Abstract
Some planters are using household pyrethrum sprays for Antestia counts. This is NOT recommended. These sprays are not strong enough to give a quick knock-down of all the Antestia. Some of the bugs will remain on the tree and the count will therefore be misleading. Double-strength pyrethrum is essential (2 lb. fresh pyrethrum powder to 1 gallon of kerosene).
