ITS-rDNA-RFLP analysis of poplar canker,apple ring rot pathogens and other related pathogens;

The effects of fungicides, Bacillus subtilis and fungicide with Bacillus subtilis to control the post-harvest Apple ring rot and the mechanism of disease were studied by using the plant pathological and biological methods, in order to provide the scientific basis for harmless prevention to post-harvest apple ring rot.

With the alternation of main cultivars of apple and extension of ARR(apple ring rot)-sensitive cultivar Fuji, ARR has been one of the most serious diseases, by which serious loss was caused.

Field Test of Carbendazim·Tebuconazole 20% WP For Controlling Physalospora Piricola Nose.;

Occurrence Regularity and Prevention Measures of Physalospora piricola Nose

Carbendazim+tebuconazole 30% SC showed a good control effect against Physalospora piricola Nose at 600 to 800 times after 7 times at intervals 7 to 8 days at the early stage of the onset.

Agricultural Antibiotic 120 (AA120) 4% aqueous solution, developed by Institute of Biological Control of CAAS, has positive effect on four leaf diseases of apple and pear trees: Physalospora piricola, Glomerella cingulata, Alternaria mali and Venturia pyrina in lab and fields.

Bacillus subtilis BS-98 is one of the antagonistic strains strongly againstplant fungal pathogens such as Physalospora piricola Nose.

Correlative analysis of resistance-related factors in apple fruits to apple fruit ring rot disease;

Study on the Conditions of Pycnidium Production of Physalospora piricola;

Fungitoxicity of tebuconazole against Alternaria mali Roberts and Physalospora piricola Nose was assessed by mycelial growth rate method.

This study indicated that nincomycins could inhibit the hyphase of Rhizoctonia solani kahn and Physalospora piricola.

The bacterium and its antifungal protein could inhibit Botryosphaeria berengeriana f.
