PEMBERIAN BEBERAPA KONSENTRASI EKSTRAK BROTOWALI (TinospoacrispaL.) UNTUK MENGENDALIKAN KEONG MAS (PomaceaSP.) PADA TANAMAN PADI (OryzasativaL.)
Abstract: Rice is an important
crop in Indonesia, because it contains carbohydrates, protein, fat, fiber,
vitamins, and trace elements. Pomacea sp. is a major pest of rice crops in
Indonesia. Use of plant molluscicides like Tinospora crispa L. is an
alternative to reduce the use of synthetic chemical pesticides. This study
aimed to obtain the concentration of Tinospora crispa L. capable of controlling
the Pomacea sp. in riceplant. This research was conducted at plant pest laboratory, Faculty of
Agriculture, University of Riau and in the experiments farm of the Faculty of Agriculture University of
Riau.This research using a completely randomized design (CRD), which consist of
5 treatments and 4 replications. There are
extracts Tinospora crispa L. 0
g/l of water, 25 g/l of water, 50 g/l of
water, 75 g/l of water, 95 g/l of water. Concentration of Tinospora
crispa L. 75 g/l of water is able to
control Pomacea sp. The result indicated that concentration of 75 g/l of water
can cause initial time of death is 12 hours after application, LT50reach
in 28.25 hours and total
mortality 86,99%.
