Problems solved by technology

However, when two or more herbicidal active substances are mixed, the synergistic effect of herbicides is extremely limited. Instead, due to the differences in herbicidal properties, absorption, migration or objects of the two herbicides, it is different from single-agent treatment. Compared with the low herbicidal activity

Embodiment 1

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

[0079] Purpose of the test

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

[0081] Test method

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

[0083] 2. Occurrence of target weeds: weeds such as barnyardgrass, annunum, amaranth, humulus, lettuce, mugwort, sorrel wrinkle leaf, creeping wheatgrass, white aster, etc., so as to fully judge the weeding effect.

[0084] Processing content

[0085]As shown in Table 1 below, a mixture of diquat dibromide (10-20% by weight) and glufosinate-ammonium (2-10% by weight) is used as the main component, and 2% by weight of propylene glycol (Propyle...

Embodiment 2

[0166] According to the composition of the herbicide mixture (the mixture of diquat dibromide and glufosinate-ammonium) of the present invention Comparison of quick effect of combined control

[0167] In this experiment, the effect of the herbicide was increased in the greenhouse environment, so the herbicide was used according to the ratio of the reduced fields. The rates tested were chosen in such a way that when the herbicides were used alone they controlled about 50 to 70%, so that when the mixtures were tested, any synergistic effect could be easily detected. The same test conditions as in Example 1 above were used.

[0168] Prepare diquat dibromide and glufosinate-ammonium mixture with different combination ratio

[0169] The present inventors proved that in order to increase the quick-acting effect together with the persistence of the herbicide in the above-mentioned Example 1, it is useful to use a mixture of diquat dibromide and glufosinate-ammonium as a non-s...

Embodiment 3

[0192] According to the composition of the herbicide mixture (the mixture of diquat dibromide and glufosinate-ammonium) of the present invention Comparison of the quick effect of combined prevention and control_practical pavement cultivation

[0193] In this experiment, a comparative experiment was carried out on the control quick effect of the composition ratio of the herbicide mixture according to the present invention on the actual road surface. In this experiment, the herbicides were tested by different combination ratios. In order to find the herbicide combination ratio that expresses the most excellent quick-acting properties, each experimental group maintained the same environmental conditions (sunlight transmission amount (light amount), water content, etc.) , soil, etc.).

[0194] In order to maintain the same amount of light transmission, the test was carried out in the center of the open field where no trees, buildings, slopes, etc. would affect the surrounding ...

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...
