Abstract/Contents:Details an experiment in the use of chloropicrin as a form of weed control. Lists some of the advantages and disadvantages of the chemical. "The chloropicrin method of partially sterilizing soil has certain advantages over the common methods now in use. It requires no expensive equipment, which may be a distinct advantage in treating small lots of soil. Unlike the heat process of sterilization, chloropicrin has no harmful effect on the physical properties of the soil. The soil can be used soon after it has been treated with chloropicrin as then it will not be toxic but actually may be stimulating to grass. In one case when weeds were controlled completely grass seed germinated satisfactorily when planted only two days after the chemical was applied. Soil can be treated successfully with chloropicrin in piles or in turf without incurring the cost of moving the soil in and out of containers for treatments. [The disadvantages of chloropicrin are]: It requires careful covering of the treated soil to prevent escape of gas. As its effectiveness is decidedly reduced at low temperatures, it can not be used to advantage at all seasons. Heavy rates must be used to accomplish complete control of some of the most troublesome turf weeds. Where seed of the more resistant weeds are abundant in soil the cost of the treatment is high."
