I wanted to provide a quick reference chart for common pests in cotton and recommended treatment thresholds. \u00a0I hope a condensed chart will be useful and save time. \u00a0Please refer to the Georgia Pest Management Handbook for cotton insecticide options or call our office at 263-4103 or my cell phone @ 305-7047.<\/p>\n
PEST<\/strong><\/td>\n| THRESHOLD<\/strong><\/td>\n<\/tr>\n | Aphid (Cotton)<\/td>\n | Apply when aphids are abundant and seedling leaves are severely curled, or when \u201choneydew\u201d is present in older cotton.<\/td>\n<\/tr>\n | Beet Armyworm<\/td>\n | Apply when 10% of squares are damaged, 10% of blooms are infested, or when 10 active \u201chits\u201d are observed per 300 row feet.<\/td>\n<\/tr>\n | Bollworm\/Tobacco Budworm<\/td>\n | Apply insecticide on Bt cotton when 8 larvae (1\/4 inch or greater in length) are found per 100 plantsOn non-Bt cotton apply when 8 small larvae are found per 100 terminals prior to first insecticide treatment, or when 5 larvae are found after first spray.<\/td>\n<\/tr>\n | Cutworm<\/td>\n | Apply when stand is threatened. Spot treatment is often adequate.<\/td>\n<\/tr>\n | Plant Bugs\/Flea Hoppers<\/td>\n | Apply when plants are retaining less than 80% of pinhead squares and numerous plant bugs are observed.<\/td>\n<\/tr>\n | Soybean Looper<\/td>\n | Treatment is necessary when soybean loopers threaten to defoliate cotton with immature bolls.<\/td>\n<\/tr>\n | Spider Mites<\/td>\n | Apply when mites are spreading. Spot treatment may be adequate.<\/td>\n<\/tr>\n | Stink Bugs<\/td>\n | Use a 10-15% boll injury threshold during weeks 3-5 of bloom, 20% during weeks 2 and 6 and 30%(+) during weeks 7(+) of bloom. Detection of 1 stink bug per 6 row feet would also justify treatment.<\/td>\n<\/tr>\n | Thrips<\/td>\n | Apply when 2-3 thrips per plant are counted and immatures are present.<\/td>\n<\/tr>\n | Whitefly (banded winged)<\/td>\n | Apply when 50% of terminals in rapidly growing cotton are infested, or when honeydew is found on foliage or lint of older cotton with open bolls.<\/td>\n<\/tr>\n | Whitefly (silverleaf)<\/td>\n | Silverleaf whitefly is difficult to control with insecticides. Early detection and conservation of natural controls are important.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":" | I wanted to provide a quick reference chart for common pests in cotton and recommended treatment thresholds. \u00a0I hope a condensed chart will be useful and save time. \u00a0Please refer to the Georgia Pest Management Handbook for cotton insecticide options or call our office at 263-4103 or my cell phone @ 305-7047.
