Early blight disease

Induction of acquired resistance activates defense-related genes. Current study aimed to (a) initiate potato acquired resistance to the Early Blight disease caused by Alternaria solani through treating potato plants with low and repetitive doses of 2,4-dichlorophenoxy acetic acid (2,4-D), abscisic acid (AB)

In the current work, A. flavus as an herb endophyte was selected to verify its role as plant growth-promoting and protection such as antimicrobial activity, IAA production, phosphorus solubilization and nutritional improvement of the tomato plant. So far, there is no previous investigation has been done on evaluating the potential of A. flavus as tomato plant growth promotion and to control Alternaria early blight disease of tomato.

Early blight is the most devastating disease of tomato it is caused by pathogens i.e. Alternaria solani. In tropical and subtropical countries it creates hazardous effect. It is also a common problem in United Kingdom, Australia, India, Nepal and United States. It is one of the most common foliar diseases of tomatoes. The disease can occur over a wide range of climatic conditions, but is most prominent in areas with heavy dew, rainfall and high relative humidity. Every year sever disease appears in north India.

Early blight of potato caused by Alternaria alternata is one of the major diseases causing considerable yield loss. Efficacy of bio-agents was studied and revealed the all four Trichoderma species significantly reduced the mycelial growth of the pathogen over the control by dual culture method. Significantly maximum inhibition of mycelial growth was obtained with T. viride (57.08%) followed by T. azospirillum (50.00%), T. harzianum (43.26%) and T. virens (37.08%) of the pathogen after 48 hours of incubation. In present study, T. viride was observed more inhibitory against A. alternata...

Tomato is one of the most extensively cultivated vegetables and is a rich source of nutrients such as vitamins, antioxidants and minerals for a balanced human diet. World over, early blight (EB) caused by Alternaria solani Sorauer is limiting tomato production and causes great losses. In total, 350 tomato genotypes from ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi were evaluated for early blight resistance under epiphytotic conditions at ICARIndian Institute of Vegetable Research (ICAR-IIVR), Varanasi.

Studies were undertaken to evaluate the plant extracts, fungicides and bio-agents against early blight disease of tomato caused by Alternaria solani under in vitro and vivo conditions. Among the four evaluated plant extracts against A. solani, neem leaf extract at 15% (w/v) was found to be most effective in inhibiting the mycelial growth of the pathogen with inhibition of 52.36 per cent, followed by combination of garlic clove and green chilli extract with the inhibition of 50.42 per cent.

Turcicum leaf blight (TLB) or Northern Corn Leaf Blight (NCLB) is a ubiquitous foliar disease of corn (maize) caused by Exserohilum turcicum, the anamorph of the ascomycete Setosphaeria. The TLB fungus survives through the winter on infected maize residue at the soil surface. As temperatures rise in the spring and early summer, the fungus produces spores on residue, and then the spores are splashed or wind-blown onto leaves of the new maize crop. Infection occurs during periods of moderate (64° to 81°F), wet and humid weather.

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.
