Embodiment 1

[0029] Example 1: Determination of indoor toxicity of bentazone and flunmezone-sulam on swine worms.

[0030] Test method: stem and leaf spray treatment. After 30 days of treatment, measure the fresh weight and calculate the control effect.

[0031] Herbicide combinations were evaluated according to Colby's method. Evaluation criteria: when E-E0>10%, it is synergistic; when -10%≤E-E0≤10%, it is additive; when E-E0<-10%, it is antagonistic effect.

[0032] Table 1 Determination of indoor toxicity of bentazone and flucarbazone-sulam combination on pig scorpion

[0033]

[0034]

[0035] It can be seen from the above table that the combination of bentazone and tricarbazone has obvious synergistic effect on pig worms, which can effectively reduce the dosage of pesticides and slow down the generation of weed resistance. The weight ratio of amines is 20-90:1-10; especially preferably the weight ratio of bentazone and flucarbazone is 9:1.

Abstract

The invention provides a mixed herbicide containing bentazone and triafamone and an application of the mixed herbicide. Active ingredients consist of the bentazone and the triafamone, wherein the weight ratio of the bentazone to the triafamone is (10 to 100): (1 to 30). The mixed herbicide can be applied to the control of broad-leaved weeds, Gramineae weeds and cyperus rotundus.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a mixed herbicide containing bentazone and flucarbazone and its application. Background technique [0002] Bentason is a contact-type selective post-emergence herbicide, which can be used to control broad-leaved weeds and sedge weeds in rice, wheat, soybean, corn, pea and other crop fields. Such as: flat storage, Commelina, fleas, cocklebur, Kochia, velvetleum, Maijiagong, pig scorpion, shepherd's purse, Artemisia persicae (artemisia annua), purslane, spinach, quinoa, Polygonum , black nightshade, chickweed, special-shaped sedge, broken rice sedge, ball sedge, oil sedge, sedge, Cyperus cyperus, etc. Basically ineffective against grass weeds. [0003] The mechanism of action of fluoroketone-sulam is similar to that of sulfonylurea and imidazolone herbicides, and it is effective in controlling various gramineous weeds and broad-leaved weeds such as barnyardgrass, A. Safe fo...
