Terraclor 15G is a new, high concentrate in-furrow cotton fungicide developed by Uniroyal Chemical Co., Inc. to replace Terraclor 10G. As a result of the 50% increase in active ingredient, time, labor and space required to handle the product will be significantly reduced with no loss of performance. It has been demonstrated to have excellent physical handling and long-term chemical stability properties. Product efficacy trials indicate that Terraclor 15G has excellent pre and post emergence fungicidal properties. Terraclor 15G has been registered with EPA and will be available for the 1999 cotton production season.
