Powdery mildew, caused by Sphaerotheca aphanis var. aphanis, is an economically significant disease of strawberry in Korea. When powdery mildew is not controlled adequately, it often spreads rapidly through strawberry plants and damage is associated with reduced yields. Proper timing of fungicide applications is, therefore, essential for effective disease control. This study evaluated the efficacy by application schedule of fungicides before harvest stage for preventing powdery mildew in 2001-2003. The systemic fungicides, azoxystrobin, kresoxim-methyl, and cupper fungicide DBEDC were applied preventively during the first part of the cultivating season. Preventative applications of DBEDC by dipping treatment before transplanting and kresoxim-methyl by foliar spray before blooming stage were one of the most effective control schedule tested to prevent and manage this disease. This research demonstrated the significance of application time to control of powdery mildew, particularly provided elimination unnecessary sprays of agrochemicals and reduction costs for strawberry growers.

벼멸구를 방제하기 위해 친환경농자재를 이용할 때 중요한 것은 방제시기와 방제횟수이다. 대부분의 친환경농자재는 벼멸구의 알을 죽이지 못하므로 벼멸구 발생초기에 10일 간격으로 2회 이상 처리해야 살아남은 알에서 새로 부화한 벼멸구까지 방제가 가능하다. 농가에서 주로 사용하는 친환경농자재의 벼멸구 방제효과에 대해 알아보자.

''2종 또는 그 이상의 작용특성이 상이한 약제의 혼합제제는 작물의 재배기간중 동시에 발생하는 병해충을 효율적으로 방제할 수 있고 저항성해충에 대한 안전방제, 방제시기 일실에 의한 피해의 최소화가 가능하며 살포회수를 줄여 노동력을 절감할 수 있고 단위면적당 살포주성분량 절감으로 농약가격을 낮출수 있다 ''

A series of experiments was carried out for selecting insecticides and determining proper spraying time to control pea weevil (Bruchus pisorum Linnaeus) in Jeonnam area. In the field trial two times spray with diazinon, carbaryl, imidacloprid, spinosad, etofenprox, clorpyrifos-methyl showed good control effect and threetimes spray showed the better control effect. The second spray (spraying on 10th of May) took the major role of insecticide effectiveness expression for controlling pea weevil. Further trial for selecting insecticides among organophosphates to control pea weevil in lab was conducted and every organophosphate insecticide tested was very effective to pea weevil even at the concentration of one forth of its recommending concentration.

연 1회 발생하며 성충태로 대부분이 양지바른 산지의 돌밑이나 낙엽밑 또는 논뚝 일부에서 월동하는 벼먹노린재는 작물종류나 경종양식이 다양화하면서 최근들어 국지적으로 문제되고 있다. 가해가 가장 심한 시기는 수잉기에서 출수기에 걸쳐서인데 이 때까지는 피해가 잘 눈에 띄지 않는다. 그러나 백수가 보이면서 갑자기 눈에 띈다
