Description

살초용 조성물Herbicide Composition

위 일반식에서In the above general formula

X는 펜아실기 또는 4-메틸펜아실기를 나타낸다.X represents a penacyl group or 4-methylphenacyl group.

현재, 수전용 제초제로서 수많은 제초제가 실용화되고 있으며 단제 및 혼합제로서 널리 일반적으로 사용되고 있다. 그러나, 수전잡초는 다종류에 이르며 1년생 잡초에 유효한 제초제는 수많지만 다년생 잡초에 효과가 있는 제초제는 거의 없다. 그로 인하여 다년생 잡초가 증가하고, 따라서 그 방제가 절실히 요망되고 있다.At present, a number of herbicides have been put into practical use as power herbicides and are widely used as a single agent and a mixed agent. However, hydrangea weeds come in many varieties and are effective herbicides for annual weeds, but few herbicides are effective for perennial weeds. As a result, perennial weeds are increasing, and therefore control is urgently desired.

다년생 잡초는 일반적으로 성장이 왕성하며 발생기간이 길어서 강한 해초의 일종이기도 하다. 따라서 제초제로서는 많은 종류의 잡초를 고살시킬 수 있는 살초스펙틀의 넓은 성질의 것이 요망된다.Perennial weeds are generally a strong type of seaweed because of their high growth and long development period. Therefore, as a herbicide, the thing of the broad nature of the herbicide spectle which can kill many kinds of weeds is desired.

또, 최근의 수도재배는 기계화의 도입, 이식시기의 조기화가 급속히 퍼져서 종래 이상으로 잡초발생에 알맞는 장소를 주고 있으며 1회의 제초제시용으로서는 완전한 잡초방제를 기대할 수 없는 경향에 있다. 이로 인하여 동일 혹은 상이되는 제초제가 몇회에 걸쳐서 반복사용되고 있는데 이와 같은 제초제의 반복사용은 크고 많은 노력을 요할 뿐만 아니라 다량시용에 따른 수도약해나 토양잔류 등 바람직하지 않은 문제를 제기하고 있다.In addition, in recent years, since the introduction of mechanization and the early transplantation period have spread rapidly, they have given a place suitable for weed generation more than the conventional one, and there is a tendency that complete weed control cannot be expected for one herbicide application. As a result, the same or different herbicides are repeatedly used several times. The repeated use of such herbicides is not only large and requires a lot of effort, but also poses undesirable problems such as water weakness or soil residues caused by large amounts of application.

본 발명자들은 종래의 제초제에 있어서 이들 문제점을 개량하는 목적으로서 1회 살포로서 모든 잡초는 완전히 방제하고 더욱이 수도에 대해서 고도의 안전성을 가지며, 인축독성이 매우 낮은 안전한 제초제의 검색을 계속한 결과 2종의 유효성분을 배합하므로서 이들의 문제점을 개량한 뛰어난 제초제가 얻어진다는 것을 알고 본 발명을 완성하였다.As a result of the improvement of these problems in the conventional herbicides, the inventors of the present invention, as a single spray, completely control all the weeds and further have a high safety against water, and continue to search for safe herbicides with very low human toxicity. The present invention was completed by knowing that an excellent herbicide having improved these problems can be obtained by blending an active ingredient.

즉, 본 발명은 수전용 제초제로서 공지의S-(4-클로로벤질) N,N-디에틸티올카아바메이트(가) 또는 S-에틸-헥사히드로(1H) 아제핀-1-카르보티오에이트(나) 및 일반식(Ⅰ)의 피라졸계 화합물과의 혼합제이다.That is, the present invention is a known herbicide for S- (4-chlorobenzyl) N, N-diethylthiol carbamate (valent) or S-ethyl-hexahydro (1H) azepine-1-carbothio It is a mixing agent with the pyrazole type compound of the compound (I) and general formula (I).

