Problems solved by technology

[0007] 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 in cornfields and the actual control effect is poor, and to provide a high-efficiency, broad-spectrum, economical, safe, beneficial to cornfield weeds. Pesticide composition for integrated weed management

Embodiment 1

[0015] Example 1: Metramezone, mesotrione, metolachlor-sperm, atrazine and their compound pairs Setaria viridis, Echinochloa crusgalli, Digitaria sanguinalis, Toxicity determination of Amaranthus retroflexus, Cirsium setosum and Chenopodium album.

[0016] According to the Colby method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula is as follows:

[0017] E 0 = A × B × C × · · · N 100 ( n - 1 )

[0018] In the formula:

[0019] a is the fresh weight inhibition rate of target weeds when fenpyrazone is used alone at a certain dose;

[0020] b is the fresh weight inhibition rate of target we...

Embodiment 2

[0051] Example 2: 75% metrafenone·mesotrione·sperm metolachlor·atrazine water dispersible granules.

[0052]

[0053] 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 the material into an extrusion granulator to extrude and granulate. After granulation, it is dried and sieved to obtain 75% of mesotrione, mesotrione, and refined isopropyl Alachlor · Atrazine water dispersible granules.

Embodiment 3

[0054] Example 3: 60% memetrazone · mesotrione · pure metolachlor · atrazine wettable powder.

[0055]

[0056]

[0057] 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 60% Metrafen, mesotrione, metolachlor, atrazine wettable powder.

Abstract

The invention discloses a pesticide composition containing topramezone. The effective constituents of the pesticide composition comprise topramezone, mesotrione, s-metolachlor and atrazine. The pesticide composition has remarkable synergistic interaction and is obviously superior to single application of a single dose in preventing and eliminating annual weed effect in a corn field; the dosage of the effective constituents of the pesticide composition is remarkably reduced compared with that of the single dose; in addition, the weed control spectrum is controlled, the generation of weed drug resistance is slowed down, and the pollution to the environment is relieved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive pesticide composition with pyrenzazone, mesotrione, refined metolachlor and atrazine as active ingredients, which is suitable for controlling corn fields Annual weed. 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 maize. [0003] Mesotrione, also known as Mesotrione, is a triketone ketone herbicide as a systemic agent, absorbed through plant roots and leaves, and conducted in the body to inhibit hydroxyphenylpyruv...
