Use: Biochemical studies Jinggangmycin suction effect is very strong agricultural antibiotics, when Rhizoctonia hyphae contact Jinggangmycin, bacterial cells can be quickly absorbed by the body and bacteria conduction disturbances and. inhibition of bacterial cell normal growth and development, and thus play a therapeutic role. Jinggangmycin also be used to prevent wheat sheath blight, smut and vegetables such as root rot.
