Abstract
Experiment was conducted at National Tea & High Value Crops Research Institute, Shinkiari, Mansehra-Pakistan during 2011-12 with the objectives to evaluate the efficacy of different chemical pesticides i.e. Tarzan (Cypermethrin 10EC), Piceal (Alphacypermethrin 10SC) and Buzer (Alphacypermethrin 10% W/V) were used to compare their effectiveness in relation to control the aphid infestation on growing shoots and their control at nursery stage. The mortality of aphid on tea cutting significantly affected under chemical pesticide Tarzan caused highest mortality 64%, 63%, 52%, 55%, 59%, 59%, 41% and 54% respectively, pesticide Piceal ranked second in relation to efficacy against aphid with insect mortality 36%, 40%, 40%, 28%, 37%, 36%, and 43% respectively. Whereas insecticide Buzer showed less efficacy among the other two insecticides on all tea cuttings application after 24 hours. Similar trend was observed in other treatments.
