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 regression equations require the logarithmic transformation of fungicide concentration. The range of th...

Study Examines Epigenetic Effects of Fungicide Exposure A mother’s environmental exposure can result in transgenerational effects that are inherited through successive generations, even in the absence of exposure of the offspring. A new proof-of-principle study reports that great-grandchildren of rats exposed to the common fungicide vinclozolin showed a more profound behavioral and neurodevelop...

An efficient synthesis of highly functionalized chiral β-amino ester derivatives containing benzothiophene and benzothiazole moieties is developed by a Mannich-type reaction using a cinchona alkaloid-derived thiourea catalyst. The desired products were obtained in good yields and high enantioselectivities (~86% yield, >99% ee) using to the optimized reaction conditions. The synthesized compound...

Pseudomonas fluorescens strain LRB3W1 inhibited the mycelial growth of Fusarium oxysporum f. sp. lycopersici and suppressed the Fusarium wilt of tomato. The chemical fungicide, benomyl, did not suppress the disease incidence at low concentrations. However, the disease incidence was decreased by the combined application of benomyl at low concentrations with strain LRB3W1. Combined application of...

oil on 15 clinical strains of Candida spp., isolated from humans and dogs and to determine if there is a difference in susceptibility between human and dog isolates. Sampling in patients with stomatitis was done by swabbing the denture or oral mucosa swab while sampling in dogs was done by swabbing the oral cavity mucosa after stomatitis has been diagnosed. In order to investigate the antifunga...

Essential oils are natural compounds, which have extensive applications in perfumery, food and pharmaceutical industries. Nowadays they are also used in preservation of foods and disinfectant production. Considering the undesirable effects of synthetic compounds on the nature and living beings, using natural compounds like essential oils have been noticed recently. Peppermint (Mentha piperita) ...

Macrophomina phaseolina (Tassi) Goid is a soil-borne fungal pathogen that causes root rot disease in more than 500 plant species but no registered fungicide is available for its control. The present study was carried out to investigate the antifungal activity of aqueous leaf extracts of Azadirachta indica A. Juss., Melia azedarach L. and Toona ciliata Roxb. (Meliaceae) against M. phaseolina. Aq...

Complex II inhibitors play an important role in agrochemical fungicide research and have been known for more than 40 years. With the introduction of ortho-substituted heterocyclic amides, a breakthrough in activity level and spectrum within this class was achieved. In the meantime all major agrochemical companies have entered this field. In this paper, a special complex II subclass, the pyrrole...

Copper-based fungicides can be effectively digested by treatment with a mixture of concentrated sulfuric and nitric acid in exactly 15 minutes for the rapid determination via copper using flame atomic absorption spectrometry (AAS). Under optimum conditions, the results of copper fungicide analysis were consistent to those obtained by the AOAC’s recommended method. Recovery values ranged from 98...
