Alternaria blight

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.

Tomato is world’s one of the largest growing vegetable crop and ranks first among processing crops. It’s production suffers with many biotic and abiotic factors. Leaf blight disease caused by different species of Alternaria is one of the most dreadful diseases of tomato, causing huge economic losses. The present study was conducted in order to evaluate the efficacy of different fungicides against Alternaria alternata, one of cause for blight disease of tomato.

Carrot (Daucus carota L.) of plant family Apiaceae is a most popular and commonly used vegetable worldwide because of its multiple uses. This crop suffers greatly due to a number of diseases from seedling to maturity stage in which the diseases caused by Alternaria spp. are one of them. Two types of diseases occur in serious farm on this carrot crop, one is the Alternaria leaf (foliar) blight caused by Alternaria dauci and the other one, Alternaria black rot in which two species, Alternaria radicina and A. carotiincultae are involved in the causation of this disease.

Flax (Linum usitatissimum L.) is a food, fiber and oil seed crop cultivated in cooler regions. The oil content of the seed varies from 33–47%. In India it is grown mainly for seed used for extracting oil. The crop is affected by Alternaria blight caused by Alternaria spp. Different doses of microalgae were applied (@ 1.5, 2.5, 3.5, 4.5, 5.5 and 6.5 kg/acre) with irrigation at critical growth stages of crop (vegetative phase, flowering phase and maturity phase) and observations were recorded on plant growth parameters and per cent disease incidence of Alternaria Blight.

The crop is attacked by a number of diseases such as Alternaria leaf blight, Cercospora leaf spot, powdery mildew, downy mildew and anthracnose, amongst which Alternaria leaf blight caused by Alternaria cucumerina is found to cause serious losses throughout Rajasthan and other states. The incidence and severity of Alternaria blight in bottle gourd fields is greatly influenced by temperature, relative humidity, soil condition at the time of planting, splashing rain, wind velocity, leaf wetness and inoculum density available in the soil (Meena et al., 2004).

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.

The yield losses in the range of 48-80 per cent due to early blight (Alternaria solani) damage in tomato were reported from India, Canada, USA and Nigeria (Basu, 1974; Datar and Mayee, 1984; Mathur and Shekhawat, 1986; Sherf and MacNab, 1986; Gwary and Nahunnarao, 1998 and Pandey and Pandey, 2002). The annual economic yield losses due to early blight have been estimated at 79% (Adhikari and Panthee, 2017).

Rapeseed-mustard (Brassica juncea L) is an economically prodigious and utile oilseed crop of the world. Potato dextrose agar media was significantly superior over other tested media at 5 and 7 days after inoculation. However it was at par with mustard leaf dextrose agar at 3 days after inoculation and significantly superior over the rest culture media.

Alternaria helianthi the causal agent of sunflower leaf blight was isolated from a monoconidial culture derived from blight infected sunflower leaves of MSFH-8.Alternariahelianthi was first cultured on PDA and then transferred to Potato Dextrose broth. Toxin was purified from the cultural filtrate by treatment with organic solvents. The identity of the toxin was established by estimating carbohydrate and protein content. Based on the quantity of carbohydrate and protein the toxin was identified as glycoproteinaceous in nature.
