Battery Sprayer (WS-5CD)

The WS-5CD is a simple robust hand-held spinning disc Controlled Droplet Application (CDA) sprayer powered by torch (D-cell/R20) batteries, with one set of good quality batteries giving up to twenty hours spraying time. It is designed primarily for the foliar application of insecticides and fungicides-both water-based mixtures (e. G. ECs, WPs) at 10 to 20 litres/hectare total spray volume and involatile Ultra-Low Volume (ULV) formulations at 1 to 3 litres/hectare. An electric motor spins the atomiser disc to produce uniform spray droplet size ranges (the actual size of droplets produced depends on the atomiser disc speed which is determined by the number of batteries fitted). Liquid is fed by gravity through colour coded feed nozzles. The 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.
