Embodiment 1

[0016] A herbicide for vegetable fields provided in this example is composed of the following weight percentages: 10% of the first active active ingredient, 60% of the second active active ingredient, 10% of adjuvants, and 20% of fillers.

[0017] The first active ingredient in Example 1 is a mixture of tembotrione and flucarbasulfuron; the mass ratio of tembotrione and flucarbasulfuron is 1:3. The second active active ingredient is dimethyltetrachloride. The auxiliary agent is a combination of emulsifier and wetting agent; the mass ratio of emulsifier and wetting agent is 2:5. The filler is a combination of high clay and organic bentonite. The emulsifier is a combination of alkylphenol polyoxyethylene ether formaldehyde condensate 700# and styrene ethylphenol polyoxyethylene ether 600#. The dispersant is a combination of polycarboxylate and alkyl naphthalene sulfonate. The wetting agent is a combination of alkyl sulfates and alkyl sulfonates.

Embodiment 2

[0019] A herbicide for vegetable fields provided in this example is composed of the following weight percentages: 5% of the first active active ingredient, 70% of the second active active ingredient, 5% of adjuvants, and 20% of fillers.

[0020] The first active active ingredient in Example 2 is a mixture of tembotrione and flucarbasulfuron-methyl; the mass ratio of tembotrione and flucarbasulfuron-methyl is 3:1. The second active ingredient is 2,4-D butyl ester. The auxiliary agent is a combination of emulsifier, dispersant and wetting agent; the mass ratio of emulsifier and wetting agent is 5:2. The filler is a combination of clay and diatomaceous earth. The emulsifier is a combination of phenylethylphenol polyoxyethylene ether 600# and calcium alkylbenzenesulfonate 500#. The dispersant is a combination of alkylnaphthalene sulfonate and alkylphenol polyoxyethylene ether. The wetting agent is a combination of alkylsulfonates and naphthalenesulfonates.

Embodiment 3

[0022] A herbicide for vegetable fields provided in this example is composed of the following weight percentages: 10% of the first active active ingredient, 20% of the second active active ingredient, 10% of adjuvants, and 60% of fillers.

[0023] The first active ingredient in Example 3 is a mixture of tembotrione and flucarbasulfuron; the mass ratio of burasulfone and flucarbasulfuron is 2:1. The second active active ingredient is a combination of dimethyltetrachloride and 2,4-D butyl ester. The auxiliary agent is a combination of emulsifier, dispersant and wetting agent; the mass ratio of emulsifier and wetting agent is 3:2. The filler is a combination of high clay, organic bentonite, pottery clay and diatomite. The emulsifier is a combination of alkylphenol polyoxyethylene ether formaldehyde condensate 700#, styrene ethylphenol polyoxyethylene ether 600# and alkylbenzene sulfonate calcium 500#. The dispersant is a combination of polycarboxylate, alkylnaphthalene sulfonat...

Abstract

The invention discloses a weed killer for a vegetable garden. The weed killer comprises the following components in percentage by weight: 10-15% of a first active effective constituent, 10-70% of a second active effective constituent, 5-10% of an additive and 5-80% of a filling material, wherein the sum of the weight of the first active effective constituent and the weight of the second active effective constituent is 1-80% of the total weight of the weed killer, the first active effective constituent is a mixture of tembotrions and flucarbazone according to the mass ratio of (1:3)-(3:1), the second active effective constituent is MCPA or 2,4-D butyl ester, the additive is one or composition of two or more than two of an emulsifying agent, a dispersing agent and a wetting agent, the mass ratio of the emulsifying agent to the wetting agent is (2:5)-(5:2), and the filling material is one or composition of two or more than two of high clay, organic bentonite, pottery clay and diatomite.

Description

technical field [0001] The invention relates to a herbicide for vegetable fields. Background technique [0002] Weeds will compete with crops for glory, fertilizer and water, so weeds in farmland cause great losses to crop production every year. Therefore, it is necessary to configure a highly efficient herbicide. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a pollution-free herbicide for vegetable fields. [0004] In order to solve the above technical problems, the present invention provides a herbicide for vegetable fields, each component in the herbicide includes by weight percentage: 10-15% of the first active active ingredient, 10-70% of the second active active ingredient %, 5-10% of adjuvants, 5-80% of fillers; the sum of the mass of the first active active ingredient and the second active active ingredient is 1-80% of the total mass of the herbicide; ...
