physical incompatibility are a concern with the practice. This new 4-page document, written by Frederick M. Fishel and published by the UF/IFAS Pesticide Information Office, describes some common-sense practices to help overcome costly tank-mixing errors.

Rodenticides

Rodenticides are pesticides designed to kill rodents, primarily mice and rats. However, rodents are not the only species that can be poisoned by rodenticides. Practically any mammal, including humans, can suffer severe effects from unintentional exposure to rodenticides. Rodenticides vary widely in the hazard they present even though they are all designed to kill animals that are physiologically comparable to humans. This new 4-page publication of the UF/IFAS Pesticide Information Office addresses those hazards for rodenticides currently registered in Florida. Written by Frederick M. Fishel.

Restricted Use Pesticides for Use in Florida

All pesticides are classified according to their toxicity, use pattern, and environmental effects. The two main classifications are unclassified use and restricted use, though unclassified pesticides are commonly referred to as general use pesticides. A restricted use pesticide is one that is for retail sale to and use by only certified applicators or persons under their direct supervision and only for those purposes covered by the applicator’s certification. This document will provide a listing of pesticide active ingredients registered in Florida that are classified as restricted and the reason(s) for the restricted use classification. This 4-page major revision was written by Frederick M. Fishel and published by the UF/IFAS Pesticide Information Office.

Worker Protection Standard: Records of Employee Safety Training

The EPA’s Worker Protection Standard for Agricultural Pesticides (WPS) covers pesticides used in the outdoor and enclosed-space production of plants on farms, forests, and nurseries, as well as greenhouses. The WPS requires agricultural employers to take steps to reduce pesticide-related risks when agricultural workers and pesticide handlers are exposed to these pesticides. The EPA has made several changes to the WPS since it was fully implemented in 1995, and this new 3-page document addresses maintaining records of worker and handler training under the revised WPS, including a sample employee-training verification. Written by Frederick M. Fishel and published by the UF/IFAS Pesticide Information Office.

Toxicity of Common Indoor Household Insecticides Registered in Florida

Insecticides are designed to control insect pests, but they can also be toxic (poisonous) to desirable plants and animals, including humans. Some pesticides are so highly toxic that very small quantities can kill a person, and almost any pesticide can make people ill if they are exposed to a sufficient amount. Because even safe pesticides, such as those intended for household use, can irritate the skin, eyes, nose, or mouth, it is a good idea to understand how pesticides can be toxic so you can follow practices designed to reduce or eliminate your exposure to them. This new 3-page document addresses the acute toxicity of common indoor household insecticide active ingredients registered in Florida and provides a table with mammalian toxicity values for each of these insecticides.

Avicides

By and large, birds are beneficial because they provide enjoyment and recreation to humans and are vital to ecosystem balance. However, occasionally some species can compete with human interests. When these situations occur, some forms of control may become necessary. Avicides are pesticides designed to kill or repel pest birds. This new 2-page document addresses those avicides currently registered for use in Florida. Written by Frederick M. Fishel and published by the UF/IFAS Pesticide Information Office.

Pesticide Recordkeeping Form for Florida Applicators

This new 5-page document provides a form containing the required elements to include on a record of pesticide application for meeting the restricted use pesticide and Worker Protection Standard (WPS) requirements. An example application record and an explanation of the required elements is provided. This is not a required form because there are other methods to keep records if they contain the required information. Handwritten notes, electronic records, and other recordkeeping software systems are also acceptable. Written by Frederick M. Fishel and published by the UF/IFAS Agronomy Department.

Worker Protection Standard: Requirements for Commercial Pesticide Handler Employers

Herman Brown, a University of Florida agricultural assistant, sprays pesticide on transgenic rice plants in a greenhouse in Gainesville -- Friday, Oct. 10, 2003. Researchers at UF's Institute of Food and Agricultural Sciences are adding a gene to the plants to protect them from bacterial blight, which is a major disease for rice farmers in Africa and Southeast Asia.

Worker Protection Standard: Requirements for Agricultural Employers of Workers and Handlers

Pesticide testing.

Safety is a high concern for agricultural employers whose workers deal with hazardous materials, such as pesticides.
