Extract

The literature does not reveal any direct information concerning the time of exposure or concentration required of a soil fumigant to kill weed seeds. For specific soils and conditions the appropriate rate of application may be known but this does not represent an actual toxic concentration. This is due to the fact that the toxicity of the fumigant may be decreased due to adsorption of the fumigant by the soil or solution in the soil water. This investigation was carried out to determine what concentration of fumigant is needed for a specific time to produce a given percent control of dormant imbibed seeds.
