Abstract

The major objectives of the present studies were to study the potential contamination patterns during mixing or spraying weeds/crops and to determine the rate of contamination on the sprayer operator. Six farmers poured concentrated u/v sensitive dye on the cap before releasing into the spray tank; blotches of dye were particularly located on the fingers of all farmers Experiment 1. Experiment 2 showed that mixing of u/v powder with water followed by leading into the spray tank and washing the spray tank resulted in contamination of the hands arms body front thights shank and feet front and back. Circle spraying on weeds using the conventional knapsack sprayer CKS single cone 1/16 inch or Jun Chong LSA/4 cones CP-15 VLV 100 and Micron Herbi CDA red at 75 cm nozzle height in an immature rambutan area resulted in contamination from the head to the feet including the back regions Experiment 3. Anti-drift 'staput' appeared to reduce/lower the extent of vertical contamination on two out of four spray operators during circle spraying on weeds at 775 cm nozzle height using CP-15 45-60 cm nozzle height in oil palm Experiment 5 or CDA 45 or 75 cm nozzle height in rambutan area Expeeriment 6.
