Embodiment 1

[0025] Ethylene-1,2-bis(dithiocarbamate) manganese and zinc coordination complex is also known as mancozeb, 1-(2-cyano-2-methoxyimino)-3- Ethyl urea, also known as cymoxanil or manganese zinc cymoxanil, is the active ingredient of manganese zinc cymoxanil aerosol.

[0026] Raw material formula: mancozeb and cymoxanil 40%;

[0027] Complex surfactant 30%;

[0028] Thinner 21%;

[0029] Antifreeze 9%;

[0030] All the above are percentages by weight.

[0031] That is, weigh 320Kg of ethylene-1,2-bis(dithiocarbamate) manganese and zinc coordination complex, also known as mancozeb, 1-(2-cyano-2-methoxyimino )-3-Ethylurea is also known as cymoxanil 80Kg; composite surfactant Nongru No. 500 150Kg, OP-4 30Kg, Nongru No. 600 60Kg, Nongru No. 700 20Kg, JFC40Kg, diluent aromatic hydrocarbon No. 2 70Kg, white oil 40Kg, o-dichlorobenzene 80Kg, diethylene glycol 20Kg, antifreeze agent ethylene glycol 90Kg.

[0032] Preparation method: Mix manco...

Embodiment 2

[0036] Raw material formula: mancozeb and cymoxanil 18%;

[0037] Complex surfactant 8%;

[0038] Thinner 73%;

[0039] Antifreeze 1%;

[0040] All the above are percentages by weight.

[0041] Namely take 145Kg of ethylene-1,2-bis(dithiocarbamate) manganese and zinc coordination complex, also known as mancozeb, 1-(2-cyano-2-methoxyimino )-3-Ethylurea is also known as cymoxanil 35Kg; compound surfactant Nongru No. 500 50Kg, span-80 20Kg, JFC 10Kg; diluent triethylene glycol 730Kg, antifreeze agent ethylene glycol 10Kg.

[0042] Its preparation method is with embodiment 1.

Embodiment 3

[0044] Raw material formula: mancozeb and cymoxanil 25%;

[0045] Complex surfactant 10%;

[0046] Thinner 63%;

[0047] Antifreeze 2%;

[0048] All the above are percentages by weight.

[0049] Namely take 200Kg of ethylene-1,2-bis(dithiocarbamate) manganese and zinc coordination complex, also known as mancozeb, 1-(2-cyano-2-methoxyimino )-3-Ethylurea is also known as cymoxanil 50Kg; compound surfactant Nongru No. 500 30Kg, Nongru No. 600 20Kg, EL-40, 20Kg, Dispers 710 30Kg; diluent aromatic hydrocarbon No. 2 290Kg, triethylene glycol 240Kg, o-dichlorobenzene 100Kg, antifreeze propylene glycol 20Kg.

[0050] Its preparation method is with embodiment 1.

Abstract

The present invention relates to a smoking agent for controlling downy mildew of vegetable, specially for controlling downy mildew of greenhouse vegetable. Its composition includes mancozeb, cymoxanid, diluent, antifreezing agent and compound surfactant. Its preparation method includes the following steps: mixing mancozeb and cymoxanial together, using several surfactants, and adopting ultramicropulverizing process and making them disperse and suspended in the high boiling point diluent so as to obtain the invented product.

Description

technical field [0001] The invention belongs to a mixed aerosol-type bactericide, in particular to a mixed aerosol-type bactericide of mancozeb and cymoxanil and a preparation method thereof. technical background [0002] Manganese zinc · frost urea is a fungicide, its main features are: synergistic. However, the mixed wettable powder of manganese zinc and cream urea currently produced cannot be used to spray smoke, but needs to be mixed with a large amount of water to spray water mist. Like this, not only greatly increase the humidity of greenhouse, promote the growth of pathogenic bacteria, be unfavorable for the prevention and control of disease; And conventional water mist, use in greenhouse vegetables, need to add water more than 200Kg / mu of water about, wasted a large amount of fresh water; When water mist sprays tall and densely planted crops, it will seriously harm the operators, and it is not resistant to rain erosion, and the control effect is low. In addition, a...
