Loss Estimation in Wheat Caused by Cereal Cyst Nematode Across Different Agro-Ecological Regions

Avoidable losses caused by cereal cyst nematode, Heterodera avenae on wheat at three different locations (Madar, Nagda and Bujhra) estimated with the application of fluopyram 34.48 % SC at 5ml/kg seed. Results revealed that application of chemical significantly reduced number of females/5 g root, cysts/200 cc soil and larvae/200 cc soil at Bujhra (10.96, 11.73 and 120.16) followed by Madar (13.73, 15.36 and 195.56) and Nagda (17.46, 19.40 and 285.09). Application of chemical significantly increased fodder (84.96, 80.26 and 77.31 q/ha) and grain yield (56.65, 53.51 and 51.54 q/ha) at Bujhra, Madar and Nagda, repectively. Avoidable yield loss in grain yield were recorded at Bujhra (27.05 %), Madar (23.02 %) and Nagda (21.95). Net profit and cost benefit ratio was also determined at Bujhra (Rs. 31372.25 and 1:5.40), Madar (Rs. 24076.00 and 1:4.15) and Nagda (Rs. 21627.75 and 1:3.72).
