New research has identified critical levels of predators that impact economic spray decisions for whiteflies. By working with the beneficials found naturally within a field, reliance on chemical controls could effectively be reduced.
Interactions Between Insects & Weeds in Desert Crops - July 2018
There is a positive correlation between weeds and insects. This article describes the relationship between weed management and insects. It details how weeds can be a refuge for beneficial insects and how they can also act as a reservoir for insect pests. The impact that weeds have on insecticide application is also discussed.
Cotton IPM: A Quiet Revolution Reduces Costs, Losses and Risks for Arizona’s Cotton Growers
New technologies have enabled cotton growers to reduce their spray applications significantly while achieving among highest cotton yields worldwide. Arizona now produces the highest yielding cotton in the world, well over 1,500 pounds of fiber per acre, far exceeding the U.S. national average of about 750 pounds per acre. These technologies also help growers implement more ecologically based, sustainable IPM programs and become less dependent on broadly toxic insecticides.

Using selective chemistries is safer for the user and environment. This includes the beneficial predators found within fields that are important for controlling pests such as whiteflies and Lygus bugs. Selective chemistries are an important component of Arizona’s insect cotton IPM program. Current research is being conducted on the newest chemistries to determine their selectivity towards non-target organisms, such as beneficials.
