KR-102959844-B1 - ECO-FRIENDLY HERBICIDAL COMPOSITION FOR WEED CONTROL AND METHOD FOR IMPROVING GROWING ENVIRONMENT USING SAME

Abstract

The present invention relates to an eco-friendly herbicidal composition capable of easily controlling both broadleaf weeds (dicots), grass weeds (monocots), and sedge weeds among the weeds that proliferate in Korean turfgrass, and a method for improving the turfgrass growth environment using the same. The eco-friendly herbicide composition, based on the weight of the active ingredient per 200 liters of water, 8 to 16 ml of nicosulfuron, oxadiazon + pendimethalin 110 to 120 ml, 190 to 210 ml of mecoprop, 35 to 37 ml of triclopyr-TEA, It is characterized by including 30 to 50 ml of electrodeposition agent. A method for improving the turf growth environment is to spray the above-mentioned eco-friendly herbicide composition in an amount of 150 to 250 ml per 1 m² of turf.

Description

Eco-friendly herbicidal composition capable of controlling both broadleaf weeds and grass weeds in Korean turfgrass and method for improving turfgrass growth environment using the same The present invention relates to an eco-friendly herbicide composition capable of controlling both broadleaf weeds and grass weeds in Korean turfgrass and a method for improving the turfgrass growth environment using the same. More specifically, the invention relates to an eco-friendly herbicide composition capable of easily controlling both broadleaf weeds (dicots), grass weeds (monocots), and sedge weeds among the weeds that proliferate in Korean turfgrass, and a method for improving the turfgrass growth environment using the same. Furthermore, the present invention relates to an eco-friendly herbicide composition capable of controlling both broadleaf weeds and grass weeds within Korean turfgrass, which is not limited to broadleaf weeds among weeds propagating in Korean turfgrass but can also remove overwintering weeds as well as grass weeds and sedge weeds, and which can be used at any time of the year, as well as a method for improving the turfgrass growth environment using the same. High-quality turf or lawns are essential not only in the golf industry but are also being created in various fields such as parks, public or private gardens, recreational facilities, sports fields or stadiums (horse racing, football, baseball, hockey, tennis), flower gardens, and ornamental gardens. For efficient management of the turf and effective weed removal, when spraying chemicals, factors such as not affecting the life of the turf, not causing damage to surrounding landscaping trees, being economical, and having good aesthetics must be satisfied. Globally, there are about 1,800 known species of weeds that occur in agricultural land, and in Korea, 461 species of weeds are known, while the number of weeds targeted for control in Korean lawn grass is known to be around 50 to 70 species. With the recent increase in the golf population and the establishment of golf courses across the country, attention is being drawn to the issue of environmental pollution caused by chemical substances, such as pesticides, used for the maintenance and management of golf course greens. The problem in maintaining the aesthetics of such grass or lawns and growing them healthily is the removal of weeds. Weeds that proliferate on the grass inhibit its growth, suppress the grass, cause it to wither, become a breeding ground for pests and diseases, and if their seeds adhere to clothing, they can cause health problems for users. Therefore, it has been practiced for a long time to use herbicides to remove weeds that grow on the lawn. Generally, a herbicide refers to a chemical used to control weeds, which are plants that compete with crops for growth by depleting nutrients required by crops or creating unfavorable growing environments. Since the development of MCPA as a herbicide, various other herbicides have been developed and are in use. Herbicides are classified according to their action characteristics into non-selective herbicides, which kill all plants in the sprayed area, and selective herbicides, which kill only specific plant species and can be used to control weeds during crop cultivation. In addition, according to their mechanism of action, they are classified into photosynthetic inhibitors (inhibition of electron transfer, inhibition of chlorophyll production, inhibition of photosynthesis involving yellow pigment, inhibition of photosynthesis by the generation of reactive oxygen species, etc.), energy production inhibitors, plant hormone action inhibitors, protein biosynthetic inhibitors, cell division inhibitors, amino acid biosynthetic inhibitors, and fatty acid synthesis inhibitors. Improper use of herbicides during turf cultivation can cause phytotoxicity, so they must be applied cautiously by considering selectivity and timing; however, the high volume of pesticide use has become a global issue due to concerns about soil contamination caused by overuse. Furthermore, it is reported that the species of weeds in lawns are becoming increasingly diverse, and resistance to some herbicides is even appearing. For the reasons mentioned above, conventional herbicides had a narrow spray spectrum resulting in insufficient control efficacy. Furthermore, because they had to be sprayed multiple times depending on the weed species, the problem of overuse persisted, and management was difficult due to increased maintenance costs. Due to these issues, it is common practice to manage lawn weeds by manual weeding once they appear; however, managing them individually by manual weeding is difficult, and because weeds have very strong reproductive capabilities due to their physiological characteristics, they grow back quickly even after weeding, making it difficult to maintain a clean environment. For the reasons stated above, the inventor of the present invention has pr
