How much of this product (per gallon of water) should I use in my 2-gallon sprayer to control pine tip moths on my Pinon pines and Austrian pines? And if I apply it as a soil drench rather than direct spray to treat those same pine tip moths, what should that concentration be (amount per gallon of water, or per inch of trunk diameter, etc.)? Thank you for your help.
Acephate 75UP Insecticide can be used on ornamental trees and shrubs to control Nantucket Pine Tip Moth Larvae. Per page 19 of the product label, apply .75 lb (12 oz.) per 100 gallons of water as a full coverage spray at 14 day intervals as necessary to maintain control. Do not apply more often than 3 times in a growing season to trees and shrubs. This rate would be roughly 0.27 oz. per 1,000 square feet in at least 2 gallons of water. Acephate 75UP does not have labeling for soil drench for pine tip moth larvae, however we do sell other products that are. Adonis 2F would be a great choice for soil drench for this pest in Spring. You will use Adonis 2F at a rate of 0.1 - 0.2 oz. per inch of trunk diameter at breast height for soil drench. You should use no less than 10 gallons of water per 1,000 square feet when drenching, apply directly to the root area, and remove plastic or any other barrier that would stop the solution from reaching the root zone. For either application, it is recommend to speak to your local County Cooperative Extension office for recommendations on the best timing to treat for this pest in your area.
