Description
The total white ears is one of the major diseases of forage grasses grown for seeds. Heavy losses are common in fescue species and in Poa pratensis L. While non-parasital factors can be neglected as a cause of the white ears, the tarsonemid mites, especially the species Siteroptes graminum (Reuter) and Steneotarsonemus spirifex (Marchal), are major animal pests. Limiting the period of use of such seed grass stands to a maximum of 2 years and the application of lindane and oleo-parathion preparations have proved effective control measures.
