Two boundaries are not the operator's to move. The first is chemical: this course prints no product names or doses, approvals change, and mushrooms are eaten fresh. Check the current label approval for mushrooms in India and your state advisory, and remember NHB's minimum 48 hour gap between spray and picking.
The second is the end of the crop. NHB records a cook out at 70 C held for 12 hours for pathogens, and 2 to 3 hours for insects, with spent compost buried under at least 10 cm of manure.
