ontrol studies had been conducted under laboratory and field conditions on Monacha cartusiana snail. Laboratory studies was carried out to evaluate the effect of Diesel oil on egg hatchability of the same land snail M. cartusiana with three application rates 10,20 and 30 L/Fe.Result assured that no any egg can hatching when Diesel oil applied with three application rates. On the other hand, when Diesel oil applied under field conditions to control M. cartusiana snail,with application rates 30 L/Fe., the reduction rate was 5.07% only. Regarding evalution of three application methods (hand sowing, underplant stack and piles on plastic pieces) for metaldehyde and methiocarb, under field condition. Results revealed that per cent reduction of metaldehyde and methiocarb (as ready made bait) were markedly increased when, applied as hand sowing as compared when they used as piels on plastic under plant stacked.
