Posted on by

We have found a few corn leafhoppers in Victoria corn fields.  These have been much more difficult to find than last year. I suggest you listen to the update below to learn how Dr Kerns is finding them in corn fields in the Brazos valley. Most of the corn in the mid-coast is in dent stage and well past the damage window of the corn stunt disease transmitted by the insect.

IPM Update 6/6/25

  Refugio County Crop tours are Wednesday.  Check here for more info on Crop Tours. Audio Updates are another way to get IPM Updates. Find them here. We have found little change in the field over the past week. Crops continue to progress and fleahoppers and stink bugs are the primary things to look for in cotton, sorghum and soybeans. Southern Rust is the issue of greatest concern in corn fields of the Mid Coast of Texas.  Many fields have southern rust pustules on the leaves of the… Read More →

Corn Update 5-30-25

I received a call early Tuesday about a Victoria county corn field with purple/red leaves below the ear.

Other options include nutrient deficiency. The… Read More →

Cotton IPM Update 5-30-25

Cotton Maturity ranges from squaring to bloom.  We are still finding fleahoppers in some fields. In fact our insecticide test had mostly of adult cotton fleahoppers and some Verde Plant bugs this morning before the rain.  The treated plots had very few nymphs but the untreated cotton had adults and nymphs at a 1:1 ratio. We are seeing control with all of the products at 7 days after treatment, but the nymph counts for Bidrin was was not different from the untreated nymph counts. Once you find 1… Read More →
