More particularly, the present invention relates to a method of herbicide- The present invention relates to an eco-friendly herbicidal composition which can be used in a golf course green, and a method for improving a grass growth environment using the same.

Recently, with the increase in the golf population and the establishment of golf courses in various places, attention has been paid to the problem that chemical substances such as agricultural chemicals used for maintenance and maintenance of the golf course green cause environmental pollution of the green.

High quality grass or lawn is essential in the golf industry.

It is the removal of weeds that is problematic in the process of healthy growth of the lawn while maintaining the aesthetics of such lawns or lawns. The weed growing on the lawns inhibits the growth of lawns. If the seeds are adhered to clothing, it may become a problem to the health of the user.

Thus, herbicides have conventionally been used to remove weeds from turfgrass, but the use of pesticides worldwide has become a problem because of concern about soil contamination due to excessive use of herbicides. In addition, it has been reported that the weed species in the lawn are becoming more diverse and some herbicides are tolerant.

For the above reasons, conventional herbicides have a problem that the spraying effect is insufficient due to a narrow spray spectrum, and since they have to be sprayed several times according to the weed species, there is a problem of overuse of the preparation agent and maintenance cost is increased .

Because of these problems, it is common to manage with grass weeding after grass weeds, but it is difficult to manage them individually because of human herb weeding. Due to the physiological characteristics of weeds, weeds that grow very quickly after weeding are difficult to clean there was.

For the above reasons, the applicant of the present invention has proposed a method for improving the environment for improving the grass growth environment using the composition described in Patent Registration No. 10-1190596 (composition for improving environmental grass growth environment and method for improving grass growth environment thereof) and Patent Registration No. 10-1206108 Method) and filed and registered.

In the registered patent, two or more kinds of herbicides are mixedly used in order to efficiently control various kinds of weeds in an operation for controlling grass weeds.

However, when the method disclosed in the registered patent is applied, most of the weeds are weeded, but the removal of the weed (weed) from the green of the golf course is not achieved to a desired level.

The inventors of the present invention have conducted intensive studies and have found that it is possible to efficiently control the weed control of the grassy weeds in the green of the golf course while not affecting microorganisms, ants and earthworms living in the soil, A herbicide composition usable for a golf course green was completed.

According to another aspect of the present invention,

The present invention provides a method for improving grass growth environment using an environmentally friendly herbicidal composition usable in a golf course green, comprising spraying the environmentally friendly herbicidal composition in an amount of 150 to 250 ml per 1 m ² of lawn.

The application of the eco-friendly herbicidal composition usable in the golf green of the present invention as described above and the improvement method of the grass growth environment using the grass as described above can be safely applied to microorganisms, ants and earthworms living in grass and surrounding landscaping trees and soil, So that high-quality lawns or lawns can be formed.

In addition, by adding the electrodeposition agent and spraying using a high-pressure atomizer, the adsorbent is uniformly and strongly adsorbed on the surface of the weeds and the soil, thereby reducing the loss of the active ingredient, and the efficacy of the spray can be maintained for a long time.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described in detail below.

However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims.

Also, terms used herein are for the purpose of illustrating embodiments and are not intended to limit the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. &Quot; comprises "and / or" comprising "used in the specification do not exclude the presence or addition of components other than the components mentioned. Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense commonly understood by one of ordinary skill in the art to which this invention belongs.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The eco-friendly herbicidal composition usable in the golf green of the present invention comprises 7 to 9 g of flucetosulfuron, 5 to 7 g of pyrazosulfuron-ethyl, 1.7 to 2.7 ml of carfentrazone-ethyl, 40 to 60 ml of mecoprop and 90 to 110 ml of an electrodeposition agent.

Specifically, 8 g of flucetosulfuron, 6 g of pyrazosulfuron-ethyl, 2.24 ml of carfentrazone-ethyl, 200 g of methoprole 50 ml of mecoprop, and 100 ml of an electrodeposition agent.

In the present invention, the term "environmentally friendly" means that the environmentally friendly herbicidal composition according to the present invention is used in combination with a natural environment without polluting the natural environment. By using a minimum amount of herbicides in combination, It has excellent herbicidal effect on the removal of weedy weeds while maintaining safety to grass and surrounding landscape trees without affecting them.

The flutosulfuron and pyrazosulfuron-ethyl exhibit a herbicidal effect by inhibiting amino acid biosynthesis of the plant. Specifically, it is a sulfonylurea herbicide, which is a selective penetration planet that is absorbed by the roots and leaves of a plant and is involved in the biosynthesis of valine, an essential amino acid of plants, and isoleucine Inhibits the activity of acetolactate synthase (ALS), which inhibits cell division and plant growth, thereby controlling weeds. Lawna is marketed under the trade name.

Carfentrazone-ethyl acts as a photophorhyrinogen oxidase inhibitor or protox inhibitor for light leaf weeds. It is rapidly absorbed through the leaves of plants and produces an enzyme called Photophorhyrinogen oxidase, which is involved in the production of chlorophyll. It inhibits and breaks down the cell membrane, so it acts fast. It is available under the trade name Ace Ace.

The above-mentioned mecoprop is used for light leaf weeds such as Crova, has high stability on lawn, inhibits plant growth hormone, and is fast in the plant body, so that the effect of treating foliage is fast.

However, when used, it is necessary to use an appropriate amount because it may cause problems such as leaf curl and tree leaves. It is commercially available under the trade name MC Pipi (MCPP).

The electrodeposition agent may further be used as a pesticide auxiliary agent, a combination of a polyoxyethylene alkylaryl ether and a sodium lignosulfonate. The electrodeposition eliminates the water droplet on the surface of the weeds, thereby allowing the composition of the present invention to be uniformly and strongly adsorbed on the surface of weeds and soils, preventing the composition from flowing down during rainfall, Do it.

In the present invention, the herbicidal composition usable for golf green as above is sprayed in an amount of 150 to 250 ml per m ² of the lawn.

The spraying method is as follows: a high-pressure sprayer 130A is connected to a PTO of a one-ton truck equipped with a PTO (power transmission device), and a high-pressure hose of 8.5 mm is connected to a high- 900 to 1,100 rpm, and the high-pressure sprayer 130A at a pressure of 15 to 25 kg / cm2.

At this time, in order to speed up the operation, it is preferable to spread while advancing to 200 m / hour.

By spraying 2,000 L of the herbicidal composition, which can be used in the golf course green of the present invention, in the range of 10,000 m 2 on the lawn, 200 ml per 1 m 2 of lawn can be sprayed, thereby maximizing the effect of improving the grass growth environment. If it is out of the range of 150 ml to 250 ml per 1 m 2 of lawn, the effect of improving the grass growth environment may be deteriorated, or damage to lawn or landscape trees may occur.

Hereinafter, the present invention will be described in more detail with reference to the following examples.
