| design, synthesis, antifungal activities and 3d-qsar of new n,n'-diacylhydrazines containing 2,4-dichlorophenoxy moiety. | a series of new n,n'-diacylhydrazine derivatives were designed and synthesized. their structures were verified by 1h-nmr, mass spectra (ms) and elemental analysis. the antifungal activities of these n,n'-diacylhydrazines were evaluated. the bioassay results showed that most of these n,n'-diacylhydrazines showed excellent antifungal activities against cladosporium cucumerinum, corynespora cassiicola, sclerotinia sclerotiorum, erysiphe cichoracearum, and colletotrichum orbiculare in vivo. the half ... | 2013 | 24189221 |
| plant-mediated interactions between insects and a fungal plant pathogen and the role of plant chemical responses to infection. | diverse organisms simultaneously exploit plants in nature, but most studies do not examine multiple types of exploiters like phytophagous insects and fungal, bacterial, and viral plant pathogens. this study examined patterns of induction of antipathogenic peroxidase enzymes and phenolics after infection by the cucurbit scab fungus, cladosporium cucumerinum, and then determined if induction mediated ecological effects on colletotrichum orbiculare, another fungal pathogen, and two insect herbivore ... | 1998 | 28308273 |
| the effect of gamma irradiation on the properties of cucumber. | in this study, the effect of gamma irradiation on the shelf life and properties of cucumber was investigated. these properties include weight reduction, fruit density, juice, tissue firmness, total soluble solids (tss), total titratable acidity, chlorophyll and vitamin c, ph, marketability, flavor, frostbite and fungal effects. for this purpose, cucumbers were irradiated with dose of 2, 2.5 and 3 kgy. the exposure time was calculated by mcnp4c; the monte carlo particle transport code. three type ... | 2017 | 29184234 |
