At this time, Asian Soybean Rust has not been reported in Georgia. However, as with most crop diseases, conditions are favorable for the development of Asian Soybean Rust and when it appears the disease could develop quickly. Of course, our weather patterns will be the driving factor behind the spread and increased risk of this…

During the past ten years, Target Spot in cotton has continued to increase in Georgia. Currently, with warm weather, good canopy growth, and scattered rainfall the conditions are favorable for Target Spot. Of course, when we receive consistent rain showers the cotton experiences better growth and increased periods of leaf wetness which permits the risk…

During this time of the season, (50 to 70 days into season) we are at a critical point in our disease management program. We should continue to maintain our leafspot control programs and implement a good program for prevention of white mold. We have ideal conditions for disease development and activity. Both leafspot and white…

This week we have a decrease in the number of moth captures. Both tobacco budworm and corn earworm numbers are down. However, we should anticipate cyclic (approximately 4 weeks) increases and decreases in these numbers throughout the season. Typically, we will see a pattern develop of a decrease and within 2 weeks another sharp increase.…

Please note in this week’s trap numbers, the significant increase in Corn Earworm (CEW) captures. It is important to remember that Bt cottons are not immune to CEW damage. We should be carefully monitoring blooms, bloom tagged bolls, and small bolls for CEW larvae, that is 1/4 inch or greater in length. Larvae of this…

This week, while evaluating peanuts, I was reminded of a pest that is fairly common but has sporadic activity in peanuts and one we rarely spray for, the Potato Leaf hopper. I wanted to share pictures of hopper burn, a condition that results from leafhopper feeding. It is important that we recognize this damage so…

I am providing this weeks Tobacco Budworm (TBW) and Corn Earworm (CEW) trap captures. Please take note of the rapid increase of moth numbers found in traps. Also, in communicating with Dr. Phillip Roberts (UGA Extension Entomologist), we have learned that beet armyworms (BAW) are active on pigweed escapes in some areas. During scouting cotton,…

I wanted to provide a quick reference chart for common pests in cotton and recommended treatment thresholds. I hope a condensed chart will be useful and save time. Please refer to the Georgia Pest Management Handbook for cotton insecticide options or call our office at 263-4103 or my cell phone @ 305-7047. PEST THRESHOLD Aphid…

Please be aware that there have been several reports of worms in peanuts. The foliage feeders that I have observed were Fall Armyworm caterpillars. The treatment threshold for foliage feeding caterpillars in peanuts is 4-8 larvae/row ft. The low level of four caterpillars/row ft. should be used if the peanuts are small and/or stressed. The…

In the last several years, many growers have experienced great success planting soybeans behind corn silage or traditional corn harvested early. This double crop production system with soybeans has proved to be advantageous in the control of weeds and economically beneficial. The price of soybeans has provided an economic incentive to add an additional crop…
