Technical field

The invention belongs to technical field of pesticide, specially a kind of fosthiazate water-soluble granula and its preparation side containing stabilizer Method.

Background technique

Vegetables root nematode aggravates year by year in global harm, in the current vegetables in greenhouse booth in China, ginger, and citrus, Banana has become a problem very outstanding.Fosthiazate is the novel organophosphorus class of Japanese Ishihara Sangyo Kaisha, Ltd.'s exploitation Nematicide, trade name happy lot is more, is 10% fosthiazate granule, obtains cucumber in first Chinese in 2002, tomato steps on Note has great reputation in the large-scale popularization application of the ground such as Shandong Shouguang, in terms of practical effect, has effect stability, Lasting period is long, to human and environment safety, meets Vegetables Exportation requirement.

But current fosthiazate granula easily decomposes there are stability difference and is only capable of the soil before planting and spreads fertilizer over the fields prevention and treatment root knot line Worm, the drawbacks of can not using in process of crop growth, and local concentration is higher in the soil, be easy to cause medicine to crop root Evil；The popularization of water-fertilizer integral is maked rapid progress, but fosthiazate granule can not match, and limits its further development, Inventor thus, comprehensive all kinds of factors propose a kind of fosthiazate water-soluble granula and preparation method thereof containing stabilizer.

Summary of the invention

It is an object of the invention to: in order to solve the technical issues of background technique is related to, provide a kind of thiophene containing stabilizer Azoles phosphine water-soluble granula and preparation method thereof.

The technical solution adopted by the invention is as follows:

A kind of fosthiazate water-soluble granula containing stabilizer, including quality accounting are 5%~15% active constituent fosthiazate, 2%~4% Stabilizer, 2% emulsifier and surplus be the carrier that is used as of graininess cornstarch；

The stabilizer is epoxychloropropane, and the emulsifier is the sulfonated bodies of laruyl alcohol.

Wherein, the HLB value of the sulfonated bodies of laruyl alcohol is 15 in the emulsifier.

Wherein, the carrier is graininess cornstarch, and grain fineness is 20~40 mesh, oil factor 15-20%.

A kind of preparation method of the fosthiazate water-soluble granula containing stabilizer, will be by fosthiazate, stabilizer, and emulsifier is mixed It is even, medicine liquid spray is stirred evenly in the graininess cornstarch for being in stirring under pressure.

A kind of application method of the fosthiazate water-soluble granula containing stabilizer, including conventional granula is spread fertilizer over the fields, ditch spread, and directly Water is dissolved in apply with water-fertilizer integral.

In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:

1, the fosthiazate preparation can completely dissolve in water in the present invention, form the medical fluid of clear, be not precipitated within 24 hours, Spray head will not be blocked when use.

2, the present invention can prevent and treat crop root-knot nematode by water-fertilizer integral facility, widen the application window of fosthiazate granula The mouth phase.

3, the water-soluble characteristic of the present invention improves fosthiazate and to the distribution consistency degree around root system, is improving to root system peace Quan Xing.

4, the stabilizer that contains of the present invention can make active constituent under 54 degree of storage conditions of high temperature resolution ratio less than 3%, Greatly improve its commodity performance.

Specific embodiment

In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to embodiments, to the present invention It is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, is not used to limit The fixed present invention.
