Is Roundup Right for You?

A close look at the herbicide’s ingredients and application methods will help you decide

As a longtime practicing landscape consultant and arborist , I cautiously follow developments regarding pesticide and agricultural products . We are all more interested with the safety of chemical substance these days , and the more we memorize , the more cautious we become . Is Roundup , one of the most commonly used nonselective herbicides , something you want to practice in your cubic yard ? Here are some facts to help you decide .

Know your ingredients

Roundup ’s dynamic constituent , glyphosate , is passably safe if used according to directions . However , the Material Safety Data Sheet ( MSDS ) mentions microscopical cell changes and “ developmental change ” in foetus . Thus , it might be impertinent for anyone design a family to avoid spraying with Roundup .

The other ingredients , which constitute 98 per centum of Roundup , are unfortunately not as dependable . One ingredient is a surfactant ( a substance that helps products stick well on surfaces ) label “ risky ” by the Occupational Safety and Health Administration ( OSHA ) . It ’s a detergent that can get middle , skin , lung , and stomach job , as would any concentrated cleaning detergent you utilize for the floor or dishwasher . So when using Roundup , tire out gloves , do n’t get it in your eyes , and do n’t breathe the sprayer ( I coughed for four week after indiscriminate spraying with Roundup ) .

Glyphosate bandage quickly to grime particles , within two day to two weeks in most compositor’s case . Once in the soil , it does n’t do much . It can prevail for several weeks to six month before territory germ and fungi eventually demean it to phosphate and carbon dioxide .

filth persistency look on many factors , such as weather , territory character , hardiness zona , and premature chemical habit on the land . It can be washed to another place before it tie down , or it can unbind . And its by - products can be in the land for some month . For casual nursing home users , this persistence should n’t really be a concern .

Roundup can run off into piss , however , and is “ moderately toxic ” to some fish . When sprayed , it is “ much non - toxic”—a obscure phrase from the MSDS — to birds , honeybee , and earthworm .

Proper use is crucial

for safely use any herbicide , it ’s important to interpret how it works . Roundup is take up only by actively rise tissue , not barque , so waitress until the leaves number out . The best time to spray is on a calm , dry 24-hour interval between 60 ° F and 85 ° F , when the fart and pelting wo n’t overspread the herbicide where you do n’t want it ( onto other plants ) and when leave-taking are most active .

Roundup is take in in one to two days and then translocate to the roots . It submit one to two hebdomad before the roots decease and the leave loop or wrick brown . Some plants may need two treatments , especially those with shiny leaves , like toxicant common ivy . If you are treating a woody plant , you’re able to cut a bow and then souse the cut airfoil . Spray any leafage that resprouts .

I rarely use chemicals , but when I do , I pronounce the containers they ’re in because then they ’re for good contaminate . If chemical substance are absolutely need to hatch a large surface area , it ’s better to countenance the professional person implement them . And remember that pets , child , and your shoes all convey the chemicals into the house . Studies have shown that the concentration of garden chemical in household carpet , especially near doors , is often higher than allowed outdoors by Occupational Safety and Health Administration .

Since weed come sprout apace , Roundup is only a short - term fix , in effect for spot handling of noxious weed or belligerent plant . The backyard nurseryman should n’t have serious concerns as long as Roundup is used in moderation and according to the label recommendation .

Rely on reputable sources

Good places to regain entropy about Roundup are from toxicant - control centers , government bureau , universities , the manufacturer ( www.roundup.com ) , and the MSDS .

On the Internet , there are some hope scientific sources , mostly from university and governance agencies . However , much of the selective information one line up on the Web is not honest . Most of the sources on Roundup refer to one or two old paper , copied from one vane site to another , rather than from reputable , easy useable scientific journals .
