Texas LRGV Cotton: Whiteflies on the Rise, Plant Bugs Present

    Incredibly hot down here in the Lower Rio Grande Valley so stay hydrated as you work your fields and monitor your crops. Temperatures have been reaching 100oF a few times but on average we have been having temperatures in the high 90s but really doesn’t matter when the heat index makes it feel like its 110oF.

    We did receive some good rain this week across the Valley with mostly everyone getting at least 1.2 to 1.5 inches but some spots received quite a bit more. Either way it was enough to get rained out and so next week should be a busier week trying to get in and harvest or spray in some areas as needed.

    Muddy this week getting into a lot of you all’s cotton fields as many had been just irrigated when we received this much needed rains. Across the whole Valley I am definitely seeing an increase in whiteflies, in both adults and in nymphs.

    Some cotton fields have already had to be sprayed around the Santa Rosa area to control whiteflies and I know in Mexico they have been having some issues with high whitefly populations in the cotton as well.

    Also we have been seeing about 2-3 tarnished plantbugs, 1-2 Verde bugs, and 1-2 stinkbugs per 100 sweeps in generally all cotton fields across the Valley. So plantbugs are present.

    We have a lot of mature bolls but still have a lot of immature bolls out there and lots of later planted cotton. We are seeing many predators in the cotton as well, lots of minute pirate bugs, lacewings, lots of lady beetles, schymnes beetles, and big eyed bugs which is always very helpful and good to see present.
