摘要
[目的]为了明确霜脲氰与丁子香酚、氟噻唑吡乙酮与蛇床子素对樱桃茎腐病的联合生物活性和田间防治效果.[方法]室内采用菌丝生长速率法测定霜脲氰与丁子香酚、氟噻唑吡乙酮与蛇床子素不同比例混剂对樱桃茎腐病菌的生物活性,进一步通过田间试验测定防效.[结果]室内生物活性测定结果表明:霜脲氰与丁子香酚、氟噻唑吡乙酮与蛇床子素的质量比分别为50∶1、5∶1时,对樱桃茎腐病菌抑制效果最好,增效系数分别为1.82、1.83;根据最佳质量比配制的药剂10.2％霜脲氰·丁子香酚悬浮剂和4％氟噻唑吡乙酮·蛇床子素水乳剂,其田间施药量为153、24 ga.i./hm2,10 d后防效可达87.5％和91.02％.[结论]霜脲氰与丁子香酚复配、氟噻唑吡乙酮与蛇床子素复配,对樱桃茎腐病防治效果好,可达到降低化学农药使用量,减少农药抗性的效果.
Abstract
[Aims]This study aims to clarify the combined biological activity and field control effect of cymoxanil· eugenol,oxathiapiprolin·cnidiadin on cherry stem rot.[Methods]The mycelial growth rate method was used to determine the biological activity of mixtures of cymoxanil and eugenol,as well as mixtures of oxathiapiprolin and cnidiadin in different proportions against cherry stem rot pathogens.Further field experiments were conducted to determine the control effect.[Results]The results of bioassay in laboratory showed that when the mass ratios of cymoxanil to eugenol and oxathiapiprolin to cnidiadin were 50∶1 and 5∶1 respectively,the inhibitory effect on cherry stem rot pathogen was the best,with synergistic coefficients of 1.82 and 1.83.According to the optimal mass ratio,the pesticides cymoxanil·eugenol 10.2％SC,and oxathiapiprolin·cnidiadin 4％EW were applied in the field at doses of 153 and 24 g a.i./ha.On day 10 after application,the control effects could reach 87.5％and 91.02％.[Conclusions]The combinations of cymoxanil and eugenol,as well as oxathiapiprolin and cnidiadin,have a good control effect on cherry stem rot,with an effecto of reducing the amount of chemical pesticides and pesticide resistance.
