Abstract

The invention relates to a root-knot nematode control agent as well as a preparing method and application thereof, belongs to the field of agriculture, and aims to solve the technical problem that a plant source root-knot nematode control agent as well as a preparing method and application thereof are provided. The root-knot nematode control agent provided by the invention has active constituents prepared from the following plant materials of Chinese herbal medicines in parts by weight: 1-8 parts of peganum harmala, 0-8 parts of folium ginkgo, 1-10 parts of sphora alopecuroide, 0-5 parts of radices sophorae subprostratae, 0-5 parts of rhizoma menispermi, 0-10 parts of radix sophorae flavescentis, 0-8 parts of castor beans, 1-10 parts of abutilon fibers, 0-8 parts of crown daisy and 0-5 parts of mandala. Meanwhile, the invention further discloses a preparing method and application of the root-knot nematode control agent. The root-knot nematode compound has the advantages of safety and nontoxicity, meanwhile can effectively prevent, restrain and kill root-knot nematodes.

Description

Technical field [0001] The invention relates to a root-knot nematode control agent, a preparation method and application thereof, and belongs to the field of agriculture. Background technique [0002] Root knot nematode disease is one of the main plant parasitic nematode diseases, which mainly damages many common vegetables such as cucumber, bitter gourd, tomato, eggplant, kidney bean, celery, spinach and so on. With the adjustment of the planting industry structure and the rapid expansion of the cultivation area of ​​vegetable protected fields, the occurrence of root-knot nematode disease has increased year by year, with a yield loss of 30% to 50%. Incidents of destroying seedlings and replanting occur from time to time. In addition, root-knot nematodes are harmful It also aggravated the occurrence of soil-borne fungal diseases such as fusarium wilt, root rot and some bacterial diseases, which has become a major obstacle to the current vegetable production. [0003] Chemical cont...
