DESCRIPTION
The ULVA+ 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
pass. The sprayer must therefore always be held downwind of the operator.
