A SUCCESSFUL “MOBILE SLUG AND SNAIL CONTROL DEVICE” BY PHYSICAL METHOD: AN INNOVATIVE IDEA AND ITS APPLICATION

Slugs and Snails are belongs to the second largest phylum, Mollusca. They are an important crop and ornamental plant pest in horticulture and agriculture. In West Bengal there are many slug and Snail species which damage the agricultural field. There are so many traditional methods like chemical method, physical method, habitat modification, Traps, natural enemies etc. to control the snails and slug. But there is not a single method gives a satisfactory result. Our innovation is to control slugs and snails by Physical method (electric shock from cattle urine). By using Cu & Zn plate as electrode we produce 0.6V-0.9V electricity which protects the crop or agricultural field from soft bodied slug and snail. The cost of our present device is very low cost or no cost. The ranges of success were 87% - 98.33% and79.2- to 92.33% in case of Laevicaulis alte, Macrochlamys sp respectively. The success rate is little bit higher in case of Laevicaulis alte then Macrochlamys sp. It is possibly due to presence of shell in the later species. The tolerance level also varied due to body size which is directly proportionate.
