Here are some comments from Dr. Eric Prostko, Extension Weed Specialist, about the combination of Warrant and Valor for pre-emerge weed control in peanut: “As I sit in my office watching yet another rain event (April 29), I am wondering why most GA growers seem to have a passion/obsession for using…
Yesterday I got out and drove around the county. I noticed many farmers working hard to prep land for planting peanuts and cotton before the rain forecasted for the rest of this week!
By Monday many fields were dry enough to keep tractors standing in the field and move the soil. For the past seven days soil temperature has averaged in the mid to upper 70s above the recommended 68 degree temperature for planting. Temperatures will drop in the next few days, but I don’t see that being an issue. The low for the week, according to the National Weather Service, will be around 51-52 degrees. After this Friday we are projected to have warm weather, so this should help with germination and drying the soil. Unfortunately all this heavy rain could wash out newly planted fields and will of course further delay planting of other fields in peanuts and cotton.
We need the rain to hold up. Wet cool conditions could slow down germination and seedling disease is always a concern. Make sure you included a seed treatment if it’s not already there. Also, consider the use of an in-furrow or banded application (3-5 wks after planting) of Proline or Abound for the control of seedling diseases.
Recently I received a call from a grower about the fungicide spray schedule for his melons. He was concerned about higher fungal disease pressure based on the weather for the past two weeks. His concern was valid considering fungal diseases do well in cool wet conditions!
According to Dr. Langston, extension vegetable pathologist, fungal and ‘fungal like’ diseases are more of an issue later in the season than now. But, bacterial spot, caused by Pseudomonas spp., can be a issue this time of year. Especially with the conditions we have had recently.
Today, April 23rd, bacterial leaf spot was found on watermelon and cantaloupe. Both cases warranted an application of copper fungicide.
Dr. Langston says:
“We are seeing Pseudomonas leaf spot on cucurbits again this year, especially after the cool, wet weekend we just had. The spots can appear dark and greasy at first, then they turn light tan in the center and you can see a concentric ring pattern in the lesion. Usually the weather turns this disease around as warm (80o F+) dry conditions are unfavorable for the bacterium.”
If you’re concerned about bacterial spot on your vegetables apply a low rate of copper fungicide along with the fungicides recommended in the spray schedule. Do not use a high rate given that melons, especially cantaloupes, may be sensitive.

Year after year pecan scab maintains the most costly disease in pecan production in the state of Georgia. Currently UGA’s fungicide programs are centered around scab management and changed if other diseases become an issue. The scab pathogen infects both the foliage and fruit, so season long protection is a must. This calls for a…
As we are starting a new growing season proper disease management is a must. Potential diseases and nematodes should be managed early to insure a good start to our corn, peanut, soybean, and cotton crops. Here is an exert from the UGA Extension Pathologist, Dr. Kemerait: The 2014 field season is upon…
