The Power of RE­AC­TI­VA­TION

Successful Farming - - ADVERTISEMENT -

As un­pre­dictable as weather and weeds can be, their chal­lenge re­mains con­sis­tent. Grow­ers need a prod­uct that can with­stand a va­ri­ety of weather con­di­tions and per­sis­tent weeds. When weather con­di­tions be­come dry, resid­ual con­trol in most her­bi­cides stops work­ing and doesn’t start again, re­sult­ing in ex­tra time and money in­vested to con­trol early sea­son weeds. That’s why grow­ers who want to be tough on weeds rely on re­ac­ti­va­tion.

There is a sci­en­tific dif­fer­ence be­tween resid­ual con­trol and re­ac­ti­va­tion. It just takes a half-inch of rain to ini­ti­ate re­ac­ti­va­tion. Weeds that have emerged will ab­sorb the her­bi­cide with soil mois­ture, and once re­ac­ti­vated, it will go back and con­trol any new weeds that may have emerged. It will also pre­vent new weed growth.

Grower Low­ell Sea­gren of Ri­dott, Ill. un­der­stands the ben­e­fit of re­ac­ti­va­tion. “It's im­por­tant to have re­ac­ti­va­tion be­cause so many her­bi­cides have a short life­time. If you have a prob­lem, it's manda­tory to re-spray which is an­other added cost,“he says.

And Corvus® of­fers just that—re­ac­ti­va­tion.

It is a unique model of her­bi­cide. Whereas con­ven­tional her­bi­cides rely solely on a resid­ual model, Corvus® of­fers burn­down and resid­ual con­trol in ad­di­tion to its re­ac­ti­va­tion fea­ture. With al­most 10 years of proven per­for­mance, Corvus® is the No. 1 pre-emer­gence her­bi­cide brand of choice in the coun­try.

Darin Keller, a grower in Wilber, Ne­braska, ex­plained, “You’ll see lit­tle but­ton weeds and grass come up, and they start to brown in­stantly and turn and go the other way. It’s been a good prod­uct.”

Grower Jerry El­der in Mor­gan­field, Ken­tucky, feels the same way. “Since we’ve been us­ing Corvus®, I have not seen any prob­lem whether we get rain or not. There might be some small weeds com­ing through the field and when it rained then two or three days later, you’d walk out there and they’re gone. So it’s been great. The best chem­i­cal I’ve ever worked with since I’ve been farm­ing,” said El­der.
