Abstract

Xanthomonas arboricola pv. pruni causes black spot symptom on fruit of plum, resulting in yield loss by reduction of marketable fruit production. To develop an effective control program, some chemicals were sprayed in various scheme during dormant season and growing season after blooming period. Copper-based chemicals were sprayed during dormant season and antibiotic-based chemicals were sprayed during fruit growing season. Sprays of antibiotic-based chemicals in growing season was more effective than copper-based chemicals sprays in dormant season. Three applications of antibiotic-based chemicals in 10 days interval starting 10 days after full blooming controlled disease incidence as much as 93%, whereas applications of copper-based chemicals in dormant season controlled 26-42%. Antibiotic-based chemicals application starting 10 days after full blooming was more effective than starting 20 or 30 days after full blooming.

자두 검은점무늬병은 Xanthomonas arboricola pv. pruni에 의한 세균성 병해로 과실표면에 검은 반점형태의 병징이 발생하여 과실 상품성을 저하시켜 자두 재배농가에 큰 경제적 손실을 초래하는데 이러한 자두 검은점무늬병에 대한 효과적인 약제 방제체계를 개발하기 위하여 몇 종의 화학약제와 살포체계를 구성하여 휴면기중에는 동제 약제를 그리고 과실생육기중에는 항생제계열 약제를 살포하였는데 과실생육기중에서의 항생제계열 약제살포는 휴면기중의 동제 약제살포보다 높은 방제효과를 나타내었다. 자두의 개화만개 10일 후부터 10일 간격으로 3회의 항생제계열 약제살포는 93%의 높은 방제가를 얻을 수 있었는데 비해서 휴면기중의 동제 약제살포는 26-42%의 낮은 방제가를 얻는데 그쳤다. 또한 항생제계열 약제의 처음 살포시기가 개화만개 후 20일이나 30일 보다는 개화만개 후 10일에서 더 높은 방제효과를 얻을 수 있었다.
