Controle do crescimento de Phytophthora palmivora por pentaclorofenol
The present report concerns the formulation of an optimal medium for the growth of the cacao pathogen microorganism Phytophthora palmivora Butl (Butl), a fungus that causes on cacao the so-called "black-pod disease" outside its natural habitat. Glucose and lactose proved the best carbon sources. Glucose was also the most suitable energy source. Glycine proved the best nitrogen source. Thiamine and cholesterol were employed as growth factors. The growth of the fungus on cocoa-pod shell was tested and compared to its growth in synthetic medium after the addition of pentachlorophenol, which was found to inhibit, partially or completely, the growth of P. palmivora in both cases. The importance of observations concerning the control of black-pod disease are discussed
