54 SCALE PESTS OF COFFEE 



When and where the monsoons are deficient so that 

 the fungi do not operate, or operate but feebly, it is 

 especially recommended to adopt the remedial measures 

 enumerated. 



(1) Spraying and brushing are the best artificial 

 methods of keeping the pest under control. The best in- 

 secticide found up to the present is the fish oil resin soap 

 prepared and sold by the Madras Fisheries Department, 

 and the best type of sprayer is a pressure sprayer. 



The insecticide should be used at the rate of one 

 pound to two gallons of water. The cost of spraying will 

 be, on an average, about Rs. 17 per acre. 



(2) All nests of ants should be systematically de^ 

 stroyed. 



(3) The fungi should be spread over the estate im- 

 mediately after their appearance by tying up branches 

 containing them to trees which do not show them. 



(4) The efficiency of these should be increased by 

 proper selection of shade trees and the regulation of the 

 shade and by preventing rapid surface evaporation in 

 young coffee through the agency of a cover crop.
