Description
본 발명은 벼 해충 동시방제제 및 이를 이용한 벼 해충 방제방법에 관한 것으로, 보다 상세하게는 벼물바구미, 벼잎굴파리, 벼줄기굴파리, 벼애잎굴파리에 대한 동시 방제효과가 매우 우수하면서도 독성이 낮고 인축에 안전하여 친환경 벼를 재배하는 농가에서 고품질 벼를 생산하는데 기여할 뿐만 아니라 해충 방제 노동력을 크게 절감할 수 있는 벼 해충 동시방제제 및 이를 이용한 벼 해충 방제방법에 관한 것이다.
The present invention relates to a simultaneous control of rice pests and a method for controlling rice pests using the same, and more particularly, the simultaneous control effect against rice weevil, rice leaf oyster flies, rice stem oyster flies, rice leaf oyster flies, very low toxicity, The present invention relates to a rice pest control method and a method for controlling rice pests using the same, which not only contribute to producing high quality rice in farms growing safe and environment-friendly rice, but also greatly reduce the pest control labor force.
벼를 재배하는 경우 초기 해충으로는 벼물바구미와 굴파리류가 있다. 벼물바구미는 년 1회 발생하는데, 월동한 후 4월 중하순경에 지상부로 나와 활동을 시작하며 화본과 잡초를 먹고 비상근을 발달시킨 후 5월 중하순 경부터 보행 혹은 비상에 의하여 논으로 이동한다. 대부분의 월동성충은 5월 하순에 논으로 이동하기 때문에 이 무렵에 성충 밀도가 가장 높고 6월 중순 부터는 급격히 감소한다. 성충의 식흔(食痕)은 엽맥을 따라서 폭 1 ㎜가량 길쭉한 직사각형 모양으로 나타내고, 유충은 뿌리를 갉아먹기 때문에 분열이 억제되고 줄기수가 감소하며, 피해가 심할 때에는 생육이 정지되고 쉽게 뽑히게 된다. 일반적으로 담수직파에서는 이앙재배에 비하여 피해가 크게 나타난다. In the case of growing rice, early pests include rice weevil and oysters. Rice weevils occur once a year. After wintering, they come out to the ground in mid and mid April and begin their activities. Most wintering adults migrate to paddy fields in late May, with the highest adult density at this time of year and decreasing rapidly from mid-June. Adult food streaks (痕) along the leaf vein in the shape of an elongated rectangular shape of about 1 mm in length, the larvae eat the roots, so that the division is suppressed, the number of stems is reduced, and when the damage is severe, the growth is stopped and easily pulled out. In general, freshwater waves suffer more damage than rice transplanting.
벼줄기굴파리는 1년에 3회 발생하며 본논 초기에 알에서 나온 애벌레가 잎속으로 들어가 새로운 잎을 가해하면 잎이 나왔을 때 잎에 세로로 가늘고 긴 구멍들이 생긴다. Rice stalk flies occur three times a year, and when larvae from eggs enter into the leaves at the beginning of the main rice paddy and add new leaves, the leaves become thin and long holes in the leaves.
이러한 초기 해충을 방제하기 위해서 기존의 합성 농약의 입제를 사용하였으나 2006년부터 친환경농업육성법이 발효됨에 따라 무농약과 유기농산물 인증 논에서는 유기농자재만을 사용하여 해충을 방제하여야 한다.In order to control these early pests, the existing granulated pesticides were used. However, since the Environmental Agriculture Promotion Act came into effect from 2006, only pesticides and organic product certified rice paddies should be used to control pests.
농약은 농업생산성 증가와 해충으로부터 인간을 보호하는데 커다란 공헌을 해왔고 사용량도 꾸준히 증가하여 왔다. 현재 살충제와 제초제 등의 농약은 유기염소계. 유기인산계, 카바메이트계 등이 주종을 이루며, 이들 모두 심각한 독성과 낮은 분해성으로 인하여 생태계에서 먹이 사슬에 의하여 축적되게 된다. 이러한 화학합성농약이 지니고 있는 단점은 약제를 살포하는 회수의 증가와 살포농도의 증가로 인한 저항성 해충의 출현으로 해충방제 효과는 점점 감소하는 반면에 천적들은 치명적인 타격을 받아 잠재적 곤충의 해충화에 따른 새로운 해충의 출현이 많아지고 있다는 것이다. 또한 농산물의 잔류 농약량의 증가로 농산물의 독성이 증가되어 식품에 대한 부정적인 요인으로 작용하고 있다.Pesticides have made significant contributions to increasing agricultural productivity and protecting humans from pests, and their use has steadily increased. Currently, pesticides such as insecticides and herbicides are organochlorine. Organophosphates and carbamates are the predominant species, all of which are accumulated by the food chain in the ecosystem due to severe toxicity and low degradability. The disadvantage of these chemical synthetic pesticides is that the pest control effect gradually decreases due to the increase in the number of spraying drugs and the emergence of resistant pests due to the increase of the spraying concentration. The emergence of new pests is increasing. In addition, the toxicity of agricultural products is increased due to the increase in the amount of pesticide residues, which is a negative factor for food.
