Abstract
The invention relates to profenofos emulsifiable granules and a preparation method thereof, and relates to an agricultural bactericide. The profenofos emulsifiable granules comprise the following raw materials in percentage by weight: 20%-60% of profenofos, 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 profenofos and the emulsifying agent uniformly firstly; adding profenofos 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 can achieve good effect at low concentration, have quick acting and duration, and can maintain the effect for a long time; and the granules have strong internal absorption property and permeability, and can kill leaf rollers in leaves.
Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide, relate in particular to the preparation method of a kind of profenofos emulsifiable granules and profenofos emulsifiable granules.
Background technology
Profenofos is a kind of novel organic phosphates broad spectrum pesticide, has the features such as efficient, wide spectrum, interior suction, low-residual, is acetylcholinesteraseinhibitors inhibitors, has and tags and stomach poison function, can prevent and treat harmful insect and the mite class of cotton, vegetable field.Because the cotton-plant pest-insects that Profenofos produces resistance to other organic phosphors, pyrethroid are still effective, successful in vegetable insect disease control, therefore usage amount day by day increases, although a small amount of Profenofos is residual, can cause immediately human body, directly poison, but the molecular structure of Profenofos is more stable, be difficult in vivo be decomposed, drain by metabolism, long-term edible contaminated vegetables can cause the diseases such as cancer, apogeny, endocrine disturbance, serious base be to can endanger nerve center, so that spasm and dead.And Profenofos is mostly missible oil (EC) product at present, and solvent used is mainly the aromatic hydrocarbon substances such as toluene and dimethylbenzene, and contaminated environment, has wasted again a large amount of petroleum resources, does not meet requirement and the trend of agricultural sustainable development.
Summary of the invention
The object of the invention is, for described defect above, provides a kind of consumption little, quick-acting, lasting effect, the profenofos emulsifiable granules that the feature of environmental protection is good.
Another object of the present invention is to provide a kind of preparation method of profenofos emulsifiable granules.
The object of the invention is to be achieved by the following technical programs.
, it is characterized in that, comprise the raw material of following weight portion: Profenofos 20-60%, emulsifier 5-10%, water-soluble polymer 8-12%, surplus is carrier.
Described Profenofos is liquid.
Described emulsifier is selected from a kind of in nonionic and anion compounded surfactant, nonionic phosphate, nonionic sulfuric ester.
Described water-soluble polymer is selected from a kind of in polyvinyl alcohol (PVA), sodium carboxymethylcellulose (CMC), sodium carboxymethyl starch (CMS), by 1:8-12, is made into the aqueous solution.
Described carrier is selected from a kind of in dextrin, sugar, urea, ammonium sulfate, glauber salt, carbonic hydroammonium, Sodium Benzoate, soluble starch.
A kind of preparation method of profenofos emulsifiable granules; it is characterized in that; first liquid Profenofos and emulsifier are mixed; mixed Profenofos is added in the aqueous solution of water-soluble polymer; mix the emulsion that obtains thickness; carrier is added in the emulsion of thickness again and obtain pre-granulation mixture, last granulation is also dry.
The invention has the beneficial effects as follows: 1, the present invention overcomes the shortcoming that existing Profenofos missible oil product is used in a large number aromatic hydrocarbon solvent, the pollution on the environments such as toluene and dimethylbenzene relatively seriously and is difficult for degraded, provide a kind of do not add organic solvent can emulsification granula, during use, add water emulsification completely, drug effect is better than the Profenofos missible oil formulation of identical active ingredient completely.2, use low concentration just can obtain high effect, there is quick-acting and lasting effect, can keep for a long time effect.3, there is powerful interior suction, penetration, can kill the leaf roll snout moth's larva in leaf.4, described emulsifier has high HLB value; be not easy to be saltoutd out; described water-soluble polymer can keep colloidal stability in curing preparation; what can preparation contain the former medicine of a lot of liquid can emulsification granula; described carrier is water-soluble, with the adsorbable a lot of liquid of prilling process of rotary squeezing comminutor extrusion molding.5, particle body is convenient to packing and transportation.
