Monitor Spider Mites—Fruit Development
From May through August, monitor for mites at least weekly. If the orchard has problem areas such as trees along roads or water-stressed trees, monitor every few days once mite densities start to increase.
Before July 1, focus monitoring on hot spots, the areas that develop mites first. These are often dusty or water-stressed areas of the orchard. Once the mite threshold has been reached in these areas, sample the remainder of the orchard to determine if a spot treatment is sufficient or if the entire orchard requires treatment.
After July 1, monitor the whole orchard, dividing it into sampling areas that could be treated separately.
