Embodiment 1

[0015] Example 1: 1.11% penoxsulam·pretilachlor·pyrazosulfuron-methyl fertilizer granules

[0016] Penoxsulam 0.01%, Pretilachlor 1%, Pyrazosulfuron-methyl 0.1%, Urea 30%, Diammonium Phosphate 5%, Potassium Chloride 10%, Borax 1%, Zinc Sulfate 1%, Polycarboxylate 2%, alkyl naphthalene formaldehyde condensate sulfonate 3%, white carbon black 3%, xanthan gum 0.5%, sodium aluminum silicate 0.5%, preservative 0.5%, propylene glycol 5%, water to 100%;

[0017] The process is as follows: According to the above ratio, mix the ingredients evenly in a closed mixing tank, add them to the granulation equipment for coating granulation, and sieve the particle size below 5UM after drying to obtain five Flusulam · Pretilachlor · Pyrazosulfuron-methyl fertilizer granules;

Embodiment 2

[0018] Example 2: 8.1% penoxsulam·pretilachlor·pyrazosulfuron-methyl fertilizer suspension concentrate

[0019] Penoxsulam 0.1%, pretilachlor 6%, pyrazosulfuron-methyl 2%, urea 20%, diammonium phosphate 15%, potassium chloride 10%, zinc sulfate 2%, white carbon black 2%, formazan 5% formaldehyde condensate of sodium naphthalene sulfonate, 1% polycarboxylate, 3% sodium lignosulfonate, and light calcium carbonate make up to 100%;

[0020] The process is to mix polycarboxylate, alkylnaphthalene formaldehyde condensate sulfonate, white carbon black, xanthan gum, sodium aluminum silicate, preservative, propylene glycol, and water according to the above formula ratio, and then mix evenly by high-speed shearing , add penoxsulam, pretilachlor, pyrazosulfuron-methyl, urea, diammonium phosphate, potassium chloride, borax, zinc sulfate, continue to shear and mix evenly, and then grind in a horizontal sand mill to make the preparation Penoxsulam, pretilachlor, and pyrazosulfuron-methyl f...

Embodiment 3

[0021] Example 3: 15% penoxsulam·pretilachlor·pyrazosulfuron-methyl fertilizer wettable powder

[0022] Penoxsulam 1.5%, pretilachlor 12%, pyrazosulfuron-methyl 1.5%, urea 30%, diammonium phosphate 5%, potassium chloride 15%, zinc sulfate 2%, tripolyphosphoric acid 3%, diammonium phosphate Sodium methyl bis-naphthalene sulfonate 8%, talcum powder 7%, kaolin make up to 100%;

[0023] Weigh each component according to the above proportions, coarsely pulverize the solid component and send it to the mixer together with other components to mix evenly, and then air-jet pulverize to obtain penoxsulam·pretilachlor·pyramid rimsulfuron-methyl fertilizer wettable powder;

Abstract

The invention provides a pesticide-fertilizer composition. The pesticide-fertilizer composition comprises a weeding component, a fertilizer component and auxiliary components for pesticide formulation processing, wherein the weeding component contains penoxsulam, pretilachlor and pyrazosulfuron-ethyl. The pesticide-fertilizer composition is prepared from the following ingredients in percentage by weight: 0.01% to 20% of penoxsulam, 1% to 60% of pretilachlor, 0.1% to 30% of pyrazosulfuron-ethyl, 10% to 60% of fertilizer component and the balance of auxiliary components for pesticide formulation processing. According to the pesticide-fertilizer composition prepared from the three kinds of weeding ingredients and the fertilizer component, not only can weeds be prevented, but also nutrients essential for crops can be supplemented; and after the weeding ingredients and the fertilizer component are compounded, compared with a fertilizer and a herbicide in separate use, the aspects such as weeding effect and yield increase are remarkably improved, the fertilizer and the herbicide can be saved, the quantity of steps of pesticide application and fertilizer application is reduced, the labor cost is reduced, and the safety to the crops is high.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a mixture of pesticides and fertilizers, in particular to a medicinal fertilizer composition. Background technique [0002] There is a direct or indirect relationship between pesticides, fertilizers, soil and crops. With the development of agricultural production and the continuous improvement of the level of science and technology, the mixed use of pesticides and fertilizers, which makes the two operation steps in the field into one, has become an important development direction in the agricultural field. The research on medicinal fertilizers was first seen in the 1964 "Research Report on the Agricultural Experimental Field in Northeast Japan". The base fertilizer is applied in order to achieve the purpose of saving labor and continuing the weeding effect. The research on medicinal fertilizers in my country began in the 1980s, and there are many studies at present, but the research on s...
