Problems solved by technology

In addition, although domestic pesticide manufacturers produce carbendazim and procymidone or mixed wettable powders of carbendazim and diethofencarb, these preparations cannot be sprayed with a fog machine, but can only be sprayed with a large amount of water.
Because spraying water mist increases the humidity in the greenhouse, which promotes the growth and development of germs, which is not conducive to disease control, so users are reluctant to use this type of preparation

Embodiment 1

[0026] Take benzimidazole-2-methyl carbamate and N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-diformyl imide 80%:20% 5% of multi-rot mixture, 30% of compound surfactant composed of 50% of Nongru No. 500 and 50% of OP-7, 55% of diluent composed of 95% of aromatic hydrocarbon No. 2 and 5% of liquid paraffin, antifreeze Agent ethylene glycol 10%. First add the diluent and antifreeze into a mixing tank, add the multi-rot mixture under stirring, and then add the composite surfactant, pulverize it through the colloid mill under stirring, and pass the suspension after the colloid mill , and then go through an ultrafine pulverizer - LMZ type horizontal sand mill to crush repeatedly until the particle size of the solid particles is ≤ 2 μm, and finally analyze and detect the specified indicators of the suspension, and the qualified hot fog formulation control Botrytis cinerea multi-rot fungicide products are packaged, stored and transported.

Embodiment 2

[0028]Take benzimidazole-2-carbamate methyl ester and 3,4-diethoxyphenylcarbamate isopropyl ester 50%: 50% of the multi-ethyl mixture 5% of the composition, other steps are the same as in Example 1, and obtain Hot mist type control Botrytis Botrytis Bacteria fungicide products.

Embodiment 3

[0030] Take benzimidazole-2-methyl carbamate and N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-diformyl imide 80%:20% Multi-rot mixture composed of 15%, Nongru No. 500 40% and OP-4 No. 40% and EL-40, 20% composite surfactant 20%, aromatic hydrocarbon No. 2 60% and liquid paraffin 3% and o 30% of dichlorobenzene and 7% of white oil are configured into 57% of diluent and 8% of antifreeze propylene glycol. First add the diluent and antifreeze into a mixing tank, add the multi-rot mixture under stirring, and then add the composite surfactant, pulverize it through the colloid mill under stirring, and pass the suspension after the colloid mill , and then go through an ultrafine pulverizer - LMZ type horizontal sand mill to sand and grind back and forth until the particle size of the solid particles is ≤ 2 μm, and finally analyze and detect the specified indicators of the suspension, and the hot mist dosage form after passing the test The fungicide products for the prevention ...

Abstract

The present invention relates to a hot fogging agent (generally, also called smoking agent) fungicide for controlling grey mould of greenhouse vegetables and its preparation method and its application. It is formed from fungicide main component A, surfactant B, high boiling point diluent C and antifreezing agent D, in which their weight percentage is: A:B:C:D=5-40%:0.1-30%:20-80%:0.1-10%, and theA is the mixture of carbendazim (80%) and procymidone (20%) or the mixture of carbendazim (50%) and diethofencarb (50%). The grain size of said invented product solid particles is less than or equal to 2 micro meters.

Description

Technical field [0001] The technical solution claimed in the present invention relates to a biocide characterized by the thermal spray method, specifically for preventing gray mold of vegetables in greenhouses, and the main active ingredient is benzimidazole-2-carbamic acid methyl Ester (commonly known as carbendazim) and N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarboximide (commonly known as procymidone) or the main medicinal effect The ingredients are benzimidazole-2-methyl carbamate and 3,4-diethoxyphenyl carbamate isopropyl (commonly known as Dimethocarb) type fungicide and its Methods of preparation and methods of use. Background technique [0002] Although there are many documents on fungicide pesticides used to prevent and control vegetable gray mold, CN1091897A and CN1288663A also disclose the control vegetable gray mold containing a certain amount of carbendazim (i.e. benzimidazole-2-methyl carbamate). The compound fungicides used for disease, however...
