INSECTICIDES AND FUNGICIDES 263 greatly diluted. But since it retains its active fungicide and bactericidalproperties even when very greatly diluted, and is not so dangerous a poisonin this condition as are corrosive sublimate and other antiseptic agents, itbecomes very useful in the hands of those who wish to disinfect quarters inwhich have been lodged people, or animals, affected with communicablediseases. The wash or spray of the dilute formalin has always seemed tothe writer much better for such uses than the fumes of formalin as generallyproduced. On plants the action of even dilute sprays is very quickly destructive,and I doubt if it has a value for their treatment. But for seed wheat,. Treating Grain with Formalin for Smut.^ likely to produce smutted heads and for potato scab it has proved veryconvenient and useful. A pint of the 40 per cent formalin may be pouredinto a barrel containing 30 gallons of water, stirred thoroughly, and thepotatoes in a sack can be set in the barrel for disinfection. They should beleft in the fluid for two hours and may then be removed and spread out ongrass or on a clean plank floor to dry, when another sack may be placedin the barrel. The treated potatoes must not be put in barrels or sacksthat have not been treated with the formalin. By having a number ofbarrels at hand, the work proceeds rapidly. Oats and wheat liable to smut may be treated by sprinkling the seedwith dilute formalin (1 pint in a barrel of water) until every seed is moist,not wet, then leaving for several hours in a heap, finally spreading outto dry. * Courtesy of H.
