Pesticide Application and Equipment in Greenhouses

(book excerpts)

When developing an integrated pest management strategy, it is important to know the target pests, their economic threshold levels, and multiple control strategies that can minimize pesticide inputs in the greenhouse. The objective in applying pesticides in greenhouses is to deliver an effective, uniform dose to a target area in a safe and timely manner. Selecting the correct pesticide for the job is very important to the success of a pest management program, but equally important is the equipment and application technique used to apply the pesticide. The equipment chosen for the application of pesticides must be properly selected to allow the chemical to reach the target at the proper rate and with sufficient coverage. The pesticide label will specify the application rate, spray volume, crop, and application methods or restrictions as to where the product can be used. The application equipment used in the greenhouse may be as simple as a backpack sprayer, air-assisted low-volume sprayer, or ultra-low volume sprayers such as foggers.
