Abstract:
The Phytophthora species collected from black pepper from the different
locations of north Kerala showed similar morphological characters and were
identified as Phytophthora palmivora (Butler) Butler. Based on the growth
characteristics on carrot agar, L/B {length by breadth) ratio and pedicel length of
the sporangium all the black pepper isolates of P. pa/mivora obtained in the
present investigation can be placed in MF1 or MF2 or MF3 (Griffin, 1977) or group
I or II (Zentmyer et ai., 1977) due to the overlapping of characteristics described
for them.
