| Abstract | ||
| Plants of Santonia (Foliage), Red Pepper (fruits) and Pomegranate (fruit’s Skin peel) were extracted in boiled water, filtered and the obtained extracts were used as crude extracts. Also, the acetone extracts of these plants in addition to Fennel (seeds), Black pepper (Fruits) and Neem (seeds) had been screened in laboratory for their molluscicidal activities against glassy clover snail; Monacha obstructa (Pfiffer), three concentrations of each plant crude extract were tested as bait, residual film, leaf-dipping and repellency technique. Results indicated that, water extracts had no effect on snails, and no mortality of snail individuals was recorded. Acetone extract of Fennel exhibited more toxic effect than other plant extracts on bait and dipping technique. The efficiency of Fennel and Pomegranate was the highest followed by Black pepper, Santonia, Red pepper and Neem on residual film technique, while in the repellency tests, Santonisa and Neem exhibited high repellent action than other plant extracts. In order to identify the plant extract components, the extracts were subjected to thin layer chromatography technique.The extracts of Black pepper, Pomegranate, Fennel, Santonia, Red pepper and Neem contained 5, 2, 3, 2, 6 and 3 spots, respectively. The acetone extract of Black pepper yielded 5 fractions having (RF) values of 0.4, 0.5, 0.6, 0.8 and 0.9 cm. Other plant extracts showed different developed fractions. | ||
