[0019]Water (27.5%), PBTC (17.5%) and hydrochloric acid (HCl) (55%) were admixed to form a first solution. Water (85%) and sodium chlorite (15%) were admixed to form a second solution. The first and second solutions were combined to form a combined solution. Sufficient contact time was allowed in the mixing vessel 12 to convert a substantial portion of the sodium chlorite solution into chlorine dioxide. The combined solution can also be referred to as chlorine dioxide. For test purposes, five soil beds were prepared. These beds were covered with sheet plastic. In the first bed, 150 ppm of chlorine dioxide was added irrigation water and the mixture was introduced to the soil bed until the soil bed was saturated. In the second soil bed, 350 ppm of chlorine dioxide was added to irrigation water and the mixture was introduced into the second soil bed until the second soil bed was saturated. The third soil bed received 750 ppm of chlorine dioxide in irrigation water until that bed was sa...

Abstract

Introducing chlorine dioxide solution into an agricultural soil in an amount effective to suspend weed and pathogen growth in the soil. The chlorine dioxide is allowed to decompose in the soil. Then, a crop is planted in the treated soil. The decomposed chlorine dioxide provides nutrients for the crops as they grow.

Description

TECHNICAL FIELD[0001]This invention relates to a method of suspending weed and pathogen growth in soil prior to growing a crop in the soil. More particularly, it relates a method of introducing chlorine dioxide into the soil in an amount sufficient to suspend weed and pathogen growth and then planting and growing a crop in the treated soil.BACKGROUND OF THE INVENTION[0002]It is known to treat plant growing soil with fumigants to prevent the harmful effects of invasive weeds and other unwanted vegetation and pathogens. If allowed to grow, these invasive plants would compete with the agricultural crops for water, minerals and sunlight. They would increase stresses from nematodes, insects and disease, and adversely effect product quality. Also, harvest effacy is diminished due to pickers inability to find and pick produce in weedy growth. Unwanted vegetation increases production costs by adding control costs up to several hundred dollars per acre.[0003]Methyl-bromide (M-b) has been the...
