Embodiment 1

[0018] Biological Assay Example 1: Indoor Toxicity Tests of Mefenpyramid, Cyhalofop-ethyl, Clorazosulfuron-methyl and their compound Stephania chinensis, and Heterocyperus sinensis.

[0019] According to the Colby method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula is as follows:

[0020] E 0 = A × B × C × . . . N 100 ( n - 1 )

[0021] In the formula:

[0022] A is the fresh weight inhibition rate of target weeds when oxafenamide is used alone at a certain dose;

[0023] B is the fresh weight inhibition rate of target weeds when cyhalofop-ethyl is used alone at a certain dose;

[0024]...

Embodiment 1

[0035] Formulation example 1: 20% oxafluzamide·cyhalofop-methyl·chlorpyrazosulfuron-methyl water-dispersible granules.

[0036]

[0037] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 96% and pass through a 800-mesh standard sieve, and then put into the kneader Knead into a plastic material, and finally put the material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain 20% fenpyramid, cyhalofop, and clopyrazine Sulfuron-methyl water-dispersible granules.

Embodiment 2

[0038] Formulation example 2: 35% fenpyramid·cyhalofop-methyl·clopyrazosulfuron-methyl wettable powder).

[0039]

[0040] Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, and then mix the pulverized materials through a conical mixer. The fineness of the mixed materials is 98% and passes through a 600-mesh standard sieve to obtain 35% Fenoxam, cyhalofop-methyl, and chlorpyrazosulfuron wettable powder.

Abstract

The invention relates to an herbicide composition containing metamifop, cyhalofop-butyl and halosulfuron-methyl. The herbicide composition contains active ingredients of the metamifop, the cyhalofop-butyl and the halosulfuron-methyl, wherein the metamifop accounts for 1-20wt% of the composition, the cyhalofop-butyl accounts for 1-30wt% of the composition and the halosulfuron-methyl accounts for 1-20wt% of the composition. The herbicide composition disclosed by the invention has a synergetic effect; in the control and removal of annual weeds in a paddy field, the effect of the herbicide composition is significantly better than that of various single agent in independent use; the herbicide composition can be used for widening a weeding spectrum, and the herbicide composition can be also used for reducing the use quantity of pesticides, reducing weed resistance risks, relieving environment pollution and delaying the generation of weed resistance.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive herbicidal composition with fenpyramid, cyhalofop-ethyl, and chlorpyrazosulfuron-methyl as active ingredients, and is mainly suitable for controlling annual weeds in paddy fields. Background technique [0002] Metamifop can resist acetyl-CoA carboxylase, stop the synthesis of fatty acid, the growth and division of cells cannot be carried out normally, the membrane system and other lipid-containing structures are destroyed, and finally lead to plant death. Mefenpyramid is often used to control annual grass weeds such as daughters, barnyardgrass, and crabgrass, but it is ineffective against sedges and broad-leaved weeds. [0003] Cyhalofop-buty is the only one among the aryloxyphenoxypropionic acid herbicides that is highly safe to rice. Like other varieties in this category, it is also a systemic conductive herbicide. Absorbed by the leaves...
