Herbicide Trait Roulette

October 21, 2010 08:19 AM

IgniteBy now, everyone knows at least one story of a grower that sprayed Ignite on Roundup Ready crops or vice versa. Glufosinate and glyphosate may start with the same letter, but they definitely are not interchangeable.

Still, growers battling herbicide resistance will tell you the trait technologies have their own special strengths. Five years ago, Steve Stevens, a Tillar, Ark., grower decided he’d best integrate some Liberty Link into his all Roundup Ready system before Palmer Amaranth became more aggressive. Instead of an all or nothing swap, he opts to deploy both trait technologies.
Mapping software helps make sure he gets the right herbicide on the right acre. Neighbors have learned to ask what he has planted where. "We have planted the technologies row to row. You can do it," says Stevens.
Last year he planted traits in blocks so aerial herbicide application was still an option. He believes a field flag system would be the ultimate cross check when spray rigs enter the field.
Listen in as Stevens describes how he uses both trait technologies to fight a weed resistance issue that he says "is very real."

   Very interesting. We have been using it for 4 years, 2 in corn & 2 on soybeans. LL Soybeans have only been avaliable in our area for 2 years. Been very satisfied w/ it. We are No-Til people & we need Round-Up to work. We like to use it for burn-down & then use Ignite "Over the Top" to use 2 modes of action in same year. We use some corn hybrids that have both traits which gives us some flexibility. We are also using @ least 50% Conventional Soybeans to add more modes of action to help preserve the ability of Round-Up to work in our No-TIl program. We are actually getting the highest yields in soybeans w/ the conventionals. We are seeing a lot of resistance problems in this area & like He stated, There are a lot of guys in Denial that there is a problem. It is getting more severe every year & in burndown applications it is requiring higher rates of RU a mixture of other chemicals in same application. We do all of our own spraying w/ a SP ground rig.
