La lutte chemique contre Phytophthora palmivora au Cameroun

The seriousness of Phytophthora palmivora in the Cameroun, where it is estimated that annual losses reach 50 percent of the yield, calls for chemical control. 1. Ecological conditions differ between the East and West Cameroun and necessitates different types of treatment. 2. The need to improve experimental techniques has led to certain changes in experimentation, including the technique of "miniaturisation". 3. Using this technique, several fungicides have been studied, including both copper and non-copper fungicides. 4. Using radioisotopes, the residual effect of organic tin sprays has been studied. Residues are of low order. 5. The spray programmes must be adjusted to rainfall. 6. In chemical spraying, climatic conditions are very important in particular rainfall. Spraying has proved efficient and profitable in East Cameroun, but further work is needed in the West
