Abstract
Description
기존제형은 보통 3kg/10a 의 처리량을 갖는다. 이를 500g/10a로 줄인 제형으로 처리할 경우 약제무게에 따른 부하를 줄일 뿐만 아니라 처리량이 적어짐에 따라 살포시간이 단축이 되어 획기적인 노동력 절감의 효과를 나타낼 수 있다. 기 특허 출원된 제형은 입제의 크기는 동일하고 수용성필름에 포장을 하여 투척처리하는 제형이 대부분이며, 일본국에서 출원된 특허는 입자의 크기를 3mm이상 85%로 명시하고 있으나 5mm이상일 경우의 입자에 대한 효과가 명확하다 할 수 없다. Existing formulations usually have a throughput of 3 kg / 10a. When processed to a formulation reduced to 500g / 10a, not only reduces the load according to the weight of the drug, but also decreases the spraying time as the throughput is reduced, it can exhibit a significant labor savings effect. Most of the formulations applied for patent application have the same size of granule and most of them are packaged in water-soluble film and thrown out. Patents applied in Japan specify the particle size as 3% or more and 85%, but the particle size is 5mm or more. The effect on can not be clear.
따라서 본 발명은, 농약입제의 단일입자의 직경을 7mm 이상의 대형입자로 제조하여 논둑에서 먼 거리 투척이 가능하며, 무논에 직접 들어가지 않고 처리할 수 있는 면적이 넓어졌으며, 입제의 자체 확산 및 빠른 붕괴로 바람에 의한 영향을 거의 받지 않는 농약입제에 관한 것이다. Therefore, the present invention, the diameter of the single particles of the pesticide granules made of large particles of 7mm or more can be thrown at a long distance from the rice field, the area that can be processed without entering directly into Munnon, the granules self-diffusion and rapid It is about pesticide formulations that are hardly affected by wind from collapse.
기존에 무논 등의 수면에 사용하는 농약의 제제는 입제, 분제, 유제, 수화제, 액상수화제 등이 주로 사용이 되었다. 입제나 분제는 통상 300평에 3kg의 제품을 물에 희석하지 않고 살포하는 방식이고, 유제는 물에 희석하여 살포를 하고, 액상수화제는 500ml의 액을 직접 살포하는 방식으로 사용이 된다. Conventionally, preparations of agrochemicals used for sleep, such as Munon, are mainly used as granules, powders, emulsions, hydrating agents, and liquid hydrating agents. Granules and powders are usually sprayed without diluting 3kg of product in 300 pyeong without diluting with water, emulsions are sprayed with dilution in water, and liquid emulsifiers are used by directly spraying 500 ml of liquid.
위와 같은 제제는 처리면적이 넓을 경우 많은 양의 약제를 직접 들고 살포하여야만 하기 때문에 그 무게에 따른 노동력의 부하가 적지 않았으며, 논둑에서 살포 가능한 액상수화제는 약액이 닿는 거리가 짧아 논폭이 10m 이상일 경우 약제를 처리하기 위해서는 작업자가 반드시 논에 직접 들어가야 하는 어려움이 있다. Since the above formulation has a large treatment area, a large amount of chemicals must be directly applied and sprayed, and the labor load according to its weight is not a small amount. In order to process the drug, there is a difficulty that the worker must enter the paddy field directly.
이런 어려움으로 인해 무논투척용 농약 점보제 및 수면부상성 농약입제 등이 개발되고 있고, 공개특허 제1997-0002003호의 수면부상성 농약입제 및 그의 제조방법, 공개특허 제2000-0076729호의 수면적용용 농약제제, 공개특허 제2001-0085392호의 무논용 농약조성물, 그의 제조방법 및 그의 살포방법, 공개특허 제2001-0099683호의 무논용 농약제제, 그의 제조방법 및 살포방법, 공개특허 제1997-0073337호의 무논 투척처리용 농약 점보제 및 그의 제조방법 등은 모두 0.7mm내외의 스크린을 이용해 조립 후 건조하여 수용성필름에 25g내지 50g단위로 포장한 제형으로 수용성필름포장 작업이 추가되어 별도의 시설 투자가 요구되며, 수용성필름의 사용에 따라 수분관리에 부단한 주의가 필요하다. 또한 수온에 의해 필름의 녹는 시간이 영향을 받아 낮은 온도에서는 필름의 녹는 시간이 증가하고, 필름과 직접 닿은 약제는 붕괴가 늦어 바람에 의해 한곳으로 몰리는 현상이 발생하여 약해발생이 우려된다. 또한 증량제로 사용되는 염화칼륨이 철을 부식시키는 성질이 있어 제조설비를 스테인리스스틸로 전면 교체해야 하는 단점이 있다.Due to this difficulty, munon-jumping pesticide jumbo and sleep-injured pesticide granules are being developed, and sleep-injury pesticide granules of Korean Patent Publication No. 1997-0002003 and its manufacturing method, and sleep application pesticides of Patent Publication No. 2000-0076729 Formulation, Munnon pesticide composition of Unexamined Patent Publication No. 2001-0085392, preparation method thereof and spraying method thereof, Munnon pesticide preparation of Unexamined Patent Publication No. 2001-0099683, preparation method thereof and spraying method, Munnon throwing of Patent No. 1997-0073337 The processing pesticide jumbo and its manufacturing method are all assembled after drying using a screen of about 0.7mm and then packaged in 25g to 50g units in a water-soluble film. Due to the use of water-soluble film, care must be taken in managing moisture. In addition, the melting time of the film is affected by the water temperature, the melting time of the film is increased at low temperatures, the drug directly contacted with the film is decayed late due to the phenomenon of being driven to one place by the wind is a concern that the weakness occurs. In addition, since potassium chloride used as an extender has a property of corrosive iron, there is a disadvantage in that the manufacturing equipment must be replaced with stainless steel.
