Description
본 발명은 에틸포메이트에 의한 농업용 재배 작물 약해 저감방법 및 농업용 재배 작물 보호제에 관한 것이다.The present invention relates to a method for reducing damage to agricultural crops by ethyl formate and a protection agent for agricultural crops.
에틸포메이트(Ethyl formate)는 메틸브로마이드(methyl bromide)를 대체하기 위해 사용되고 있으며 저장 곡류, 수출입 농산물(과실, 채소류)대상 훈증제로 사용되어 지고 있다. 에틸포메이트는 자연 유래 물질로 에탄올과 포름산으로 가수분해되는 특징을 가지고 있으며, 잔류가 되지 않는다고 알려져 있다. 검역 과정에서 수입 식물별로 소독기준을 설정하여 소독 처리하고 있으나 훈증 처리 후 약해가 발생한다는 보고가 있다. 현재 국내 농가로 유입된 검역 해충의 발생으로 인한 검역해충의 방제법 개발 및 농업해충의 방제법 개발을 위하여 에틸포메이트의 사용이 검토 되고 있는 시점에서 에틸포메이트의 사용으로 인한 농작물의 약해 발생은 농가에 큰 경제적 손실을 야기할 것으로 보인다. 이러한 우려에도 불구하고 에틸포메이트에 의한 약해기작이 불분명하고, 이에 따른 저감화 방법도 마련되지 못한 실정이다. Ethyl formate is used to replace methyl bromide and is used as a fumigant for stored grains and imported and exported agricultural products (fruits and vegetables). Ethyl formate is a naturally occurring substance that hydrolyzes into ethanol and formic acid, and is known not to remain. During the quarantine process, disinfection standards are set for each imported plant and disinfected, but there are reports that damage occurs after fumigation. Currently, the use of ethyl formate is being reviewed for the development of quarantine pest control methods and agricultural pest control methods due to the occurrence of quarantine pests introduced into domestic farms, and the occurrence of crop damage due to the use of ethyl formate is a concern for farmers. It is expected to cause great economic loss. Despite these concerns, the mechanism of damage caused by ethyl formate is unclear, and a corresponding reduction method has not been established.

<실험예 1> 수박의 약해 저감효과의 확인<Experimental Example 1> Confirmation of the effect of reducing the damage of watermelon
탄산수소나트륨(NaHCO3)를 전처리하여, 에틸포메이트 훈증제로 인해 발생하는 약해의 저감 정도를 확인하였다. 먼저 증류수에 탄산수소나트륨(NaHCO3)을 1 %로 용해한 뒤 수박의 잎 앞면 및 뒷면 모두에 미세분무기를 이용하여 분사해주었다. 대조군의 경우 증류수만을 분무하여 비교하였다. 30분 내지 1시간 이상 풍건하여 수분을 모두 날려주었다. 이후, 에틸포메이트 훈증에 의해 약해 발생하는 농도구간(7.5 g/m3 이상)에 훈증을 2시간 처리하였다. 훈증 처리 후, 약해 저감 효능은 훈증 처리 후 1일 뒤 사진 촬영하여 확인하였으며, 잎의 약해는 7일 후 약해 증상이 육안으로도 가장 많은 차이를 보였다. By pre-treating sodium bicarbonate (NaHCO 3 ), the degree of reduction in damage caused by the ethyl formate fumigant was confirmed. First, 1% sodium bicarbonate (NaHCO 3 ) was dissolved in distilled water and then sprayed on both the front and back of the watermelon leaves using a fine sprayer. In the case of the control group, only distilled water was sprayed and compared. It was air-dried for over 30 minutes to 1 hour to remove all moisture. Afterwards, fumigation was performed for 2 hours in the concentration range (above 7.5 g/m 3 ) that was weakened by ethyl formate fumigation. After fumigation treatment, the effectiveness in reducing damage was confirmed by taking pictures 1 day after fumigation, and the symptoms of leaf damage showed the greatest difference even with the naked eye after 7 days.
