A Review on Symptomatology, Epidemiology and Integrated Management Strategies of Some Economically Important Fungal Diseases of Soybean (Glycine max)

Abstract

Among different production constraints in soybean, the most serious being diseases. These diseases are caused principally by fungi or bacteria however fungal diseases causing greater threat to the crop production. The damage caused by foliar diseases is mostly of minor importance except diseases like soybean rust, Pod blight, Rhizoctonia aerial blight or web blight etc. which can reduce yields when weather conditions favor disease development. Correct identification and early detection are critical in the proper management of soybean diseases. In this review we are discussing about economic importance, symptomatology, causal organism, disease cycle, epidemiology and integrated management of some economically important fungal diseases of soybean viz. Seed and seedling diseases of soybean, Rhizoctonia root rot, Pod blight, Rhizoctonia aerial blight or web blight, Charocal rot, Rust disease and collar rot. K e y w o r d s Soybean diseases, seed and seedling diseases of soybean, Rhizoctonia root rot, Pod blight, Rhizoctonia aerial blight/ web blight, Charocal rot, Rust disease and collar rot

Determinants of Farmers’ Perception and Adoption of Improved Legume Varieties Among Farming Households in Northern Nigeria

“…Note that the majority of legume farmers in the dataset were mainly soybean farmers. With this knowledge in mind, the finding is consistent with the view that soybean is regarded by many as "poor man's meat" given that it is the cheapest source of protein (Patel et al, 2016;Sutar et al, 2019;Borah & Deb, 2020). The negative effect of women land ownership on the decision to adopt ILV implied that women who were owners of land were less likely than their counterparts to adopt ILV, which is contrary to the a priori expectation.…”

“…These diseases are caused principally by bacteria and fungi, but the latter cause more significant losses in agrarian production. Typically, the foliar disease damage is less important, except for diseases like soybean rust, Pod blight, Rhizoctonia aerial blight or web blight, etc., which can cause severe losses when the weather conditions stimulate disease development …”

“…Charcoal rot on soybean is one of the deadliest diseases affecting this crop, caused by Macrophomina phaseolina (Tassi) Goidanich, a fungal pathogen hosted by about 500 cultivated and wild plants . To better understand the negative impact of M.…”

“…Typically, the foliar disease damage is less important, except for diseases like soybean rust, Pod blight, Rhizoctonia aerial blight or web blight, etc., which can cause severe losses when the weather conditions stimulate disease development. 9 Charcoal rot on soybean is one of the deadliest diseases affecting this crop, caused by Macrophomina phaseolina (Tassi) Goidanich, 9 a fungal pathogen hosted by about 500 cultivated and wild plants. 10 To better understand the negative impact of M. phaseolina on soybean yield production, complex biology and genetic studies were carried out.…”
