Phytotoxicity of Rotten Jackfruit (Artocarpus heterophyllus, Lam.) Against Golden Apple Snail (GAS)

Abstract

The study was conducted to evaluate the phytotoxicity effect of rotten jackfruit against golden apple snail (GAS). The study was laid out using Randomized Complete Block Design (RCBD) with four treatments replicated three times with 10 samples of golden apple snail introduced per treatment and a kilo of rotten jackfruit applied on the treatment specification. The following are the treatment use: T0 – no rotten jackfruit, T1 – immediately after land preparation, T2 – during transplanting, and T3 - a day after transplanting. The study revealed highly significant result on the percentage survival of rice plants, mortality rate and egg mass of golden apple snail. Also fecundity of golden apple snail showed significant result. However, there was no significant result in the average number of rice tillers/hill, length (cm) of rice panicles, weight (g) of 1000 clean grains and grain yield/plot (kg).
