The genotypes of true resistance to blast or some main cultivars or Hcilongjiang Province were tested by spray inoculating with the physiological races of Piricularia oryzae with the ability to differentiate the resistant genes to blast namely: 037, 007, 033, 035, 017, 333, 137,101.

Synthesis and antifungal activity of 3-trifluoromethyl-4-amino5-mercapto-1,2,4-triazole derivatives;

Synthesis and antifungal activity of 3-methyl-4-amino-5-mercapto-1,2,4-triazole derivatives;

Synthesis and antifungal activity of 1-(1H-1,2,4-triazol-1-yl)-2-(3,3-dimethyl)-3-[(4-substituted)piperazin-1-yl]-2-propanols;

To search for more potent and less toxic antifungal agents,Four 2(2,4Diflurophenyl)1(4alkylpiperazine1yl)3(1,2,4triazole1yl)2propanols were designed and synthesized,and their antifungal activities in vitro were determined.

The antifungal activities of.

To exploit the highly effective natural antifungal medicaments from sea cucumbers,water-soluble holothurian glycosides from Apostichopus japonicus were isolated and purified,and their antifungal activities were examined.

Objective: The studies dealt with in vitro antifungal activity against seven pathogenic superficial fungi by means of aqueous and ethanol extracts from six kinds of traditional Chinese medicines (TCMs).
