Tropical developers formulas

The problems of diseases and pests will not be solved merely by a chemical formula that inhibits or destroys fungus spores in vitro. A pesticide ought to have the ability to remain on the plant surfaces long enough to prevent or destroy disease agents and to destroy disease vectors before they attack. This is difficult to achieve under the severe weather conditions of the tropical moist forest, the natural habitat of cacao, where the chemical deposited is in many cases washed away by heavy rain. The inherent tenacity of a fungicide could be improved by the addition of adhesives. An effective adhesive or an alternative for use in combination with fungicides or insecticides in the tropics has not yet been developed.
