The effect of TF nanoemulsion formulation on Pomacea maculata, pest of rice


Jamaludin, Shahira Husna (2016) The effect of TF nanoemulsion formulation on Pomacea maculata, pest of rice. [Project Paper Report]


Apple snails, Pomacea maculata had been recognized as the major pest in paddy field quite some time ago in Malaysia. It had given a bigger impact towards the production of rice. Botanical molluscicide which extracted directly from the plant that contains saponin as bioactive compound might be able to help in controlling apple snails. It also appears to be safe for human and the environment since it does not gives toxic residues instead of using chemical mollusicicides. Therefore, this study was conducted to measure the efficacy of TF nanoemulsion formulation towards P. maculata which is the mortality bioassay. Five different concentration of eight of TF nanoemulsion formulation against niclosamide was used in bioassay experiment. 1-2cm of five snails was immersed in each of the treatment and replicated for four times. Mortality of apple snails was recorded for every 30 minutes until all snails were died. LT50 were determined by using Probit analysis. Among all concentration and formulations, TF6 nanoemulsion formulation with 10000 ppm had the lowest value of LT50 which is 164 minutes to achieve 50% mortality of P. maculata. Whereas, LT50 value for niclosamide (positive control) is 114 minutes. Therefore, from this study, TF6 nanoemulsion formulation could be a potential botanical molluscicide in controlling population of apple snail because it was comparable with niclosamide. Eventhough niclosamide gave 100% mortality effect towards apple snail but it would give negative impact for human’s health and environment.
