The loss in seed production often leads to unproductive, weed-dominated pastures in need of resowing. Seed yield reductions of 90 per cent or more have been measured in the highly susceptible varieties, Woogenellup and Yarloop. Management Stock will not graze a collapsed pasture. However, one way of coping with diseased pastures is to graze them heavily throughout the season. Grazing removes much of the affected material and, if continued, may enable new growth to be used before it becomes seriously infected.
Cultivation associated with pasture renovation, and burning are sometimes helpful.
However, some farmers have found this practice to be unpredictable, with the benefits often short lived if the pasture becomes rapidly reinfected. As resistant types replace susceptible varieties, disease control with fungicides will become less important. However, fungicides are still an economic short term control measure in clover-dominant hay and seed crops of susceptible varieties. Spraying benzimidazole fungicides such as Benlate , Bavistin and Spin has produced economic increases in hay yields. All are currently registered for clover scorch control.
