Injury Symptoms

There are several causes for some plant symptoms in addition to herbicide drift. Among them are insect damage, fungal and bacterial diseases, and environmental conditions. It is usually not legitimate to assume pesticide drift has caused a symptom based solely on the appearance of a plant. Other factors such as alternate causes of symptoms, locations of recent applications, type of herbicides used, weather conditions during and after the application, and damage patterns in neighboring areas all must be considered. Keep this in mind as you browse these sites.