본 발명을 더 상세히 설명하면 본 제초조성물의 성분의 하나인 (가) 및 (나)는 들피에 대하여 효과가 높고 또한 벼와 피와의 선택성이 대단히 크며 벼에 대하여 안전성이 높다. 또 최근 문제로 되어 있는 다년생 잡초인 너도방동산이, 올챙이 고랭이 등에 대하여서도 생육초기처리로서 활성이 있지만 생육이 진행되면 효과가 약해진다.When explaining the present invention in more detail, (a) and (b), one of the components of the herbicidal composition has a high effect on the grass, the selectivity between the rice and the blood is very high and the rice is safe. In addition, the perennial weed, which is a perennial weed, is also active as an initial growth treatment for tadpoles and mussels, but when the growth progresses, the effect is weakened.

한편, 피라졸계 화합물(다)는 수도에 있어서는 수전에 약해를 미치는 일이 없고 1년생 벼과잡초, 광엽잡초 및 너도방동산이, 벗풀 등의 다년생 잡초에 대해서도 효과를 갖는다. 그러나 잡초가 어느정도 커졌을 시기에 약제처리하면 그 효과는 저하하고 특히 들피에 대한 효과는 불충분하게 된다.On the other hand, the pyrazole-based compound (C) does not cause weakening of the faucets in water, and is effective also on perennial weeds such as annual weed, broadleaf weed and beetroot, and peeled grass. However, when the weeds grow to some extent, the treatment is reduced, and the effect on the grass in particular is insufficient.

그러나 양자를 혼합시용하여 그 제초효과, 약해 등에 관하여 검토한 결과 놀랄만한 것에 각 단제로서 얻어지고 있던 적용범위를 넘어서 살초폭이 확대되며, 그 살초폭은 벼과, 금방동산이과, 일반광엽잡초 및 올챙이고랭이, 너도방동산이, 올미 등의 다년생잡초 일반에까지 미치고 더 나아가서는 수도에 대한 안전성을 손상함이 없이 그 살포적 기폭을 확대시킬 수 있다고 하는 효과가 판명되었다.However, the mixed application of both of them examined herbicidal effects, weaknesses, etc., and surprisingly, the breadth of bread was widened beyond the range of application as a single herb, and the breadth of bread was the rice, Geumbangsan family, general broadleaf weed and tadpole. It has been found that algae, beetles, and even perennial weeds, such as snares, can extend their spraying decay without compromising the safety of the water supply.

또 본 제초제는 단미사용약량보다 훨씬 저약량 끼리의 혼합으로서 충분히 그 효과를 발휘하며 1회 처리제로서 충분할만큼 살초효력의 증대가 꾀해지며, 그 효력지속성은 장기간에 미친다.In addition, the herbicide is sufficiently mixed as a low dosage than a single unused dose, and the effect is sufficiently increased as a single treatment agent, and the herbicidal effect is sufficiently increased, and its effect lasts for a long time.

본 발명의 제초제의 한쪽의 유효성분인 전기한(Ⅰ)식의 화합물(다)는 예를들면 다음의 반응식으로 나타낸 것처럼 화합물(Ⅱ)을 기 X에 대응하는 치환알킬화제로서 치환알킬화하므로서 용이하게 제조할 수 있다.Compound (C) of formula (I), which is an active ingredient of one of the herbicides of the present invention, is easily prepared by, for example, replacing alkyl (II) with a substituted alkylating agent corresponding to group X, as shown in the following reaction scheme. can do.

위 표 (2) 중의 수자는 상승효과의 검정법으로서 일반적으로 이용되는 다음 콜비식에 따라 산출한 배합제의 잡초억제치의 예상치(PE)이다.The number in Table (2) above is the expected value (PE) of the weed suppression value of the compounding agent calculated according to the following Colby equation which is generally used as a test for synergy effect.

PE=Pa+Pe(10-Pa)/10 (Pa=제초제 가의 ag에 있어서 억제치)PE = Pa + Pe (10-Pa) / 10 (inhibited value in Pa = herbicide ag)

(Pe=제초제 다의 cg에서의 억제치)(Pe = inhibition of cg of herbicide c)

그 결과 배합제의 억제치의 실측치(Pd)는 예상치(PE)보다 커서, 상승효과가 현저하게 나타남이 입증된다.As a result, the measured value Pd of the inhibitory value of a compounding agent is larger than the expected value PE, and it demonstrates that a synergistic effect is remarkable.
