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: Indoor toxicity test results of memetrazone, thiazone-methyl, benzonitrile herbicide bromoxynil and their compounded crabgrass (Digitaria sanguinalis) and Abutilon theophrasti.

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

[0017]

[0018] In the formula:

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

[0020] B is the fresh weight inhibitory rate of thiazosulfuron-methyl to the target weeds when a certain dose is used alone;

[0021] C is the fresh weight inhibition rate of benzonitrile herbicides (bromoxynil octanoyl or one of bromoxynil) to target weeds when a certain dose is used alone;

[0022] n is the number of mixed herbicide varieties;

[0023] E. 0 It is the theoretical value of the inhibition rate of the fresh weight of the target weeds when the three medicaments of fenpyrazone, thiazone-met...

Embodiment 2

[0032] Example 2: 35% memetrazone-thiazone-methyl-octanoyl bromoxynil water-dispersible granules.

[0033]

[0034] 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 35% meprafen-thiazone-methyl-octanoyl bromide Benzonitrile water dispersible granules.

Embodiment 3

[0035] Example 3: Wettable powder of meprafen-thensulfuron-methyl-octanoyl bromoxynil.

[0036]

[0037] 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 Metrametrazone Thicarbazone-methyl-octanoyl Bromoxynil WP.

Abstract

The invention discloses a pesticide composition containing metramezone, thiazone-methyl and benzonitrile herbicides. The nitrile herbicide is selected from one of octanoyl bromoxynil or bromoxynil; the herbicidal composition of the present invention has a significant synergistic effect, and the effect of controlling annual weeds in cornfields is obviously better than that of each single agent used alone, combined The dosage of the effective ingredients of the herb is significantly less than that used alone, and the herbicidal spectrum is expanded, the emergence of weed resistance is delayed, and the pollution to the environment is reduced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a synergistic responsive pesticide composition with metrametrazone, thionsulfuron-methyl and benzonitrile herbicides as active ingredients, which is suitable for controlling annual weeds 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 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 to corn, and is mainly used to control annual grasses in corn fields Grasses and some broadleaf weeds. [0003] Thiencarbazone-methyl is a sulfonylaminocarbonyl triazolinone herbicide and an acetolacta...
