<p>Clubroot is a major disease that often infects cabbage caused by Plasmodiophora brassicae Wor.. The leaf of T. diversifolia is an example of weeds that can be used as green leaf manure. The research aimed to study the effectiveness and dosage of green manure from Tithonia leaf to control clubroot. In planta test was conducted by using factorial completely randomized design, the first factor was dosages of Tithonia green manure and second factor was application time of fertilizing. The research showed that green manure from Tithonia leaf effectively suppressed infection of P. brassicae and was capable of increasing growth variable of cabbage seedling. Fertilizing with green leaf manure of Tithonia with dosage of 10 ton ha<sup>-1</sup> could decreased intensity of P. brassicae infection up to 10,18%. The application time of fertilizing 0 days after planting has the highest weight of cabbage seedling biomass is 14,10 g.</p>
The research was conducted to study binucleate Rhizoctonia as biocontrol agents again <em>Sclerotium rolfsii </em>Sacc. On soybean seedlings in Laboratory and greenhouse. Nine of 57 isolates were identified as binucleate Rhizoctonia. Eight of the nine isolates were non pathogenic and three of them were used in the research as biocontrol agents. The three isolate decreased the disease intensity caused by <em>S. Rolfsii </em>in the greenhouse by 29,17; 14,58 and 41,67%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
