Abstract
The invention relates to an agricultural bactericide, and in particular relates to a copper hydroxide water dispersible granule and a preparation method thereof. The copper hydroxide water dispersible granule provided by the invention comprises the following ingredients by weight percentage: 30-50% of dispersing agent, 29-39% of copper hydroxide powder, 3-12% of wetting agent, 4-20% of disintegrating agent, 4-18% of swelling agent and 1-20% of chelating agent. The preparation ingredients provided by the invention can effectively prevent and eliminate bacterioses and fungal diseases of crops. Copper hydroxide is taken as the active ingredient of copper preparation to effectively overcome the defect that copper ions are difficult to control by Bordeaux mixture. While being used in field, the substances can effectively balance and stabilize the copper ions on the surface of crops. Thus the diseases of crops are effectively prevented and eliminated and in addition, phytotoxicity of burns to crops and the like can be effectively avoided.
Description
Technical field
The present invention relates to a kind of disinfectant use in agriculture, be specifically related to a kind of Kocide SD water dispersible granules and preparation method thereof.
Background technology
Copper agent is important disinfectant use in agriculture, has the development time early, grows, uses characteristics such as area is big, bactericidal effect good, of many uses service time.Copper agent can be prevented and treated fungal disease, can prevent and treat bacterial disease again, finds also that in recent years the copper agent soil treatment prevention viroses of plant have good effect.Pathogen both there had been protective effect, and had had treatment and eradicant action concurrently.Copper agent has the advantages that toxicity is low, nuisanceless, environment compatibility is good in addition, therefore is the good bactericide of producing pollution-free food, organic fruit.
Early stage copper agent uses the bordeaux mixture effect fine; But but find to be easy to generate poisoning; Especially after labour cost improves; The plantation family all adds medicaments such as insecticide, foliage fertilizer in order to save the time spent when recruitment spray is with copper agent usually, and in order to evade the poisoning risk, peasant household usually abandons copper agent.But copper agent still has the irreplaceable effect of other medicaments, particularly bacterial disease is had unique preventive effect especially.
The copper agent sterilization real acting be copper ion, but the copper ion of blade face cohesion in case surpass the tolerant concentration of crop will cause crop burn, poisoning.
Summary of the invention
Be to solve the use restriction of existing copper preparation, the present invention provides a kind of novel Kocide SD water dispersible granules, and the present invention is a kind of Kocide SD water dispersible granules that plant pathogenic fungi and bacterium are all had control efficiency.
Kocide SD water dispersible granules of the present invention; Form by comprising following components in weight percentage: dispersant 30%-50%, Kocide SD powder 29%-39%, wetting agent 3%-12%; Disintegrant 4%-20%, swelling agent 4%-18%, chelating agent 1%-20%.
Preferably,
Said dispersant is one or more in stearmide, polyacrylic acid, maleic anhydride, isobutene acid amide, sodium lignin sulfonate, diatomite, the polyethylene glycol.
Said wetting agent is one or more in lauryl sodium sulfate, butyl naphthalene sulfonate, sodium alkyl benzene sulfonate, alkylsulfonate, the alkylphosphonic.
Said disintegrant is one or several in sodium carboxymethyl starch, dried starch, mineral salt, white carbon, the silica gel.
Said swelling agent is an aluminium-magnesium silicate.
Said chelating agent is one or more in citric acid, oxalic acid, ethylenediamine tetra-acetic acid (EDTA), the big sodium acetate EDDHA-Na of ethylenediamine two adjacent phenyl, disodium EDTA EDTA-2Na, CDTA, diethylenetriamine pentaacetic acid, the aminotriacetic acid.
The present invention also provides the preparation method of said Kocide SD water dispersible granules, and this method comprises the steps:
1) proportion liquid: in tank diameter, add Kocide SD powder, dispersant, wetting agent, swelling agent, chelating agent successively and stir; 2) wet type ultramicro grinding: coarse crushing in the sand milling pot, micro mist is broken in sand mill, and micro mist 2-4 micron, slurry are squeezed in the head tank by pump and are stored; 3) spray drying granulation: slurry gets into the pressure nozzle of press spray drier top center behind high-pressure pump, and the inlet temperature of this drier is 170 ℃-250 ℃, 65 ℃-120 ℃ of outlet temperatures.
The present invention selects Kocide SD to come effectively to evade the shortcoming that bordeaux mixture is difficult to control copper ion as the active ingredient of copper agent; And our Kocide SD of processing is made water dispersible granules; This formulation availability is high, few in processing and use dust, and environment and health are had no side effect basically.This formulation adopts multiple stabilizing agent, dispersant, chelating agent etc. simultaneously again; Under the coordinative role of multiple composition; The both effectively rate of release of balance copper ion and distributions of crop surface have characteristics such as disintegration is fast, good dispersion, suspension is good, the soup particle is thin again, the copper ion of these materials ability active balances and stable crop surface in the use of farmland; Can efficiently prevent and kill off the disease of crops, can effectively evade again symptom of chemical damage such as burning of crops.Preparation composition of the present invention can efficiently be prevented and kill off bacteriosis and the fungal disease of crops.
