A Comparative Study on the Molluscicidal Effect of Whole Leaf and Leaf Extract of Blumea balsamifera Linn. (sambong on Pomaceae sp. (Golden apple snail)

Abstract

Two hundred seventy golden apple snails (Pomaceae sp.) were divided into six treatments: I (control), II (leaf feed method), III (12.5% leaf extract), IV (25%) V (50%), VI (75%). After 48 hours of testing, it was observed that leaf extract method is better snail control or molluscicide than the leaf feed method. The most effective left extract concentration as 75%. The 50% concentration was not able to kill a significant number of snails, but those that survived have impaired chemoreceptors and muscle fibers.
