| Summary: | A field evaluation of neonicotinoid insecticides; Imidacloprid, Acetamiprid and
Dinotefuran using recommended concentration against leafhopper, was studied.
Insecticide application were conducted against leafhopper infesting brinjal, chilli and
long bean for two cropping period under field conditions in UiTM Melaka, Jasin
campus. According to percentage reduction over control, Imidacloprid was found to
be the most effective treatment in reducing the pest population on brinjal. As for chilli
and long bean test crop, Acetamiprid was the most effective treatment. All three
treatments showed no significant different in residuality effect against leafhopper on
all three tested crop as they last up to 14 DAA against leafhopper population.
Imidacloprid and Acetamiprid showed the highest percentage increased yield over
control for brinjal and long bean respectively. Imidacloprid, Acetamiprid and
Dinotefuran were effective in giving high yield and protecting the crop against
leafhopper when compared with untreated (water). From this study, the use of
insecticides using its recommended dose is proven to be effective in controlling
infestation of leafhopper on crop. Therefore farmer should be wise in using
insecticides which could help them in managing the cost of crop protection,
environment as well as their own health. In the end farmer will have many option in
choosing any of the neonicotinoid insecticides tested in this study. |
