Abstract

The invention provides an athomin (comprising main active materials of Allylisothiocynate, AITC for short) capsule, which comprises a capsule core and a capsule shell, wherein the capsule core contains the athomin; and the capsule shell contains water soluble colloid, glycerin and water. The athomin capsule can be used for fumigating and sterilization of soil, not only keeps the good activities of the athomin for killing nematodes and inhibiting bacterial, but also can well stop strong offensive odor of the athomin, thereby reducing the hazard of the athomin to people applying pesticide; in addition, the athomin capsule is more convenient to use, and does not pollute the environment.

Description

technical field [0001] The invention relates to a horseradish capsule for fumigation and disinfection of soil, in particular to the horseradish essential oil extracted from the cruciferous horseradish plant, wherein the main active substance is allyl isothiocyanate (Allyl isothiocynate (AITC for short), a capsule prepared from water-soluble colloids such as gelatin as the outer wall material. Background technique [0002] Horseradish is an active substance extracted from horseradish plant (Cochlearia armoracia.), and its main component is allyl isothiocyanate (AITC). It has long been found that AITC has strong antibacterial activity and is often used as a preservative in the food processing industry. In recent years, studies have reported that AITC also has the function of attracting Braconis rapae, and can also make some insects or nematodes escape away. This finding shows that it has a good prospect for agricultural use. In the United States, a binary compound pesticide ...
