Occurrence of black point disease complex of wheat in eastern Uttar Pradesh
Abstract
Black point disease complex of wheat resulting from different types of field fungi common in different region of eastern Uttar Pradesh due to delayed sowing of farmers, intermittent rain, high relative humidity and relatively rise in temperature during anthesis stage.Therefore, an extensive survey was done in different district of Eastern Uttar Pradesh during 2012-13 to monitor wheat grain samples for black point incidence and severity. Total 26 wheat seed samples tested for knowing the seed infection percentage and range of infection in different district.During the detection maximum black point infection (3.15%) was found in the wheat variety K-9423 of Faizabad produced and minimum average infection (0.13%) was found in the variety HD-2733 of Ghazipur,Azamgarh and Siddarth Nagar produced.
