If the amount is less than 100 parts by weight Izaquine weed foliage removal effect, but the effect of removing even the root is reduced, if more than 125 parts by weight adversely affect the growth of grass.

The herbicide composition of the present invention includes mecoprop-p. Mecoprop-Phi is a phenoxy herbicide, a selective herbicide that is treated on the foliage of annual and perennial broadleaf weeds after weeding. It is absorbed through the roots and foliage of broadleaf plants and is active in the meristem of plants. . In addition, disturbing the balance of auxin in vivo is known to exhibit herbicidal activity by disturbing the basic physiological functions of plants such as activation of meristem, abnormal division, inhibition of chlorophyll formation, and increase of osmotic pressure of cell membrane. Mecoprop-P is a commercial herbicide of such phenoxy clock herbicides and is currently marketed under the trade name, and in the case of the conventional dilution to 200 parts by weight based on 100 parts by weight of water for a sufficient herbicidal effect, in the present invention Mecoprop-P is used at a level of 75 to 100 parts by weight, preferably 75 parts by weight, relative to 100 parts by weight of water. Mecoprope-blood less than 75 parts by weight has no effect of removing weed foliage and roots, and the duration of the drug is shortened. If it exceeds 100 parts by weight, the surrounding trees are adversely affected.

The herbicide composition of the present invention comprises bentazon. Ventazone is marketed under the trade name Bassagreen M60 as a herbicide for removing broadleaf weeds, and in the present invention, 15 to 20 parts by weight, preferably 15 parts by weight, is used with respect to 100 parts by weight of water. If the amount of ventazone is less than 15 parts by weight, weed removal effect is shortened, but the drug duration is shortened. If it exceeds 20 parts by weight, turf growth is adversely affected.

The herbicide composition of the present invention comprises fenoxaprop-p-ethyl. Phenoxaprop-P-ethyl is a herbicide known to remove flowers and weeds, and is currently marketed under the trade name Medsi. In the past, it was diluted to 100 parts by weight based on 100 parts by weight of water. This phenoxaprop-p-ethyl is used at a level of 40 to 50 parts by weight, preferably 40 parts by weight, based on 100 parts by weight of water. If the phenoxaprop-P-ethyl is less than 40 parts by weight, the weed removal effect is lowered. If it exceeds 50 parts by weight, the surrounding trees are adversely affected.

The herbicide composition of the present invention comprises a siloxane. Siloxane is a component that enhances the penetrating power of the active ingredient, and is currently marketed under the trade name Silhouette. In the present invention, the siloxane is used in an amount of 32 to 35 parts by weight, preferably 34 parts by weight based on 100 parts by weight of water. If the siloxane is less than 32 parts by weight, the effect of being absorbed by the weed foliage is lowered, and if it exceeds 35 parts by weight, browning of the grass leaves appears.

The herbicide composition of the present invention comprises a neutral fertilizer. The neutral fertilizer is a mixture of nitrogen, phosphoric acid, potassium to form a neutral, and serves to prevent acidification of the soil and to provide nutrients to the grass. In the present invention, 175 to 225 parts by weight, preferably 200 parts by weight based on 100 parts by weight of water. If the neutral fertilizer is less than 175 parts by weight causes problems in the nutrition of the grass, if it exceeds 225 parts by weight of overnutrition causes weed activity.

On the other hand, the herbicide composition of the present invention may further contain an active ingredient selected from antidote, fungicide, insecticide and tick insecticide in the range which does not inhibit the purpose of the herbicide composition of the present invention in addition to the above components.
