Description

제초제 조성물{HERBICIDAL COMPOSITION} Herbicide composition {HERBICIDAL COMPOSITION}

본 발명은 제초제 조성물에 관한 것이다. The present invention relates to herbicidal compositions.

작물의 재배 기술에 있어서 작물의 성장을 저해하는 잡초를 방제하여 작물을 보호하는 것은 중요하다. 작물의 재배지에서 발생한 잡초에 의한 작물의 생육 부진 또는 수량 감소와 같은 피해를 줄이기 위하여, 이들을 효과적으로 방제할 수 있고 작물에는 안전한 제초 활성 물질들이 개발되어왔다. 현재까지 개발된 다수의 제초제들은 특정 작물용으로 등록되어 잡초 방제용으로 사용되고 있다. 이러한 특정 작물의 재배지에서 발생하는 잡초의 방제용으로 사용하기 위한 제초제는 제초 활성이 높고, 폭넓은 제초 스펙트럼(spectrum)을 가지되, 환경 및 작물에는 안전한 것이 바람직하다. 그러나 모든 제초제들이 이러한 조건을 완벽히 충족시키는 것은 아니다. In crop cultivation technology, it is important to protect crops by controlling weeds that hinder crop growth. In order to reduce damage such as sluggish growth or decrease in yield caused by weeds generated in crop fields, herbicidal active substances that can effectively control them and are safe for crops have been developed. A number of herbicides developed to date have been registered for specific crops and are used for weed control. Herbicides for use in controlling weeds occurring in the plantations of these specific crops have high herbicidal activity and have a broad herbicidal spectrum, but are preferably safe for the environment and crops. However, not all herbicides perfectly meet these conditions.

기존 제초제의 제초 활성 증대와 제초 스펙트럼을 넓히기 위한 방법으로 가장 많이 이용하는 방법은 서로 다른 제초 활성을 가지는 두 가지 이상의 제초 활성 물질을 혼합하는 방법이다. 이와 같이 두 가지 이상의 제초 활성 물질을 혼합하는 경우에 제초제를 개별적으로 잡초에 처리(단제 처리)할 때보다 더욱 우수한 제초 효과를 나타내는 경우가 있다. 이와 같이 구성 성분의 개별 효능에 관한 결과에 따라 예상할 수 있는 효능 또는 활성 수준 이상을 나타내는 경우를 "상승작용"이라고 한다. 하지만 두 개 이상의 제초 활성 물질의 혼합시 제초제의 상승작용이 나타나는 경우는 일부이며, 오히려 두 제초제의 상이한 제초 특성, 흡수, 이행, 또는 대사 등의 차이로 인하여 단제 처리시보다 제초 활성이 낮게 나타나는 경우가 많다. 이와 같이 두 제초 활성 물질의 혼합시 제초 효과가 단제 처리시 보다 낮아지는 경우를 "길항작용"이라고 한다. 또한 제초 활성 물질의 혼합시 제초 효과가 단제 처리시와 변화가 없는 경우를 "상가작용"이라고 한다.The method most commonly used as a method for increasing the herbicidal activity of existing herbicides and broadening the herbicidal spectrum is a method of mixing two or more herbicidal active substances having different herbicidal activities. In this way, when two or more herbicidal active substances are mixed, a better herbicidal effect may be shown than when the herbicides are individually treated on weeds (single agent treatment). In this way, the case of showing more than the expected efficacy or activity level according to the results of the individual efficacy of the constituent components is called "synergy". However, in some cases, when two or more herbicidal active substances are mixed, the synergistic effect of the herbicides appears, and rather, when the herbicidal activity is lower than when treated with a single agent due to the difference in herbicidal properties, absorption, transfer, or metabolism of the two herbicides There are many. In this way, when the herbicidal effect is lowered when the two herbicidal active substances are mixed than when treated with a single agent, it is called "antagonism". In addition, when the herbicidal effect is not changed when the herbicidal active substance is mixed, it is called "additive action".

