Problems solved by technology

However, it has low activity against barnyardgrass in paddy fields, and it cannot completely control grass, broadleaf and sedge weeds in paddy fields.
[0005] At present, the use of a single herbicide in paddy fields cannot fully and effectively control the occurrence of weeds in paddy fields. If the amount is too large, it is easy to cause residual toxicity to current crops or subsequent crops.
[0006] Bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl are different in chemical class and mechanism of action, and have great differences in the control of weeds in paddy fields. According to literature search, no bicyclic sulcotrione, pretilachlor Related reports on tertiary compounding of amine and pyrazosulfuron-methyl

Embodiment 1

[0063] Example 1, preparation of granules containing bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl

[0064] (1) Formula:

[0065] The granules containing bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl are composed of the following raw materials in mass percentage: 1.8% of bicyclic sulcotrione, 8.0% of pretilachlor, 0.2% of pyrazosulfuron-methyl, NNO (sodium methylene dinaphthalene sulfonate) 10%, K12 (sodium lauryl sulfate) 3.0%, anhydrous sodium sulfate 25%, ammonium sulfate 25%, kaolin to 100%, CE-810K (fatty acid Methyl ester, its consumption is based on 10 times of pyrazosulfuron-methyl quality) and acetone (its consumption is based on 20 times of pyrazosulfuron-methyl quality).

[0066] (2) Preparation method:

[0067] According to the ratio of the above raw materials, use CE-810K and acetone to dissolve bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl into mother liquor; then put NNO, K12, anhydrous sodium sulfate, ammonium sulf...

Embodiment 2

[0068] Example 2, preparation of granules containing bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl

[0069] (1) Formula:

[0070] The granules containing bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl are composed of the following raw materials in mass percentage: 1.0% of bicyclic sulcotrione, 9.0% of pretilachlor, 0.1% of pyrazosulfuron-methyl, Morwet D-425 (alkyl naphthalene sulfonate formaldehyde condensation polymer) 10%, K12 (sodium lauryl sulfate) 3.0%, anhydrous sodium sulfate 25%, ammonium sulfate 25%, white carbon black 2.0%, bentonite supplement Align to 100%.

[0071] (2) Preparation method:

[0072] According to the above-mentioned raw material ratio, first use white carbon black to absorb pretilachlor and mix it into powder; Put the bentonite into the mixer and mix it evenly, pulverize it into a powder through the ultra-fine jet mill, and then add water and mix it to form a mother powder; the mother powder is granulated and dried by...

Abstract

The invention discloses a compound herbicidal composition and a granule thereof. The herbicidal composition is composed of: benzobicylon, pretilachlor and pyrazosulfuron-ethyl, wherein the mass ratioof the three components is (0.1-50):(5-70):(0.1-10). The granule is prepared with the herbicidal composition as active components and includes, by mass, 0.1-50% of the benzobicylon, 5-70% of the pretilachlor, 0.1-10% of the pyrazosulfuron-ethyl, 5-10% of a dispersant, 0-10% of a wetting agent, 0-10% of a disintegrant, 0-3% of a binder, 0-5% of an adsorbent, and filler added to 100%. The compound granule of the benzobicylon, pretilachlor and pyrazosulfuron-ethyl can be applied in one time, is extended in herbicidal spectrum and increased in application uniformity, is improved in effect and lasting time, is reduced in use amount and application cost, and is also reduced in environment pollution during application.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to a compound herbicidal composition containing bicyclic sulcotrione, pretilachlor and pyrazosulfuron-methyl and its granules. Background technique [0002] Benzobicyclone, also known as benzobicyclone. Chemical name: 3-(2-Chloro-4-methylsulfonylbenzoyl)-2-phenylthiobicyclo[3.2.1]oct-2-en-4-one. Bicyclic sulcotrione is a bicyclic octane chemical herbicide developed by Japan SDS Biotechnology Company, which is used to control annual and perennial weeds in paddy fields. Bicyclic sulcotrione is a p-hydroxyphenylpyruvate dioxygenase inhibitor (HPPD), which affects the synthesis of plastoquinone by inhibiting HPPD, and then acts on phytoene dehydrogenase (PDS) by plastoquinone , which ultimately affects the biosynthesis of carotenoids and causes leaf bleaching. Bicyclic sulcotrione is a broad-spectrum selective herbicide used to control weeds in direct-seeded rice fields a...
