Field control of facial eczema of sheep
On a sandy soil in a facial eczema-prone district in Northland, New Zealand, facial eczema in sheep was prevented by stocking heavily on irrigated perennial ryegrass (Lolium perenne L.) pasture. Control of the disease was due to two factors, both affecting reduction of dead plant material in pasture: irrigation prevented summer death of ryegrass; hard grazing reduced grass death resulting both from flowering and from shading. Reduction of its substrate prevented the saprophytic fungus Pithomyces chartarum (Berk. & Curt.) M, B. Ellis from developing in sufficient amount to cause facial eczema.Sign-in to see all concepts, it's free!
