What should you do if herbicide is accidentally mixed into oyster mushroom (Pleurotus ostreatus) substrate?

Herbicide should never be mixed into the substrate when growing oyster mushrooms. As for what adverse effects mixing herbicide into the substrate may have on the growth of oyster mushroom mycelium, we have not yet carried out experiments in this area. I think that mixing 50 grams of herbicide into 2000 jin of substrate is not a low concentration; even if it does not affect mycelial growth, at the very least herbicide residues will accumulate in the oyster mushroom fruiting bodies, making it very difficult to guarantee the safety and hygiene of the product. The solution is to repeatedly rinse the herbicide-containing substrate with water (5-6 times), then drain off some of the excess water, add an appropriate amount of carbendazim (reduced by about 20% from the original amount), pile it up for fermentation, and then use the original method for inoculation and cultivation.
