为了明确氟啶胺和咯菌腈及其复配物对草莓灰霉病菌的室内毒力,研制新的防治草莓灰霉病药剂配方并明确其田间防效。采用生长速率法研究了氟啶胺、咯菌腈及其复配物对草莓灰霉病菌的室内毒力,以Wadley法进行增效作用评价,并验证该复配物对草莓灰霉病的田间防效。结果表明:氟啶胺和咯菌腈以质量比1∶5、3∶2复配对草莓灰霉病菌具有增效作用,其增效系数分别为1.82和2.07;氟啶胺和咯菌腈以质量比1∶1、1∶3、2∶3、2∶1、3∶1、4∶1复配对草莓灰霉病菌具有相加作用,但以质量比5∶1复配时,则表现拮抗作用;氟啶胺和咯菌腈以3∶2复配对草莓灰霉病的田间防效最高可达91.00%,比使用单一化学药剂效果好,而且...

A novel pesticide was created by joint-toxicity detection of mixtures of fluazinam and fludioxonil in order to control strawberry gray mold. The mycelial growth rate testing was conducted to determine the laboratory toxicity efficacy of fluazinam, fludioxonil and their mixtures on Botrytis cinerea. The synergism effect of the mixtures were then evaluated by Wadley method. And the field experiment of the mixture with the most significant synergistic effect was carried out to verify its control effect on strawberry grey mould. The results showed ...
