Abstract
The study evaluated the molluscidal potential of Zeolite (clinoptilolite) with aqueous extract of selected plants namely Eleusine indica (L.) Gaertn, Chloris barbata Sw., and Tridax procumbens L. against Golden apple snail (Pomacea canaliculata) egg elusters and adult. Each of the four treatment concentrations-25%, 50%, 75% and 100%-was applied to egg clusters with three replicates using the spraying method, with a total of 10 mL, while the adult snails were submerged in the treatment using a total of 100 ml. The study's findings show in the treatment of E. indica with zeolite on P. canaliculata egg clusters after 168 hours of exposure had an LC50 of 8.13% and an (R2) of 0.6422, whereas H2O had an LC50 of 4.55% an an R2) of 0.662. In the treatment of C. barbata with zeolite the LC50 was 9.89% ad R2+0.6805 and with H2O has an LC50 of 10.38% and R2=0.606. T. procumbens with zeolite has LC50=19.45%, R2=0.7058. T procumbens with H2O has an LC50+18.74% and R2+0.7071 and Zeolite has LC50 of 4.08% and R2=0.6303. In addition, E. indica with zeolite and T. procumbens with zeolite has the highest mortality rate of P. canaliculata adult snail in all treatment concentrations that has an average of 100% mortality in highest concentration.
The findings revealed that the concentration rises, correspondingly rises the mortality rate of Golden Apple Snail's egg clusters and adult snail. The results showed that Zeolite (clinoptilolite) with aqueous extract of specific plants has a potential molluscidal application against major pests in a less expensive and environmentally, friendly pesticidal management technique that might increase rice crop production.
