Bacillus Megaterium

Yellow Powder

Improving soil fertility can decompose insoluble phosphorus and potassium in the soil and transform it into phosphorus and potassium compounds that can be absorbed by crops, increasing the supply of nutrients in the soil.Prevention and control of plant diseases has a strong inhibitory effect on cotton blight, wheat sheath blight, take-all, Pseudomonas solani, Fusarium wilt, Verticillium wilt, bacterial blight, and Fusarium root nodules.
