Embodiment 1

[0025] Weigh 100 kg of carbendazim, 50 kg of procymidone; 200 kg of potassium chlorate as an oxidizing agent, 150 kg of ammonium nitrate as a flame extinguishing agent, 20 kg of ammonium chloride as an extinguishing agent, 40 kg of talcum powder as a flame retardant, 400 kg of wood flour, and 40 kg of starch as an adhesive.

[0026] The procedure for preparing the aerosol is as follows:

[0027] First, fully dissolve potassium chlorate, sodium chloride, and ammonium nitrate in the mixing kettle with water, then add carbendazim and procymidone, stir evenly, and then add wood flour, adhesive starch, and flame retardant The talc powder is mixed and stirred evenly, and after being mechanically extruded into tablets (generally 25g / piece), dried and tested to pass the test, it can be packaged, stored and transported.

Embodiment 2

[0029] Take carbendazim 200kg, procymidone 100kg, potassium chlorate 200kg, ammonium nitrate 150kg, ammonium chloride 10kg, talcum powder 10kg, wood flour 300kg, fine starch 30kg.

[0030] The procedure for preparing the aerosol is as in Example 1.

[0031] The above-mentioned multi-rot aerosol products have been tested by the Tianjin Institute of Plant Protection for the control of Botrytis cinerea, with an effect of more than 90%.

Abstract

The invention provides a smoke agent and the preparing method. Said method comprises: dissolving carbendazol, rot fungi rihara and oxidant, combustion adjuvant, flame suppressor, wood flour, adhesive agent in water and mixing evenly, extruding with dry or wet method and shaping, drying at middle and low temperature and getting smoke agent. The product is mainly used to prevent gray mold for vegetable in the green house, it is non- toxic to environment and operating worker, and can reduce application cost.

Description

Technical field [0001] The invention belongs to a mixed smoke-type fungicide, in particular to a mixed smoke-type fungicide of carbendazim and procymidone and a preparation method thereof. Background technique [0002] The composition of carbendazim is: methyl benzimidazol-2-ylcarbamate; the composition of procymidone is: N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1 , 2-Dicarbonylimine. Both are fungicides commonly used in agriculture, and they become multi-rot fungicides after compounding, and can better enhance the fungicide effect. Due to the multi-rot compound wettable powder produced at present, it cannot be used for spraying smog, but needs to be mixed with a large amount of water spray. Like this, not only increases the humidity of greenhouse, promotes the growth of pathogenic bacteria, is unfavorable for the prevention and control of disease; And conventional water mist, uses in greenhouse vegetable, needs to add water more than 100Kg / acre about, wasted a larg...
