Popis: | Union Carbide UC-21149, 2-methyl-2-(methylthio) propionaldehyde O-(methyIcarbamoyl) oxime, applied as a sidedressing to 4 to 5-acre plots of cotton provided effective control of Anthonomus grandis Boheman for several weeks. Mortality of released laboratory-reared boll weevils indicated control for 2-4 weeks; the number of punctured squares and adult boll weevils, sampled with a tractor-mounted insect-collecting machine, indicated control for 3-6 weeks. Two applications of 2 lb UC-21149 per acre applied 9-10 days apart were effective for 4-5 weeks, while a single application was effective for 2-4 weeks. More bollworm, Heliothis zea (Boddic), and tobacco budworm, H. virescens (F.), and fewer beneficial insects were found in treated than in the untreated plots. |
