Cold Temperature and Herbicide Storage
Chuck Bornt, Team Leader, Extension Vegetable Specialist
Eastern New York Commercial Horticulture
Cold temperatures can affect herbicide performance; applications of postemergence products under cool conditions may result in delays in symptom development and some treatments may fail altogether. Cold temperatures are also a concern for stored herbicides, particularly liquid products. Freezing (which may occur at temperatures below 32 F for some formulated products) can result in the active ingredient settling out of solution. Some, but not all, labels will provide advice regarding resuspension. If in doubt, call your pesticide dealer or the product manufacturer to determine if the herbicide contents can be re-dissolved and used, safely and effectively.

We will then discuss the treatments in our field trial, discuss results to date, and get initial reactions from the grower, while viewing the field trial. We will then discuss the other study objective, using a mechanical weeding system to replace contact herbicide applications, currently underway in the Champlain Valley.
