Abstract

Qualitative assessment of Actellic, Naturalis-L, and Applaud in­secticides sprayed with the recommended dosages by means of five ground spraying techniques was conducted. The spray volume ranged between 6-233 l/fed. against whitefly on eggplant through two succes­sive seasons at Damietta area. Sensitive cards were mounted on egg­plant, spray collectors and ground wires were used also to determine the spray coverage and the spray lost on ground between plants. All treat­ments were applied as a placement spray technique. Number and size of leaves of different levels of eggplant and its distribution percentages were determined. The coefficient of curling was calculated for eggplant. Performance rate of the tested sprayers was determined. According to quality of spray coverage, the ground machines could be arranged de­scendingly as follows : knapsack motor sprayer "Arimitsu". knapsack sprayer "Solo", Micron ULVA, Semco sprayer and conventional sprayer. A positive relationship was found between application rate and the lost spray. About 25% from droplets were deposted on the lower surface of the leaves of different levels of eggplants with the low-volume sprayers : Micron ULVA, Semco, and Solo sprayers, respectively.
