Embodiment 1

[0019] Example 1: 30% monosulfuronate nicosulfuron dispersible oil suspension concentrate

[0020] 30% Monosulfuron-Nicosulfuron dispersible oil suspension concentrate consists of the following components according to the mass percentage:

[0021] Monosulfuronate 18%,

[0022] After the above components are mixed, disperse for 30 minutes under high-speed shearing, and sand-grind with a sand mill to prepare 30% monosulfuronate·nicotinesulfuron dispersible oil suspension concentrate.

Embodiment 2

[0023] Example 2: 15% monosulfuronate nicosulfuron water-dispersible granules

[0024] Monosulfurate 5%,

[0025] Each component is weighed, mixed, pulverized by an ultra-fine airflow, mixed evenly, and granulated to obtain 15% monosulfuronate·nicotinesulfuron water-dispersible granules.

Embodiment 3

[0026] Example 3: 12% monosulfuronate · nicosulfuron wettable powder

[0027] 12% Monosulfuron-Nicosulfuron wettable powder consists of the following components according to the mass percentage:

[0028] Monosulfurate 2%,

[0029] Each component was weighed, mixed uniformly, and pulverized by an ultrafine pulverizer to obtain a wettable powder of 12% monosulfuronate nicosulfuron.

Abstract

The invention provides a herbicidal composition containing monosulfuron ester, and relates to the technical field of herbicides. The active components of the herbicidal composition are monosulfuron ester and nicosulfuron, and the mass ratio of monosulfuron ester to nicosulfuron is 0.2-5:1. The herbicidal composition comprises active components (monosulfuron ester and nicosulfuron); two active components generate a synergistic effect; the using amounts of monosulfuron ester and nicosulfuron are greatly reduced; the herbicidal spectrum is enlarged, the economic cost is reduced, the drug resistance is delayed, the environment pollution is reduced, and the control effect on important weeds is obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a herbicidal composition containing monosulfurate. Background technique [0002] In the past 20 years, at least 30 countries around the world have found that different weeds have developed resistance to various types of herbicides with different chemical structures. The outstanding performance of the weed resistance problem is that the resistance formation speed is accelerated and the scope is wider. It takes more than 10 years for the herbicide varieties used in the early stage to develop resistance from the beginning of application to weeds, but recently it only takes 4 to 5 years to develop resistance. Another important performance is the increase of multi-resistance and cross-resistance. After long-term use of a single herbicide, due to changes in the environment, the composition of the weed community in farmland gradually changes, making the weeds that are les...
