One of control that can be done is by application of insecticides. To determine
the effectiveness of insecticide Acetamiprid, the trial has been conducted at
Block A7, Gambung field trial, Kabupaten Bandung, during ± 3 months, from
October up to December 2016. The trial was designed in Randomized Complete
Block Design (RCBD) with five treatments and four replications. The treatment
tested covered insecticide Asetamiprid 30% at 1; 0.75; 0.50; 0.25 l/ha and
control. The insecticide was sprayed six times using knapsack sprayer one day
after plucking, with one week interval. Tea shoot roller attack intensity was
observed weekly at the time of plucking. Shoot production, phytotoxicity, as
well as rainfall were also observed as a supporting data. The results showed
that after three times of spraying, insecticide Asetamiprid 30% at all
formulation doses tested could effectively suppress the attack intensity of tea
shoot roller. The last observation result, after six times spraying, revealed
that the average efficacy level relatively high, i.e. 73,24%. Therefore, for
controlling tea shoot roller on tea it could be recommended the use of
insecticide Asetamiprid 30%.
