Plant bugs … I’d classify the overall plant bug pressure in cotton as average, although we are seeing a few more clouded plant bugs than in recent years. Until bolls are present, count tarnished and clouded plant bugs the same. Once bolls are present, I suggest counting clouded plant bugs as equivalent to 1.5 tarnished plant bugs when making a treatment decision, primarily because clouded plant bugs are more inclined to feed on bolls. As cotton begins blooming, Continue reading

Tennessee Weather and Crop Progress Report
RAIN DELAYS CROP HARVEST, PLANTING; IMPROVES CROP CONDITIONS
The rain shortened week delayed the end of winter wheat harvest and thus double-crop soybean planting. Tobacco and hemp producers made some headway on setting their crops between rains. Limited field activities included applications of weed controls and nitrogen, and 2nd cuttings of hay. The persistent rains are positively affecting crops and pastures and heading off heat stress. Vegetables in the eastern part of the state have little to no insect pressure. There were 4.5 days suitable for field work. Topsoil moisture was rated 8 percent short, 73 percent adequate, and 19 percent surplus. Subsoil moisture was rated 11 percent short, 75 percent adequate, and 14 percent surplus. Hay and roughage supplies were rated 4 percent very short, 15 percent short, 69 percent adequate, and 12 percent surplus. You can continue reading the entire report here: TN Crop Weather 07_01_19.

Managing Early Season Plant Bugs in Cotton
Good early-season management of tarnished plant bugs relies on a sweep net, monitoring square retention, and making timely insecticide applications as needed. During the first two weeks of squaring, the recommended treatment threshold is an average of 8 or more plant bugs per 100 sweeps. After that, treatment is recommended anytime of infestations average 15 or more plant bugs per 100 sweeps Continue reading
