A guide to the proper use of a sweep net for sampling key pests in cotton.

A guide to protecting young and emerging cotton from flea beetle damage and the factors to consider in determining control options.

A guide to identification, sampling and thresholds for Egyptian alfalfa weevil.

Assassin bugs are "apex" or top predators in the cotton food web contributing to biological control of pests, including Lygus and whiteflies. Two common genera are Zelus and Sinea .

This guide describes "selectivity" and the role that selective insecticides can play in conserving natural enemies while still controlling our two key pests of cotton, whiteflies and Lygus bugs.

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.

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.

La tablas proporcionan una guía para tomar decisiones sobre cuando fumigar para manejar eficazmente mosca blanca. Disponible tanto en inglés como en español.

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.

This guide discusses irrigation issues for small grains production.

Guidelines are provided for rates and timing for fertilization of small grains.

Planting at the optimum time is probably the most important cultural practice in producing high yields of small grains. This guide discusses the impact of planting dates and seeding rates on yields and the probability of frost damage.

For profitable production of small grains, pre-plant soil testing is critical. This guide explains how to take samples and how much fertilizer to apply, based on results.

Different types of harvest aids are available to defoliate cotton and prepare the plants for a successful harvest. This guide identifies the types, rates and seasonal limits for various harvest aids.

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.
