We do not recommend direct tank mixing of YM-BS-L01 with strong chemical fungicides, broad-spectrum biocides, chlorinated compounds or disinfectants (e.g. copper-based fungicides, quaternary ammonium compounds, sodium hypochlorite). These substances will inactivate live Bacillus subtilis cells and reduce microbial colonisation performance.

That said, YM-BS-L01 contains abundant antimicrobial metabolites produced during fermentation — including iturin, surfactin and fengycin. These bioactive lipopeptides are chemically stable and retain full disease-suppressing activity even if bacterial cells are partially inactivated.

For field practice, an interval application strategy is recommended: apply chemical fungicides first, then apply YM-BS-L01 2–3 days later. This combines the fast-acting effect of chemical treatment with the long-term biological protection and growth-promoting effect of the microbial agent, achieving better overall control.

• For low-dose selective fungicides or soluble NPK fertilisers, mixing is generally acceptable. Always add YM-BS-L01 last, and conduct a small-scale compatibility test before large-scale application.

• YM-CMF-G01 and YM-EOF-G01 can be used alongside most chemical fertilisers. Avoid direct mixing with highly alkaline materials or concentrated fungicides.

• Organic supplements such as brown sugar, molasses and protein sources are beneficial during the microbial propagation stage.

Only if unchlorinated, or if chlorine has been allowed to dissipate. Leave tap water uncovered for at least 2–4 hours before use, or use rainwater, well water or river water. Chlorinated municipal water is one of the most common causes of reduced microbial product efficacy.

Generally yes, as long as the other products do not contain broad-spectrum antimicrobial agents or chemical disinfectants. Combining with complementary biologicals (e.g., Trichoderma products, mycorrhizal inoculants) can enhance overall performance. Always conduct a small-scale compatibility test before large-scale mixing.