피리벤족심(Pyribenzoxim, PBX)은 발아에서 완숙되기 전까지(postemergence)의 제초제로서 Acetolactate synthase(ALS) 활성을 억제하는 작용을 가진다. 토양 흡착성이 강하여 주로 경엽 처리용으로 사용된다. 종래에는 피리벤족심(Pyribenzoxim, PBX) 단제 위주로 개발되었으나, 최근 저항성 잡초 출현 및 제초 스펙트럼 확대를 위해 다른 제초 활성 물질과의 합제 개발 연구가 진행되고 있다. 한편, 피리벤족심(Pyribenzoxim, PBX)은 다양한 제형(WP, WG, OD, SC 등)에 대한 연구가 진행되었으나, 다량의 특정 유화제를 포함하는 유제(Emulsifiable Concentrate, EC) 제형에서 가장 우수한 약효를 보였다. 그러나, PBX의 경우 충분한 약효 발현을 위해서 유화제의 함량이 많이 필요하다 보니 용매의 사용량이 제한되었으며, 이로 인해서 합제 개발시 일반적으로 사용되는 용제 나프타(solvent naphtha) 계열의 유기 용매로서는 제형 안정성을 확보하기 어려운 문제가 있었다.Pyribenzoxim (PBX) is a postemergence herbicide that inhibits the activity of acetolactate synthase (ALS). It is mainly used for foliar treatment due to its strong soil absorption. Conventionally, pyribenzoxim (Pyribenzoxim, PBX) was developed mainly as a single agent, but recently, research on the development of a combination with other herbicidal active substances is being conducted to develop resistant weeds and expand the herbicidal spectrum. On the other hand, pyribenzoxim (PBX) has been studied for various formulations (WP, WG, OD, SC, etc.), but the best efficacy was obtained in an emulsifiable concentrate (EC) formulation containing a large amount of a specific emulsifier. seemed However, in the case of PBX, since a large amount of emulsifier is required for sufficient drug efficacy, the amount of solvent used is limited. As a result, it is difficult to secure formulation stability as a solvent naphtha-based organic solvent commonly used in the development of a mixture. I had a difficult problem.

이에, 피리벤족심(Pyribenzoxim, PBX) 합제로서, 피리벤족심(Pyribenzoxim, PBX)과 상승작용으로 우수한 제초 활성을 보이며, 유제(EC) 제형의 제형 안정성이 우수한 제초제 조성물의 개발이 요구된다. Therefore, as a pyribenzoxim (PBX) combination, it is required to develop a herbicide composition that exhibits excellent herbicidal activity through synergistic action with pyribenzoxim (PBX) and has excellent formulation stability of an emulsion (EC) formulation.

Hereinafter, the present invention will be described in more detail to aid understanding of the present invention. At this time, the terms or words used in this specification and claims should not be construed as being limited to ordinary or dictionary meanings, and the inventor appropriately defines the concept of terms in order to explain his/her invention in the best way. It should be interpreted as meaning and concept consistent with the technical idea of the present invention based on the principle that it can be done.

본 발명은 피리벤족심(Pyribenzoxim, PBX), 페녹슐람(Penoxsulam, PNS), 유기 용매 및 유화제를 포함하며, 상기 유기 용매는 감마-부티로락톤(gamma-Butyrolactone, GBL)인 제초제 조성물을 제공한다. The present invention provides a herbicidal composition comprising Pyribenzoxim (PBX), Penoxsulam (PNS), an organic solvent and an emulsifier, wherein the organic solvent is gamma-Butyrolactone (GBL) .

