- 摘要:
- :通过对峙培养等方法分离筛选出对辣椒疫霉菌有效拮抗的木霉菌株,进行了辣椒疫病的盆栽防病试验。结果表明:木霉(Trichoderma spp.)TC株系对辣椒疫霉(Phytophthora capsic)引起的辣椒疫病有良好的防治效果。对峙培养和木霉菌挥发性代谢物质抑菌活性测定试验中对辣椒疫霉菌都有非常好的抑制作用,抑制率分别可达到75%和70%。盆栽试验结果表明,先浇灌接种孢子悬浮液后60 d接种辣椒疫霉,对疫病的防治效果可达73.7%。将木霉TC与15%甲霜灵1 000倍协同作用防治辣椒疫病时,可达82.5%,防效比单独使用木霉或甲霜灵要好。二者表现出较好的协同防治作用
- Abstract:
- Effectively antergic Trichoderma spp.on pepper Phytophthora capsic was separated by confrontation culture and disease control was experimented in pots.The results showed that pepper blight caused byPhytophthora capsic could be efficiently controlled by Trichoderma spp.TC.The suppression ratios of pepper P.capsic after confrontation culturing and volatile metabolites inhibitory test were all very well,which respectively reached 75% and 70%.The results of pot experiment showed the best control appeared when inoculated pepper Phytophthora capsic 60 d after watering with spore suspensions,which reached 73.7%.The results reached 82.5% when mixing Trichoderma spp.TC with 1 000 folds of Phytophthora capsic. Synergetic effect showed when applying the mixture,which were much better than applying either Trichoderma spp.TC or Phytophthora capsic alone.
