Abstract
The invention relates to carbosulfan emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The carbosulfan emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of carbosulfan, 5%-10% of emulsifying agent, 8%-12% of water-soluble polymer, and the balance of carriers. The preparation method comprises the following steps: mixing liquid carbosulfan and the emulsifying agent uniformly firstly; adding carbosulfan after mixing into a water solution of the water-soluble polymer, and mixing uniformly, thus viscous emulsion is obtained; then adding the carriers into the viscous emulsion, thus a pre-granulating mixture is obtained; and finally granulating and drying. The granules provided by the invention are emulsifiable granules without adding an organic solvent, can be completely emulsified by adding water in use, can achieve good effect at low concentration and have quick effects and duration; and bactericidal effect is superior to other dosage forms with the same active ingredients.
Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide, but but relate in particular to the preparation method of a kind of carbosulfan emulsification granula and carbosulfan emulsification granula.
Background technology
Carbosulfan is a kind of highly effective and safe, insecticidal/acaricidal agent easy to use, and its insecticidal spectrum is wide, and lethality is strong; Instant effect, the lasting period is long, is the inhibitor of cholinesterase; Have tag, stomach toxicity and systemic action, penetration is strong, effect rapidly; Aphid, citrus rust mite etc. all there is very high killing effect, can prevents and treats diversified economy crop pests such as fruit such as citrus and vegetables, corn, cotton, paddy rice, sugarcane.
At present; The formulation of the normal carbosulfan that uses has microemulsion, aqueous emulsion, three kinds of formulations of missible oil; But these three kinds of formulations are all having deficiency aspect quick-acting, lasting effect, the feature of environmental protection, exist drug effect not good, need to use heavy dose of carbosulfan just can reach the purpose of desinsection; Especially the used solvent of missible oil formulation (EC) mainly is aromatic hydrocarbon substances such as toluene and xylol; Not only contaminated environment has also been wasted a large amount of petroleum resources simultaneously, does not meet the requirement and the trend of agricultural sustainable development.
Summary of the invention
Said defective above the objective of the invention is to be directed against, but a kind of quick-acting, lasting effect, carbosulfan emulsification granula that the feature of environmental protection is good are provided.
But another object of the present invention provides a kind of preparation method of carbosulfan emulsification granula.
The objective of the invention is to be achieved through following technical scheme.
But a kind of carbosulfan emulsification granula is characterized in that, comprises the raw material of following weight portion: carbosulfan 20-60%, and emulsifier 5-10%, water-soluble polymer 8-12%, surplus is a carrier.
Said carbosulfan is a liquid.
Said emulsifier is selected from a kind of in nonionic and anion compounded surfactant, nonionic phosphate, the nonionic sulfuric ester.
Said water-soluble polymer is selected from a kind of in polyvinyl alcohol (PVA), sodium carboxymethylcellulose (CMC), the sodium carboxymethyl starch (CMS), is made into the aqueous solution by 1:8-12.
Said carrier is selected from a kind of in dextrin, sugar, urea, ammonium sulfate, glauber salt, carbonic hydroammonium, Sodium Benzoate, the soluble starch.
But a kind of preparation method of carbosulfan emulsification granula; It is characterized in that; Earlier that liquid carbosulfan and emulsifier is even, mixed carbosulfan is added in the aqueous solution of water-soluble polymer, mixes the emulsion that obtains thickness; Carrier is added in the emulsion of thickness again and obtain preparatory granulation mixture, last granulation is also dry.
The invention has the beneficial effects as follows: but 1, the present invention is for a kind of emulsification granula that does not add organic solvent, adds water emulsification fully during use, uses low concentration just can obtain high effect, drug effect is superior to other formulation of identical effective ingredient; 2, have quick-acting and lasting effect, can keep long-term superior effect; 3, have powerful interior suction, penetration; 4, said emulsifier has high HLB value; Be not easy to be saltoutd out; Said water-soluble polymer can keep colloidal stability in the preparation that solidifies; But can prepare the emulsification granula that contains the former medicine of a lot of liquid, said carrier is water-soluble, with the adsorbable a lot of liquid of the prilling process of rotation extrusion comminutor extrusion molding; 5, the particle body is convenient to packing and transportation.
