Experimental studies were conducted under field conditions by adopting methods friendly with the environment at Damietta Governorate represented at Fareskure, El-Zarka and Kafr Saad districts in addition to Sherbeen district in El-Dakahlia Governorate aimed to study the effect of tillage process and agricultural control of land snail of Monacha theba  cartusiana (Muller) and slug deroceracas reticulatum  (Muller) infecting some fruit trees such as lemon, orange, guava and peach, during winter and spring seasons, 2007/2008. The tillage process in each treatment was carried out into two levels according to the tillage depth of 15cm and 25cm in comparison with samples treated by Lanit 90 as molluscicides in each district. These three treatments were compared with others un- treated as a control to show the natural population of land snail and slug to tillage on 15cm depth (site1), tillage on 25 cm depth (site 2) and plots which treated with Lanit 90 (site 3). The effect of tillage in site 2 was more effective than site 1 in most samples and was similar to site 3 and sometimes more effective on lemon and guava than in orange and peach, respectively.
