This standard gives the morphological characteristics of the sexual and asexual state of the Phytophthora infestans, and the signs and conditions exhibited on the host. At the time of identification, the morphological characteristics of sexuality and asexuality, or the morphological characteristics of one generation can be taken as the basis for identification.

For materials from infected areas, the loading vehicles and Packaging Materials. Then, directly take the site with suspicious symptoms; if no suspicious symptoms are found, then 5% of the proportion of reproductive material Take samples and bring them back to the laboratory for inspection; if the number of samples is less than 10, all are taken.5 Test methods5.1 symptom check Carefully inspect the leaves, branches, stems and capsules of the rubber, especially if the young leaves have symptoms of rubber South American leaf blight.
