Embodiment 1

[0017] Test drug

[0018] 99.8% cyanodinitrile (Jiangsu Nantong Strong Chemical Co., Ltd.).

[0019] Soil sample for test

[0020] Soil samples were collected in protected areas in Beijing, where nematodes and diseases are serious all the year round, and the soil from the plow layer was taken and passed through a 2mm sieve, and mixed well for later use. After analysis, the soil water content is 18.76%, pH6.48, soil organic matter content is 4.5%, NH 4+ -N 18.1mg / kg, NO 3- -N 118.8mg / kg, available phosphorus 552.8mg / kg, available potassium 666.1mg / kg, belonging to sandy loam.

[0021] Evaluation Indicators and Methods

[0022] Meloidogyne incognita, using centrifugation method (Liu Weizhi, 2000);

[0023] Fusarium fusatus, isolated by the Komada method;

[0024] Phytophthora nobita, separated by the Masago method;

[0025] Verticillium chlamydia, isolated by the Komada method;

[0026] Pythium oligandrum, isolated by the Komada method;

[0027] cat's eye grass, measure...

Embodiment 2

[0101] The cyanoethanedinitrile preparation is composed of the following components by weight: 15 parts of cyanoethanedinitrile, 25 parts of Tween-20, 5 parts of polyvinyl alcohol, 5 parts of cyclodextrin, and 50 parts of water.

[0102] Before cucumber planting, the soil was first plowed 30cm deep, while ensuring that the soil had a certain humidity, and then the above-mentioned cyanonitrile preparation (according to the active ingredient 10g / m 2 The dosage) mixed soil application, using the "reverse burial method" film-covered fumigation for 2 weeks, open air for 3 days, after qualitatively judging that there is no pesticide residue through the cucumber seed germination experiment, it can be planted.

Embodiment 3

[0104] The cyanoethanedinitrile preparation is composed of the following components by weight: 15 parts of cyanoethanedinitrile, 20 parts of agricultural milk 300#, 15 parts of carboxymethyl cellulose, and 30 parts of water.

[0105] Before the coriander is planted, at first the soil is deeply plowed by 30cm, and the soil has a certain humidity while ensuring that the above-mentioned cyanoethanedinitrile preparation (according to the active ingredient 10g / m 2 The dosage) mixed soil application, using the "reverse burial method" to fumigate for 2 weeks, open air for 3 days, and after qualitatively judging that there is no chemical residue through the germination experiment of coriander seeds, it can be planted.

Abstract

The invention discloses a composition for preventing and treating root-knot nematodes, soil-borne pathogenic fungi and weeds. The composition is mixed with an emulsifier, an excipient, a filling agent and water to be used as a pesticide for effective prevention and treatment of soil-borne diseases and the weeds. The composition can effectively kill harmful pathogenic bacteria and nematodes in soil, can inhibit weed germination and growth, is used for pre-planting soil disinfection for preventing and treating vegetables, strawberries, flowers, melons, seedling nursery, orchards, tea gardens, vineyards, trees, Chinese herbal medicines and other crop fields, and effectively prevents the root-knot nematodes, main soil-borne pathogenic fungi, main gramineae and broadleaf weeds and the like.

Description

technical field [0001] The invention relates to a composition for preventing and controlling soil-borne diseases, in particular to a composition for controlling root-knot nematodes, soil-borne pathogenic fungi and weeds. Background technique [0002] In the past ten years, with the adjustment of agricultural planting structure, protected cultivation has developed rapidly in our country. The national protected area has exceeded 2 million hectares. As an important agricultural measure to increase farmers' income and transform from traditional agriculture to modern agriculture, protected cultivation in China will continue to develop in the future, and the crops cultivated will also change from the current vegetables and strawberries to flowers, melons, and fruit trees. , Nursery, Chinese herbal medicine and other directions. The development of protected areas also provides a suitable environment for the occurrence and development of root-knot nematodes, soil-borne diseases an...
