Embodiment 1

[0029] Example 1: Determination of the indoor virulence of promethazine and quinclorone against D. chinensis.

[0030] Test method: Choose a weed with consistent growth, D. chinensis, for colonization, and do stem and leaf treatment. After the leaves are dried, spray the stem and leaves with water. After 30 days of treatment, the fresh weight was measured and the control effect was calculated.

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

[0034]

[0035] It can be seen from the above table that the combination of trisulfuron-methyl and quinclorone has obvious synergistic effect on D. chinensis, which can effectively reduce the dosage of pesticides and slow down...

Abstract

The invention provides a mixed herbicide containing propyrisulfuron and dichloroquinolone and an application thereof. The mixed herbicide contains active components of the propyrisulfuron and the dichloroquinolone; the weight ratio of the propyrisulfuron to the dichloroquinolone is 1-10:1-40. The mixed herbicide provided by the invention can be used for controlling broadleaf weeds, gramineous weeds and nutgrass flatsedge.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a mixed herbicide containing promethazine and quinclorone and application thereof. Background technique [0002] Trisulfuron-methyl is a pyrimidine-based sulfonylurea herbicide developed by Japan's Sumitomo Chemical. Although it has the same mechanism of action as other sulfonylurea herbicides, it is an acetolactate synthase (ALS) inhibitor, but it is resistant to sulfonylureas. Urea herbicides have good weed control effects, and are mainly used in paddy fields to control grass and broadleaf weeds. The product is low in dosage and has a good control effect on some weeds that are known to be resistant to sulfonylurea herbicides. [0003] Dichloroquinazone is a new type of herbicide independently developed by my country. It is an HPPD inhibitor. Its function is characterized by the absorption and conduction of weed roots and leaves. After the sensitive weeds absorb this drug, it inhibits...
