| Abstract | ||
| The experiments were conducted to study the effect of foliar fertilizer (NPK), two types of Organic fertilizers (farmyard manure and compost), two growth regulators (salicylic acid, Paclobutrazol) and one recommended acaricide (Biomectin) on population of two spotted spider mites Tetranychus urticae Koch in bean plants, Phaseolus vulgaris L.var Nibraska. The number of mites was recorded before and after treatment. Biomectin caused highest reduction in mite population (96.72 % reduction) followed by Surfactant and Biomectin with Surfactant which were recorded 92.09 and 70.45 %. The effect of fertilizers showed that the highest reduction (47.49 %) was occurred under soil addition of compost. Paclobutrazol as a growth regulator achieved the highest T. urticae population reduction (96.95%). | ||
