The WS-5CD ULVA+ can apply insecticides and fungicides to various row crops e. g. cotton, groundnuts, rice, vegetables, etc., (and it can also be used for the control of migrant pests with ULV formulations e. g. locusts, grasshoppers and armyworm). The sprayer produces relatively small spray droplets which are distributed and deposited by wind and gravity, allowing several rows/metres to be treated during each spray Specially designed Micropak backpacks can be supplied for use with the WS-5CD ULVA+, with a refilling system to refill the one litre spray bottle fitted to the spray head.
