Howdy,
We are harvesting cotton, and I am happy to see module trucks rolling and gins running.
The 6 and 11 days after treatment (DAT) ratings for the cotton harvest aid study for Wharton, Texas are below. The initial treatment was made on August 20, and the second on September 2, 2021. The cotton harvest aid study for this site was conducted on a field of Phytogen 332 planted on March 21, 2021. If you are having trouble viewing the results, a larger version can be found here.

| Spraying the 2021 Defoliation Test Kate Crumley |
Howdy,
I've included the 6 days after treatment (DAT) ratings for the cotton harvest aid study that was treated on August 20, 2021 in Wharton, Texas. The test plot is located at (29.292813, -96.168313), off CR 961 near the Wharton fairgrounds, if you would like to stop by. Ratings for 6 DAT were taken on August 26, 2021, prior to the second treatment. Ratings will be taken again at 12 days after the initial treatment. The cotton harvest aid study for this site was conducted on a field of Phytogen 332 W3FE. There is a printable version of this table available at our county website. As always, if you have any questions, feel free to send an email or give me a call if you have any questions or concerns.2021 Cotton Harvest Aid Trial- Wharton County

Howdy,
Our season is rapidly wrapping up, most of the grain is out of the field, and I've seen some soybeans harvested. We've started defoliating and picking cotton as well.

Howdy,
Our season is rapidly wrapping up, most of the grain is out of the field, and I've seen some soybeans harvested this week as well.
Most of our cotton is opening up, and even our latest fields should be opening next week. We are a good ways past cutout, and past susceptibility to any insect damage in almost all locations. There are very few fields still susceptible to stink bug damage. I've seen a couple fields defoliated this week, and next week I expect to see a good deal more ready for defoliation.
Defoliation is usually recommended at over 60% open bolls, or 4 nodes above cracked boll. For more information, here are links to a defoliation guide from the Texas Row Crop Newsletter, the 2019 Mid South Defoliation Guide, and the Wharton county defoliation test results from 2017.
Cutout occurs when carbohydrate supply equals demand, and vegetative growth ceases. When the plant reaches cutout, no more harvestable fruit is set. This is normally at 4 to 5 NAWF. Cotton is no longer susceptible to economic damage by plant bugs and bollworms at 350 degree days (DD60), or heat units, past cutout, and is no longer susceptible to economic damage from stink bugs at 450 DD60 past cutout. Bolls that will reach maturity by harvest will be too hard for the respective pests to feed on at this stage.
The fields I check are no longer at risk for damage from bollworms and stink bugs. If we are finding any plant bugs, they're mostly brown and green stink bugs, some leaf-footed bugs, lygus bugs, and tarnished plant bugs. These are all below threshold, or like most of our fields, in places that are no longer susceptible to damage.

Howdy,
Our grain crops are mostly out of the field. There are spots we've been delayed by rain, but for the most part we are wrapping up grain harvest. Sorghum yields have mostly been poor due to sprouting and the wet conditions we had earlier, but our corn yields have mostly been fair to good.
This week most of our cotton is opening up, and even our latest fields should be opening next week. We are a good ways past cutout, and past susceptibility to any insect damage in almost all locations. There are very few fields still susceptible to stink bug damage. We will start defoliation next week.
Defoliation is usually recommended at over 60% open bolls, or 4 nodes above cracked boll. For more information, here are links to a defoliation guide from the Texas Row Crop Newsletter, the 2019 Mid South Defoliation Guide, and the Wharton county defoliation test results from 2017.

Howdy,
Our grain crops are mostly out of the field. There are spots we've been delayed by rain, but for the most part combines are running and we are getting corn and sorghum out of the field. Sorghum yields have mostly been poor due to sprouting and the wet conditions we had earlier, but our corn yields have mostly been fair to good.
This week most of our cotton is starting to crack, bloomed out, or around 2-5 nodes above white flower (NAWF), and our later replanted cotton is at or just past cutout. Cutout occurs when carbohydrate supply equals demand, and vegetative growth ceases. When the plant reaches cutout, no more harvestable fruit is set. This is normally at 4 to 5 NAWF. I've included heat unit charts below to help with spray decisions for our insect pests our fields reach cutout. Temperature data for each county location is based on a field close to the center of each county. Cotton is no longer susceptible to economic damage by plant bugs and bollworms at 350 degree days (DD60), or heat units, past cutout, and is no longer susceptible to economic damage from stink bugs at 450 DD60 past cutout. Bolls that will reach maturity by harvest will be too hard for the respective pests to feed on at this stage.
The fields I check are almost all out of risk of damage by bollworms and stink bugs, we have one still susceptible to bollworms, and two to stink bugs. We're still mostly seeing brown stink bugs if we find any, but we are seeing some green stink bugs, leaf-footed bugs, lygus bugs, and tarnished plant bugs, all below threshold or in places that are no longer susceptible to damage. This week's scouting results are below. Fields marked in black are no longer susceptible to damage from that pest.

Howdy,
This week most of our cotton is starting to crack, bloomed out, or around 2-5 nodes above white flower (NAWF), and our later replanted cotton is blooming. We are at and past cutout in most places, other than the later replanted cotton. Cutout occurs when carbohydrate supply equals demand, and vegetative growth ceases. When the plant reaches cutout, no more harvestable fruit is set. This is normally at 4 to 5 NAWF. I've included heat unit charts below to help with spray decisions for our insect pests our fields reach cutout. Temperature data for each county location is based on a field close to the center of each county. Cotton is no longer susceptible to economic damage by plant bugs and bollworms at 350 degree days (DD60), or heat units, past cutout, and is no longer susceptible to economic damage from stink bugs at 450 DD60 past cutout. Bolls that will reach maturity by harvest will be too hard for the respective pests to feed on at this stage.
We are still checking for stink bugs in a few of our cotton fields, and for bollworms in fewer. The stink bug pressure is very low, but present. Most of our fields have been treated in the last two weeks, and most of them are no longer susceptible to damage. None of the fields we looked at were over threshold, but several of them were sprayed last week. I've heard about other fields in the area above the economic threshold from other consultants. We've mostly seen brown stink bugs, but we are seeing more green stink bugs, leaf-footed bugs, lygus bugs, and tarnished plant bugs below threshold. This week's scouting results are below. Fields marked in black are no longer susceptible to damage from that pest.
