Embodiment approach

[0034] As a particularly preferred embodiment of the present invention, the herbicide composition contains clethodim, clopyralid and amiloride, and the content of clethodim is 0.5 parts by weight relative to clethodim. -1.5 parts by weight, the content of amiloride is 0.05-0.35 parts by weight; the herbicide composition also contains fatty alcohol polyoxyethylene ether, sorbitan polyoxyethylene ether, organic bentonite and methyl oleate; The ratio of the total weight of clethodim, clopyralid and amiloride to fatty alcohol polyoxyethylene ether, sorbitan polyoxyethylene ether, organic bentonite and methyl oleate is 1: (0.2-0.8) :(0.1-0.4):(0.04-0.16):(1.5-6). In the case of this preferred embodiment, the herbicide composition is particularly suitable for the control of field weeds in oilseed rape, and has a wider weed killing spectrum and higher killing and controlling effects.

[0035] In the present invention, fatty alcohol polyoxyethylene ether such as R-O-(CH 2 CH 2 O) ...

Embodiment 1

[0046] In this example, a herbicide composition was prepared in the form of an oil suspension.

[0047] Get 10 parts by weight of clethodim, 8 parts by weight of clopyralid, 2 parts by weight of amiloride, 10 parts by weight of fatty alcohol polyoxyethylene ether, 5 parts by weight of sorbitan polyoxyethylene ether , 2 parts by weight of organic bentonite and 63 parts by weight of methyl oleate were mixed uniformly to obtain the herbicide composition of the present embodiment.

Embodiment 2

[0049] In this example, a herbicide composition was prepared in the form of an oil suspension.

[0050] Get 10.9 parts by weight of clethodim, 5.4 parts by weight of clopyralid, 3.7 parts by weight of amiloride, 10 parts by weight of fatty alcohol polyoxyethylene ether, 5 parts by weight of sorbitan polyoxyethylene ether , 2 parts by weight of organic bentonite and 63 parts by weight of methyl oleate were mixed uniformly to obtain the herbicide composition of the present embodiment.

Abstract

The invention discloses a herbicide composition; the herbicide composition comprises clethodim, clopyralid and picloram; with respect to 1 weight part of clethodim, the content of the clopyralid accounts for 0.01 to 50 parts by weight, and the content of the picloram accounts for 0.001 to 15 parts by weight. The invention further provides the usage of the herbicide composition in preventing and removing weeds in fields of crops.Through the adoption of the technical scheme, the effects of the clethodim, the clopyralid and the picloram in the herbicide composition can be effectively increased, so that the efficacy of the herbicide composition is improved.

Description

Technical field [0001] The present invention relates to the field of agriculture, in particular, to a herbicide composition and the use of the herbicide composition. Background technique [0002] Rapeseed is the most important oil crop in my country. Since 1985, my country's rapeseed planting area and total output have ranked first in the world, accounting for about 30% of the world's rapeseed planting area and total output. It occupies a prominent position in the international rapeseed industry. At the same time, rapeseed is also one of the edible oils in my country. The main source of vegetable oil. [0003] Affected by the climate, environment and diversified cultivation methods in various places, weeds in rape fields are relatively complex, causing serious weed damage and difficult to control. In recent years, the number of weed species in rapeseed fields has been increasing. Because they compete with crops for fertilizer, water, sunlight, space, etc., they have a seriou...
