The development of satisfactory measures for the control of the dwarf bunt disease in winter wheat is complicated by the long persistence of the causal fungus in the soil and also by the occurrence of physiologic races. A brief review of literature dealing with these problems is presented.The present paper deals primarily with the use of fungicidal chemicals in the control of this disease. Experimental results from tests conducted during the period 1954–1958 showed that chemical seed treatment was useless against soil-borne inoculum, but that liquid mercurial and chlorobenzene seed dressings were highly effective against seed-borne spores. The only substantial reduction of disease in the field was achieved by the use of chlorobenzene fungicides applied to the surface of the soil shortly after planting.A list of recommendations for seed treatment, as a measure of limiting the spread of this disease, is given at the end of this paper.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.

Abstract A description is provided for Tilletia controversa. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Aegilops, Agropyron, Alopecurus, Arrhenatherum, Beckmannia, Bromus, Dactylis, Elymus, Festuca, Holcus, Hordeum, Koehleria, Lolium, Poa, Secale, Triticum, Trisetum. DISEASE: Causes dwarf bunt of winter wheat, and occurs sporadically on many grasses. Occasionally infects winter barley. Infected plants develop chlorotic flecks at an early stage, are markedly stunted, and produce rather fat, persistently green ears with protuberant spikes caused by the bunt balls which fill the grain. As with T. caries (CMI Descriptions No. 719) and T. foetida (CMI Descriptions No. 720) the contents of the grain are converted to a mass of teliospores which constitute the bunt ball. GEOGRAPHICAL DISTRIBUTION: Europe (except Spain and UK); N. Africa, W. Asia, N. America, Argentina and Uruguay (CMI Map 297, ed. 2, 1968). TRANSMISSION: Teliospores are released when the grain is harvested and contaminate soil and seed. Soil-borne spores are the major source of inoculum for infecting crops which occurs between December and April in NW USA (43, 1295). Teliospores in bunt balls can remain viable in the soil for several years.
