Thus Coons (phytopath. 8: 70. I918 and PI. Dis. 3ul. Suppl. 15: 121. 1921) has r.^ported that 'vinter killing of wheat results in a reduction of loose sr;.ut on account of the gr.;ato'r susceptibility of infected plants to freezing injury. Fromrne (jhytopath. 10: 53* 1920) has observed that percentages of loose smut are higher in soils of l^v; fertility. Again collabora- tors in the states on the Pacific Coast have c=^lled attention several tines to the fact that loose smut is of minor importance in that region, giving as a reason the dry v/cather conditions that prevail at flowering time. Recent studies with wheat ;jties are showing that tiicre is a wide difference in the susceptibility of various v/heats to loose smut. It has been pointed out (Pl. Dis.
