A single clean up spray to control insects is generally all that is required to achieve effective control through the harvest period. Make sure to check pre-harvest intervals closely on any pesticides used during the harvest period. Continue to use beating trays every two weeks or so to assist with observations made from harvesting machines. Mite populations can often remain very low during the early summer and then increase rapidly during harvest. Continue to examine leaves for mites and mite predators as well as the bronzing damage spider mite feeding can cause to leaves.
Check fields every ten days to two weeks.
Mite populations can increase more rapidly in drip-irrigated fields and under dusty conditions. Is mite damage restricted to just part of the plant or does it appear to be spreading. Control is usually better if it is timed to catch a building population rather than one that has gotten out of hand. If you apply a miticide, resample about 5 days after the application to determine how effective the spray was. Fruit should be picked frequently where there is much gray mold seen, particularly under wet conditions and in fields with heavy canopies which are slow to dry out.
