It is gerbera, aster, carnation, Christmas flower, tomato and other plants. Important pathogens (see Appendix A). Mainly with strong anti-reverse oospores in the medium soil and host residues in winter and long-term survival, When the field temperature and humidity are appropriate, the oospores break the dormant germination and produce sporangia. Sporangia soon after rain or after irrigation The release of a large number of zoospores, eventually invading the host through the roots or wounds, can cause roots and stems to rot, causing the plants to be infested after infection Wilted and died. 2.3 Identification basis The symptoms of the Phytophthora infestans on the host plant, the morphological characteristics of the pathogen, and the biological characteristics are the basis for identifying the bacteria.
