Texas: Lower Rio Grande Cotton – Mostly Quiet but Keep Watch for Fleahoppers

Cotton is maturing and blooming nicely. Not seeing a whole lot going on in cotton this week. We are picking up on some fleahoppers in cotton throughout the Valley. Went out to Raymondville and Sebastian and was picking up an average of 12 to 15% infestation of fleahoppers.

As I moved closer to the coast the infestation level increased to about 30% but on average in Willacy and in Cameron county we are seeing anywhere from about 10% to 30% fleahoppers. We are seeing both adults and nymphs so treat fields accordingly.

We are picking up on whitefly adults as well in cotton throughout, but I noticed down by the river in the Donna area I was seeing more whiteflies under the leaves but still nothing that warranted spray yet.

I was not seeing many aphids at all, very little if any and lots of predators in the cotton feeding.

I would like everyone to be aware that we did receive approval for a Section 18 for use of Transform in cotton for control of plant bugs; this section 18 expires October 31, 2017. The Section 18 label for Transform in cotton is attached. When using Transform to control plant bugs a rate per application allows for 1.5-2.25 oz/acre, with no more than a total of 8.5 oz/acre per year to be used.

Remember to Not apply within 14 days of harvest and do not make applications less than 5 days apart. Also do not make more than two consecutive applications per crop.
