Cotton Defoliation

Before we know it, it will be time to defoliate cotton. I attended a defoliation meeting Wednesday where Jared Whitaker, UGA cotton agronomist, spoke about different methods and chemicals used for defoliation. Some methods to determine when to defoliate include looking to see if 60 to 70% of bolls are open(we tend to wait for higher percentage to defoliate), sharp knife method and nodes above cracked boll. Attached are handouts that were given out at the meeting. If you have any questions, feel free to call the office. Also don’t forget we are scraping peanuts for maturity if you would like to take advantage of that service we provide.

Unique Find in Soybean Field

A citizen mentioned to us about how she was having a bad snail problem in her subdivision and how it was only the houses bordering a soybean field. So we went and visited the field and there were snails on the plants. On one leaf we found 3 snails. They were inside the canopy and on the outside foliage. Dr. Roberts, UGA Extension Entomologist, said there is not a good control that is economical for a row crop field and he has never seen them reach the threshold to treat for them.

Peanut Maturity Testing

It won’t be long before peanut harvesting will begin. Our office will be providing peanut hull scraping for any peanut grower. When bringing in a sample, we prefer vines to be brought in along with the peanuts so we can check the health of the vines.  When picking samples, take 5 or 6 adjacent plants from two or three spots in the field.  If the field changes soil types or has some dry land spots, then separate samples should be taken. A sample needs to have between 180-220 pods to show a good representation. Call the office if you have any questions.

Citrus Rust Mites

If you don’t know already, Lowndes County Extension has 2 research trials dealing with satsumas. There are also numerous growers in the county and surrounding counties that have satsumas. Jake Price coordinates and oversees the research trials. A pest to be looking for is the citrus rust mite. Below are pictures of the mite and the damage they cause. This mite can cause damage to the fruit in mid – summer and also in the fall. If you need more information about the mite and how to control it, you can look at the Florida Citrus Pest Management Guide.

Fall vegetable production is underway. I have seen some growers already setting out plants.We have been around the county this week checking fumigant levels.  If you would like your fields checked, give your local extension agent a call.

Scouting Update

Cotton:

Stink bugs are the main pest to be scouting for right now. Also be looking out for spider mites and whiteflies. These insects are important when deciding on an insecticide to spray. A good phone app to help with insecticide choice is the GA Cotton Insect Advisor App. Bacterial blight has been reported in some counties.

Peanuts: 

The main diseases to be looking out for are white mold and peanut rust.

Soybeans:

Below is a guide to soybean scouting that has ways to identify caterpillars in soybeans and also thresholds for foliage and pod feeders.

Please feel free to call the office with any questions.

Time to Sample Pecan Foliage

Now is the time to collect and send off pecan leaves for nutrient analysis. It is recommended to collect the samples from July 7th to August 7th. Below are the instructions on how to sample from the UGA Agricultural and Environmental Services Laboratories. While you are in the field, it may be a good idea to collect a soil sample also if one has not been done recently.

  • 1. Sample trees between July 7th and August 7th. Sampling can be extended into mid August without significantly affecting the results.
  • 2. Take one sample every 10 to 15 acres. If more than one soil type is present in the sampling area and if growth and production varies appreciably in these areas, take one sample from each soil type. Take samples at random using a zig-zag sampling pattern across the grove. When samples are taken annually, the pattern of sampling should be the same; better yet, samples should be taken from the same marked trees or rows.
  • 3. Collect 100 middle pair of leaflets from the middle leaf of this year’s growth.  Use terminal shoots exposed to the sun. Avoid twigs from the interior of the tree. Collect leaflets from all sides of the tree. Avoid leaflets damaged by insects and diseases.
  • 4. Sample trees of different varieties and different ages separately.
  • 5. Abnormal trees or trees not representative of the area should be sampled and sent separately. A complete and accurate description of abnormalities should accompany such samples.
  • 6. Immediately upon collection, wipe leaves (entire surface, both top and bottom) with a damp cellulose sponge or cheesecloth to remove dust and spray residue. Do not allow the leaves to come into contact with rubber or galvanized containers. Partially air dry and place in a large paper bag.
