Studies on the chemical control of Phytophthora palmivora (Butl.) Butl. on Theobroma cacao L. in Nigeria, 2: Persistence of fungicides on pods
The tenacity of a number of fungicide formulations when sprayed on to cocoa pods has been tested by applying artificial rain produced in an experimental rain tower. A general relationship between leaching of deposits and rainfall has been obtained. The effect of incomplete drying on the tenacity has been correlated with observations in the field. The effect of pod growth on the attenuation of fungicide deposits was demonstrated and possible improvements to formulations and spraying techniques are discussed.
