A survey of pesticide application in Cameroon

Abstract
Surveys of those applying pesticides in Cameroon was made as an initial part of a programme to introduce the adoption of minimum requirements for pesticide application equipment as the initial part of a programme for the sustainable improvement of rural workers and family health, to protect the environment and improve crop production efficiency. The survey considered those growing cocoa, coffee, oil palm, maize, cotton, tomatoes, groundnuts, plantains, bananas and various other crops. The main herbicides used by the growers were paraquat and glyphosate, while metalaxyl, maneb and copper were the principle fungicides. Cypermethrin and chlorpyrifos were the main insecticides. The survey showed that lever-operated knapsack sprayers are the most widely used type of equipment, but in the drier areas where water supplies are less readily available, CDA rotary atomiser sprayers are used, especially on cotton. Hand carried thermal foggers and motorised knapsack mistblowers were also used especilly in cocoa. Various problems with the equipment caused leakage on operators who generally did not wear protective clothing. The need for further training and dissemmination of information throughout Africa is stressed.
