PIRATE 3 
Typical cases of coconut budrot produced by inoculation with Phytophthora strains 
from coconut and cacao. 
A. —Budrot produced in healthy, vigorously growing coconut tree by merely pouring 
a zoospore suspension in rain water of the coconut strain between the growing leaves 
of the bud. Bud killed in 15 to 16 months after inoculation. 
B. —Budrot produced in a disease-free coconut tree by inoculation with a zoospore 
suspension of the cacao strain. The tree was also infested with beetles, as indicated 
by the leaves with triangular shaped portions cut out of the leafleats. Bud killed 
2 to 3 months after inoculation. The rapid production of the rot in this case was 
undoubtedly due to the beetle injury to the leaves, and also to the fact that the tree 
was not in a vigorous condition of growth.
