Harvest Aid Test

A cotton Defoliation Demo was sprayed last Monday (8/23) with a second application made Today (8/30). The demo is located in Victoria County on Kainer Rd. Just north of Raven Rd. Drop by and take a look when you get the chance. Treatments are as follows:

Cotton Near Cutout

Much of our cotton fields are at or near cutout.  The fields we have been in this week range from 2-6 nodes above white flower (NAWF).  Keep in mind the time for a white bloom to  mature into an open boll is around 50 days. We are finding bollworms in non-Bt and 2-gene Bt cotton such as Bollgard 2 and Twin-Link cotton varieties.  I have not found much damage or worms in the 3-gene cotton varieties containing the VIP gene. Treat cotton fields when square and boll damage… Read More →

Rain and Square Loss

Scouting fields this week we are finding each field is different from the next. Much of this has to do with how the rain affected the field. If the water got off the field or did not stand for too many days, the crop was better off. Fields that held water are more likely to have square losses. Many of these fields have lost the larger squares leaving fruit smaller than match-head square. An example of this is shown. I removed the leaves showing the lower four squares have… Read More →

The table below shows how many days are usually required to get from one stage to another. Notice emergence to first square usually takes 27 to 38 days. The difference between these is how warm or cold temperatures are. SOURCE I planted a cotton variety trial in Austwell, TX on March 12, or 47 days ago. Today this test is at 6-7 true leaf and I am finding… Read More →
