  • 금년의 과수농사는 개화기에 다소 많은 비가 내렸고 강풍이 불어 다소 어려울 듯 하였으나 그후 생육기에는 안정되어 예년에 비하여 10$\%$정도 증수될 것으로 추정되고 있다. 이와같은 결과는 기상의 안정에 힘입은 바 크지만 농민들의 피와 땀의 결정이고 병충해 방제 및 모든 어려운 일을 슬기롭게 이겨낸 덕분이라 믿는다. 특히 금년 여름은 무던히도 더웠던 탓으로 후기에 굴나방, 점박이응애, 진딧물등 해충의 발생이 지역에 따라 심하였으며 과실의 숙기가 빨라진 탓으로 탄저병과 부패병(겹무늬병)이 약 20일 정도 일찍 발생되어 약제 방제를 소홀히 한 지역에서는 크게 문제가 되었다. 따라서 금년도의 기상과 병충해 발생 정도를 분석 진단하여 내년도 농사에 보탬이 되었으면 하고 과수별 주요 병해충을 진단해 보고자 한다.

  • Control efficacies of mixing of powdery mildew biofungicides with other control agents against major or fungal diseases of cucumber were investigated. Control efficacies against cucumber powdery mildew were quite different according to the kinds of biofungicides applied but those of powdery mildew biofungicides were increased by mixing application of two biofungicides. More than 80% of control efficacies on powdery and downy mildews of cucumber were obtained by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and a downy mildew chemical fungicide dimethomorph. Similarly, control efficacies on powdery and downy mildews of cucumber were 95% and 70% by mixing application of a powdery mildew biofungicide Bacillus subtilis KB-401 and cooking oils and yolk mixture, respectively.

  • Gyoungok-go (GOG; Qiongyu-gao in Chinese) has been used in traditional oriental medicine for the improvement of various physiological vitality functions. The aim of present work is to investigate a processing possibility of vinegar using GOG. GOG vinegar was prepared by two stage fermentations of alcohol and vinegar. The method of GOG fermentation with polished rice as a fermentation substrate is not yet established. The result of alcohol fermentation rate of GOG with some strains, strain No. 1 produced the highest alcohol contents among 7 strains. The strain No. 1 identified Saccharomyces paradoxus by 18S rDNA classification. S. paradoxus was produced over 20% alcohol in the 1$\sim$11% GOG with polished rice. A. aceti was produced 8.52% acetic acid from 6.5% alcohol containing 11% GOG, after incubation for 11 days.
