Description

Herbicide for Goryeo grass {Herbicide for Zoysia japonica}

The present invention removes annual and perennial broadleaf and coniferous weeds occurring in all lawns (playgrounds, parks, park cemeteries, individual cemeteries, public green spaces) including Korea grass (Zoysia japonica), that is, the native grass of Korea To herbicides.

There are about 200,000 plant species known to date, and about 200 plant species are regarded as double weeds, 70 of which are broadleaf or coniferous weeds that are a problem in lawns. These weeds have a lot of difference in the time of occurrence and control method according to their characteristics, and many grass herbicides that have been pre-registered have a narrow range of herbicide even though they are sprayed. There is a problem.

One of the most frequently encountered problems in grass weeding is a weak phenomenon, which is mainly caused by the application of a wider range of application without disregarding the exact characteristics of the herbicide or by the uneven application of the herbicide.

In conventional weed control operations, two or more types of herbicides are mixed and used to efficiently control various types of weeds. Among them, the typical application is Patent Application No. 10-2003-0046358, and its configuration is as follows.

2.5 to 5.0 g of plazasulfron, 50 to 100 ml of mecoprop, 37 to 74 ml of triclopyr-TEA, pendimethalin (pendimethalin) based on the weight of the active ingredient per 200 l of water ) 200-225 ml, electrodeposition 60-120 ml, 150-200 g of urea fertilizer (46% nitrogen content) and 150-200 g of chelated iron fertilizer (EDTA-Fe).

However, the conventional herbicide of the above-described configuration is a herbicide containing nutrients (nitrogen) has a problem that can not remove both the broadleaf and coniferous weeds of the lawn because the herbicidal ability is removed, the weeds that can not be removed by the herbicide must be removed by the attraction force There is a problem.

An object of the present invention for solving the above problems is to provide a herbicide for Korea grass that can remove all the broadleaf and coniferous weeds of the lawn by a single spray to efficiently manage the lawn of the lawn.

The solution of the present invention is a herbicide that can remove both broadleaf and coniferous weeds on the lawn, based on the weight of the active ingredient per 20 liters of water, 10-15 g of Plazasulfuron, 20-25 ml of oxyfluorfen. , 15-20 ml of Fluazifop-p-butyl, 60-65 ml of Triclopyr, 25-35 weight ml of surfactant.

The herbicide for grass turf of the present invention as described above has the effect of efficiently managing the lawn of the lawn by removing all the annual and perennial broadleaf and coniferous weeds of the lawn by one spray.

Plazasulfuron in the grass herbicide of the present invention to achieve the above effect is effective in perennial weeds such as shamrock, persimmon and perennial weeds such as poaful, and oxyfluorfen so that weeds do not germinate. It is sprayed before weed germination and has a long duration.

Fluazifop-p-butyl is effective for 1-year broadleaf weed weeds, and it is preferable to use it in 3-5 weeds, while Triclopyr is annual and perennial broadleaf weeds. The surfactant acts to enhance the adhesion by making the components well dissolved in water and improving permeability, eczema and the like.

Hereinafter, the present invention will be described with reference to Examples.

Table 1 below shows the most preferred amount of active ingredient per 20 liters of water.
