ICAR-DMR's 2011 manual and older folders list chemicals of their time, including some now banned in India. The dataset behind this site records a compost formulation containing BHC (lindane), an organochlorine no longer permitted. Formalin, carbendazim, malathion and dichlorvos appear throughout, each with its own regulatory and residue conditions today, and the manual and the Hindi folder disagree by a factor of ten on one insecticide dose.
Those documents stay valuable for causes, thresholds and process. Treat any chemical name in them as a historical record that must pass the label gate, and expect many will not. The practices that have not aged are physical: filters, screens, steam, cook-out, visit order and a diary.
