Rhizoctonia solani is an important soil-borne pathogen which has a broad host range and cause damping-off or rottenness of root and crown of cultivated plants. The combined use of different control methods in IPM programs is an effective strategy against pathogens and is useful especially in resistance management programs. In this study, EC50 and EC25 values of three conventional chemical fungi...

Chemical management of dollar spot in turf may lead to the development of Sclerotinia homoeocarpa populations with reduced fungicide sensitivity. The objective of this study was to investigate resistance of S. homoeocarpa isolates to triazole fungicides and to test cross-resistance among three triazole fungicides. A total of 66 isolates of S. homoeocarpa were collected from 15 golf courses acro...

This study was designed to evaluate the role of growth regulator trinexapac and fungicides on growth, yield, and quality of winter rapeseed (Brassica napus L.). The experiment was conducted simultaneously at different locations in Germany using two cultivars of rapeseed. Five different fungicides belonging to the triazole and strobilurin groups, as well as a growth regulator trinexapac, were te...

Fungicides are important tools for managing diseases in many crops. Unlike insecticides and some herbicides which kill established insects or weeds, fungicides are most commonly applied to protect healthy plants from infection. To be effective, fungicides must be applied before infections become established and in a sufficient spray volume to achieve thorough coverage of the plant or treated ar...

Fungicides are applied to turf to prevent the growth or penetration of disease-causing fungal organisms. Fungal organisms cause more diseases on turf than other microorganisms (Wong, 2006). Fungicides are the class of pesticides used to control fungal organisms, and they can be catego­ rized into many different groups based on their biochemical mode of action (MOA) and chemical structure. Addit...

Fungicides viz., Benomyl, TopsinM, Carbendazim and Cuprocaffro were used at different concentrations i.e., 0, 1, 10, 100, 1000 and 10,000 ppm a.i. to evaluate Trichoderma species viz. T. harzianum, T. pseudokoningii, T. longibrachiatum, T. viride for tolerance to fungicides. Topsin-M and Carbendazim were the most effective fungicides that inhibit the growth of Trichoderma species even at low co...

The effect of five fungicides and tea extracts was tested against anthracnose disease and leaf spot of Azalea during summer (2015) at the laboratory in Rasht Branch, Islamic Azad University. Commercially formulated fungicides at 1000, 2000 and 3000 ppm concentrations and the regression of normalized growth rate were used to determine the EC50. The application of different fungicides on Pestalot...

Humans are exposed to complex mixtures of pesticides and other compounds, mainly via food. Azole fungicides are broad spectrum antifungal compounds used in agriculture and in human and veterinary medicine. The mechanism of antifungal action relies on inhibition of CYP51, resulting in inhibition of fungal cell growth. Known adverse health effects of azole fungicides are mainly linked to CYP inhi...

Isolates of Agaricus bisporus strains F56 and U3 were tested for sensitivity to several selected fungicides in vitro. The analysis showed that flusilasole + carbendazim and cyproconazole + carbendazim were the most toxic fungicides to A. bisporus strain F56 with respective EC50 values of 0.04 and 0.23 mg/l. The least toxic fungicides were carbendazim (EC50 = 16.58 mg/l) and trifloxystrobin (EC5...

Triazole fungicides are used broadly for the control of infectious diseases of both humans and plants. The surge in resistance to triazoles among pathogenic populations is an emergent issue both in agriculture and medicine. The non-rational use of fungicides with site-specific modes of action, such as the triazoles, may increase the risk of antifungal resistance development. In the medical fiel...
