However, it's productivity is very low in our country due to number of biotic and abiotic stresses. Globally, variety of biotic stress (Insect-pest, fungi, bacteria, viruses, nematodes etc) adversely affects its production and productivity. Among phytoparasitic nematodes, cereal cyst nematode, H. avenae on wheat is being most important and widely distributed in wheat growing areas of the country. It is causing great losses directly as well as indirectly. Looking to the importance of cereal cyst nematode, Heterodera avenae, numbers of attempts have been made to studies on various aspects of H. avenae on wheat but still information on pathogenecity and it's management on wheat is lacking. Therefore, to fill this gap of knowledge, present investigation were conducted to find out threshold level and management of cereal cyst nematode, H. avenae infecting wheat. Pathogenicity trial was conducted by inoculating cysts (0, 2, 4, 8, 12 and 16 cyst/plant) of cereal cyst nematode H. avenae on wheat. Results revealed that plant growth characters gradually increased with the increase in inoculum levels up to 2 cyst per plant and significantly reduced at and above 4 cyst level. The threshold level of cereal cyst nematode, H. avenae was observed 4 cyst per plant on wheat. In another experiment, bio-agent Trichoderma viride at 10.0% w/w as seed treatment found most effective followed by G. fasciculatum at 10.0% w/w and Glomus fasciculatum at 5.0% w/w to enhance plant growth parameters of wheat and to reduced the nematode influence of H. avenae.
