The Effects of Soil Sterilant Chemicals on the Germination and Development of Conifer Seedlings and Weed Control

Numerous chemicals that can be used as soil fumigants1 have been placed on the market during the last few years. These chemicals when applied from a few days to a month before sowing kill most of the weed seeds, insects, fungi, and nematodes in the soil, yet lose their toxicity in a short time.