또한 발포성정제는 통상 수g 혹은 수십g의 정제 형태로 제품중의 성분이 물과 접촉 할 때 격렬하게 발생하는 이산화탄소에 의하여 덩어리상의 농약이 미세한 입자로 환원되는 동시에 먼 거리까지 농약이 퍼져나갈 수 있게 고안된 제형이다. 이러한 제형은 처리지점에 농약이 고농도로 잔류하는 현상을 극복하기 어려우며 투척한 제품이 논토양에 파묻혀 살포된 지점에 약해발생이 일어나기도 하며, 산과 알칼리가 제제 중에 혼재하므로 가수분해 등 화학적으로 분해되기 쉬운 농약에는 적용할 수 없어서 극히 제한적인 수의 농약에 대해서만 제품화가 가능하다. 또한 장기간 보관시 발포력이 저하되는 경우가 많으며, 재료비가 기존 제형에 비하여 매우 고가라는 단점이 있다.In addition, effervescent tablets are usually in the form of tablets of several grams or tens of grams so that the intensive pesticides can be reduced to fine particles by the carbon dioxide generated when the components in the product come into contact with water, and the pesticides can be spread to a long distance. It is a formulated formulation. Such formulations are difficult to overcome the phenomenon of high concentration of pesticides in the processing point, and the products thrown into the paddy soil are weakened at the point where they are sprayed, and because the acid and alkali are mixed in the formulation, they are decomposed chemically. It is not applicable to easy pesticides, so it is possible to commercialize only a very limited number of pesticides. In addition, foaming power is often lowered during long-term storage, and the material cost is very expensive compared to the conventional formulation.
일본국에서 출원한 특허(특개평15-026816호)와 유사하나 출원된 특허의 제형은 입자의 직경을 3~5mm로 제조를 하여 포장실험을 하였고, 비록 7mm 입자 제형은 제제예에 언급이 되었으나 포장실험은 진행하지 않고 실내실험만 진행하였다. 또한 실험결과 7mm 이상의 입자에서는 수면아래로 가라앉는 입자가 발생하여 7mm로 제시한 제형이 완전하다 할 수 없다. 아울러 손으로 투척시 살포거리가 3~6m로 논폭이 20m 이내일 경우에만 논둑 살포가 가능하여 수도 원액처리용 액상수화제처럼 처리면적이 한정적인 단점을 가지고 있다. 또한 증량제로 철을 부식시키는 성질이 있는 염화칼륨을 사용하여 스테인리스스틸로 설비되지 않은 시설에서는 기존 처방으로 입제를 제조시 염에 의한 부식현상이 발생하여 기존설비를 바꿔야 하는 단점을 갖고 있다.Similar to the patent filed in Japanese Patent Application (Japanese Patent Application Laid-Open No. H15-026816), but the formulation of the applied patent was prepared by packaging the particles with a diameter of 3 to 5 mm, although the 7 mm particle formulation was mentioned in the formulation example. Only the indoor experiment was conducted without the pavement experiment. In addition, as a result of the experiment, the particles settled below the surface of the particles of 7mm or more occurred, and the formulation of 7mm could not be completed. In addition, when throwing by hand, the spraying distance is 3 ~ 6m, and the rice paddy can be sprayed only when the rice padding width is within 20m. In addition, facilities that are not equipped with stainless steel using potassium chloride, which has the property of corroding iron as an extender, have the disadvantage of having to change existing equipment due to corrosion phenomenon caused by salt when manufacturing granules by conventional prescription.
본 발명은 상기와 같이 종래 제공되던 농약제제의 문제점을 개선하고자 하는 것으로 철을 부식시키는 염화칼륨을 증량제로 사용하지 않고, 수용성필름포장에 따른 제조설비의 교체나 추가의 부담이 적고 사용자의 입장에서 살포거리를 증가시켜 좀더 개선된 생력화 제형으로 만들고자 하는 것이다.The present invention is to improve the problems of the conventional pesticides provided as described above, without using potassium chloride to corrode iron as an extender, there is little replacement or additional burden of manufacturing equipment according to water-soluble film packaging and spraying from the user's point of view Increasing the distance would result in a more improved viability formulation.
