Controle químico de mosca branca na cultura da berinjela em função do volume de calda e do espectro de gotas.

The objective of this work was to determine the influence of application rate and distribution uniformity of insecticide application for controlling the white fly (Bemisia tabaci) on eggplant plants. On the field were run some tests to sample the white fly nymphs and adults in the third apical and the medium of the eggplant plants and characterization of the droplets spectrum population. The sampling the white fly (B. tabaci) nymphs and adults was before the insecticide application and on the 4th, 7th, 14th and 21th days after that and control. Each test was a combination of equipment, nozzles type and application rate. Best coverage and small droplets was obtained with low application rate The best control of white fly nymphs and adults was the treatment with manual knapsack sprayer with constant pressure valve 2 bar, nozzles API 11003 and 500 L/ha.
