Late blight, caused by oomycetes pathogen Phytophthora infestans (Mont.) de Bary, is the most devastating potato disease in the world. RB gene from Solanum bulbocastanum has been shown to impart broad spectrum resistance against P. infestans races.

Phytophthora infestans is responsible for late blight, one of the most important potato diseases. Phenazine-1-carboxylic acid (PCA)-producing Pseudomonas fluorescens strain LBUM223 isolated in our laboratory shows biocontrol potential against various plant pathogens. To characterize the effect of LBUM223 on the transcriptome of P. infestans, we conducted an in vitro time-course study. Confrontational assay was performed using P. infestans inoculated alone (control) or with LBUM223, its phzC- isogenic mutant (not producing PCA), or exogenically applied PCA.

A genome-scale metabolic model of potato late blight suggests a photosynthesis suppression mechanism
Phytophthora infestans is a plant pathogen that causes an important plant disease known as late blight in potato plants (Solanum tuberosum) and several other solanaceous hosts. This disease is the main factor affecting potato crop production worldwide. In spite of the importance of the disease, the molecular mechanisms underlying the compatibility between the pathogen and its hosts are still unknown.

Late blight disease (LBD) caused by the pathogen Phytophthora infestans (PI), is the most devastating disease limiting potato (Solanum tuberosum) production globally. Currently, this disease pathogen is re-emerging and appearing in new areas at a very high intensity.

Hence, scheduling timely application of fungicides based on the spore concentrations in plant canopy by obtaining reliable predictive models that allow us to know beforehand the atmosphere spore content in a particular area and the suitable meteorological conditions for occurrence of aerial sporangia, can lead to forecasting the emergence of fungal blight. These allows the utilization of forecasting tools for deliberating the need based and timely application of fungicides and to reduce the cost of cultivation.

An experiment was conducted to evaluate calcium chloride (CaCl2) as inducers in induce resistance against late blight of potato caused by Phytophthora infestans. Two per cent CaCl2 used in 9 treatments for different time durations (1/2h, 1h, 2h, 4h, 6h, 8h, 10h, 12h and 0h) and foliar spray and resulted that CaCl2 have ability to reduce disease severity from 22.65 to 48.00 per cent against 57.00 per cent in case of control.

The tomato crop attacked by early blight, late blight, leaf spots, anthracnose, Dampimg off, buckeye rot, wilts and root rots. Among these Damping off diseases in tomato caused by Rhizoctonia solani is very common to see in nurseries, an increased incidence of blight caused by Rhizoctonia solani was noticed in recent past in major tomato growing areas of Ranga Reddy district of Andhra Pradesh.

Quantitative trait locus (QTL) mapping is a highly effective approach for studying genetically complex forms of plant disease resistance. With QTL mapping, the roles of specific resistance loci can be described, race-specificity of partial resistance genes can be assessed and interactions between resistance genes, plant development and the environment can be analysed (Young, 1996). DNA markers tightly linked to quantitative resistance loci (QRLs) controlling QDR can be used for marker-assisted selection (MAS) to incorporate these valuable traits.

Tomato (Lycopersicon esculentum Mill) is one of the most important vegetable crops of the family Solanaceae. Survey for prevalence and severity of late blight of tomato was conducted in three vegetable growing districts of Kashmir valley viz. Anantnag, Baramulla and Budgam. Maximum disease incidence (10.24%), intensity (3.79%) and infected fruits (4.06%) were observed in district Anantnag, followed by district Budgam with 9.67% disease incidence, 3.14% disease intensity and 3.50% infected fruits and the least disease incidence (09.33%), disease intensity (3.04%) and infected fruits (3.

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

Late blight caused by Phytophthora infestans (Mont.) de Bary has historically been a most serious disease of potatoes worldwide, including India. Due to differences in prevailing weather conditions, its severity varies from region to region. when tuber are planted first fort night of October disease initiated within 59 days, and there after the period for disease initiation decreases.

Among major food crops, potato occupies fourth position following rice, wheat and maize across the globe. There are several factors affecting the crop yield and quality in potato of which disease is one of the most important factors. Potato diseases are caused by fungi resulting in the immense economic loss, posing the threat to food security and sustainable agriculture. Therefore, effective disease management is essential to overcome these risks.

Molecular epidemiology is a science that focuses on the contribution of potential genetic and environmental risk factors, identified at the molecular level, to the etiology, distribution and prevention of disease Molecular epidemiology provides the tools‘ (both laboratory and analytical) that have predictive significance and that epidemiologists can use to better define the etiology of specific diseases, and work towards their control.

Cumin (Cuminum cyminum L.) crop is highly infected by blight disease in late sown conditions, experiments were conducted to identify genotype suitable for late sown condition, two cumin genotypes JC-2000-28 and JC95-102 found to be most prominent genotype for late sown conditions. It was found that there were increases in yield by 64.27 and 44.31 per cent, respectively and reduction in Alterneria blight incidence on different locations under study.
