Abstract

We studied on pesticide residue and pest control effect when using various types of sprayers on paprika cultivation. Additionally, a test was conducted to optimize chemical content per unit area in condition of optimum pest control. Two types of sprayer were tested (three times) on paprika cultivation which was divided into seven sections. Blind spots were also examined using a water sensitive paper when spraying chemical pesticide, remote controlled sprayer were confirmed to be not effective in terms of its spraying capacity. However, a U-shaped sprayer was confirmed that it sprayed enough on all the parts of a plant in green house including the blind spots. Additionally, it does not exceed the minimum residue limits on the all parts of pesticides residue conditions. When using remote controlled sprayer, water sensitive paper were changed to blue color (82.5% and 81.2%) in terms of controlling Bemisia tabaci and Aphis gossypii based on the two spraying manners. 53.0% and 42.6% of control effect were shown on the fair parts of the plants. However, on the poor parts on which pesticides were not well-sprayed, thus, not-remained, more number of pests increased. Meanwhile, on farming that only one type of pesticide has been used, resistance pests present with very low control effect, even though sufficient amount of pesticide was well-sprayed. On the test of the optimum amount of spraying per a unit area, which shows no differences in the two cases of using 5L and 2.5L of chemical pesticides on 9 plants of paprika that has 81.8% and 84.5% control effect, respectively.

유리온실내에서 파프리카에 살포되는 분무기의 종류에 따라 살포되는 농약 부착량과 해충방제정도에 대하여 검토하였다. 또한 해충의 최적방제조건에서 단위면적당 농약함량을 최적화하기 위한 시험이 시도되었다. 파프리카 시설재배지에 두 종류의 분무기로 적절하게 7개구간으로 나누어 3반복 실험을 수행하였다. 농약 살포할 때 발생되는 사각지대를 감수지로 조사하였을 때 무인연무기는 하우스내의 식물에 골고루 부착하지 못하였으며 고압식 U자형분무기 모든 식물에 충분하게 부착되었다. 또한 살포된 농약 잔류조건에서 모든 부분에 최저잔류농도허용치를 초과하지 않았다. 살포조건에 따른 해충방제에서 담배가루이와 목화진딧물은 미세한 물방울 형태로 분무되는 무인연무기 Pyrifluquinazon 10% 입상수화제를 살포하였을 때 감수지가 청색으로 변한 부분은 각각 82.5%와 81.2%이며, 중간부분은 각각 53.0%와 42.6%의 방제효과가 나타났다. 그러나 농약이 부착되지 않은 아래 부분은 해충발생이 방제전보다 더 증가하였다. 한편 농가에서 하나의 약제를 수년 동안 반복하여 사용한 경우에는 약액이 충분하게 부착되었어도 매우 저조한 방제효과로 저항성 경향이 나타났다. 단위면적당 최적 살포량을 위한 실험에서는 9그루 파프리카 잎에서 약액이 흘러내릴 정도로 충분하게 살포하였을 때는 5 l에서 81.8% 그리고 1/2물량인 2.5 l에서는 84.5%로 매우 유사한 방제효과로 나타났다.
