Weeds a widespread problem in Texas croplands


Out-of-control weeds are the newest problem to hit Texas producers among the many adverse results associated to premature rains since late spring, in line with a Texas A&M AgriLife Extension Service knowledgeable.

Wet climate throughout the state has created a convergence of issues associated to weeds for producers of the whole lot from row crops like corn, sorghum and cotton to forages, mentioned Scott Nolte, AgriLife Extension state weed specialist, Bryan-School Station.

“The weather has impacted most every part of the state,” he mentioned. “Many areas have a number of factors that are coming into play when it comes to weeds and weed control. It’s been a challenging season.”

Weeds outcompeting crops

Plantings had been delayed as a result of widespread rainfall occasions that started in late-April. Heavy rains saturated soils in many areas across the state initially, and sporadic rains since have continued to make fieldwork, particularly weed management, troublesome from the Coastal Bend to elements of the Panhandle, Nolte mentioned.

Saturated soil and cloudy days additionally stunted crop progress progress. This delayed the cover improvement that sometimes reduces the quantity of daylight obtainable for weeds to germinate and develop, Nolte mentioned.

Residual preemergent herbicide utility effectiveness degraded over time as nicely, and weeds had been allowed to compete with crops for solar, moisture and vitamins.  

Moisture variability in particular person fields with drier-to-saturated or flooded areas additionally resulted in a lack of uniformity in crop maturation, he mentioned.

Nolte mentioned there have been some cotton fields with a vary of maturity starting from 6-inch-tall crops to crops with blooms as a result of rainfall. The shortage of crop consistency exacerbated maturation points.

There has additionally been an emergence of weeds that had been hardly ever seen in areas of the state in earlier seasons, Nolte mentioned.

“One of the most common calls we’ve been getting is about sedges,” he mentioned. “They thrive in wet environments, and we’re seeing a variety of sedge species in areas we seldomly see them. We’ve had a number of them brought in for identification and control recommendations.”

On the lookout for reduction, rescue from weeds

Producers are additionally in search of management suggestions for fields in want of rescue from weeds, Nolte mentioned. Weeds are simpler to cope with through preemergent functions and by following with sprays that tackle newly emerged immature weeds.

The shortage of well timed functions has many producers in search of suggestions to combat mature grasses and vines, he mentioned. Above-average moisture ranges could permit producers to make use of some choices like Liberty which can be sometimes ineffective below drier situations in areas just like the Texas Plains or Panhandle.

Nonetheless, at the least one prevalent pest plant – pigweed – has producers involved as a result of it has turn into immune to a customary herbicide – glyphosate – in elements of the state, Nolte mentioned. Pigweed is amongst pest crops representing main issues at harvest time as a result of weeds intervene with mechanical harvesting tools.

Nolte mentioned producers conscious of historical past with glyphosate-resistant pigweed produce other choices, however one other challenge has been brief provides of sure merchandise. Numerous worldwide and home provide chain challenge associated to the pandemic and different elements have created conditions the place finding particular herbicides may be troublesome. 

Nolte mentioned there’s additionally concern for cotton producers particularly as a result of the U.S. Environmental Safety Company positioned a laborious cutoff date – July 30 – on using dicamba-based merchandise, Engenia and Xtendimax. Cutoff dates had been sometimes associated to the plant stage, Nolte mentioned, and AgriLife Extension sought an extension for producers in the Texas Plains, however was denied by the company.

Producers are additionally in search of suggestions on tips on how to finest apply herbicides, together with aerial crop-dusting strategies or high-clearance tractors, he mentioned, including that as rain occasions proceed it will be important that producers entry fields to use herbicides earlier than harvest.

“With the cycle of rainfall, you might have two to three days for fields to dry before more rainfall prevents access again,” he mentioned. “So, they’re looking for any way to spray fields so they can harvest as soon as it dries enough.”
