Abstract

Girdling of trunk and rainproof installation over kiwifruit (Actinidia deliciosa) trees were turned out to alleviate bacterial blossom blight effectively in kiwifruit orchards. The disease was most effectively prevented by girdling of tree trunks with 20 mm width around April 10 before about 45 days of flowering stage of kiwifruit, but control efficiencies were not affected by height of girdling on trunks above the ground. Use of a transparent polyvinyl film to protect kiwifruit trees from rain was more effective than windbreak net to prevent the disease, irrespective of kinds of rainproof installation. Installation of partial rainproof vinyl cover over kiwifruit trees around March 10 before about 75 days of flowering stage of kiwifruit prevented most of the disease occurrence on kiwifruit. It is expected that girdling of tree trunks and installation of partial rainproof vinyl cover over kiwifruit trees will be practical as environmentally friendly control methods to manage bacterial blossom blight in kiwifruit orchards.

참다래 과수원에서 환상박피와 비가림시설은 꽃썩음병을 효과적으로 경감시켜주는 것으로 밝혀졌다. 참다래 개화기 약 45일 전인 4월 10일경에 참다래 주간부위에 20${\sim}$30 mm 폭으로 환상박피를 하면 꽃썩음병을 효과적으로 예방할 수 있었는데, 주간부위의 환상박피 높이는 방제효과에 영향을 미치지 않았다. 비닐을 이용한 비가림시설은 파풍망시설보다 비가림방식에 관계없이 꽃썩음병 예방에 효과적이었다. 참다래 개화기 약 75일 전인 3월 10일경에 부분비닐피복식 비가림시설을 하면 참다래 꽃썩음병의 발생을 거의 완벽하게 방제할 수 있었다. 환상박피와 부분비닐피복식 비가림시설은 참다래 과수원에서 환경친화적인 꽃썩음병 방제방법으로 실용화할 수 있을 것으로 기대된다.
