Abstract

The research was interested in finding out if the neem leaves can serve as a molluscide. In this experiment 240 Achatina achatina were used. Twenty snails were randomly selected and placed in each green house representing a treatment. There were four groups. Group 1 served as control without any neem leaf. Group 2 received 100% of the neem leaves extract. Group 3 received 70% of the extract while the group 4 received 50% of the extract. The extraction of the neem leaves was done using alcohol as extracting reagents using cold maceration method of extraction. The experiment lasted for eight days and replicated three times. The result obtained was subjected to analysis of variance (ANOVA) at P0.05. There was significant difference P0.05 in the longevity of the snails in different treatments. This indicates that the neem leaves are molluscides.
