Problems solved by technology

[0005] When fluroxypyr isooctyl or nicosulfuron used alone, the dosage is relatively large, the herbicidal spectrum is narrow, and it is easy to make weeds develop resistance

Embodiment 1

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

[0020] 30% fluroxypyr isooctyl nicosulfuron dispersible oil suspension concentrate consists of the following components according to the mass percentage:

[0021] Clofluroxypyr isooctyl 18%,

[0022] Nicosulfuron 12%,

[0023] Tween-65 3%,

[0024] Alkylphenol Ethoxylates NP-9 3%,

[0025] Nonylphenol ethoxylate NP-7 4%,

[0026] Corn Oil 30%,

[0027] Organic bentonite 3%,

[0028] Soybean oil methyl ester makes up the quality to 100%.

[0029] After the above components are mixed, disperse at high speed for 30 minutes, and use a sand mill to prepare 30% fluroxypyr-nicotyl-nicotinesulfuron dispersible oil suspension concentrate after sand-grinding.

Embodiment 2

[0030] Example 2: 15% isooctyl nicosulfuron-methyl water-dispersible granules of fluroxypyr

[0031] Isooctyl Fluroxypyr Acetate 5%,

[0032] Nicosulfuron 10%,

[0033] Sodium Lauryl Sulfate 5%,

[0034] Sodium Naphthalene Sulfonate 8%,

[0035] Sodium lignosulfonate 1%,

[0036] Sodium Sulfate 10%,

[0037] Diatomaceous earth makes up the mass to 100%.

[0038] The components are weighed, mixed, pulverized by an ultra-fine airflow, uniformly mixed, and granulated to obtain 15% isooctyl nicosulfuron water-dispersible granules of fluroxypyr.

Embodiment 3

[0039] Example 3: 12% isooctyl nicosulfuron wettable powder of fluroxypyr

[0040] 12% fluroxypyr isooctyl nicosulfuron wettable powder consists of the following components according to the mass percentage:

[0041] Clofluroxypyr isooctyl 2%,

[0042] Nicosulfuron 10%,

[0043] Sodium Lauryl Sulfate 10%,

[0044] Sodium lignosulfonate 5%,

[0045] Silica 10%,

[0046] Kaolin makes up the mass to 100%.

[0047] Each component was weighed, mixed uniformly, and pulverized by an ultrafine pulverizer to obtain 12% fluroxypyr-isooctyl-nicotinesulfuron wettable powder.

Abstract

The invention provides a weeding composition containing nicosulfuron and relates to the technical field of pesticide herbicide. Active ingredients of the weeding composition are fluroxypyr-mepthyl and nicosulfuron according to a mass ratio of 0.2-5:1. The weeding composition contains the active ingredients, fluroxypyr-mepthyl and nicosulfuron which are synergistic, so that consumption of fluroxypyr-mepthyl and nicosulfuron is reduced remarkably, weeding spectrum is expanded, economic cost is saved, resistance development is slowed down, environment pollution is reduced, and prevention and control effect on important weed can be improved remarkably.

Description

technical field [0001] The invention relates to the technical field of pesticide herbicides, in particular to a herbicidal composition containing nicosulfuron. 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 less...
