Abstract

The investigation was made of the ocurrence regularity and integrated control of Z. schinifolium rust in Ya'an area from 2010 to 201. The result of the field observation in plots indicated that the rust spores of Z. schinifolium mainly spread by airborne transmission, which was closely related to temperature,rainfall and relatived humidity. The disease of the initial time happencd between July and August,the symptom appearance was in August and the rust began to be prevalent form September to October. On that basis, the physiological indices of susceptible plants in were determined different periods. The results showed that the activities of peroxidase (POD),polyphenol oxidase (PPO),phenylalanine ammonialyase (PAL) and the content of free proline (Pro) had the significantly positive correlations with the infection index,but the content of chlorophyll had the significantly negative correlation with the infection index,and catalase (CAT) activity showed no correlation with it. In prevention experiments, the prevention effect reached 93% by use of 700 times of 15% Triadimefon WP and 700 times of 70% mancozeb WP, while the prevention effect reached 50% by use of Bordeaux mixture. In the curing experiment,the best control effect was 53.5% by use of 700 times of 70% mancozeb while the worst control effect was just 9.3% by use of Bordeaux mixuture.
