藤椒锈病的发病规律与药剂防治研究

A Study of the Occurrence Regularity of Zanthoxylum schinifolium Rust Disease and the Control of it

  • 摘要: 2010年~2011年,对藤椒锈病的发病规律与化学防治进行了调查及研究。田间定点观察结果表明,藤椒锈菌孢子主要通过空气传播;藤椒锈病的发病情况与温度、降雨量和相对湿度关系密切;该病的始发期为7月~8月,发病期为8月份,9月~10月份为发病盛行期。在此基础上,测定了自然发病状况下感病植株在不同时期的生理指标及其与锈病发生的关系。结果表明,过氧化物酶(POD)、多酚氧化酶(PPO)、苯丙氨酸解氨酶(PAL)活性、游离脯氨酸(Pro)含量均与病情指数呈显著正相关,而叶绿素含量与病情指数成呈显著负相关,过氧化氢酶(CAT)活性与之无相关性。预防实验中,15%粉锈宁700倍和70%代森锰锌700倍预防效果达到93%,而最差的波尔多液预防效果也达到50%;治疗实验中,相对防治效果最好的70%代森锰锌700倍才为53.5%,最差的波尔多液仅为9.3%。

     

    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.
