ABSTRACT:
An apparatus for introducing a fumigant into the soil so as to provide a sterilized system which is essentially free of weed seeds, insects, nematodes and fungi including pathogenic and saprophytic bacteria and such other micro-organisms as may interfere with the growth of desirable vegetative forms. The apparatus consists of a horizontally disposed tubular structure which receives the fumigant under pressure in discrete quantities for controlled release. The apparatus is easily extensible and may be adapted to cover soil areas of any desired size.
