Laboratory evaluation of chlorfenapyr for control of carmine spider mite, Tetranychus cinnabarinus on tomato in Botswana

The efficacy of chlorfenapyr was studied in the laboratory against carmine spider mite on tomato. acaricide applied at five concentrations, including label rate, separated a log 10 scale. Each treatment replicated three times. LC50 and LC90 values were determined by probit analysis during different periods after application used to determine acaricide. 0.52, 0.50, 0.44 0.38 ml/L when treatments evaluated 24, 48, 72 96 hours treatment. This indicated that highly effective T. cinnabarinus adults. Probit line slopes 8.15, 6.96, 5.50 2.96 application. indicates fast change mortality with increasing concentrations. study found can be effectively control under Botswana conditions, especially combination other methods integrated pest management programs.
