Title StatementIntegrated research on testing insecticides (ultra low volume) for cotton production
General NoteMunoz, Nueva Ecija: CLSU, 1981. pp. 90-97. -(PCARR-CLSU PROJ. No. 170; Study II-A.3)
Summary, Etc.Five combinations of different ultra low volume (ULV) insecticides were tested for controlling insect pests in cotton. Deltapine 16 cotton variety was planted in 1 ha of land divided into three blocks of five plots each. The treatments were assigned at random. The ULV insecticides were found effective in controlling Aphis gossypii Glover (aphid), Empoasca biguttula Ishida (leafhopper), Helicoverpa armigera Hubner (bollworm) and Earias cupreoviridis (spiny bollworm). Aphids and bollworm were best controlled in Treatment 1 (Thiodan 25 ULV + Brassicol 75 WP), with mortality rates of 44.33 and 40%, respectively. Leafhopper mortality was highest at 38.40% in Treatment 5 (Permethrin ULV). For spiny bollworm, Treatment 4 (Temik 15 G + Sevimol + Phenthoate) effected the highest mortality rate of 77.27%. Treatment 1 gave the highest yield with a mean of 72.46 kg seed cotton/plot. It also had the highest net return of P2,584.73 or an earning of P1.15 per peso invested
