Field experiments had been conducted using different pesticides commonly used on vegetable crops searching for suitable compound could be successfully used in controlling of the glassy clover snail, Monacha cartusiana, during the activity period at Sharkia Governorate. The obtained data clearly showed, the percent reductions of snail under field conditions were significantly differed from one pesticide to another and from vegetable crop to another more over the date of examination after application was also affected in addition to; densities of infestation, the crop cultivation rates, ecological behavior of the snails and types of dispersion in each crop. Since, the tested pesticides reduced snails’ population in squash with varying degrees, the general means of percent reduction three days after application recorded maximum reduction with malathion and methomyl with 57.26 and 53.61 % reduction, while the least effects were recorded with imidacloprid and acetamiprid with 31.25 and 27.07 %. The same trend was observed two and three weeks after application with a slight increase or decrease in reduction percentages with all tested compounds. On the other site, the tested pesticides reducing populations on cabbage one week after application with maximum reduction by methomyl and malathion, 56.09 and 52.51 %, while the least effects were recorded with acetamiprid and imidacloprid with 30.61and 26.51% reduction, respectively. When regarding reducing in snails’ populations on eggplant three weeks after application, the highest effect was recorded with malathion; moderate effect was with fipronil while imidacloprid showed the least effect in reduction. As soon as, on tomato one week after application, the reduction recorded with malathion was 57.25 % followed by methomyl 53.60 %, while with imidacloprid 31.25 % and acetamiprid 27.07 % reduction percentages. On green pea the efficacy of pesticides after the third week of application reducing the populations with highest effect by methomyl; moderate effect with fipronil while the least effect recorded with imidacloprid. While in spinach one week after application the reduction percentages recorded 59.24 % with methomyl, 55.47 % with malathion, 32.33 % with acetamiprid and 28.01 % reduction, with imidacloprid moreover the same trend was observed two and three weeks after application. Generally, the molluscicidal determination of all tested pesticides in controlling the glassy clover snail, M. cartusiana infesting vegetable crops under field conditions at Sharkia Governorate could be arranged as; total general means of percent reduction, after four weeks of application as follows: Methomyl > Malathion > Emamectin benzoate > Fipronil > Acetamiprid and Imidacloprid with percentage reductions of 59.06, 54.24, 47.77, 43.26, 30.75 and 28.96 %, respectively.
