Problems solved by technology

The production of sodium cyanogen carbonate fertilizer has been stopped in the country. Ammonia water is produced by some domestic small factories, and the quality is unstable. In addition, a large amount of ammonia gas is released during the production process, which affects the health of employees and does not meet the relevant regulations on environmental protection; therefore, a kind of Safe, environmentally friendly, low-toxic fungicides are used in the prevention and treatment of kiwifruit, citrus, and vegetable cankers instead of conventional copper ammonia water

Embodiment 1

[0029]Embodiment 1: a kind of fungicide that is used to prevent and treat plant canker, comprises the chelate of aminoalcohol compound and copper salt, pH adjuster, water;

[0030] The chemical formula of the amino alcohol compound is: NH 2 (CH 2 ) nOH; where, 2≤n≤5;

[0031] The preferred monoethanolamine of the aminoalcohol compound;

[0032] The copper salt is one of copper sulfate, copper nitrate or copper acetate; the pH regulator is citric acid;

[0033] The present invention selects aminoalcohol compound and copper salt to carry out complexation, because there are nitrogen atom and oxygen atom in the molecule of aminoalcohol compound, so have the chemical property of amine and alcohol concurrently, can combine with Cu 2+ The ions form a stable chelate compound, so that the product contains a large amount of complexed Cu 2+ ions, through complexed Cu 2+ Ions and K on the cell membrane surface of pathogenic bacteria ＋ 、H ＋ Wait for cation exchange to coagulate the ...

Embodiment 2

[0046] Embodiment 2: a kind of fungicide that is used to prevent and treat plant canker, comprises the chelate of aminoalcohol compound and copper salt, pH adjuster, water;

[0047] The chemical formula of the amino alcohol compound is: NH 2 (CH 2 ) nOH; where, 2≤n≤5;

[0048] The preferred monoethanolamine of the aminoalcohol compound;

[0049] It is prepared by the following method: in the reaction kettle, according to the parts by weight, add 5 parts of copper salt, 5 parts of monoethanolamine, 4 parts of citric acid and 86 parts of water for complexation reaction;

[0050] The copper salt is copper sulfate; the pH regulator is edible citric acid;

[0051] The complexation reaction temperature is 40°C;

[0052] The reaction kettle is a 1000 liter enamel reaction kettle.

Embodiment 3

[0053] Embodiment 3: a kind of fungicide that is used to control plant canker, comprises the chelate of aminoalcohol compound and copper salt, pH adjuster, water;

Abstract

The invention discloses a bactericide for preventing and treating plant canker. The bactericide comprises a chelate of an amino alcohol compound and a copper salt, a pH regulator and water. The invention has the following beneficial effects: the invention uses the chelate of the amino alcohol compound and the copper salt as the effective bactericidal component of the bactericide, so that the invention has prominent characteristics, preferably, the chelate of monoethanolamine and the copper salt is selected, and the chemical formula of the chelate is [Cu (H2NCH2CH2OH) 4] < 2 + >; from the perspective of complexing and chelating of the bivalent copper ions, the chelating or complexing degree of monoethanolamine to the bivalent copper ions is large, the concentration of free Cu < 2 + > ions is lower than that of cuaminosulfate, the concentration of complexed Cu < 2 + > ions is higher, the relative molecular mass of the prepared chelate is larger than that of cuaminosulfate, the dilution multiple is increased to 500-800 times when crop diseases are prevented and treated, and the dosage per mu is reduced by 60%.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a fungicide for preventing and treating plant canker and its application method. Background technique [0002] Kiwifruit is a berry-like leafy vine fruit tree. It belongs to Actinidiaceae in classification and is suitable for growing in a warm and humid environment. Therefore, it is rich in nutrients, sweet and sour, and is known as the "king of fruits". my country is the origin of kiwifruit and has rich Kiwifruit germplasm resources, but also a major producer of kiwifruit. According to statistics from the plant protection department in 2018, the harvested area of ​​kiwifruit in my country is 168,500 mu, more than two-thirds of the world's total harvested area, and the output is about 2.03 million tons, accounting for about one-half of the world's total output. The provinces with larger planting areas are Shaanxi with 77,000 mu, Sichuan with 46,000 mu, Guizhou with 29,000 mu...
