Biocontrol of wilt disease of rice seedlings incited by Fusarium oxysporum through soil application of Streptomyces chilikensis RC1830

Abstract

Significance and Impact of the Study: This study focuses on the antifungal activity of novel Streptomyces chilikensis RC1830 and its application in the biocontrol of wilt diseases of rice seedlings by Fusarium oxysporum through soil application. Application of microbial cultures directly onto the agricultural sector as a biofertilizer is not so beneficial, so the strain RC1830 were formulated with several carrier materials for the production of portable and convenient form. The strain could be a potential development strategy as biofertilizer for economically important crops. A new whole-cell microbe-based bioformulation for plant growth promotion with antifungal properties was formulated with a shelf life of 3 months. Keywords antagonistic activity, plant growth-promoting traits, powder formulation, Streptomyces chilikensis, wilt disease of rice.

“…In addition, approximately 30% of diseases in all products are caused by these pathogens and they cause billions of dollars in quality losses worldwide every year (Shuping and Eloff 2017). The Fusarium genus includes many phytopathogen species that can significantly affect many crop yields (Behera et al, 2022). Fusarium species, which are among the most important phytopathogenic fungi in the world, attack a wide variety of crops such as wheat, barley, oats, rice, corn, legumes and vegetables such as potatoes, tomatoes, cucumbers, and cause various diseases such as head blight, root and crown rot and wilt (Leslie and Summerell 2008).…”
