Land snails are becoming a serious agricultural animal pests In Egypt
especially in northern coastal areas. They attack numerous 0; chard trees,
field and vegetable crops as well as ornamental plants, causinq great
damage to all plant parts including fruits. The injured plants may intensely
recompile the damaged parts and the yield of crops seems not to be affected,
but at least the quality was reduced so that the vegetable crops gOI poorer
marketing ralings and was reduced in value (El-Okda, 1980 and Nakhla et et
1993). Most molluscicdes against terrestrial gastropods more usually
deployed in baits ( Barker. 2002). Bait technique is more suitable for reducing
environmental pollution. moreover simple for use, focal treatment not area
wide. thus it is usually low costly. The present study aim to evaluate the rnouuscrctcai activity of certain
