Characterization of Antagonistic Bacillus methylotrophicus Isolated From Rhizosphere and Its Biocontrol Effects on Maize Stalk Rot

Abstract: Stalk rot is one of the most serious and widespread diseases in maize, and effective control measures are currently lacking. Therefore, this study aimed to develop a new biological agent to manage this disease. An antagonistic bacterial strain, TA-1, was isolated from rhizosphere soil and identified as Bacillus methylotrophicus based on morphological and biochemical characterization and 16S ribosomal RNA and gyrB gene sequence analyses. TA-1 exhibited a strong antifungal effect on the growth of Fusarium gramin… Show more

“…The control group was sprayed with equal volumes of distilled water. Finally, the potato plants (35 days-old) were harvested to analyze the growth status including the plant height (PH), main stem diameter (MSD), and main roots number (MRN) ( Wang, 2018 ; Cheng et al, 2019 ). In addition, after 80 days of growth, plants within each treatment group were harvested to record the average per plant yield (PPY) ( Caulier et al, 2018 ).…”

“…B. velezensis has been used in the biocontrol of both wheat, powdery mildew by Blumeria granminis and Wilt Disease Fusarium oxysporium [35]. Recently, Cheng et al (2019) reported that B. methylotrophicus showed efficacy on the management of Maize stalk rot [36]. But there have not been any reports on biocontrol of B. siamensis and B. methylotrophicus in black pepper.…”

“…The continuous use of chemical agents for biological control by crop growers, coupled with their lack of understanding of the mechanism of inhibition by these agents, has contributed to worldwide concerns regarding the use of chemical control of pathogens [ 23 ]. In addition, the successful use of a biocontrol agent depends upon being familiar with the biological environment in which the agent is to be used and the production of a stable formulation of the selected biocontrol agent.…”
