Karnal bunt

Wheat is an important cereal crop grown all over the world. There are many abiotic and biotic stresses which affects the yield of the crop. Out of this, diseases are the principal cause which is responsible for the decrease in yield. Karnal Bunt is the major disease which affects quality of food grain. Black Point is also becoming a serious problem in Punjab. The analysis of 140 grain samples collected from different grain markets of 8 blocks of Tarn Taran district in Punjab was conducted during 2018-2019.

The higher wheat grain production will be needed to meet the demand of ever growing population which can be achieved by increasing the productivity and reducing the losses caused by biotic and abiotic stresses. All the three rusts along with Karnal bunt and loose smut in favorable environments causing significant yield losses in wheat.

Wheat is the most important food crop in India. During 2017-18, India’s harvesting recorded wheat grain production 99.70 mt from 29.58 mha cultivated area. India’s participation in the international wheat trade however is not up to the mark as being a major wheat producer. One of the major constraints in exporting wheat is prevalence of Karnal bunt (KB), internationally quarantined disease in the Indo-gangetic plain, major wheat bowl of the country.

Management of crop diseases by biological control is an alternative and effective approach with minimum deleterious effect on environment and human health for ecosystem stability leading to improvement in crop yields. The present study was undertaken to characterize antagonistic rhizosphere bacteria against phytopathogenic fungi i.e., Neovossia indica and Rhizoctonia solani, which cause Karnal bunt and root rot disease, respectively. Twenty two rhizobacterial isolates out of total 88 isolates obtained from wheat rhizosphere, 25% isolates inhibited the growth of both R. solani and N.

Field experiment was conducted to study the role different weather variables on infection of Karnal bunt (KB) disease in Wheat. For the study eighty four recombinant inbred lines (RILs) of wheat cross, Aldan (resistant) and WH 542 (susceptible) were grown in randomized block design with three replications during season of year 2011-2012 and 2012- 2013. The screening of material was made under artificial conditions in field areas. Inoculum was prepared from 10-12 days old active culture of N. indica. Five spikes of each entry were inoculated with 2 ml of inoculum using hypodermic syringe.
