THE EXTENSION CONNECTION: Know your herbicide

Published: Wednesday, March 27, 2013 at 15:27 PM.

●Application date and time.

●Trade name, manufacturer, formulation, total amount of product to be applied per acre and amount of the product’s active ingredient applied per acre.

●Total acreage and crop or site treated.

●Average hourly wind speed and direction.

●Nozzle type, including gallons-per-minute rating, at specified pressure — usually 40 psi — and spray emission angle if applicable.

Adjust spray equipment to increase the droplet size coming from the sprayer nozzles. The larger the droplet, the less distance it will travel. Application pressures may not exceed 35 pounds per square inch. You must stop spraying if wind speed is more than 10 miles per hour.

This herbicide rule aims to reduce the risk of herbicide drifting onto someone else’s commercially produced plants, causing irreparable crop damage.
