According to the latest West Plains IPM Update from Texas A&M AgriLife, crop conditions across the western South Plains are continuing to progress, with cotton development moving closer toward bloom.
The July 2 report by Extension Agent Kerry Siders states that cotton ranges from three to 11 total nodes, with square set reported at over 80 percent. Siders noted that the most first-position squares observed was five, with the average firstfruiting position at node seven. Siders explained that cotton typically reaches bloom with eight nodes above white flower, meaning fields currently at five first-position squares will need to develop about four more before blooming. Based on current conditions, Siders estimates that the most advanced fields could reach first bloom around July 14, while much of the crop will not bloom until after July 20 to 25.
The report noted that fields are starting to pick up quite a few cotton fleahoppers and isolated colonies of cotton aphids across the region. Siders said that one of the main questions he gets is what products people should use to manage them. He recommends waiting a bit longer for cotton aphids, noting that with all the rain, the problem might take care of itself. Siders said that many products used to treat cotton fleahoppers are also effective against cotton aphids, citing Transform WG, Centric 40WG, and Carbine 50WG as examples, and added that Transform is the best option for cotton aphids.
Peanuts are currently blooming, with pegging just beginning and pod set expected soon. Siders said the crop is about 10 days behind normal, adding that irrigation is critical at this stage to support plant growth and create conditions favorable for peg penetration into the soil. He added that hot, dry soil conditions can limit proper peg development and reduce pod formation, though little disease pressure has been observed so far.
In grain sorghum, Siders reported minimal insect issues, with most concerns centered on weed control. However, he said, with the large number of late-planted acres this year, there could be increased risk of midge and grain sorghum aphid problems later in the season.
The report also said corn leafhoppers remain low in eastern Hockley County, with no visual symptoms of red stunt disease reported at this time.
