Recent flooding in east Arkansas' St. Francis County.
With yet another round of mid-July rains headed towards the Delta, Bob Scott says there are some options producers might consider.
“Right now, there are a lot of flooded acres that farmers are looking to replant,” says the Arkansas weed specialist. “There are also a lot of wheat beans being planted.
“When you get this late in the year, late June/early July, you start running into plant-back interval problems. Some of the residual herbicides like Flexstar and Dual are essential to fighting pigweed in Roundup Ready crops.”
Unfortunately, for a number of reasons, there is still reluctance among some growers to switch to LibertyLink technology. However, says Scott, “it really does have a much better fit in situations where we get to the point where we can’t, or shouldn’t, use products like Flexstar and Dual which could potentially carryover to next year’s crop.”
Some of that reluctance is tied to the cost of the LibertyLink system. “In some areas, growers have said it’s worth the cost and they’re heavily utilizing the technology.
“Another thing is Monsanto still has a big pull and influence on many folks’ decision making. That’s true from the grower to the seed salesman to the chemical salesman. Monsanto has done a great job, by the way, with their rewards program where growers are paid to use residuals. That has been tremendously successful.”
The LibertyLink technology has now been available for a number of years. “The bottom line is we probably wouldn’t be growing cotton if it weren’t for Phytogen and LibertyLink varieties. Those enable farmers to deal with pigweeds because they’re tolerant to Liberty. Unfortunately, we just don’t have the tools to control pigweed any longer in Roundup Ready cotton.
“Another aspect of this is many of our LibertyLink soybeans are being planted on the absolute worst pigweed fields that growers have. If they aren’t using a residual in those fields, if they aren’t making an early application of Liberty, then this one technology is kind of being abused. That’s all we have left that’s very effective on pigweed with no crop rotation issues.”
