摘要

#$%^&*AU2020101097A420200730.pdf#####ABSTRACT The present invention discloses a sustained-release tablet for controlling plant pathogenic nematodes, prepared by tableting from a mixture of chloroisobromine cyanuric acid, a plant 5 material with insecticidal and antibacterial activities, corn starch, ammonium carbamate, activated carbon, paraffin, straw particles or biogas residues, and the like. The tablet has a sustained release time of about 2 months, which is longer than that of chloroisobromine cyanuric acid diluted with water. Moreover, 79% to 90% of various nematodes can be controlled by the sustained-release tablet in field experiments. The tablets are buried in the soil in the manner of one tablet targeting 0 one individual plant to effectively protect the crop roots from nematodes. Since the tablets can be applied when seedlings are planted or transplanted, the operation is simple and convenient, and a lot of water and labor can be saved.
