在实验室筛选防治南美叶疫病杀菌剂的研究中,发现涂有杀菌剂的纤维素膜是一种适宜的琼脂培养基的替代品。它显示了与试药剂的杀菌、抑菌效应和残效。经喷施杀菌剂和用病菌分生孢子接种后的橡胶嫩叶叶圆片也能很好测定出杀菌剂的防效及治疗性能。本试验比较用百菌清、代森锰锌、三唑二甲酮、环吗啉、二噻农、苯菌灵、嗪胺灵、多菌灵和甲基托布津防治南美叶疫病的效果和性能。 In the laboratory screening of fungicides against the leaf blight of South America, it was found that the fungicide coated cellulose film was a suitable alternative to agar medium. It shows the bactericidal, bacteriostatic and residual effects with the test agents. After spraying fungicides and bacteria inoculated with conidia after the leaves of young rubber leaves can also be a good measure of the antimicrobial efficacy and therapeutic properties. This experiment compared the efficacy of chlorothalonil, mancozeb, triadimefon, cycloporphyrin, dithianon, benomyl, azinamide, carbendazim and thiophanatelate in the control of leaf blight in South America and performance.
