Here are THREE SIMPLE RULES we try to always keep in mind when helping you get the best weed control program in soybeans, regardless of trait.
1. USE MULTIPLE, EFFECTIVE MODES OF ACTION
2. FOCUS ON THE WORST WEEDS FIRST.
If you have a million waterhemp plants and 10 velvetleaf plants, for example, I’d probably put 99% of your effort and your dollars toward the waterhemp.
3. SPRAY BOTH PRE-EMERGE AND POST-EMERGE.
This isn’t as important in some other crops, but in soybeans it’s crucial because a number of the best and most effective herbicides in beans can only be used pre-emerge or pre-plant.
DON’T GIVE WEEDS A CHANCE IN YOUR FIELDS!
If you have followed us at all over the last half dozen years, you’ve likely heard the words, “3 Pre’s” 1000 times. I know you want to save money. I do, too. We’ve tried cutting rates, using generics, varying spray timings, and about everything else under the sun to keep our costs down, but I keep coming back to this. In soybeans, if you don’t start with the best pre-emerge herbicides on your toughest weeds, sooner or later you will question your weed control strategy. Soybean weed control is too difficult not to invest a few extra dollars per acre to get a great pre combo instead of a good one.
If you are using XtendFlex or Enlist and you don’t mind investing $20 in Liberty late in the season, you might be able to get by with only two modes of action pre instead of three, BUT IN CONVENTIONAL SOYBEANS YOU ABSOLUTELY NEED THE 3 PRE’S.
