Abstract:

The aim of the present investigation was to sort out the comparative effectiveness of some insecticidal spray schedules against Cotton Jassid on FVH-144, cotton. The trial was laid out in a randomized complete block design, with five treatments having three repeats each. The different insecticides were sprayed over the crop in four installments of a fortnight apart. The comparative effectiveness of different test spray schedules against overall spray index, as well as against the individual sprays, was considered to be an indirect reflection of jassid population per leaf. All the insecticidal spray schedules tested were found to be effective against the jassid of cotton. On numerical basis, however, T4 insecticidal spray schedule Sundaphos 60 SL (methamedophos) + Talstar 10 EC (bifenate) + (cypermethrin 10 EC + monocrotophos 40 SWC) + BTM 525 EC (cyflothrin + methamidophos) [500, 250, (250 + 500), 400] (a.i.) ml/acre was found to be most efficient against cotton jassid.
