摘要: 明确乙蒜素等杀菌剂对红掌细菌性叶斑病的抑制作用和田间防效,为天津地区红掌叶斑病的防治提供依据。本文以红掌细菌性叶斑病菌为研究对象,采用牛津杯法测定了10种杀菌剂对病菌的抑制作用;喷雾法测定了5种药剂对该病害的防治效果。结果表明:80%乙蒜素EC效果最突出,EC50为1.511 4 mg/L;其次70%代森锰锌WP、6%春雷霉素WP、90%新植霉素WP和3%中生菌素WP对红掌叶斑病菌的抑制效果明显,EC50值均较低,分别为18.348 9、60.232 1、78.666 6 mg/L和84.447 2 mg/L;46%可杀得WP、20%噻菌铜SC、30%琥胶肥酸铜WP的EC50均超过100 mg/L; 20%叶枯唑WP和72%农用链霉素WP则抑制效果最差。选试了5种药剂对红掌叶斑病进行了温室药效试验,其结果为:乙蒜素的防效最高,达76.1%;农用链霉素的效果最低,仅为27.1%。其防效依次为:乙蒜素>春雷霉素>新植霉素>琥胶肥酸铜>农用链霉素。乙蒜素在温室中对红掌细菌性叶斑病具有较好的防效,可应用到该病害的田间防治中;而农用链霉素由于防效极差,不建议再使用。

Abstract: In order to provide the basic information for control of anthura bacterial blight in Tianjin, inhibition and control effects of fungicides such as ethylicin on Xanthomonas axonopodis pv. dieffenbachiae causing anthura bacterial blight were studied. Virulence of ten fungicides against X. axonopodis pv. dieffenbachiae were tested with oxford cup method. The control effects of five fungicides on bacterial blight were tested by spray methods in this study. The results showed that 80% ethylicin EC showed the most prominent inhibit effect, its EC50 value was 1.511 4 mg/L. Secondly, 70% Carmazine WP, 6% primomycin WP, 90% new mycin WP and 3% mesophyllin WP showed obvious inhibit effect on X. axonopodis pv. dieffenbachiae, and their EC50 value were lower, respectively, 18.348 9, 60.232 1, 78.666 6 mg/L and 84.447 2 mg/L. The EC50 values of 46% Kocide WP, 20% thiediazole-copper SC and 30% copper succinate WP were all over 100 mg/L. The inhibit effects of 20% bismerthiazol WP and 72% agricultural streptomycin WP were the worst. Five fungicides were selected and tested for the greenhouse effects of anthura bacterial blight. The results showed: Ethylicin had the highest control effect, up to 76.1%, and agricultural streptomycin had the lowest control effect, only 27.1%. The control effects were as follows: ethylicin>primomycin>new mycin>copper succinate>agricultural streptomycin. Ethylicin can control anthura bacterial blight efficiently and can be applied on the disease management. However, agricultural streptomycin was not advised to usebecause of its poor control effect.
