摘要
Abstract
[Objective]The powdery mildew of grape in intensive areas of Hami was investigated, to find out the rules and biological characteristics to clarify the dominant factor in disease outbreak to lest efficient toxicity screening of low - residue fungicides for grape powdery mildew Prevention to provide technical support . [ Method] The survey on time of diseases , affecting factors , medicament test was conducted in 2003 - 2009 . [ Result ] Early onset of grape powdery mildew for the beginning of June, the peak incidence was in mid - July . Temperature of 20℃ - 30℃ , large - scale cultivation conducive to disease were advantageous to the epidemics of Grape powdery mildew. The biocontrol efficiency of DuPont Fuxing, the diniconazole and 40％ WP myclobutanil are 86 . 89 ％ , 84 . 02％ and 81.32％ .[ Conclusion] The prevention diseases from their spreading should be strengthened, spraying 2 times, spraying fungicides once every 10 days can effectively control grape powdery mildew.关键词
