| Abstract | ||||
| This research was to manufacture a local high clearance tractor. One of its applications, which was studied in this research, was to carry a spraying system for insects and pest causing diseases. One of its advantages is that it suited spraying both crop and orchard fields. Field and laboratory experiments were carried out to study the distribution of droplet numbers, and size of the spray solution, bioassay and residual effect of Cascade (IGR) pesticide against cotton leaf worm by using tested machine and control machine, percentage of damaged plants, and field efficiency. Results indicated that insecticidal activity of Cascade which was sprayed with the tested machine and control machine had two different trends according to their insecticidal efficiency. The self-propelled sprayer gave a high insecticidal efficiency for the two larval instars with a significant differences compared with the control machine. Also, it could be concluded that the optimum forward speed and operating pressure were 2.5 km/h and 1961.3 kpa, respectively. The developed machine was proven to be run by on operator. Also, it reduced the used amount of pesticides, consequently, reduced the spraying costs and the environmental pollution. | ||||