따라서 본 발명자는 상기한 제제의 단점을 개선할 수 있는 제형을 만들고자 연구를 한 결과, 수용성의 증량제를 사용하여 염화칼륨을 대치할 수 있었고, 단일입자의 직경을 7mm이상으로 제조하여 낱알살포가 가능하였으며 손 살포시 입자의 비산거리가 10m 이상으로 증가한다는 것을 알 수 있었다. Therefore, the present inventors conducted a study to make a formulation that can improve the disadvantages of the above formulations, it was possible to replace the potassium chloride by using a water-soluble extender, it was possible to produce a single particle diameter of more than 7mm It was found that the scattering distance of the particles increased by more than 10m when hand spraying.

논폭이 가로×세로 40×100m이고, 평균수심 5cm인 무논에 실시예1, 실시예2와 비교예2 약제를 논둑에서 손으로 살포하여 약제의 비산거리를 측정하였고, 전체면적을 처리하기 위해 논에 들어가는 횟수와 약제처리에 걸린 총 시간을 측정하였다. Example 1, Example 2 and Comparative Example 2 were sprayed by hand from the rice paddy field to Munnon, which has a width of 40 × 100 m and an average depth of 5 cm, to measure the scattering distance of the medicine, and to treat the whole area. The number of times entered and the total time taken for drug treatment were measured.
[표 2] 살포비산거리 시험 결과[Table 2] Spray scattering distance test results
비교예2의 경우 5m간격으로 총 7번 논에 들어갔고, 약제처리에 걸린시간은 50분이었다.In the case of Comparative Example 2, a total of seven rice paddies were entered at intervals of 5 m, and the time required for chemical treatment was 50 minutes.
실시예2 입제는 10m간격으로 총 3번을 들어갔으며 총 30분의 시간이 소요됐으며, 실시예1 입제는 20m지점에서만 논에 들어가서 처리를 하여 총 15분의 시간이 소요되었다. Example 2 The granules were entered three times at 10m intervals and took a total of 30 minutes. Example 1 granules were entered into a rice field only at a 20m point and processed for a total of 15 minutes.
따라서 실시예1로 제조하여 입자의 크기를 7mm로 한 결과 약제처리에 소용되는 시간이 비교예2 대비 70% 절약되었고, 실시예2 대비 50%의 시간절약 효과가 있음을 알 수 있었다.. Therefore, when the size of the particles prepared in Example 1 to 7mm, the time used for drug treatment was 70% less than that of Comparative Example 2, and it was found that there was a 50% time saving effect compared to Example 2.
약효 및 약해 시험Drug efficacy test
확산성 및 살포거리 측정시험에 사용된 처리구에서 잡초 초종별 약효실험을 수행하였다. Weed efficacy experiments were performed in the treatments used for the diffusion and spreading distance measurement tests.
약제살포 후 제초효과는 100%(완전고사)부터 0%(효과없음)로 구분하여 표시하였고 벼에 대한 약해는 0(약해없음)부터 9(완전고사)로 표시하였다.After spraying the drug, herbicide effect was divided into 100% (completely tested) and 0% (no effective), and the damage to rice was expressed from 0 (no bad) to 9 (completely tested).
[표 3] 초종별 약효 및 약해 시험결과[Table 3] Drug efficacy and test results of different species
상기 결과와 같이 일반제형에 비해 노동력시간이 70% 이상 절감이 되었고 약효 또한 우수하게 나타나 제형의 실용화에 문제가 없는 것으로 나타났다. As shown in the above results, the labor time was reduced by more than 70% compared to the general formulation, and the drug efficacy was also excellent, indicating that there was no problem in the practical use of the formulation.
본 발명은 입제의 크기에 따라 살포거리가 달라질 수 있음을 인지하여 입제의 직경을 7mm이상으로 제조하여 단일입자의 무게를 증가시켰다. 그로 인해 입자의 살포거리가 10m이상으로 증가하여 논에 직접 들어가지 않고 논둑에서 살포 가능한 논폭의 범위가 40m로 증가하여 약제살포시간을 단축시키는 효과를 가져올 수 있었다. The present invention was recognized that the spraying distance may vary depending on the size of the granules to increase the weight of the single particles by producing a diameter of the granules 7mm or more. As a result, the spraying distance of the particles was increased to 10m or more, so that the range of rice padding that could be sprayed from the rice paddy was increased to 40m without directly entering the paddy field, thereby reducing the drug spraying time.
또한 확산성 및 빠른 붕괴성을 부여하여 낙하지점으로부터 10m지점에도 농약활성성분이 검출되어 고른 살포효과를 가져오는 것을 알 수 있었고, 실제 논포장 실험에서 효과 또한 우수한 효과가 있었다.In addition, it was found that the active ingredient was detected even at 10m from the dropping point by providing diffusibility and rapid disintegration, resulting in an even spraying effect.
또한 수용성담체로 부식성이 없는 요소를 사용하여 시설을 부식시키는 부작용이 없으며, 기존설비 그대로 사용이 가능하여 설비변형에 따른 경비 지출이 없으며, 수용성필름의 포장단계가 필요치 않아 매우 경제적인 효과가 있다. In addition, there is no side effect to corrode the facility by using the non-corrosive element as a water-soluble carrier, and can be used as it is, there is no expense due to the deformation of the facility, there is no need for the packaging step of the water-soluble film, there is a very economic effect.
