在1966年马来西亚爆发橡胶季风性落叶病和果腐病后,我们对于疫霉菌及其引起的病害有了更多的了解。在马来西亚,引起割面条溃疡病的棕榈疫霉菌分布广泛,因而可能是本地产的。新的落叶病的病原菌与已知的疫霉菌种部不相同,它虽有P.meadii的某些性状,并曾一度被当作这个种,但现在已认为是一个新种了。此菌的分布限于落叶病区,从地理分布 After the outbreak of rubbery monsoon deciduous and fruit rot in Malaysia in 1966, we learned more about Phytophthora capsici and the diseases it caused. In Malaysia, Phytophthora capsici, which causes cut noodles and ulcer disease, is widely distributed and may therefore be locally produced. The new defoliating pathogen is different from the known Phytophthora species and although it has some of the properties of P. meridii and was once considered as this species it is now considered a new species. The distribution of the bacteria limited to deciduous ward, from the geographical distribution
