Abstract
Abstract An unusual outbreak of the mite, Tetranychus cinnabarinus (Boisd.), was observed on squash-melon crop during June 1975. In the infested fields, the fruit development was very poor. The source of inoculum was found to be castor plant and the unusual outbreak was due to the use of carbaryl and endrin used for the control of other pests. Out of 7 pesticides, viz. binapacryl, dichlorvos, dicofol, dimethoate, dioxathion, malathion and phosalone used as high volume sprays, dimethoate @ 135 g/ha and dioxathion @ 225 g/ha (active ingredients) were found to be the most effective.
