Abstract
Plant-derived oils and a washing powder were evaluated as sprays against sweetpotato whitefly, Bemisia tabaciGenn., in field studies in India. Two cottonseed oil formulations, (Flyteck-1$) and a local formulation, castorbean oil (Flyteck-2$) , neemseed oil (Neemark $) and a washing powder (Nirma $) reduced numbers of adult whiteflies 1 day after treatment. Three days aftertreatment, the cottonseed oils and the castorbean oil were superior to neemseed oil and the washing powder. At 5 and 7 days, all treatments except neemseed oil significantly lowered the nurnoer of adults. The number of nymphs, as measured by spots on water-sensitive paper, were reduced lo:lowlng the treatment of individual leaves with cottonseed and castorbean oils at 2.0%, neemseed oil at 0.5, 1.0 and 2.0% and washing powder at 1.5,15.0 and 30.0 mill. The under-leaf coverage obtained on top, middle and lower locations of cctton plants treated with knapsack, motorized mistblower and foot-operated sprayers were compared. The foot sprayer gave the best coverage of the middle leaves where older eggs and nymphs were located. Spray coverage on the undersides of leaves is essential and extra time and effort must be expended to accomplish this goal. Also shortening spray wands and decreasing nozzle office may facilitate coverage. There was little phytotoxicity observed when individual leaves of ten cotton cultivars were sprayed with 5% cottonseed oil and Nirma washing powder at 15 and 30 mill.
