Embodiment 1

[0028] Example 1: (40% difenoconazole · ecumazole aqueous suspension concentrate)

[0029] The components and weight content of the water suspension containing difenoconazole in this example are as follows: difenoconazole, 10%; Agent polycarboxylate, 8%; thickener selection xanthan gum and magnesium aluminum silicate, the dosage is 0.1% and 2% respectively; antifreeze agent ethylene glycol, 5%; defoamer silicone compound, 0.5% ; water, balance.

[0030] The production method of the difenoconazole-containing water suspension in this example: the active ingredients difenoconazole and euconazole, surfactants and other functional additives are placed in the batching kettle in sequence, and water is added to mix evenly , high-speed shearing, wet sanding, and finally homogeneous filtration to obtain the product. The main equipment is batching kettle, colloid mill and sand mill.

Embodiment 2

[0031] Example 2: (50% difenoconazole·ecumazole wettable powder)

[0032] The difference between this example and Example 1 is that the components and weight content of the water suspension containing difenoconazole in this example are as follows: difenoconazole, 15%; Agent ethylene oxide-propylene oxide block copolymer, 3%; dispersant polycarboxylate, 8%; thickener selection of xanthan gum and magnesium aluminum silicate, the dosage is 0.1% and 2% respectively; antifreeze Agent glycol, 5%; defoamer silicone compounds, 0.5%; water, the balance.

Embodiment 3

[0033] Example 3: (65% difenoconazole·ecumazole water dispersible granule)

[0034] The difference between this example and Example 1 is that the components and weight content of the water suspension containing difenoconazole in this example are as follows: difenoconazole, 20%; Agent Nongru OP-10, 2%; Dispersant lignosulfonate, 9%; Thickeners choose xanthan gum and magnesium aluminum silicate, the dosage is 0.1% and 2% respectively; Antifreeze agent ethylene glycol, 5% %; defoaming agent silicone compounds, 0.5%; water, the balance.

Abstract

The invention belongs to the field of farm chemical fungicide and particularly relates to a water suspending agent containing difenoconazole. The water suspending agent comprises difenoconazole, bismerthiazol, a surfactant and water, wherein the weight content of difenoconazole is 1-20%, and the weight ratio of difenoconazole to bismerthiazol is 5:1-1:5. The water suspending agent further comprises other functional promoters. The composition is mainly used for preventing and treating watermelon gummy stem blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, blacking disease, citrus scabs, rice bacterial leaf blight, cucumber brown patches and the like. The composition has the advantages of being obvious in synergism, broad in bacteria killing, long in effect persisting time, safe for crops and the like.

Description

technical field [0001] The invention belongs to the field of agricultural fungicides, in particular to an aqueous suspension containing difenoconazole, a production method and application thereof. Background technique [0002] Difenoconazole is a broad-spectrum and high-efficiency fungicide, which mainly inhibits the biosynthesis of ergosterol in pathogen cells, thereby destroying the structure and function of cell membranes. It is mainly used in fruit trees, vegetables, wheat, potatoes, beans, melons and other crops , It has very good protective and therapeutic effects on various fungal diseases such as vegetables and melons and fruits. However, it has little mobility in soil and slowly degrades. It can control pear scab, apple spot defoliation, tomato drought blight, watermelon blight, pepper anthracnose, strawberry powdery mildew, grape anthracnose, black scab, citrus scab, etc. the [0003] Ectilazole (Yeqingshuang) is a systemic fungicide independently developed ...
