1. Correct Timing— Proper timing of spray applications is essential to control diseases and insects, Scab and other diseases are more severe following rainy weather and may rapidly reach damaging levels if young foliage and developing nuts are not protected by properly timed fungicide applications. Apply fungicides before infection occurs. Apply the first spray just as the new leaves begin to unfold; follow with the second spray 14 days later. These two sprays are the most important because this is the most susceptible stage for leaf infection by the scab fungus, as well as several other fungi that cause leaf disease. Follow with fungicide spray applications every 14 to 21 days. You may need to spray more frequently In extremely wet weather. Insect control sprays are not necessarily required in each scheduled fungicide application.

2. Complete Coverage—Complete coverage of leaves, twigs, and nuts of pecan trees for disease and insect control is necessary. The spray equipment must be capable of delivering the pesticide to the top of the highest trees. Mist Blowers will spray up to 85 feet high and will all you to spray the tree from top to bottom. When using a Mist Sprayer, use recommended application rates. Poor coverage can cause severe disease and insect damage.

3. Application Rates—It is essential that you use adequate application rates.
