Managing Phytophthora on black pepper

Abstract

Since Phytophthora infects all parts of black pepper, to prevent Its aerial infection, fungicidal spray is required, whereas to suppress soil populati.ons, biological control may be adopted. Biological control organisms are multiplied on inexpensive carrier media such as tea waste, coffee husk etc. As" the biological control organisms survive on the organic matter in soil, application of organic matter enhances their population and suppresses the population of Phytophthora in soil.
