Abstract

Following a severe outbreak of Tetranychus neocaledonicus Andre (cucurbitae Rahman and Sapra) on brinjal [Solanum melongena] near Hissar in the Indian State of Haryana in February 1972, 19 chemicals were tested for the control of this mite. Mite population density was observed before treatment and 3, 7 and 15 days afterwards; the results are shown in a table. After three days, all treatments, including a spray of water only were superior to no treatment, and monocrotophos, dimethoate, carbophenothion, phosphamidon, formothion, diazinon, thiometon and methyl-parathion all diluted to 0.25%, malathion at 0.05% and wettable sulphur were all superior to water. After seven days, none of these sprays was more effective than water although all were superior to no treatment. After 15 days, all chemicals lost their effectiveness and mites were found distributed evenly over treated and untreated parts of the field. The effectiveness of dimethoate and phosphamidon, which had previously given good results against T. neocaledonicus [cf. RAE/A 58, 1207], was confirmed.
