딸기$\cdot$시들음병에 대한 실용적인 약제방제법을 규명하기 위하여 본 시험을 실시하였다. 이 균이 균사생장과 후막포자 발아의 저지효과에 있어서 Captafol이 가장 효과적이었으며 Benomyl도 저지효과가 현저하였다. 포장시험에서는 Captafol, Benomyl, Thiophanate-methly의 토양근주의 효과가 비교적 우수하였다. Captafol.의 토양근주에 의하여 본 병원균의 토양내 균량은 크게 감소되었으며, Trichoderma sp. 의 균량은 오히려 증가되었다.

Date palm (Phoenix dactylifera) is an important fruit and cash crop in Sultanate of Oman, occupying nearly 60% of the total cultivated area. However, leaf spots caused by Mycosphaerella tassiana, Alternaria spp., and Dreshcleri sp. have become a threat to date palm's cultivation in recent years. In this study, a field experiment was conducted to find out a suitable chemical spray program to control the disease. A prophylactic spray schedule with mancozeb (Dithane M45), copper oxychloride (Champion), and mancozeb+copper (Trimiltox) effectively controlled the disease when applied at a time when the disease severity index (DSI) was low, ranging from 0 to 1.68. Meanwhile, the disease did not decrease, but instead increased gradually, when the fungicide combination was applied when DSI was high, ranging from 1.78 to 5.37. It was concluded that fungicides should be applied at the early stage or before disease initiation in order to control the disease effectively.

Methoxyiminoacetate and methoxyiminoacetamide derivatives possessing 2,2-dichlorovinyl side chains, have been synthesized and their biological activities against six representative plant fungal pathogens have been evaluated. Five substances in this series (3a, 4a, 3b, 3d, and 4d) were found to exhibit potent fungicidal activities compared to those of the commercially available fungicides, azoxystrobin and fenarimol.

대추 중 boscalid와 pyraclostrobin의 잔류량을 조사하여 약제별 잔류소실과 생물학적 반감기를 산출하였다. 노지재배 중인 대추에 안전사용기준 농도로 희석한 boscalid와 pyraclostrobin을 다른 두 지역의 포장에서 각각 살포 후 0 (2시간), 1, 3, 5, 7, 10, 14일에 시료를 채취하여 HPLC/DAD로 분석하였다. 두 시험농약의 방법정량한계는 $0.02mg\;kg^{-1}$이었으며 시험분석법의 회수율 결과, boscalid는 101.8~109.3%, pyraclostrobin은 104.2~115.4%이었다. 저장안정성시험 결과, boscalid는 101.9~106.5%, pyraclostrobin은 104.6~110.6%이었으며 회수율시험 및 저장안정성 시험 결과 CV값이 5% 미만이었다. 대추 중 boscalid의 초기 잔류량은 포장 1에서 $0.40mg\;kg^{-1}$이고 포장 2에서 $0.48mg\;kg^{-1}$이었으며, pyraclostrobin의 초기 잔류량은 포장 1에서 $0.76mg\;kg^{-1}$이고 포장 2에서 $0.57mg\;kg^{-1}$이었다. 대추 중 boscalid의 생물학적 반감기는 포장 1에서 11.0일, 포장 2에서 13.2일 이었으며, pyraclostrobin의 생물학적 반감기는 포장 1에서 6.1일, 포장 2에서 12.7일이었다.

The effects of prochloraz on membrane permeability and germination of uredospores of Puccinia recondita were investigated to determine its potential mode of action on wheat leaf rust control activity. Disease control activity of ergosterol biosynthesis inhibitors (EBIs) and their activities on uredospore membrane permeability and germination were examined with wheat leaf rust pathogen, both in vitro and in vivo. While wheat leaf rust was not controlled by prochloraz, electrolytic leakage and spore germination of P. recondita uredospore was the highest with the use of prochloraz among the eight fungicides tested. Prochloraz stimulated uredospore of P. recondita to germinate at a higher ratio. Although certain EBIs, such as hexaconazole, showed excellent control activity, their effects on uredospore membrane permeability and germination was much inferior to prochloraz. Therefore, results of this study suggest that effects of EBIs on membrane permeability and germination of uredospore are not always correlated with their disease control activity.

