The chief method of control is proper rotation of non-susceptible 

 crops, and clean cultivation. For two, or preferably three years, 

 such non-susceptible crops as maize, cowpeas, soy ^beans, millet,' 

 sunflower, tomato, asparagus, cabbage, broccoli, lettuce, caritaloupes 

 and celery should be grown, and should be planted in rows to enable 

 weeds to be kept down. In Oregon an effort is being made to eradicate 

 the pest from strawberry fields by cutting out all diseased plants. No 

 strawberry plants should be distributed from infested beds, owing to 

 the danger of carrying the pest in the soil about the plants.
