If you’re among the growing number of farmers facing increasing glyphosate resistance, you’re about to be faced with some difficult decisions. In fact, if resistant palmer amaranth, giant ragweed, kochia, waterhemp or marestail are among your list of concerns, planning now for the appropriate seed choice is imperative to maximum return on seed and herbicide investments.
For soybean growers, that means choosing a variety that allows you to use a different mode of action against those weeds showing signs of resistance to glyphosate. Hoegemeyer has a solid lineup of LibertyLink® seeds with varieties that range from a group of 2.3 to 4.9 maturities, so there is a seed for anybody’s acreage. These varieties also yield just as well, if not better, when compared to glyphosate-tolerant soybeans. Many customers who have taken advantage of the LibertyLink lineup have been very satisfied with its performance.
Choosing the right seed now will help your advance planning efforts for early season applications as well. Different from the glyphosate-tolerant soybeans, farmers should make sure to apply a pre-emergent herbicide when planting LibertyLink soybeans. For post-emergent herbicide applications, growers need to get the best spray coverage possible and hit weeds when they’re less than five inches tall.
Great information on confirmed cases of herbicide-resistant weeds in your state can be found through the interactive map provided by the International Survey of Herbicide Resistant Weeds.
