brassica insularis/抗真菌藥

A simple method to determine the toxicity of fungicides on male gametophyte in Brassica campestris subsp. oleiferae is described. The calculation of fungicide concentration used in the test is derived from doses used in field application. The expression of regression curves and calculation of

An antifungal peptide with a molecular mass of 9412 and an N-terminal sequence exhibiting notable homology to those of lipid transfer proteins was isolated from seeds of the vegetable Brassica campestris. The purification protocol entailed ion exchange chromatography on Q-Sepharose, affinity

A set of N-arylbenzenesulfonamides with various substituents at the arylamine and benzenesulfonyl positions were prepared, and their antifungal properties were measured in vitro against such plant pathogenic fungi as Pythium ultimum, Phytophthora capsici, Rhizoctonia solani, and Botrytis cinerea.

The effect of two isolates of the entomopathogenic fungus Metarhizium anisopliae (Metchnikoff) Sorokin (389.93 and 392.93) on root-feeding stages of cabbage root fly, Delia radicum (L.), was studied under glasshouse and field conditions. In glasshouse studies, the effect of drenching a suspension of

An herbal extract mixture and yogurt added to the herbal extract mixture were tested for their protective and therapeutic effects on ethanol-induced liver injury. The herbal extract mixture, yogurt and commercial drugs were used for treatment for two weeks prior to administering a single oral dose

The antifungal activity of fresh, aqueous Brassica oleracea var. botrytis juice against Candida albicans and other pathogenic fungi was investigated. The juice was found to be effective both in inhibiting the growth of blastoconidia and reducing the appearance of C. albicans germ tubes. Furthermore,

Our continuous search for phytoalexins from crucifers led us to examine phytoalexin production in florets of cauliflower (Brassica oleracea var. botrytis) under abiotic (UV light) elicitation. Four known (isalexin, S-(-)-spirobrassinin, 1-methoxybrassitin, brassicanal C) and three new (caulilexins

The activity of several fungicides and of two biocontrol agents, Bacillus subtilis and Ampelomyces quisqualis, alone and in combination, against Erysiphe cruciferarum, causal agent of powdery mildew, was evaluated on turnip under controlled conditions. Among the tested fungicides, quinoxyfen and

The fungicide dexon (p-dimethylaminobenzenediazosulfonate, Na-salt) inhibits the NADH oxidase activity of submitochondrial particles (ETP) from beef heart (semi-inhibition concentration 1.4 muM), while the succinate oxidase activity is unaffected. Measurements of the activity of several enzymatic

During three years, the new fungicide Signum, containing 6.7% pyraclostrobine + 26.7 % boscalid and developed by BASF. has been evaluated in leek, carrots and cabbages in several outdoor field experiments under practical conditions and during one year in outdoor lettuce. In leek, Phytophthora porri

To study physiological and biochemical effects of demethylation inhibitor (DMI) fungicides on non-target insects, larvae of the cabbage moth, Mamestra brassicae L., were exposed orally to propiconazole, (R,S)-1-[2-(2,4-diclophenyl)-4-propyl-1,3-dioolan-2-ylmetyl]-1H-1,2,4-triazole (100, 200 and 600

2,5-Bis(hydroxymethyl)furan monoacetate (BHMF-OAc) compound was isolated from the culture filtrate secreted by Streptomyces sp. CEN26, an endophytic actinomycete found in the root nodes of Centella asiatica (L.) Urban. The compound was purified using various chromatographic techniques and

Two nitro compounds, 2-(4-methoxyphenyl)-1-nitroethane named as lysichitalexin and 2-(4-hydroxyphenyl)-1-nitroethane were isolated as stress metabolites from the leaves of Lysichitum americanum Hultén and St. John treated with cupric chloride. Their structures were determined by spectroscopic

A modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method using multi-walled carbon nanotubes (MWCNTs) as a reversed-dispersive solid phase extraction (r-dSPE) material combined with ultra-high liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) was developed for the

Penconazole is a typical triazole fungicide, which is commonly used to control powdery mildew in vineyard and vegetable field. In this study, the enantioselective dissipation of penconazole in cucumber, tomato, head cabbage, and pakchoi was investigated by field experiments. A sensitive method for
