Crop Scouting Field Meeting – June 27
Monday, June 20, 8:30 a.m. Location: Calhoun County, Cotton field at corner of Hwy 87 and FM 2433. Topics: Scouting Cotton and Sorghum
Mid Coast Grain Sorghum Update
Grain Sorghum maturity ranges from milk to near harvest. Some fields may have already been harvested. The primary insect pests in post bloom sorghum is stink bugs, headworms and aphids. Stink bugs and headworms can cause economic losses until hard dough. Once the seed is at hard dough, these pests are no longer an issue. The economic threshold for headworms ranges from 0.15 to 1 large worm (> 0.5 inch) per head. For medium worms (0.25-0.5 inch) the ET ranges 0.8 to 2 per head. The threshold for… Read More →
Mid Coast Cotton Update
Cotton maturity spans the gamut. Field maturity ranges from 1/3 grown square to near cutout. Monitoring for stink bug and Verde plant bug is important in cotton fields in bloom. We have not found a field with economic populations of stink bugs yet. Most fields have less than 10% evidence of feeding and many are 1-3%. The economic threshold for stink bugs is 20% evidence of internal feeding. Treat for verde plant bugs when finding more than 20-25 bugs per 100 plants. Up the coast, I have received… Read More →

Mid-Coast Grain Sorghum IPM Update
Grain sorghum in the Mid-Coast of Texas ranges from Milk to hard dough. Harvest is just around the corner for some fields. This was noticeable by seeing combines and headers out of the barns getting ready for use. We are finding light numbers of stink bugs and headworms in fields across the mid-coast. Continue to check fields weekly for these pests. One question asked of me this past week involved how to manage stink bugs or headworms in fields with light sugarcane aphids. My suggestion is not to… Read More →
