Weeds, herbicide shortage makes for challenging year


“It’s been quite a summer,” mentioned Weed Specialist Peter Dotray following a subject day on the Texas A&M AgriLife Analysis and Extension Middle, Midway. “It is nice situations for weed progress, a lot of rainfall, a lot of subsequent flushes.

“I think a year like this demonstrated the importance of soil active herbicides.”

Early on within the season, Dotray mentioned it was obvious which fields had a preplant and at-plant herbicide integrated, and “then were starting to overlay their foliar sprays, whether it be a Dicamba or a Liberty or 2-4D that included overlaying with additional residuals.” 

With some areas receiving as a lot as 10 to 12 inches of rainfall all through the top of Might into June and July, Dotray described weed management as “all around the board, the place there are some very clear fields and there are some fields that struggled from the very starting.

“I think some growers really weren’t prepared with all the rainfall and the inputs that were going to be required and they’ve been attempting to play catch up.”

However battling weeds hasn’t been the one problem. A restricted provide of sure merchandise has additional sophisticated weed management. “It’s just really been a challenge,” Dotray mentioned. “A lot of growers first found that Liberty was in short supply, and in a year like this, it has been working very well. Some applications have even been made to larger weeds and they’re still getting pretty good activity, likely because of the humid conditions and succulent growth that the weeds have.”

However quickly that product was briefly provide, as had been different soil residual chemistries, he added. Looking out for particular manufacturers or one thing related took time. “That was costly as far as the timeline of some of the applications.”

Dotray additionally mentioned efficient end-of-season weed management. “For fields that today are relatively clean, the encouragement is that late-emerging weeds are still producing seed and we’ve done studies that indicate a Palmer amaranth plant emerging in August can produce 20,000 seed. So, even though the fields are clean today, as those residuals play out with additional rainfall and irrigation, there could be more weed flushes. We’d like to see some layby treatments applied where those flushes are going  to be controlled before they even come up.”

When Dotray spoke with Farm Press, he was standing in a weed subject trial on the Midway heart. He mentioned this summer season’s situations have made for nice herbicide comparisons. Watch this video to listen to extra of his interview.
