Embodiment 1

[0076] Example 1: 21% flazasulfuron·flupyroxyacetic acid wettable powder (20:1)

[0077]

[0078] Preparation method: According to the above formula, the active ingredients flazasulfuron, fluroxypyr, auxiliaries and fillers are mixed, mechanically pulverized, and then pulverized by airflow, and mixed uniformly to prepare the corresponding wettable powder pesticide.

Embodiment 2

[0088] Example 2: 12% flazasulfuron·flupyroxyacetic acid microemulsion (5:1)

[0089]

[0090] Preparation: Mix the original medicine, adjuvant and water into a homogeneous phase.

Embodiment 3

[0098] Example 3: 14% flazasulfuron · fluroxypyr oil suspension concentrate (1:1)

Abstract

The invention discloses a herbicidal composition and its application, and relates to the technical field of pesticide compounding. The active ingredients of the herbicidal composition include component A and component B; wherein A is azosulfuron-methyl or a salt thereof, and B is any one or more of a pyridine carboxylic acid herbicide or a salt thereof; The weight ratio of component A to component B is 20:1 to 1:300. The herbicidal composition of the present invention has four characteristics: 1. The composition can effectively reduce the application amount of each single agent, has fast effect, long duration of effect, and delays the resistance of plants; 2. The composition can be highly efficient It has a synergistic effect in controlling older broadleaf weeds, sedges and gramineous weeds with less than 7 leaves; 3. The composition can expand the herbicidal spectrum; 4. The composition is highly safe for lawns.

Description

Technical field [0001] The invention belongs to the technical field of pesticide compounding and relates to herbicidal compositions and their applications. Background technique [0002] With the rapid development of the economy, people have higher and higher requirements for urban greening, and the domestic lawn area is also constantly increasing. The prevention and control of weeds in lawns has become the biggest problem for lawn managers. At present, weeds in lawns are mostly removed manually, which requires high investment, low efficiency and poor results. Spraying safe and effective herbicides is an effective way to control lawn weeds. [0003] Flazasulfuron, the English name is flazasulfuron, the chemical name is 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridinesulfonyl)urea, molecular weight is 407.32, and the chemical formula is C 13 H 12 F 3 N 5 O 5 S, its structure is shown in formula (I). The agent can be quickly absorbed by the stems, leaves ...
