Excerpt from Soil Fumigation for Control of Nematodes and Other Soil-Inhabiting Organisms
The.most effective chemicals are those that, through volatilization or chemical reaction, give off toxic fumes which diffuse through the soil. Because the fumes diffuse to only a Short distance from.the point of application, volatile liquids_are injected into the soil at closely spaced intervals. Solids usually are applied in powdered or granular fgrm.and.mixed with.the soil mechanically. Chemicals capable of killing such soil-borne organisms as nematodes, fungi, insects,and weed seeds are very likely to injure the roots of plants, hence fumi gants are applied before the crop is planted, and an interval must elapse between application and planting a: allow time for the chemi cals to lose their toxic properties or fer the fumes to escape into the air.