In order to establish an appropriate spray schedule to reduce the infection, 11 kinds of chemicals were tested for their properties on the inhibition of spore germination at the surface of apple fruits and the duration of the inhibitory effect after spray of each chemical was examined from late June to early September with basically 10 day intervals. Actual control efficacy of each chemical by the 8 successive spray and the patterns of waterborne spore dispersals during that periods were also examined. Combining those results with the meteorological observation data, actual control efficacy of each chemical in the given periods could be estimated. It was revealed that folpet, Brodeaux mixture, mancozeb, oxine copper and imminoctadine-triacetate could be used at any time during the possible infection periods. Captan and dithianon could also be used except the rainy season due to the short duration of inhibitory efficacy against spore germination under heavy rain. However, the usefulness of propineb, benomyl and chlorothalonil against the apple white rot could not be demonstrated in this experiment. Thiram, even though has not been used for apple white rot, can also be used before or after the rainy season to control not only white rot but also alternaria blotch.

딸기탄저병의 방제방법을 개발하기 위해 배지에서 약제별 균사생장억제정도를 검정한 결과 Tricylazole수화제가 가장 좋은 효과를 보여 주었으나 딸기잎에 접종하여 효과를 검정하였을 때는 Azoxystrobin 수화제가 가장 좋은 효과를 보여주었다. 포장에서 방제효과는 관주 및 엽면살포는 방제효과가 없었으나 Azoxystrobin 수화제 1,000배액에 10분간 침지시 우수한 방제효과를 보여 주었고 처리시간과 처리농도간 약효의 차이는 볼 수 없었다.

In attempt to lead compounds exhibiting both insecticidal and fungicidal activities, a series of O-benzyl oximeether derivatives were designed and synthesized by introducing ${\beta}$-methoxyacrylate pharmacophore into a scaffold. The insecticidal activity against Aphis fabae and the fungicidal activity against Erysiphe graminis were screened. The title compounds exhibited remarkable insecticidal and fungicidal activities. The most potent compound 6d was identified. Its insecticidal $LC_{50}$ against A. fabae is 6.4 mg/L, which is lower than that of chlorfenapyr (19.4 mg/L) and even close to the level of imidacloprid (4.8 mg/L). Its fungicidal $EC_{90}$ in preventive and curative treatment against E. graminis are 2.2 and 4.8 mg/L, respectively, which are lower than azoxystrobin (7.0 and 5.9 mg/L). These results indicate that compound 6d can be considered as a lead for further developing new O-benzyl oxime-ether typed candidates with both fungicidal and insecticidal activities.

Collectotrichum acutaum 에 의해 발생하는 탄저병은 매년 고추 생산에서 수량과 품질을 감소시켜 고추 병해 중 가장 큰 피해를 주는 병해로 알려져 있다. 본 연구는 고추 탄저병 방제 시 유기농업자재와 화학농약의 교호살포로 화학농약의 사용량을 감소시키기 위한 방제 전략을 개발하기 위하여 수행되었다. 고추 탄저병에 대한 유기농업 자재와 화학농약의 교호살포 효과는 실내와 포장에서 확인하였다. 첫 번째로 13종의 미생물농약과 22종의 유기농업 자재들을 대상으로 탄저병 병원균의 생장억제시험과 생물검정을 실시하였다. 시험결과 1종의 미생물농약(Bacillus subtilis QST-713 액상수화제)과 3종의 유기농업자재(유황, 보르도액, 해조류 추출물)에서 탄저병 병원균에 대해 높은 억제효과를 나타내었다. 포장시험에서 유기합성 살균제(Iminoctadine tris+thiram)를 단용처리 하였을 때 89.5%의 방제효과가 있었으며, 반면에 유황, 보르도액, 구리, 해조류 추출물 그리고 Bacillus subtilis QST-713 액상수화제를 단용처리 하였을때에는 33.1-81.0%로 유기합성 살균제와 비교하여 방제효과가 낮은 것으로 조사되었다. 하지만 유기합성 살균제와 유기농업자재를 7일 간격으로 2회씩 교호살포하게되면 유기합성 살균제+보르도액 교호살포는 81.7%, 유기합성 살균제+해조류 추출물은 87.1%의 방제효과가 있는 것으로 확인되었다. 결론적으로 두 가지의 교호살포 방제체계는 화학농약의 살포횟수 및 사용량을 절감 할 수 있는 가능한 방안으로 추천할 수 있을 것이다.

Even though many pesticides are known for barley powdery mildew and wheat leaf rust, alternative controls are necessary, because of consumer rejection of chemical pesticides and the appearance of fungi resistant to fungicides. To discover biopesticides, many broths of microorganisms were screened. Of those, a culture broth of Burkholderia ambifaria showed an excellent antifungal activity against both Erysiphe graminis and Puccinia recondita, which cause barley powdery mildew and wheat leaf rust, respectively.
