Agriculture -- New York (State). 578 Grasses and Leguminous Crops in New York Each year the mycelium follows up in the growing tip of the plant and produces its spores in the leaves and stems. Since the fungus hibernates as mycelium in the seed and pos- sibly as spores on the seed, the only feasible,control measure, so far as is known at present, is the hot-water treat- ment. Experiments indi- cate that the best method is to soak the seed 6 hours in cold water, then dip it in water heated to 52 de- grees C. (126 degrees F.) for 15 minutes, or 54 de- grees C. (129 degrees F.) for 10 minutes. The two conditions absolutely necessary for this treat- ment are that the tem- perature of the water re- main constant and that the time of treatment be exact. More than one or two pecks ought not to be treated at once, so as to avoid too great cooling of the water when the seed is dipped and to allow rapid and ready permea- tion of the seed mass. In this wav all seeds will be treated uniformly. The seed may be placed in a bag and suspended in the hot water, but the bag should be made of loosely woven cloth, like burlap, and the seed should lie loosely in it. During the treatment, the water should be continually stirred and the seed shaken from time to time. Since this process is somewhat laborious and delicate, it is rather. Fig. 620.
