Description
Summary:Methomyl , patassium sulfonate solution salt and copper sulfate weretested against land snail Monacha cartusiana which was considered a mainpestes attaking cucumper crop.Under the laboratory conditions the incubation period influencedsignificantly by the three tested compounds. Methomyl, potassrm sulfonate andcopper sulfate prolonged incubation period to 22 . 75 , 21. 25 and 20.00 dayscomparing to 17.50 days in case of control. The tested chemicalsconcentrations decreased hatehability percentages to 38.38, 43.33and 56.31%for methomyl, potassium suffonate and copper sulfate, respectively. comparingto 97.00% in case of contrl. After one day of exposure mortality percentageswere ranged between 23.75% - 43.25% 19.50 – 39.75% 18.50 – 37.50% andincreased till reached 71.50 – 86.75%, 57.75 – 83.50% and 45.75 – 64.00%after 3 weeks of exposure for methomyl, potassium sulfonate and coppersulfate, respectively.Under field conditions reduction perceutages increased as theconcentrations increased and reached the highest reduction after 3 weeks.Reduction percentages ranged between 52.75 – 77.50% , 47.50 – 74.75% and40.00 – 61.25% for methomyl, potassium sulfonate and copper sulfate,respestively.The effect of the three chemicals on cucumber yield showed possitivelyincrease compared with control. The increase percentages in cucumber yieldwere ranged between 24.00 – 42.91% , 16.6 – 35.14% and 3.38 – 22.30% formethomyl, potassium sulfonate and copper sulfate, respectively.
