Description Effect of climatic factors on the occurrence of foilar infection in black pepper caused by phytophthora palmitora MF4 was studied during the years 1984-86 in arecanut-black pepper mixed cropping system. The correlation studies between the disease recorded at weekly intervals and the meteorological factors prevailing during the preceding seven day.m showed a positive correlation between the rainfall, number of rainy days and relative humidity whereas temperature and sunshine hours had a negative correlation. Average climatic factors worked out during increasing and decreasing phases of the disease shoe: ed that [actors such as low temperature (22.7-29.6'C), shorter duration of sunshine (2.8-3.5 h/day) high rainfall (15.8-23.0mm/day) and high relative humidity (81-99%) contributed to the increase n disease.
