A study on nematodes of the species Aphelenchus avenae Bastian, 1865.

In recent years agricultural scientists have become aware of the fact that plant parasitic nematodes have been a serious world problem by depriving farmers of higher yields and greater returns from their crops. It is impossible to assess their economic importance even roughly, for in many parts of the world they have still to be sought, but it is probably safe to say that every country or every crop is troubled by nematodes. Nematodes of the species ‘Aphelenchus avenae’ Bastian, 1865 are of widespread occurrence in soil and in dead or dying plant parts that have been in or on the soil, yet their significance in relation to plant diseases and their role in the soil community remains uncertain
