- 摘要:
- 1 000亿/g枯草芽孢杆菌WP、300亿/g蜡质芽孢杆菌WP(益微)、10%苯醚甲环唑WG、10%戊菌唑EC、200亿/g木霉菌WP、2亿/g木霉菌WG、300亿/g蜡质芽孢杆菌WP(克斑定)、50%菌核净WP、25%丙环唑EC、0.5%大黄素甲醚AS抑菌效果较好。其EC50≤0.05 mg/L,EC90<5.0 mg/L。不同药剂配比中,具有增效作用的配比有46 个,300亿/g 蜡质芽孢杆菌 WP(益微)+95%菌核净TC 3∶1增效作用最为明显,其共毒系数为988.54。该研究筛选出了对人参菌核病菌毒力较高的药剂及配比,对人参菌核病的安全高效防治具有重要意义。
- Abstract:
- Toxicities of 27 fungicides and 69 proportions of 9 fungicides against S.schinseng were tested by mycelium growth rate method in laboratory.The results showed that the inhibitory effect of bacillus subtilis 100 billion/g WP,bacillus cereus 30 billion/g WP(Yiwei),difenoconazole 10% WG,penconazole 10% EC,trichoderma 20 billion/g WP,trichoderma 0.2 billion/g WG,bacillus cereus 30 billion/g WP(Kebanding),dimethachlon 50% WP,propiconazole 25% EC,physcion 0.5% AS was better.Their EC50 values were lower than 0.05 mg/L,EC90 values were lower than 5.0 mg/L.In different proportions,46 proportions had synergistic action,the most obvious synergistic action was bacillus cereus 30 billion/g WP(Yiwei)+dimethachlon 95% TC 3∶1,the CTC was 988.54.Effective fungicides and proportions were screened out,which had important significance to fungicides control the disease safely and efficiently.
