Abstract

Eight kinds of extracts of Chinese medicinal herbs and their mixtures were used to screen out effective Chinese medicinal herbs for controlling downy mildew of organic lettuce.The results showed that,the eight kinds of Chinese medicinal herb extracts and their mixtures showed significantly better inhibition effects on the germination of lettuce downy mildew spores and incidence of downy mildew in field than the control treatment.And the mixtures did better than single Chinese medicinal herb on inhibiting the germination of downy mildew spores and the incidence of downy mildew in field.The mixture Andrographis paniculata∶Magnolia officinalis∶burdock=2∶1∶1 did best on inhibiting spore germination and possessed the best prevention effect on lettuce downy mildew in seedling stage,while the mixture A.paniculata ∶M.officinalis∶burdock=1∶1∶2 had best treatment effect on lettuce downy mildew in seedling stage.
