For pest control in a greenhouse, drift application methods of dust, smoking pesticide and liquid formulation have advantage for the operator without his exposure to chemicals. And a study of adaptation of electrostatic force for these chemicals was carried out for the purpose of improvement of deposit. The results showed that electrostatic application methods and an electric field by high voltage wires in the house, improve deposit of chemicals mainly on the under surface of leaves and pest control effects. The process of these studies will de mentioned by the series of 3 reports.
In this report, applications of fine dust formulation by knapsack type duster, smoking pesticide by axial blower and liquid formulation by non-heating fog machine were carried out. And improvement of chemicals deposit, by corona charging method and induction charging method with electric field by high voltage wires, were discussed.
