Its been 2 weeks since we made our last scab spray. Since that time its been hot and humid. Pecans are entering the period of rapid nut enlargement--a period when nuts are most susceptible to scab infection. So between rain storms, we decided to start our second scab spray for the year (photo at right).
We are using a systemic fungicide (Quilt Xcel) so, as long as we get 6 hours of drying time before the next rain, the fungicide should be effective.
