Conteúdo: |
Foot rot epidemics of black pepper (Piper nigrum) caused by Phytophthora palmivora are usually observed when plants are of bearing age (2 or more years old). Younger plants also are susceptible, and may collapse rapidly if inoculum concentrations are high. In areas new to black pepper cultivation, the amount of inoculum in the soil probably is low. Consequently, development of root infections into severe foot rots at the soil line occurs slowly. An increase in number and mobility of infective zoospores results in increased infection, rapid deterioration of roots, and collapse of the infected plants. Several commercial varieties are equally susceptible. Grafts on disease-resistant Piper colubrinum deteriorate after the 4th year. |
