Efficiency of some Natural Plant Extracts and Ferrous Sulphate in Controlling the Land Snail (Monacha cartusiana) under Laboratory and Field Conditions at Sharkia Governorate, A.R. Egypt.

Abstract

The effect of different concentrations of Azadirachta indica (neem)leaves powder ,Calotropis procera (oshar)leaves powder, oshar leaves crude extract, Capsicum annum (Cayenne or spicy red pepper)fruits powder and Piper nigrum ( black pepper) fruits powder as natural extracts and ferrous sulphate as chemical compound were evaluated as attractive toxic wheat bran baits against the glassy clover snail Monacha cartusiana under laboratory and field conditions at Sharkia Governorate, A.R. Egypt Results revealed that the tested materials exhibiting noticeable molluscicidal effects under both laboratory and field conditions. Mortality percentages increased with increasing concentration values and duration of exposure . Population reduction percentages revealed the same trend when the tested materials were applied 7 days post-treatment under field conditions . Ferrous sulphate was the most effective one followed by spicy red pepper,neem, black pepper, osharfreshleaves crude extracts and osharleaves powder extract where mortality percentage of effected snails were 100, 70, 50, 45, 45 and 10 respectively at highest concentration 7 days post-treatment. The parallel % population reduction values were 90, 70, 60, 50, 20 and 20 respectively.
