Current Crop and Pest Situation
I am somewhat encouraged by the way many acres of crops have grown off here in July. And as I write this newsletter we have a decent chance of rain this weekend through the first of next week. July temperatures have been almost ideal in terms of heat units. It would be answer to prayer to have some nice gentle rains line up in August and September.
I will start with grain sorghum and corn since it is relatively easy to summarize right now. No sugarcane aphids have been found on grain sorghum in Lamb, Hockley or Cochran Counties this season to date. We are seeing a few grasshoppers along field margins.
In young whorl stage corn and milo am starting to see some worm feeding, but nothing alarming or treatable. I would encourage producers to be monitoring late planted grain on a regular basis from here on out. Call if questions.
Peanuts are doing very well. So far an excellent pod set has been noted in all scouting fields. Larvae feeding on foliage were noted this week, but very light. Leaf spot, pepper spot, and limb rot were noted this week.
With the age of the peanuts, weather pattern and irrigation frequency a preventative fungicide would be highly recommended. Weeds continue to be challenging. 2,4D-B with some residual like Dual has been common choices. Please call if questions.
Herbicide Resistance Info
Cotton ranges from 1/3 grown square (not yet blooming) to 4 nodes above white flower (in physiological cut out). My ideal plant right now would have 1st position bolls developing at nodes 7-10, with a white flower at node 11, and then 6 nodes above white flower.
This plant will reach physiological cutout the first week of August and be blooming out the top the third week of August. This takes full advantage of the growing season while allowing time for maturing this fruit to contribute to quantity and quality.
The scouts and I are hard pressed to find much in the way of cotton pests right now. Keep scouting though for insects and checking that cotton for progress.
My priorities this next week are:
- Keep up with crop water demands, we are at or near peak use in flowering cotton, all peanuts and flowering grain.
- Wrap up all fertilizing, with exception of some light fertilizer in irrigation water and late milo.
- Keep close watch on aphids, Lygus, cotton bollworms/headworms over next few weeks; and especially sugarcane aphids. Give me a call if you find them.
- Maintain our good square set going into flowering on late cotton and maintain a good boll set with limited damage and losses.
- Be proactive on peanut diseases.
Also, here is a video which will help explain the importance and the “how to” of determining nodes above white flower in cotton. This is a critical measurement for many management decisions in cotton.
