Use New Neem Product for Grub Control
Neem is derived from the seeds of an evergreen tree, Azadirachta indica, native to India. Neem oil has been available in this country for about 20 years, but the patented water-soluble innovation is relatively new.
Since the white powder is water soluble, it’s far easier to apply than the oil. A hose-end sprayer works well for lawns or trees and shrubs.
The product is labeled for hundreds of insects including the larval phase of beetles known most commonly as grubs. We spoke with the scientific advisors of Azasol yesterday and their best advice was to apply the product now in the temperate regions of the country where grass is actively growing. That will cause the product to be readily absorbed by the stems, leaves and roots of the grass plants so that if or when the grubs eat the grass, they’ll eventually die.
If you know you have a significant grub problem in your lawn, a second application of the product — at rates described on the label — is recommended about three weeks later.
It’s important to note that neem is not a “contact” killer. And unlike imidacloprid or clothianidin, the active ingredients in most synthetic chemical grub-control products, neem causes the grubs to stop feeding and breeding. In other words, if you spray the Azasol directly onto the grub, the insect isn’t going to fall over and die immediately — but that doesn’t mean the product isn’t working.
Additional scientific trials are underway this season so that we and the world at large can gain more personal information about Azasol and they way it works on various turf insects. In the meantime, any lawn companies or homeowners who would like to try the product can contact Azasol directly at www.azasol.com.
