Use 1 liter per 25m3volume of space (40 fl oz. / 1000 ft3)
Formalin in the ratio of three parts formalin to two parts of potassium permanganate. Because of the violent chemical reaction, never use more than 1.2 liters (2 pints) of formalin in any one container
An application rate of 53 ml formalin and 35 g potassium permanganate per m3of
space is recommended. These amounts are effective in fumigation for 20 min the
recommended temperature and humidity. To calculate the amounts of chemicals
necessary, the internal dimensions (i.e. length x width x height) of the incubator,
fumigation cabinet or fumigation room should be measured. The space occupied by trays of eggs or articles to be fumigated need not be taken into consideration.
With respect to all , use1.35ml of 40% formalin solution and 0.84g potassium permanganate per cubic foot . or you can use 35ml formalin 40% and 17.5 g potassium permanganate
