The compatibility study conducted for the control of Myzus persicae and leaf spots and die back diseases of chillies showed that combination of insecticides and fungicides like met-hamidophos with maneb/captafol arid FMC 35001 with maneb/captafol had an additive effect in the control of aphids. The systemic inseeticides pirimicarb and methamidophos proved superior in toxicity by giving 89.6 and 85.3 per cent reduction of white aphid population respectively while FMC 35001 gave 77.0 per cent reduction and methyl–pirimiphos 20.44 per cent only. For leaf spot diseases, captafol in combination with insecticides was proved better as against maneb. The die back disease of chillies was checked effectively by most of the insecticidal combinations with maneb and captafol respectively. The different combination of insecticides and fungicides tested was found to be compatible and they were not phytotoxic.
