We identified two genes related to fungicide resistance in Fusarium fujikuroi through random mutagenesis. Targeted gene deletions showed that survival factor 1 deletion resulted in higher sensitivity to fungicides, while deletion of the gene encoding F-box/WD-repeat protein increased resistance, suggesting that the genes affect fungicide resistance in different ways.

Muscadine grapes are high in phytochemicals beneficial to humans, such as resveratrol and ellagic acid. Four studies were conducted to explore the relationship between phytochemical content, berry quality, and disease control following full season or early season applications of fungicides. In each study foliar and fruit diseases were lower in the full season treatment compared to the control, ...

The grey mould fungus Botrytis cinerea causes losses of commercially important fruits, vegetables and ornamentals worldwide. Fungicide treatments are effective for disease control, but bear the risk of resistance development. The major resistance mechanism in fungi is target protein modification resulting in reduced drug binding. Multiple drug resistance (MDR) caused by increased efflux activit...

Fungicide application is a key factor in the control of mycotoxin contamination in the harvested wheat grain. However, the practical results are often disappointing. In 2000-2004, 2006-2008 and 2007 and 2008, three experiments were made to test the efficacy of fungicide control on Fusarium Head Blight (FHB) in wheat and to find ways to improve control of the disease and toxin contamination. In ...

Fungicide-resistant Alternaria alternata impede the practical control of the Alternaria diseases in crop fields. This study aimed to investigate cytological fungicide resistance mechanisms of A. alternata against dicarboximide fungicide iprodione. A. alternata isolated from cactus brown spot was cultured on potato-dextrose agar (PDA) with or without iprodione, and the fungal cultures with diffe...

this study was conducted to investigate the effects of planting date, foliar application of benomyl fungicide and potassium silicate in improving the quality of soybean (cv. williams) seed in gorgan during 2011 and 2012. in the first year (2011), the experimental treatments were including planting dates (april 20, may 13, june 3, june 29 and july 22) and foliar application of benomyl fungicide ...

in conventional agricultural systems application of fungicide and pesticides for seed treatment had been extended in wide range. this study was conducted to evaluate the effects of seed treatment on seed vigor indices on back cross roshan of wheat cultivar in vitro status during 2007. the experiment was done in a completely randomized factorial design with eight replications. treatment were inc...

There are a number of turf fungicides the activity of which is based on the phosphite (=phosphonate) ion (P03-). Chipco Signature fungicide (active ingredient fosetyl-Al) is the most common, and has become a "keystone" product for disease control programs on many golf courses across the country. This is in part because of the general enhancement in quality on stressed turfgrass that has been re...

The effect of fungicides on silkworm larvae was analyzed with regard to the fact that these beneficial insects are usually affected by fungicides, Daily feeding on 1 and 2g/liter of carbendazim, a systemic fungicide, did not have significant effects on larval and pupal mortality. However the weight of the treated larvae showed considerable weight decrease up to 37% weight.. All the economic tra...
