Abstract:
A disease known as the root, crown, and shoot rot of milo is described and reported as occurring in Kansas, Texas, New Mexico, and possibly California and Oklahoma. The disease cannot be controlled by any of the ordinary methods of cultivation or rotation or by changing the time of planting the crop. Studies on varietal susceptibility in the milo disease nursery at Garden City, Kan., have proved that milo and most milo derivatives are very susceptible. Darso is also highly susceptible. Kafirs, feteritas, and most sorgos are highly resistant to the disease. The sorghum varieties, selections, and crosses on infested soil at Garden City are listed and described as highly susceptible, resistant, immune, or segregating, as the case may be. The disease can be controlled by the use of resistant varieties or resistant strains of susceptible varieties. Resistant strains of Dwarf Yellow milo, Wheatland, and Beaver have been selected and seed may be available in the near future for distribution to farmers.
