Embodiment 1

[0057] Example 1: Preparation of 24% dipacenil·pretilachlor·bensulfuron-methyl suspension concentrate (active ingredient 1:1:10)

[0058] The raw materials are as follows:

[0059]

[0060] Production process: first put the weighed pyracloxenil, pretilachlor, bensulfuron-methyl, wetting agent BC-10, dispersant FD, antifreeze ethylene glycol and water into the reaction kettle, cut 10-40 Minutes, grind the sheared material through a sand mill for 2-4 times, and add defoamer while grinding. After the grinding is finished, add the thickener xanthan gum to the ground material, and then cut it for 10-30 minutes, so that the particle size is all below 5 μm, and the herbicidal preparation aqueous suspension of the present invention is prepared.

Embodiment 2

[0061] Example 2: Preparation of 48% dipacenil·butachlor·pyrazosulfuron-methyl suspension concentrate (active ingredient 1:10:1)

[0062] The raw materials are as follows:

[0063]

[0064] Production process: first put the weighed pyracloxachlor, butachlor, pyrazosulfuron-methyl, wetting agent BC-10, dispersant FD, antifreeze ethylene glycol and water into the reaction kettle, cut 10-40 Minutes, grind the sheared material through a sand mill for 2-4 times, and add defoamer while grinding. After the grinding is finished, add the thickener xanthan gum to the ground material, and then cut it for 10-30 minutes, so that the particle size is all below 5 μm, and the herbicidal preparation aqueous suspension of the present invention is prepared.

Embodiment 3

[0065] Example 3: Preparation of 30% dipacenil·tetramide·promasulfuron-methyl suspension concentrate (active ingredient 8:1:1)

[0066] The raw materials are as follows:

[0067]

[0068] Production process: first put the weighed bisfenpyr, tetramen, rimsulfuron-methyl, wetting agent BC-10, dispersant FD, antifreeze ethylene glycol and water into the reaction kettle, cut After 10-40 minutes, grind the sheared material through a sand mill for 2-4 times, and add defoamer while grinding. After the grinding is finished, add the thickener xanthan gum to the ground material, and then cut it for 10-30 minutes, so that the particle size is all below 5 μm, and the herbicidal preparation aqueous suspension of the present invention is prepared.

Abstract

The invention relates to a weeding composition. The weeding composition contains pyraclonil, an amide herbicide second active ingredient and a sulfonylurea herbicide third active ingredient, wherein the amide herbicide second active ingredient is herbicide selected from pretilachlor, machette, or fentrazamide; the sulfonylurea herbicide third active ingredient is herbicide selected from bensulfuron methyl, pyrazosulfuron-ethyl or propyrisulfuron; the weight ratio of the pyraclonil to the amide herbicide second active ingredient to the sulfonylurea herbicide third active ingredient is (1 to 10):( 1 to 10):( 1 to 10), and is preferably (1 to 8): (1 to 8): (1 to 8).

Description

[0001] 【Technical field】 [0002] The invention belongs to the field of pesticides. More specifically, the present invention relates to a herbicidal composition containing dipacenil, the second active ingredient of an amide herbicide and the third active ingredient of a sulfonylurea herbicide, and also relates to the use of the herbicidal composition in controlling rice fields. Application on weeds. [0003] 【technical background】 [0004] Rice, an annual grass plant, monocot, likes high temperature, humidity, and short sunshine, and is also the most important and longest food in the genus Oryza. Rice is the largest food crop in my country. There are many types of weeds in paddy fields, and the types of weeds are different in different regions. There are more than 200 species of weeds in rice areas across the country, of which there are about 40 common and serious weeds. Among the main weeds, barnyardgrass has the largest occurrence and damage area, followed by heteromorphous ...
