Free Shipping on All Orders

Merit 75 WP is a wettable powder that provides the industry's longest-lasting grub control at exceptionally low use rates. This product gives outstanding residual control of numerous ornamental pests - it interferes with nerve impulses and disrupts insect behavior. Pests stop feeding, stop reproducing and eventually die.

How frequency should I apply Merit 75 WP in Hawaii for plumeria?
Dan D on May 19, 2018
BEST ANSWER: Make foliar applications as pests begin to build before populations become extreme. Two applications at a 10 to
14 day interval may be required to achieve control. Scout and retreat if needed.
Thorough uniform coverage of foliage is necessary for optimal control. Addition of an organosilicone-based
spray adjuvant at a rate not to exceed the adjuvant manufacturer's recommended use rate may improve coverage.

We recommend you refer to the Merit Label for exact application recommendations.

Merit works!
Thought this did exactly what it should have with my grubs, see you later! I did check to see when I should apply, that is a little confusing.
September 5, 2017
Mixes well, and has a residual life. can spray on bushes and trees and even roses. Bugs are gone! But like I have said before, you must keep spraying, not everyday....but, don't just spray once and call it good. set up a schedule and spray! Our chemicals don't last as long as they did in the 60's and 70's, but they still do well if you use them properly.
