Embodiment 1

[0028] Embodiment 1: 60% carbamide-propanil suspension concentrate

[0029] 40% of grass grass, 20% of propanil, 4%-5% of grass tincture, 0.002% of bratin lactone solution, 4% of sodium p-styrene sulfonate, 0.1% of ammonium persulfate, 5% of urea, silicic acid Magnesium aluminum 0.8%, diluent to make up to 100%.

[0030] The preparation method is as follows: the above raw materials are weighed according to the parts by weight, mixed, dispersed for 30 minutes by high-speed shearing machine, heated to 50°C, reacted for 6 hours, and then ball milled by a ball mill for 1 hour to obtain the product.

Embodiment 2

[0031] Embodiment 2: 60% carbamide-propanil suspension concentrate

[0032] 20% grass grass, 40% propanil, 4%-5% grass tincture, 0.0025% bratin lactone solution, 4% nonylphenol polyoxyethylene ether, 0.1% ammonium persulfate, 5% ethanol, silicon Magnesium aluminum acid 1%, diluent make up to 100%. The preparation method is the same as in Example 1.

Embodiment 3

[0033] Embodiment 3: 50% carbamide-propanil suspension concentrate

[0034] 30% grass grass, 20% propannil, 4%-5% grass tincture, 0.003% bratinolactone solution, 6% sodium octadecenoate, 0.1% ammonium persulfate, 5% urea, magnesium silicate Aluminum 0.8%, diluent to make up to 100%. The preparation method is the same as in Example 1.

Abstract

The invention discloses a novel suspending agent containing benthiocarb and propanil, which is characterized in that benthiocarb and propanil are used as main effective components, a biological regulator, namely brassinolide, is added and is prepared into a brassinolide solution by using sodium octadecenoate before addition, brassinolide is connected with propanil and benthiocarb through emulsion polymerization reaction to prepare the novel suspending agent containing benthiocarb and propanil, and the obtained suspending agent is simple to prepare, excellent in storage stability, capable of efficiently preventing and treating grassy weeds and broad leaf weeds such as resistant barnyard grass and resistant moleplant seeds, capable of effectively improving the weeding effect, capable of reducing the weeding frequency, capable of saving the production cost, can promote the growth of paddy rice, and lays a foundation for increasing the yield of rice and increasing the income of farmers.

Description

technical field [0001] The invention relates to a novel suspending agent containing milticarb and propanil, belonging to the technical field of pesticides. Background technique [0002] Rice is not only the most important food crop in my country, but also one of the main food crops in the world. Rice production is also spread on all continents except Antarctica. There have always been a large number of weeds growing in the paddy fields of all rice-growing areas in my country. The grain loss due to weeds in our country is as high as 20 billion kilograms every year, and the proportion of herbicides used in paddy fields is almost 100%. [0003] Mesocarb is insoluble in water but easily soluble in organic solvents. It is a selective systemic herbicide, which is mainly absorbed through the roots and young shoots of weeds, and has a strong inhibitory effect on the growth point. Propannil is a highly selective contact herbicide of amides, mainly used in seedling fields or direct-s...
