Abstract

The control efficacies of different tissues extracts of 30 plants against Pseudoperonospora cubensis was tested by the leaf discs tests. The results showed that the extracts of the leaf of Piota orientalis (L.) Endl.,the leaf of Pinus massoniana Larmb. and the stem as well as leaf of Euphorbia helioscopia L. had a good control efficacies of 100.0,100.0% and 93.3%,respectively. The other plant extracts didn't have any control efficacy. The pot tests of these three plant extracts showed that their control efficacies at 7 days were 95.2%,96.5% and 93.9%,respectively.
