Abstract

This study was conducted to select excellent tank mix combinations of pesticides for aerial application by manned helicopter. Among 209 pesticide combinations of 3-way tank-mixing for aerial application, a total of 93 recommendable combinations including tricyclazole SC+validamycin-A SL+imidacloprid SL were finally selected for the simultaneous control of key pests on paddy rice such as blast, sheath blight, brown planthopper and moth. The selected combinations were not phytotoxic to rice plants and nearby non-target crops, and excellent in physicochemical properties of ultra low volume (ULV) spray solutions. The efficacies on sheath blight, brown planthoppers and white-backed planthoppers of pesticides sprayed by aerial application were similar to those of pesticides by conventional spraying. Total cost of aerial application in paddy rice was very economical as one fourth level of that of conventional spraying.

벼의 주요 병해충인 도열병, 잎집무늬마름병, 벼멸구 및 나방류를 동시에 방제할 수 있는 항공방제용 고농도 소량살포 가능 농약혼용조합 209조합에 대하여 시험한 결과, 벼는 물론 주변작물에 약해가 없고 살포액의 물리성이 양호한 tricyclazole SC + validamycin-A SL + imidacloprid SL 등 우수 혼용조합 93 조합을 최종 선발하였다. 선발된 조합의 항공살포에 의한 약효는 일반살포의 방제효과와 비슷하였다. 또한 유인헬기에 의한 항공방제는 일반 관행살포에 비해 방제비용을 1/4 수준으로 크게 줄일 수 있음을 확인하였다.
