Comparative efficacy of chemical and botanical pesticides against citrus leaf minor (Phyllocnistis citrella Stainton)

The investigation was conducted with 8 Treatments:-Dimethoate 30 EC @ 0.03 per cent, Abamectin 1.8 EC @ 0.003 per cent, Spinosad 45 SC @ 0.03 per cent, Acetamiprid 20 SP @ 0.04 per cent, Imidacloprid 17.8 SL @ 0.005 per cent, Neem oil 2 per cent, NSKE 5 per cent and control (water spray) on citrus leaf minor.

In overall, cumulative effect of 3 applications of all the treatments T 5 Abamectin 1.8 EC (0.003%) recorded lowest (7.66%) leaves infestation of leaf minor and found at par with T 2 Spinosad 45 SC (0.03%) i.e.8.42 per cent leaf infested. The next best effective treatments, T 4 Acetamiprid 20 SP (0.04%), T 3 Imidacloprid 17.8 SL (0.005%), T 1 Dimethoate 30 per cent (0.03%), T 6 Neem oil (2%) and T 7 NSKE (5%) with infestesion of 9.37 per cent, 10.46 per cent,13.08 per cent, 14.63 per cent and 15.21 per cent, respectively and these treatments groups were at par with each other.
