Abstract

Field tests were conducted in North Tahreer Company, the Spraying was done on Citrus trees. Two methods of spraying were used with both ground and aerial sprayers. For each method two tests were done with and without viscosity modifier. Samples were spread on the citrus trees to measure the droplet size, the spraying uniformity, the penetration inside the trees, and drift potential. Sensitive cards to the spray drops were used to collect the spray spectrum either on the top or bottom leaf surfaces. Better spraying performance with viscosity modifier was obtained by aerial application, method.
