Sensitivity of 24 isolates of Colletotrichum destructivum O'Gara, collected from alfalfa plants in Serbia, to eight selected fungicides, was investigated in this study. Molecular identification and pathogenicity test of isolates tested were also performed. Fungicide sensitivity was evaluated
Both metam sodium and copper/zinc-containing compounds are widely used as fungicides. They therefore may co-occur in the biosphere. Despite certain studies of individual toxicity for either metam or copper (II)/zinc (II), their synergistic toxicity has not been examined. In this paper, a remarkable
We previously found that ziram, a carbamate fungicide, significantly induced apoptosis and necrosis in human NK-92MI, a natural killer cell line. To investigate whether other carbamate pesticides also induce apoptosis and necrosis in human natural killer cell, we conducted further experiments with
In agroecosystems, a variety of pesticides may enter aquatic habitats exerting a number of toxic effects on living organisms. Due to their wide use and the repeated application, fungicides can be found at a much greater concentration than other agrochemicals in all environmental compartments. One of
The chronic toxic effects of a prolonged exposure of 6 months, from January to June, to a 'safe dose' (0.20 mg litre(-1)) of a commercial organomercurial fungicide, Emisan (methoxy ethyl mercuric chloride: MeEHgCl), on the histophysiology of liver in adults and young (yearlings) of Channa punctatus,
Strawberry anthracnose fruit rot and root necrosis, caused by Colletotrichum acutatum, are primary limiting factors in fruit production fields in the United States. Recent research focusing on the phenotypic and genetic characteristics of this species has shed light on the diversity of the
Alternaria dauci and Cercospora carotae cause foliar blight on carrot and can reduce yield in severely blighted fields. Historically, fungicides are applied every 7 to 14 days even though applications may be made when environmental conditions do not favor blight development. The purpose of this
A large number of carboximides have been synthesized, tested and, in some cases, marketed as agricultural fungicidal agents. One carboximide fungicide N-(3,5-dichlorophenyl)succinimide (NDPS) proved to be both highly efficacious as a fungicide and a nephrotoxin. The purpose of this study was to
Ziram as a dithiocarbamate fungicide is widely used throughout the world in agriculture and as an accelerating agent is used in latex production. In order to investigate ziram-induced apoptosis/necrosis and its underlying mechanism in human immune cells, a human monocyte-like cell line (U937) was
Acriflavine is an antiseptic, fungicide, and effective agent against parasitic infections, inducing petite mutation in the yeast Saccharomyces cerevisiae and kinetoplast loss in Trypanosomidae. Here we showed that acriflavine caused both apoptosis and necrosis in the yeast Candida utilis. Cells were
ABSTRACT Take-all, caused by Gaeumannomyces graminis var. tritici, is a damaging disease of wheat that remains difficult to control. The efficacy of an experimental fungicide, applied as a seed treatment, was evaluated in five naturally infested field experiments conducted during three cropping
Acute toxicity of the fungicide, captan, to juvenile rainbow trout was evaluated under static-renewal test condition. Actual concentrations of captan ranged from 0.05 to 1.00 mg/L. The concentrations of captan that killed 50% of the rainbow trout (3.11±0.8 g) within 24 (24 h; LC(50)), 48, 72 and 96
Optimum timing and use of fungicides for disease control are improved by an understanding of the characteristics of fungicide physical mode of action. Greenhouse and field experiments were conducted to quantify and model the duration of pre- and postinfection activity of fungicides most commonly
Paecilomyces rot of apples is a postharvest disease caused by the thermotolerant fungus Paecilomyces niveus (Byssochlamys nivea). The etiology of disease and the activity of fungicides against P. niveus are not yet well understood. This study evaluated the ability of P. niveus to infect 'Gala'
Amphibian habitats are easily contaminated by several pollutants, and in agricultural landscapes the likely exposure scenario is represented by pesticides. Many of these substances are known or suspected to act as endocrine disrupting chemicals (EDCs). The goal of the present study was to assess the
