In the forest of the Samara region to major diseases of sorghum are striped bacterial blotch, Fusarium root rot and blight. Biological efficiency of chemical system products and Grands Prestige was 22-62 against root rots, bacteriosis 17-40% of bioproduct fitosporin-M and the growth regulator Albite respectively 6-32 and 4-21%. Against Alternaria effectiveness Prestige was 9-22%, fitosporin - 13-34%. By the phase of full ripeness when the intensity of bacteriosis 45-75% of plant height is reduced by 13, their weight - 11, the mass of grains per plant - 28, the number of grains per panicle - 20, the mass of 1000 seeds - 11%. Under the influence of pre-sowing seed treatment chemicals and Prestige Grands increased yield of grain sorghum grain at 4-12, sugar - by 5-9%. In experiments with irrigation at sowing in the average weather conditions for the years 2012-2013. biological grain yield increased in grain sorghum 13-20, sugar - by 28-32%. Important factors of stability of sorghum grain to the fungal infection of the genera Fusarium and Alternaria in the field include the presence on the seeds of the protective film. It may be noted that a significantly higher prevalence of grain grain sorghum, compared with diabetes, due to the fact that the seeds of grain sorghum naked and sweet sorghum filmy. This feature is important to consider in the selection of resistant varieties to this disease.
