| Abstract | ||||
| Methomyl , patassium sulfonate solution salt and copper sulfate were tested against land snail Monacha cartusiana which was considered a main pestes attaking cucumper crop. Under the laboratory conditions the incubation period influenced significantly by the three tested compounds. Methomyl, potassrm sulfonate and copper sulfate prolonged incubation period to 22 . 75 , 21. 25 and 20.00 days comparing to 17.50 days in case of control. The tested chemicals concentrations decreased hatehability percentages to 38.38, 43.33and 56.31% for methomyl, potassium suffonate and copper sulfate, respectively. comparing to 97.00% in case of contrl. After one day of exposure mortality percentages were ranged between 23.75% - 43.25% 19.50 – 39.75% 18.50 – 37.50% and increased 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 copper sulfate, respectively. Under field conditions reduction perceutages increased as the concentrations increased and reached the highest reduction after 3 weeks. Reduction percentages ranged between 52.75 – 77.50% , 47.50 – 74.75% and 40.00 – 61.25% for methomyl, potassium sulfonate and copper sulfate ,respestively. The effect of the three chemicals on cucumber yield showed possitively increase compared with control. The increase percentages in cucumber yield were ranged between 24.00 – 42.91% , 16.6 – 35.14% and 3.38 – 22.30% for methomyl, potassium sulfonate and copper sulfate, respectively. | ||||
