Fungicide toxicity against the growth of lineages of the fungus Metarhizium anisopliae var. anisopliae (Mestch.) Sorokin

In this work, the fungicidal action of three agrochemicals (Sphere®, Nativo® and Bendazol®) used in soybean for control of fungal diseases on the lineages CG-28 and CG-30 of Metarhizium anisopliae var. anisopliae was evaluated. It was found that the fungicides inhibited the vegetative growth of the lineages at the concentrations indicated for the field, thereby showing its antifungal...

The research of infection process and biological characteristics of Rhizoctonia solani AG-1 IB on soybean

The isolate Rhizoctonia solani AG-1 IB collected from the diseased leaves of soybean were identified by the method of internal transcribed spacer sequence analysis. In this study, we focus on the biological characteristics and infection process of AG-1IB. Morphological, nucleus, chromosome, and infection process were observed. Typical infectious structures as infection cushion and appressorium were observed...
