The Use of Mists in the Application of Insecticides to Cacao.

Abstract

Mist spraying is the most economic method of applying insecticides to cacao. The optimum size of the droplets is within the range of 30-100 microns, with the mean 50 microns, and must be combined with a high velocity to give good impact percentages on the target. Spraying machinery should be selected on the basis of correct droplet size and high air-stream velocity. Volumes per acre in the order of four to eight gallons of spray material give adequate coverage of mature cacao.
