Remember that the pesticide label is a legal document. Those who apply or use the products need to read the label. Changes are often made to pesticide labels, and often those changes are not well publicized. Also, not all labels with the same active ingredients have the same wording. So read the label for the specific product you intend to use. Use rates and use restrictions can vary with geography, so information you get off the internet may not be accurate for your farm. You will only know that if you read the label. UD Extension does a great job of highlighting specific points that are on labels, but we might miss a specific point that pertains to your situation. So read the label.
