Chloropicrin은 국내에서는 사용되지 않으며, 잔류허용기준이 불검출로 설정된 농약이다. 그러나 중국에서는 훈증제, 살균제, 살선충제 및 저장 곡물의 살충제로 사용되고 있으며, 잔류허용기준이 설정되어 있다. 따라서 본 연구에서는 중국 등에서 수입하는 식품 중 국내에서 사용하지 않는 농약에 대한 안전성을 확보하기 위하여 해당 농약을 신속하고 빠르게 검출할 수 있는 시험법을 개발하고자 하였다. Chloropicrin은 분자량이 작고 휘발성이 큰 화합물이므로 헤드스페이스 추출법을 활용하여 검체 추출액을 직접 GC에 주입하는... -

these once-dominant nematicides are no longer available due to their adverse effects in the environ- ment (Regmi and Desaeger, 2020; Sande et al., 2011). Consequently, more fumigants such as chloropicrin, 1,3-dichloropropene, 1,2-dibromo-3-chloropropane, form- aldehyde, and metam sodium among others, were devel- oped in the first and the early second half of the 20th centu- ry. And despite the... The global nematicides market is expected to continue growing. With an increasing demand for synthetic chemical-free organic foods, botanical nematicides are taking the lead as replacements. Consequently, in the recent years, there have been vigorous efforts towards identification of the active secondary metabolites from various plants. These include mostly glucosinolates and their hydrolysis products such as isothiocyanates; flavonoids, alkaloids, limonoids, quassinoids, saponins, and the more... -

cultivars are not entirely immune to FW infection under high disease pressure (LaMondia, 1995). Therefore, FW chemical management, through pre-planting soil fumiga- tion with methyl bromide or chloropicrin, is common- place in many plant production systems (Duniway, 2002). However, methyl bromide is now recognized as a Class I ozone-depleting substance and its use has been phased out (UNEP... Fusarium wilt in tobacco caused by the fungus Fusarium oxysporum f. sp. nicotianae is a disease‑management challenge worldwide, as there are few effective and environmentally benign chemical agents for its control. This challenge results in substantial losses in both the quality and yield of tobacco products. Based on an in vitro analysis of the effects of different phenylpropanoid intermediates, we found that the early intermediates trans‑cinnamic acid and para‑coumaric acid... -

Hong et al. 164 controlled by cultivation methods, such as covering fields with black vinyl or silver polyethylene films (Ashworth and Gaona, 1982; Kodama and Fukuit, 1982). Soil fumi- gation with chloropicrin, dichloropropenes and dichloro- propane are known to reduce the pathogen density in soil. Soil solarization is one of process for soil sterilization that use transparent plastic film for... Strawberry Fusarium wilt disease, caused by Fusarium oxysporum f. sp. fragariae, is the most devastating disease in strawberry production. The pathogen produces chlamydospores which tolerate against harsh environment, fungicide and survive for decades in soil. Development of detection and quantification techniques are regarded significantly in many soilborne pathogens to prevent damage from diseases. In this study, we improved specific-quantitative primers for F. oxysporum f. sp. fragariae to... -

(98% methyl bromide and 2% chloropicrin), with the following characteristics was used 82% sand, 13% silt, and 5% clay; pH 7.1; 21 mg dm 3 P; 1.1 cmolc dm 3 K; 4.7 cmolc dm 3 Ca; 1.3 cmolc dm 3 Mg; 0.07 cmolc dm 3 Na; 13.3 g dm 3 MO (organic material), and 9.64 cmolc dm 3 CTC (cationic exchange capacity). Vegetable material. Micropropagated A. purpurata plantlets were multiplied in MS medium... An experiment was conducted to evaluate the tolerance of micropropagated and mycorrhized alpinia plants to the parasite Meloidogyne arenaria. The experimental design was completely randomized with a factorial arrangement of four inoculation treatments with arbuscular mycorrhizal fungi (AMF) (Gigaspora albida, Claroideoglomus etunicatum, Acaulospora longula, and a non-inoculated control) in the presence or absence of M. arenaria with five replicates. The following characteristics were evaluated... -

