Problems solved by technology

[0008] The purpose of the present invention is to solve the problems in the prior art that when a single pesticide is used alone, it is easy to produce resistance to weeds and the actual control effect is poor, and to provide a high-efficiency, broad-spectrum, economical, safe, and beneficial to the comprehensive management of weeds. herbicidal composition

Embodiment 1

[0016] Example 1: Indoor Toxicity Determination of Toxazone, Chlorpyrazosulfuron-methyl, Atrazine and Their Compounds to Setairaviridis (L.) Beauv and Cyperus rotundus L.

[0017] According to the Colby method to evaluate the combination of herbicides (NY / T1155.7-2006), the formula is as follows:

[0018] E 0 = A × B × C × . . . N 100 ( n - 1 ) .

[0019] In the formula: A is the fresh weight inhibition rate of the target weeds when pyrenzazone is used alone at a certain dose;

[0020] B is the fresh weight inhibition rate of target weeds when chlorpyrazosulfuron-methyl is used alone at a certain dose;

[...

Embodiment 2

[0034] Example 2: (Metrametrazone · Clorazosulfuron · Atrazine water dispersible granules).

[0035]

[0036] Put the above materials together into the conical mixer and mix them evenly, and then crush them through the jet mill, and then mix the crushed materials through the conical mixer. Knead into a plastic material, and finally put this material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain the corresponding weight percentage of pyrazazone-chlorpyrazosulfuron-methyl Atrazine water dispersible granules.

Embodiment 3

[0037] Example 3: (Metramezone · Clorazosulfuron · Atrazine wettable powder).

[0038]

[0039] Put the above materials together into the conical mixer and mix them evenly, then pulverize them through the jet mill, and then mix the pulverized materials through the conical mixer. The fineness of the mixed materials is 98% and pass through a 600-mesh standard sieve to obtain the corresponding weight Percentage of fenpyrazone · chlorpyrazosulfuron · atrazine wettable powder.

Abstract

The invention discloses a weed control composition containing atrazine. The weed control composition comprises the following ingredients by weight percent: 0.1-50% of topramezone, 1-40% of halosulfuron-methyl,1-60% of atrazine and the balance of pesticide adjuvants, wherein the topramezone, the halosulfuron-methyl and the atrazine are active ingredients. The weed control composition is used for controlling annual weeds in the corn fields, has obviously effects better than the corresponding single agent, expands the weed control spectrum, also reduces the dosage, delays the drug resistance of weeds and reduces environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic response herbicidal composition with fenpyrazone, chlorpyrazosulfuron-methyl and atrazine as active ingredients, especially for Setaira viridis (L. ) Beauv) and Cyperus rotundus L. have obvious synergistic responses, and are mainly suitable for controlling cornfields, especially Setaira viridis (L.) Beauv) and Cyperus rotundus L. as dominant weeds Annual weed in cornfields. Background technique [0002] Topramezone, a pyrazolone post-emergence stem and leaf treatment agent, can be absorbed by roots, young stems and leaves, and inhibits the double oxidation of 4-hydroxyphenylpyruvate in plastoquinone biosynthesis The enzyme (4HPPD), which indirectly affects the synthesis of carotenoids, interferes with the synthesis and function of chloroplasts, and eventually causes severe albinism (due to the degradation of chlorophyll), is highly selective for maiz...
