Protective Shield for Hydraulic Boom Sprayer

Several techniques have been employed to minimize the drift problem for both aerial and ground-level applications. Operational techniques involve careful timing of the application with proper weather conditions. Spraying is postponed when a significant wind is blowing toward sensitive areas. Mechanical techniques involve using different types of drift control nozzles, shields. Shield is a mechanical structure which is fitted over nozzle or boom that physically interrupts the wind flow which causes drift. It can be of different sizes and shapes. Shields with suitable design reduce spray drift upto 60-70 per cent. Use of such a structure is also economical and viable option to reduce spray drift.