상기 피리벤족심(Pyribenzoxim, PBX)은 발아에서 완숙되기 전까지(postemergence)의 제초제로서 Acetolactate synthase(ALS) 활성을 억제하는 작용을 가진다. 상기 피리벤족심(Pyribenzoxim, PBX)은 토양 흡착성이 강하여 주로 경엽 처리용으로 사용된다. 종래에는 피리벤족심(Pyribenzoxim, PBX) 단제 위주로 개발되었으나, 최근 저항성 잡초 출현 및 제초 스펙트럼의 한계로 다른 제초 활성 물질과의 합제 개발이 필요하였다. 이에, 본 발명에서는 상기 피리벤족심(Pyribenzoxim, PBX)과 페녹슐람(Penoxsulam, PNS)의 합제를 개발하였다. 상기 페녹슐람(Penoxsulam, PNS)은 잎, 뿌리를 통해서 흡수가 가능하고, 잡초의 발아에서 완숙되기 전까지(postemergence)와 잡초 발아 전(preemergence)에 모두 사용할 수 있다. 또한, 상기 페녹슐람(Penoxsulam, PNS)은 화본과 식물, 광엽 잡초, 사초과 식물 등 방제 스펙트럼이 넓다. 상기 피리벤족심(Pyribenzoxim, PBX)과 페녹슐람(Penoxsulam, PNS)의 합제는 속효성 및 약효 지속성이 우수하고, 방제 스펙트럼이 넓으며, 우수한 제초 활성을 보일 수 있다. The pyribenzoxim (Pyribenzoxim, PBX) is a herbicide from germination to postemergence and has an action of inhibiting the activity of acetolactate synthase (ALS). The pyribenzoxim (Pyribenzoxim, PBX) is mainly used for foliar treatment because of its strong adsorption to soil. Conventionally, Pyribenzoxim (PBX) was developed mainly as a single agent, but recently, due to the emergence of resistant weeds and limitations in the herbicidal spectrum, it was necessary to develop a combination with other herbicidal active substances. Accordingly, in the present invention, a combination of Pyribenzoxim (PBX) and Penoxsulam (PNS) was developed. The penoxsulam (PNS) can be absorbed through leaves and roots, and can be used both from weed germination to full maturity (postemergence) and before weed germination (preemergence). In addition, the penoxsulam (PNS) has a wide control spectrum such as flowering plants, broad-leaved weeds, and cyperaceae plants. The mixture of Pyribenzoxim (PBX) and Penoxsulam (PNS) has excellent fast-acting and sustained drug efficacy, has a wide control spectrum, and can exhibit excellent herbicidal activity.

한편, 상기 피리벤족심(Pyribenzoxim, PBX)과 페녹슐람(Penoxsulam, PNS) 합제의 다양한 제형(WP, WG, OD, SC 등)에 대한 연구가 진행되었으나, 다량의 특정 유화제를 포함하는 유제(Emulsifiable Concentrate, EC) 제형에서 가장 우수한 약효를 보였다. 그러나, 유제(EC)의 경우 유화제의 함량이 많이 필요하다 보니 용매의 사용량이 제한되었으며, 유제(EC) 제형에 있어서 일반적으로 사용되는 나프타(naphtha) 계열 또는 아로마틱(aromatic) 계열의 유기 용매의 경우 제형 안정성을 확보하기 어려운 문제가 있었다. 또한, 상기 피리벤족심(Pyribenzoxim, PBX)과 페녹슐람(Penoxsulam, PNS)은 모두 종래 유기 용매에 대한 용해도가 높지 않아 유제(EC) 제형 개발에 어려움이 있었다. 이에, 본 발명에서는 유기 용매로서 감마-부티로락톤(gamma-Butyrolactone, GBL)를 사용함으로써, 용해도를 높이고, 제형 안정성이 우수한 유제(EC) 제형의 피리벤족심(Pyribenzoxim, PBX)과 페녹슐람(Penoxsulam, PNS) 합제 제초제 조성물을 개발하였다.Meanwhile, studies on various formulations (WP, WG, OD, SC, etc.) of the mixture of Pyribenzoxim (PBX) and Penoxsulam (PNS) have been conducted, but emulsions (emulsifiable Concentrate, EC) formulation showed the best efficacy. However, in the case of an emulsion (EC), the amount of solvent used was limited because a large amount of emulsifier was required, and in the case of naphtha-based or aromatic-based organic solvents commonly used in emulsion (EC) formulation There was a problem that it was difficult to secure formulation stability. In addition, both pyribenzoxim (PBX) and penoxsulam (PNS) do not have high solubility in conventional organic solvents, so it was difficult to develop an emulsion (EC) formulation. Therefore, in the present invention, by using gamma-butyrolactone (GBL) as an organic solvent, pyribenzoxim (PBX) and phenoxulam (EC) formulation with improved solubility and excellent formulation stability Penoxsulam, PNS) combined herbicide composition was developed.
