Many factors must be considered when choosing an insecticide, such as cost, efficacy, risk of resistance, and safety to non-target organisms. This Cotton Insecticide Use Guide summarizes the diverse risks of insecticides used to control three pests, helping you make well informed pest management decisions.

Cotton insecticide target efficacy, impact on non-target arthropods and other pesticide risks.

Cotton fleahoppers are present in cotton during early squaring but rarely require chemical control. These piercing-sucking pests feed on small squares and new terminal growth. Cotton at early squaring is at risk for losing fruiting sites due to blasting of small squares, which can delay timeliness of fruiting, however, yield loss is rare.

False chinch bug nymphs, not adults, contribute to significant early-season stand loss in cotton. Best management practices include timely removal of weeds from surrounding fallow or wasteland areas.  Chemical control of nymphs should only be considered during mass migrations when abundant false chinch bugs occur per plant, only where they are entering the field plus 50 feet further into the field, and usually only as a banded application over the crop.

Palmer amaranth (careless weed or pigweed) is a plant native to the desert southwest that has developed resistance to multiple herbicide mechanisms of action (MOAs). In multiple crops, in all major Arizona agricultural areas, Palmer amaranth resistant to glyphosate and ALS inhibitors (e.g., Staple®) can be found. A diversity of control tactics are needed to manage herbicide resistant Palmer amaranth.

Off target movement of the auxin herbicides, 2,4-D and dicamba, will cause substantial injury to downwind, sensitive crops such as cotton, grapes, melons and other broadleaf plants. This publication provides guidelines for preventing off target movement.

This publication summarizes best use practices and label requirements for auxin herbicides.

Off target movement of 2,4-D and dicamba can cause substantial injury to downwind sensitive plants, a potential liability issue for applicators. This short outlines herbicide label requirements and best practices to prevent drift of auxin herbicides. 

Dinitroaniline (DNA or "yellow") preemergence residual herbicide at the beginning of the cotton season provides a foundation for season-long weed management. The discovery of glyphosate-resistant Palmer amaranth in central Arizona last year underscores the importance of diversity in weed control tactics. This short outlines effective use practices for DNA herbicides.

External parasites, such as mites and poultry lice, are common pests on birds, especially in backyard chickens. They feed on the blood and bite skin, feathers, or scales of the bird. A heavy infestation of these pests can result in poor poultry health, reduced growth and egg production, and sometimes can even cause bird deaths. This article provides basic information on how to recognize the signs and symptoms of an infestation, and how to effectively treat infested birds.

The Arizona Pest Management Center uses scientific data and feedback from grower communities to develop comments that inform Environmental Protection Agency (EPA) pesticide registration decisions. Our analysis shows that a high percentage of our comments provide substantive information that influence registration outcomes.
