              Which Brands Make The Best Herbicide For Nutsedge?

              Spectracide

              This brand belongs to Spectrum Holding Inc. While the company focuses on producing and selling products that can serve indoor and outdoor living, the Spectracide brand manufactures pesticides and herbicides which target lawn fungus, pests, and weeds.

              The Washington Toxics Coalition said that their products can be harmful to humans. However, wearing a pair of protective gloves and glasses can keep you from irritating your skin and eyes because of the low-to-moderate level toxicity rating.

              Roundup

              This is one of the most famous brands in the herbicide and pesticide industry all over the world because they are good at applying agriculture biotechnology and agrochemicals.

              The World Health Organisation determined that this brand is bad in 2015 since their products probably cause cancer, but conflicting scientific studies show that the key ingredient in their products - glyphosate has a low risk. To damage DNA, causing tumors, it requires high exposure.

              FAQs

              Does using herbicide for nutsedge make it worse?

              No. For example, post-emergent herbicides can prevent the infestation of existing nutsedge, but they require you to apply on the right time - before tubers mature when it is in mid to late summer.
