    The control of golden kuhol (Pomacea caniculata) using indigenous waste
    (Don Mariano Marcos Memorial State University - South La Union Campus, 2003-03) Panelo, Analiza O.; Salvador, Zula E.
    This study conducted at Sta Rita Central from September 28 to December 25, 2002, aimed to determine the effect of indigenous materials at different concentration of the control of golden snail. It made use of CRD (two factorial) using four- (4) treatment and three (3) replication with three different concentrations. As to mortality, T1 (powdered hot pepper fruits) used in golden kuhol resulted to the deaths of all the golden kuhol. The number of deaths was followed by the number of deaths in T4 using papaya leaves then by ,T3 using neem leaves and finally by using T2 labtang leaves. As to concentration, all the concentration used gave comparable effect on mortality of golden kuhol. As to combination of treatment and concentration the best combinations were from T1 C1 (100 grams of pepper), T1 C2(200 grams pepper) and T1 C3 (300 grams pepper) in causing deaths of golden kuhol. On the number of hours exposure of dead golden kuhol to the different treatment,T3(neem leaves) gave the longest duration of time followed by, T2 (labtang leaves), T1 ( hot pepper fruit, and T4(papaya leaves) However, when subjected to ANOVA, the differences among treatment were significant. For concentration, C3 using 300 grams concentration of the different treatment gave the highest hours of exposure to the dead golden kuhol. It was followed by 200 grams concentration of indigenous waste. The least exposed indigenous waste concentration was 100 grams. These differences among concentration however were found insignificant when tested with ANOVA. The differences of time of exposure to the dead kuhol between treatment and concentration combinations are also insignificant. Based on the finding of the study, the following conclusions were derived. As to the effect of the different indigenous wastes on the number of deaths of golden kuhol, Treatment 1 or the use of powdered hot pepper fruits is the most effective indigenous wastes on the control of the population of golden kuhol, followed by papaya leaves, neem leaves and the least is labtang leaves. For concentrations, 100 g, 200 g, and 300 g, concentration of indigenous waste had comparable effect to the number of dead golden kuhol. As to the time of exposure of dead golden kuhol, the different indigenous waste were exposed to dead golden kuhol of comparable length of time, also the 3 concentration of indigenous waste gave comparable length of time exposure to the dead golden kuhol. The following were the recommendations made. The use of indigenous material s especially powdered pepper fruit as potentiaJ substitute to chemical molluscicide to control golden kuhol population. For economic reason however, papaya leaves is recommended, Similar study maybe replicated under farmer's field for verification of results.
