In trees 5- to 9-feet tall, it takes about 30 days before you’ll see consistent control, and it will last for another approximately 30 days, Rogers says.
For the smaller trees, he recommends more, but smaller, applications. In the larger trees, he recommends one application at maximum labeled rate of Admire or Platinum or two applications with half labeled rate of Belay.
Regardless of the tree size, Rogers says growers should fill in the control gaps with foliar insecticide applications with different modes of action than neonicotinoids.
