摘要:

为探讨互生叶白千层提取物萜烯醇对番茄早疫病、草莓白粉病、葡萄白粉病的防治作用,本研究通过盆栽法和半田间试验,测定了萜烯醇对3种作物病原菌的毒力,并在四川开展2 a田间药效试验监测其防效。结果表明,萜烯醇对番茄早疫病、草莓白粉病、葡萄白粉病均具有较好的抑制作用,抑制中浓度(EC50)分别为17.1、27.6、10.1 µg/mL;9%萜烯醇乳油有效用量45~135 g/hm2防治番茄早疫病和草莓白粉病,有效用量90~180 mg/kg防治葡萄白粉病,最佳防效分别为86.0%、79.9%、84.9%,且对作物安全。田间高剂量萜烯醇防效与对照化学药剂80%代森锰锌可湿性粉剂、50%醚菌酯水分散粒剂差异不显著,显著优于4%嘧啶核苷类抗菌素水剂。植物源农药萜烯醇对3种作物病害具有较好的活性和田间防效,可大面积推广应用。

Abstract:

To study the control effects of terpenol extracted from Melaleuca alternifolia against tomato early blight, strawberry powdery mildew, and grape powdery mildew, the toxicity of terpenol against three crop disease was determined by pot method and semi-field experiment, and a 2-year field trial was investigated in Sichuan. The results showed that terpenol had good inhibitory effects on Alternaria solani, Sphaerotheca aphanis, Uncinula necator, with inhibitory medium concentrations (EC50) being 17.1, 27.6 and 10.1 µg/mL respectively. The dosage of 9% terpenol EC was 45-135 g/hm2 to control tomato early blight and strawberry powdery mildew, and the dosage was 90-180 mg/kg to control grape powdery mildew, optimal efficacies were 86.0%, 79.9% and 84.9% respectively, and it was safe for crops. Compared with the control fungicide of 80% mancozeb WP and 50% kresoxim-methy WG, there was no significant difference of efficacy from 9% terpenol EC with the highest dosage, and the efficacy was much better than 4% pyrimidine nucleoside antibiotic AS’s. The botanical pesticides terpenol have good activity and field control effect against three crop diseases and can be widely applied.