합성 농약의 한계를 극복하기 위한 차세대 농약의 개발 일환으로 생물학적 방제가 활발히 연구되고 있다. 생물학적 방제는 미생물, 천적 또는 천연추출물을 이용하는데 미생물과 천연물 제제는 취급하기가 용이하지 않아 상업화의 장애가 되고 있다. 따라서 사람과 동식물에 무해하고 환경 친화적이며 취급이 용이하고 생산 가격이 낮은 천연물 농약의 개발이 절실히 요구되고 있다. 국내의 천연 바이오메스 중에서는 살충효과가 있는 물질이 많음에도 불구하고 이에 대한 농약으로서의 개발은 전무한 실정이다. 따라서 국내에서 자생하는 생리활성 물질이 있는 유용한 식물자원을 이용하여 생태 친화적인 새로운 살충제의 개발이 매우 긴급한 실정이다.
As part of the development of next-generation pesticides to overcome the limitations of synthetic pesticides, biological control is being actively researched. Biological control uses microorganisms, natural enemies or natural extracts, and microorganisms and natural product preparations are not easy to handle, which is an obstacle to commercialization. Therefore, there is an urgent need for the development of natural product pesticides that are harmless to humans and animals, environmentally friendly, easy to handle, and low in production. Although there are many substances with insecticidal effects among natural biomass in Korea, there is no development as a pesticide. Therefore, it is very urgent to develop new eco-friendly insecticides using useful plant resources with native bioactive substances.

Hereinafter, the present invention will be described in more detail with reference to examples. However, the following illustrated examples are only presented to aid the understanding of the present invention and should not be construed as limiting the scope of the present invention.
[실시예 1]Example 1
벼물바구미 방제제로서 멀구슬나무 열매 500g을 마쇄하여 가루로 만들고 식물건조 중량의 3배에 달하는 에탄올을 가해 3일간 암실에 보관하였다. 여과 과정을 통해 추출물을 얻고, 40~45℃에서 감압농축하여 얻어진 액을 농도별로 제올라이트에 분사처리하여 입제화시켰다. 코팅을 위해 고령토를 5 중량% 비율로 첨가하였다. 이와 같이 고령토를 코팅함으로써 제올라이트에 묻어 있는 멀구슬 살충 성분이 서서히 분출되어 나올 수 있으며, 장기보관시에도 코팅에 의해 멀구슬 살충 성분의 유실을 방지할 수 있다. 실험에 사용된 제올라이트의 크기는 1.5~2ml 정도로 분쇄된 것으로서 전체 용량은 85 중량%, 고령토는 5 중량%, 멀구슬추출액은 10 중량%를 기본으로 하여, 멀구슬 농도가 낮아진 만큼 제오라이트의 용량을 늘려 총 100%로 맞추었다.
As a rice weevil control, 500 g of mulberry fruit was ground and pulverized, and ethanol, which was three times the weight of plant drying, was added and stored in a dark room for 3 days. The extract was obtained through a filtration process, and the liquid obtained by concentration under reduced pressure at 40 to 45 ° C. was granulated by spraying on zeolite for each concentration. Kaolin was added at a rate of 5% by weight for coating. By coating the kaolin as described above, the mulberry insecticide component buried in the zeolite may be slowly ejected, and even when stored for a long time, it is possible to prevent the loss of mulberry insecticide component by the coating. The size of the zeolite used in the experiment was 1.5 ~ 2ml, and the total volume was 85% by weight, kaolin was 5% by weight, and mulberry bead extract was based on 10% by weight. Increased to 100%.
벼의 생육 초기 주요 해충인 벼물바구미와 굴파리류를 방제하기 위해 입제로 제형화하여 정식하루 전에 유묘상자 당 20g, 40g, 80g씩 살포하고 10일째에 피해엽율을 30주씩 3반복으로 조사하였다.To control rice weevil and oyster flies, the main pests in the early stage of rice growth, they were formulated into granules and sprayed 20g, 40g, 80g per seedling box before the day of planting, and the damage leaf rate was repeated three times for 30 weeks at 10 days.
조사결과 멀구슬 10% 농도 80g을 벼 육묘상자에 살포한 경우 피해엽율이 2.2%로 가장 낮았으며 10% 40g과 7% 80g 처리에서도 피해엽율이 4.6~4.7%로 낮게 나타났다. As a result, when 80g of mulberry ball 10% concentration was sprayed on the rice seedling box, the damage rate was the lowest at 2.2%, and the damage rate was low at 4.6 ~ 4.7% even at 10% 40g and 7% 80g treatment.
벼굴파리인 벼줄기굴파리, 벼잎굴파리, 벼애잎굴파리등에 대한 피해엽율은 멀구슬 10% 80g에서 1.3%였으며 40g에서도 2.7%로 낮았다. The damage rate of rice flies such as rice oyster flies, rice leaf oyster flies, and rice leaf oyster flies was 1.3% in mulberry bulbs at 80% and 2.7% in 40g.
상기와 같이 본 발명에 따른 벼 해충 동시방제제를 벼 모판에 적용한 결과 벼물바구미 뿐만 아니라 벼굴파리류에 대한 방제활성도 매우 우수함을 확인할 수 있어 본 발명에 따른 방제제는 식물 추출물을 사용하여 독성이 낮고 인축에 안전하여 친환경 벼를 재배하는 농가에서 고품질 벼를 생산하는데 기여할 뿐만 아니라 해충 방제 노동력을 크게 절감할 수 있음을 확인할 수 있다. As a result of applying the rice pest simultaneous control agent according to the present invention as described above to the rice bed plate, it can be confirmed that not only the rice weevil, but also the control activity against the rice flies, the control agent according to the present invention is low toxicity using a plant extract It can be seen that not only does it contribute to producing high-quality rice in farms that are safe for human farming, but also saves on pest control labor.
