Example Embodiment

[0077]

[0078] The control effect test of the herbicide mixture of the present invention (mixture of diquat dibromide and glufosinate-ammonium) on annual weeds and perennial weeds in non-agricultural land

[0079] Test purpose

[0080] The purpose of this study is to select the excellent control agents for annual weeds and perennial weeds in non-agricultural land and the expression mechanism of drug efficacy in specific areas.

[0081] Test method

[0082] 1. Object weeds: annual weeds and perennial weeds in non-agricultural land

[0083] 2. The occurrence of the target weeds: barnyard tares, amaranth, amaranth, humulus japonicus, thorn lettuce, wormwood, sorrel, creeping ice grass, white aster, etc. are produced, so as to fully judge the weeding effect.

[0084] Processing content

[0085]As shown in Table 1 below, a mixture of diquat dibromide (10 to 20 wt %) and glufosinate (2 to 10 wt %) is used as the main component, and 2 wt % of propylene glycol is also m...

[0166] Composition of the herbicide mixture according to the present invention (mixture of diquat dibromide and glufosinate-ammonium) Comparison of quick-acting effects of combined control

[0167] In this experiment, the effect of herbicides was increased in a greenhouse environment, so herbicides were used according to the ratio of the fields reduced. The ratios tested are chosen in such a way that when the herbicides are used alone about 50 to 70% control, all synergistic effects can be easily detected when the mixture is tested. The same test conditions as in Example 1 above were used.

[0168] Prepare a combination of diquat dibromide and glufosinate-ammonium mixture with different ratios

[0169] The present inventors have proved that in order to increase the quick-acting effect together with the sustainability of the herbicide in the above-mentioned Example 1, a mixture of diquat dibromide and glufosinate, which is a non-selective herbicide, is useful...

[0192] Composition of the herbicide mixture according to the present invention (mixture of diquat dibromide and glufosinate-ammonium) Comparison of quick-acting effects of combined prevention and control_Actual road cultivation

[0193] In this experiment, a comparative experiment was carried out on the control quick effect of the combination ratio of the constituent components of the herbicide mixture according to the present invention in an actual road surface. In this experiment, the herbicides were tested according to each combination ratio. In order to find the herbicide combination ratio that expresses the most excellent quick-acting effect among them, each experimental group maintained the same environmental conditions (sunlight transmittance (light amount), moisture content) , soil, etc.).

[0194] In order to maintain the same amount of light transmission, the test was carried out in the middle of the open field, which did not have any influence because...

Abstract

The present invention relates to a herbicide mixture having a synergistic action, and more particularly, to a synergistic herbicide mixture including: diquat dibromide and nonselective herbicide; a herbicide composition including the herbicide mixture as an active ingredient; and a weed control method using same. The herbicide mixture of the present invention is characterized in that diquat dibromide and glufosinate ammonium are mixed at a certain ratio, thereby showing 80% or more of a herbicidal effect on various weeds and plants, and a herbicidal activity lasting at least 30 days, as well as a rapid herbicidal activity of 6 to 23 hours (within one day), on average, on a road surface on which an average actual light irradiation is actively performed. Thus, the herbicide mixture has an advantage in that a synergistic effect is obtained during use (which cannot be expected to compare the case of a single drug in which diquat dibromide and glufosinate ammonium are separately used). In particular, due to a difference in the action mechanisms of diquat dibromide and glufosinate ammonium, diquat dibromide, at the same time, allows for drug efficacy following treatment to be promptly exhibited, and glufosinate ammonium allows for weeds in shaded areas without sunshine to be removed. Further, since the combined drug has a duration of efficacy of at least 30 days, as well as a fast-acting property exhibited within a day after treatment, after one control application, there is no need to use a herbicide for a long period of time. Thus, the combined drug is effective in reducing the amount of agricultural chemicals that would otherwise be used.

Description

technical field [0001] The present invention relates to a synergistic herbicide mixture, more particularly to a synergistic herbicide mixture comprising diquat dibromide dibromide and a non-selective herbicide; a herbicide comprising said herbicide mixture as a main component mixtures; and methods of weed control utilizing the same. Background technique [0002] In agriculture and field management, the protection of crops from weeds and other plant hazards is an ongoing problem for professional use in the home and garden. Also, in the case of grass growing in places such as golf courses, lawns, and parks, it can be said that the removal of such unnecessary weeds and plants is very important in terms of aesthetics. To help address this problem, researchers in the field of synthetic chemistry offer a wide and diverse range of chemical substances and chemical formulations that are effective in the inhibition of this unwanted growth. A variety of chemical herbicides with vario...
