GENERAL SITUATION

Soil conditions will vary from adequate to wet. The majority of the corn and grain sorghum is making good progress with the exception of areas with excessive moisture. Corn will range in size from 6 inches to close to tasseling (Aquilla area). Grain sorghum will vary from just coming up to boot. Cotton growth stage will range from just planted to 6 true leaves.

CORN and GRAIN SORGHUM

Greenbugs are being seen in light numbers in grain sorghum.

Yellow sugarcane aphids have not been seen in area fields.

Corn leaf aphids are in light to medium numbers in the whorls of milo. This insect does not inject a toxin into the plant and is also a good source of food for beneficial insects.

COTTON

Producers should continue to monitor any late planted cotton in weedier conditions for cutworms.

Thrips numbers and damage will vary from light to moderate. We are seeing some fields with damage to the newer leaves. Numbers appear to be increasing over the last several days.

Cotton aphids are in light numbers with a slight increase in a few area fields.

Fleahopper numbers will range from 0-10 per 100 plants.

Grasshoppers have been seen in area pastures over the past month.

Overwintered boll weevil trap counts are in light numbers.

***********************************************

Producers with Roundup-Ready cotton should monitor their fields closely for plant growth stage and time the Roundup application prior to the 5th true leaf reaching the size of a quarter. Farmers should anticipate adverse weather (wind or rainfall) and apply this application early enough to insure plants have not exceeded the recommended size.

Warmer temperatures have accelerated plant growth. Cotton is growing-off quicker than expected.
