10 Best Granular Weed killer 2022 – Reviews & Guide

The granular weedkiller is a product that can be used by both professionals and homeowners to get rid of weeds in the lawn. It is made up of different ingredients, including water, sand, and fertilizer.

There are several benefits that this product has to offer. If you want to use it for your lawn, you need to know how to apply it properly so that you can achieve optimal results.

How does Granular Weed killer work?

It is a pre-emergent herbicide that controls crabgrass and other grassy weeds in the spring before they seed out. It contains the active ingredient dithiopyr, which stops crabgrass seeds from germinating but not at the roots of existing plants or weeds.

You can use this product as early as January or February (depending on your climate zone) before any signs of crabgrass appear on your lawn. The best time to apply this product would be when temperatures reach 50 degrees F or higher during daylight hours for three consecutive days after application.

The Scotts Company is an American worldwide manufacturer and marketer of branded consumer products for lawn and garden, pest control and outdoor recreational use.

The company’s brands include Scotts, Miracle-Gro, Tomcat, Ortho, Roundup, Osmocote, Home Defense, Roundup and the Zerotol fungicide.

The Scotts Company was founded in 1868 by Orlando McLean Scott in Marysville, Ohio. In 1970, the U.S. government charged that the Scotts Company and other leading companies had engaged in price-fixing activities; in 1981, it pleaded guilty and paid a $150,000 fine. The company has been criticized for its use of greenwashing advertising to promote its products.

In 1998, A.C. Prorok & Associates Inc., a small company based in Santa Rosa Beach, Florida sued Scotts for patent infringement because of the invention of “slow-release” fertilizer pellets developed by Prorok and used in Scotts’ Osmocote product line. In 2005, the United States Court of Appeals for the Federal Circuit upheld a jury’s $17 million verdict against Scotts for infringing on Prorok’s patent rights. Before this decision was handed down, Prorok had been awarded.
