Extract

The past decade has seen considerable advance in the production of cotton from Rhodesia and the adjacent former Federation territories of Malawi and Zambia, brought about very largely by the introduction of effective pest control measures originating from the work of the Cotton Pest Research Scheme, located at Gatooma, Rhodesia.

Complementary to a work programme investigating the type and formulation of insecticides capable of controlling an insect pest complex including bollworms, jassids, aphids and stainers, attention has been given to the design of spray equipment suited to both extensive European and intensive African forms of cultivation. The “tailboom” modification to the conventional knapsack sprayer has been developed and this versatile piece of equipment in several mechanised guises forms the basis of the recommended ground spray machinery.
