A new fungicide to control black stripe disease of rubber (Hevea brasiliensis)

Abstract

A new fungicide code No. San 374 F4 PA09 significantly controlled the spread of black stripe disease on four Hevea clones, artificially inculated with Phytophthora meadii. The same fungicide caused a decrease in the number of depression on the bark in naturally infected trees, although the length of depressions were not reduced. The number of lesions formed owas less after the application of San 374 F4 PA09 compared with all other fungicides tested.
