Throught many years of research on apple rust in loess plateau of east Gansu,it was found that cupressaceae plants was the apple alternate parasitic object of apple rust,Sabina chinesis was one of them.Teliospore of apple rust were not all germinated within first years,individual gall was germinsted in the second year.The farthest effective propagation distance of apple rust can reach 10km,it was more than usual distance of 3 ~ 5km.In the variety predication methods,cypress flowering was accurate and effective method on forecasting the apple rust.We should take positive control measures in apple orchard,meanwhile cupressaceae plants were also major control objects.
