Notes
Knapsack sprayers are the most commonly used equipment for pesticide application to crops in developing countries. Applicators usually spray the area ahead of themselves, which means that they then wale into the spray mist and treated foliage. Dr Awadhwal, a project engineer with IRRI has now developed low-cost attachments for knapsack sprayers which minimize operator exposure to pesticides. The devices he has developed include a closed chemical transfer system, a spinning brush very low volume (VLV) pesticide applicator, and a rear-mounted mini-boom. The closed chemical transfer system minimizes operator contact with pesticides, reducing hand contamination to 20-40% of that of the usual transfer methods. Handling frequency is also reduced. The spinning brush VLV pesticide applicator and rear-mounted mini-boom both reduce pesticide exposure by keeping the spray behind the operator. All devices are lightweight and cost between US$10 and $20. Leaflets and blueprints for these knapsack sprayer attachments are available from: IRRI Engineenng Division, Box 933, 1099 Manila, PHILIPPINES