도 1은 탄산수소나트륨(NaHCO3) 및 에틸포메이트 농도에 따른 수박의 약해 저감효과를 실험한 결과를 나타낸 사진이다. 도 1을 참고하면, 수박에 에틸포메이트 2시간 훈증 시 약해가 발생하는 농도 구간인 7.5 g/m3와 10 g/m3에 대하여 훈증 전 탄산수소나트륨(NaHCO3)을 0.5 %와 1 % 경엽처리한 뒤, 훈증 처리 후 1일 뒤 수박 잎에서 약해가 저감됨을 확인할 수 있었다. 탄산수소나트륨(NaHCO3)의 단독 처리에 의해서는 수박 잎에 영향을 주지 않았다. 또한, 에틸포메이트를 7.5 g/m3와 10 g/m3농도로 2시간 훈증 처리 시 수박 잎 끝부분부터 까맣게 되는 약해현상을 확인할 수 있으나, 에틸포메이트 7.5 g/m3 처리구에서 탄산수소나트륨(NaHCO3) 0.5 %와 1 % 전처리가 약해를 확연히 감소시킨 것을 확인하였다.Figure 1 is a photograph showing the results of an experiment on the effect of reducing damage to watermelon depending on the concentration of sodium bicarbonate (NaHCO 3 ) and ethyl formate. Referring to Figure 1, when fumigating watermelon with ethyl formate for 2 hours, sodium bicarbonate (NaHCO 3 ) was added at 0.5% and 1% before fumigation for the concentration ranges of 7.5 g/m 3 and 10 g/m 3 where mild damage occurs. After foliage treatment, it was confirmed that damage to watermelon leaves was reduced 1 day after fumigation. Treatment with sodium bicarbonate (NaHCO 3 ) alone had no effect on watermelon leaves. In addition, when fumigating ethyl formate at concentrations of 7.5 g/m 3 and 10 g/m 3 for 2 hours, a weakening phenomenon in which watermelon leaves turn black from the tips can be confirmed, but hydrogen carbonate is removed from the ethyl formate 7.5 g/m 3 treatment group. It was confirmed that pretreatment with 0.5% and 1% sodium (NaHCO 3 ) significantly reduced the toxicity.
<실험예 2> 애호박의 약해 저감효과의 확인<Experimental Example 2> Confirmation of the effect of reducing the damage of zucchini
작물로 수박 대신 애호박을 사용한 것을 제외하고는 상기 실험예 1과 동일한 방법으로 약해 저감효과를 확인하였고, 이를 도 2에 나타내었다.The damage reduction effect was confirmed in the same manner as in Experimental Example 1, except that zucchini was used instead of watermelon as the crop, and this is shown in Figure 2.
<실험예 3> 멜론의 약해 저감효과의 확인<Experimental Example 3> Confirmation of the effect of reducing the damage of melon
작물로 수박 대신 멜론을 사용한 것을 제외하고는 상기 실험예 1과 동일한 방법으로 약해 저감효과를 확인하였고, 이를 도 3에 나타내었다.The damage reduction effect was confirmed in the same manner as in Experimental Example 1, except that melon was used instead of watermelon as the crop, and this is shown in Figure 3.
상기 실험을 통해, 본 발명은 에틸포메이트 2시간 훈증 시 약해가 발생하는 농도구간에 대하여, 훈증 전 탄산수소나트륨(NaHCO3)을 경엽 처리하고 훈증 처리 후 1일 뒤에 박과 작물 3종의 잎 모두에서 약해가 저감됨을 확인하였다. 또한, 탄산수소나트륨(NaHCO3)을 단독 처리한 경우에는 작물의 잎에 영항을 주지 않았다. 특히 에틸포메이트를 7.5 g/m3 내지 10 g/m3 농도로 2시간 동안 훈증 처리 시 수박 잎 끝부분부터 까맣게 되는 약해현상을 확인할 수 있으나, 에틸포메이트 7.5 g/m3 처리구에서 탄산수소나트륨(NaHCO3) 0.5 % 내지 1 % 전처리가 약해를 확연히 감소시킨 것을 확인하였다.Through the above experiment, the present invention treated the foliage with sodium bicarbonate (NaHCO 3 ) before fumigation in the concentration range where mild damage occurs during 2-hour fumigation of ethyl formate, and 1 day after fumigation treatment, the leaves of three types of Cucurbitaceae crops were treated. It was confirmed that weakness was reduced in all cases. In addition, when sodium bicarbonate (NaHCO 3 ) was treated alone, it had no effect on the leaves of the crop. In particular, when fumigating ethyl formate at a concentration of 7.5 g/m 3 to 10 g/m 3 for 2 hours, the weakening phenomenon of blackening from the tips of watermelon leaves can be confirmed, but hydrogen carbonate is removed from the ethyl formate 7.5 g/m 3 treatment group. It was confirmed that pretreatment with 0.5% to 1% sodium (NaHCO 3 ) significantly reduced the toxicity.
