Embodiment 1

[0033] Example 1: pyrazosulfuron-methyl, mefentrazone and their compound pairs Cirsium setosum (Cirsium setosum, CIRSE=little thistle), Abutilon theophrasti (ABUTH=abutilon), and pigsweed (Galium aparine, GALAP= Endotoxicity determination test of swine scorpion.

[0034] According to the Gowing method to evaluate the combination of herbicides (NY / T 1155.7-2006), the formula is as follows:

[0035] E 0 = X + Y - X × Y 100

[0036] In the formula:

[0037] X is the inhibitory rate of pyrazosulfuron-methyl to the fresh weight of target weeds when a certain dose is used alone;

[0038] Y is the fresh weight inhibition rate of target weeds when mefentrazone is used alone at a certain dose;

[0039] E. 0 It is the theoretical value or expected value of the inhibition rate of fresh weight of target weeds when ...

Embodiment 2

[0045] Embodiment 2: (Pyrazosulfuron-metazone water-dispersible granule)

[0046]

[0047] 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, dry and sieve to obtain the corresponding weight percentage of pyrazosulfuron-metsutrazone water-dispersible granules agent.

Embodiment 3

[0048] Embodiment 3: (pyrazosulfuron-metazone wettable powder)

[0049]

[0050] 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 pyrazosulfuron-metazone wettable powder.

Abstract

The invention relates to a pesticide composition containing metazosulfuron and carfentrazone-ethyl. Active ingredients of the pesticide composition are metazosulfuron and carfentrazone-ethyl, and the rest is pesticide adjuvant. According to the invention, weed control spectrum is broadened. The composition has a synergistic effect on a target. An excellent solution can be provided for controlling of broadleaved weeds in wheat fields. The pesticide composition is of positive significance for comprehensive control of weeds.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive pesticide composition with pyrazosulfuron-methyl and mefentrazone as active ingredients, which is suitable for controlling annual broad-leaved weeds in wheat fields. Background technique [0002] Metazosulfuron (metazosulfuron), a sulfonylurea herbicide developed by Nissan Chemical, is mainly used to control annual broad-leaved weeds and some gramineous weeds such as crabgrass and barnyard grass in wheat fields and rice fields. Broad-leaved weeds such as hemp, amaranth, dwarf arrowhead, and thistle have good control effects. [0003] Carfentrazone-ethyl is a triazolinone herbicide developed by FMC. It inhibits protoporphyrinogen oxidase and leads to the accumulation of toxic intermediates, thereby destroying the cell membrane of weeds and causing the leaves to dry up and die quickly. . Profentrazone-ethyl is absorbed by plant leaves withi...