of raised beds previously fumigated with methyl bromide:chloropicrin (67:33) at 393 kg/ha and covered with metalized poly- ethylene mulch (Canslit Inc., Victoriaville, QC, Canada). The beds were 15 cm high by 76 cm wide, and with 2.74 m between bed centers. In field trial 1, summer squash HMX 5703 F1 hybrid (Harris Moran Seed Co., Modesto, 530 ..PAGE:4 Managing Powdery Mildew in Squash by... Although many fungicides are registered for use to control powdery mildew on cucurbits, management of resistance to fungicides in pathogen populations still remains a major challenge. Two biopesticides Regalia SC and HMO 736 were evaluated in the greenhouse and field for their efficacy against powdery mildew in squash. In greenhouses, Regalia SC alone significantly (P ; 0.05) reduced powdery mildew compared to the nontreated control, and was as effective as the chemical standard Procure 480SC... -

Franks et al., 2008; Schell, 2000). For the disease control of tomato bacterial wilt disease, multidirectional controls including cultural, biological and chemical methods have been applied so far. Chloropicrin was suggested as the most promising chemical for reducing tomato bacterial wilt when it was used as soil fumigant before transplanting (Enfinger et al., 1979). However, it can be irritating... Reactive oxygen species (ROS) generation in tomato plants by Ralstonia solanacearum infection and the role of hydrogen peroxide (H2O2) and nitric oxide in tomato bacterial wilt control were demonstrated. During disease development of tomato bacterial wilt, accumulation of superoxide anion (O2 -) and H2O2 was observed and lipid peroxidation also occurred in the tomato leaf tissues. High doses of H2O2 and sodium nitroprusside (SNP) nitric oxide donor showed phytotoxicity to detached tomato leaves... -

methyl bromide and chloropicrin, but the cost of the fumigation is not practical for wheat (Cook, 2003) and methyl bromide has been banned because it destroys the ozone layer. Some micro- tubule assembly inhibitors (benzimidazole and triazole) and sterol biosynthesis-inhibiting fungicides (triadimenol and nuarimol) gave significant control of take-all in naturally infested fields, but the results... In agro-ecosystems worldwide, some of the most important and devastating diseases are caused by soil-borne necrotrophic fungal pathogens, against which crop plants generally lack genetic resistance. However, plants have evolved approaches to protect themselves against pathogens by stimulating and supporting specific groups of beneficial microorganisms that have the ability to protect either by direct inhibition of the pathogen or by inducing resistance mechanisms in the plant. One of the best... -

1,3-D, chloropicrin과 조합하여 처리한 경우 단일 처리보다 뿌리혹선충 방제 효과가 더 높게 나타났다고 하였다(Desaeger 등, 2008). 본 연구는 단일 제제를 일반 두께 0.02 mm의 검정색 저밀도 PE 필름으로 피복한 실험으로 추후 복합제제와 피복제 로 VIF을 사용하면 지금보다 더 낮은 처리 약량에서도 효과적 인 방제 효과를 거둘 수도 있지 않을까 예상해본다. 본 연구에서 고려한 요인 중의 하나인 토양 소독제의 처리 깊... 클로버씨스트선충은 국내 고랭지배추 재배지에서 가장 문제 되고 있는 식물기생선충 중 하나이다. 본 연구는 새로 개발한 훈증성 약제 처리기의 성능을 시험하기 위하여 고랭지배추 문 제 클로버씨스트선충을 대상으로 훈증성 약제 2종(dimethyl disulfide [DMDS], metam sodium [MNa])의 살선충 활성을 검 정하였다. 훈증성 약제의 방제 효과는 약제 처리 4주 후 처리구 별 토양으로부터 씨스트를 채집하여 클로버씨스트선충 알 부 화율을 조사하였고, 씨스트 내부의 알을 배추에 접종하여 얻 은 암컷 증식 수를 조사하여 평가했다.
