Antifungal activity of 2-hydroxy 4,4'6'trimethoxy chalcone individually was tested against spore germination of ten fungi of different genera. Efficacy of the chemical was also tested against conidial germination and other growth parameters of Erysiphe pisi on excised pea leaves. 2-Hydroxy 4,4'6'trimethoxy chalcone inhibited spore germination at all the concentrations. Maximum inhibition was ob...

Many root diseases can cause serious damage to tomato (Solanum lycopersicum L.) production during the seedling growth period, particularly Rhizoctonia solani, Pythium spp., and Alternaria spp. Paclobutrazol (PBZ) has proved reduce of blight disease on seedlings. The present investigation was designated evaluate infected seedlings with R. solani under applications Trichoderma harzianum alone, PB...

Reduced sensitivity to quinone outside inhibitor (QoI) fungicides conferred by the presence of the F129L mutation was identified in Alternaria solani isolates collected in Nebraska in 2000 and in isolates collected from the Midwestern states of Minnesota and North Dakota in 2001. Over 4200 isolates of A. solani collected over a 5-year period from 2002 to 2006 from 11 potato-producing states wer...

This study was investigated the effect of iron NPs and essential oils clove in normal nanoemulsion forms for controlling Fusarium oxysporum, solani, Alternaria solani compared with Azoxystrobin fungicide under laboratory conditions. Data revealed that all tested compounds are capable inhibiting growth mycelial F. oxysporum A. from 0 to 84.4%, 88.9 %, 61.1 respectively. There is relationship fou...

Modern technologies incorporating Geographic Information Systems (GIS), Global Positioning Systems (GPS), remote sensing, and geostatistics provide unique opportunities to advance ecological understanding of pests across a landscape. Increased knowledge of the population dynamics of plant pathogens will promote management strategies, such as site-specific management, and cultural practices mini...

Increasing evidence of fungicide-resistant toxinogenic and pathogenic fungal species is obvious. Looking for new possibilities of antifungal treatment or sources of antifungal substances is a major problem. Some medicinal plants exert strong antifungal properties and could be conveniently used as a promising alternative source for presently problematic antifungal treatment in many areas with re...

This is the first study reporting the evaluation of transgenic lines of tomato harboring rice chitinase (RCG3) gene for resistance to two important fungal pathogens Fusarium oxysporum f. sp. lycopersici (Fol) causing fusarium wilt and Alternaria solani causing early blight (EB). In this study, three transgenic lines TL1, TL2 and TL3 of tomato Solanum lycopersicum Mill. cv. Riogrande genetically...

A novel pathogen- and wound-inducible antifungal protein of 20 kD was purified from tobacco (Nicotiana tabacum) Samsun NN leaves inoculated with tobacco mosaic virus (TMV). The protein, designated CBP20, was purified by chitin-affinity chromatography and gel filtration. In vitro assays demonstrated that CBP20 exhibits antifungal activity toward Trichoderma viride and Fusarium solani by causing ...

Tomato plants are subject to attacks by different types of fungi most which destructive and cause plant death. Extensive researches were carried out attempting find safe easily degradable bio-fungicides with minimum adverse effects. Therefore, naturally originated indigenous products generally considered excellent alternative phytopathogen controlling agents. In recent study we evaluated the an...

Early blight, caused by the fungus Alternaria solani, is a devastating foliar disease of tomatoes, causes massive yield loss each year worldwide. Molecular basis of the compatible host-pathogen interaction was elusive. We adopted next generation sequencing approach to decipher miRNAs and mRNAs that are differentially expressed during Alternaria-stress in tomato. Some of the interesting findings...
