A description is given of a root rot of wheat which is widespread throughout Saskatchewan, where it first attracted attention in and has since become of considerable economic importance; in it was definitely ascertained that oats and barley are also susceptible to this disease in the field.

On wheat the first symptoms usually appear early in June, the outbreak being most marked and. A specific root rot of wheat and other cereals is described which is widespread over Saskatchewan, and occasions severe losses in some seasons.

In early June, the outer leaves of the young plants become discolored, the number of tillers is reduced, growth delayed, and the yield considerably lessened.

An excellent book on baking describes the use of cereal crop species (other than common bread wheat), pseudo cereals, and tuber flours for use in the baking of both yeast and non-yeast breads (Dumke ).

The combination of both gluten and non-gluten ingredients for use in non-traditional breads is near endless. This book will be highly valuable to researchers, students, teachers, farmers, seed growers, traders, and other stakeholders dealing with wheat and barley.

It also advances our knowledge in the field of plant pathology, plant breeding, and plant biotechnology, agronomy, and grain quality and pesticide industries.

Results are presented of lab. and field trials against F. graminearum [Gibberella zeae], F. avenaceum and H. sativum [Cochliobolus sativus]. Seed treatment with niphimycin and griseofulvin reduced root rot by 63 and 60%, respectively, compared with the control. Seed germination was increased.

Results were similar to or slightly better than those with some organo-mercuric compounds. more root rot than the other durums. The potential exists for selection of root-rot resistant durum wheats. One of the most widespread diseases of spring wheat *and barley in North Dakota is the "common root rot” caused by the soil-inhabiting fungus Helminthosporium sativum.

This report covers an investigation of the cereal root-rot complex in California. From cereal fields (primarily wheat and barley) representing 20 counties, the following rootrotting fungi have been isolated: Primary pathogenic fungi: Helminthos porium sativum P., K.

Duveiller, H.J. Dubin. In recent years, Helminthosporium leaf blights (HLB), caused by both Bipolaris so-rokiniana and Pyrenophora tritici-repentis, have emerged as serious concerns for wheat cultivation in the developing world (Duveiller et al., a).This situation arises from several factors.

Bipolaris sorokiniana (teleomorph Cochliobolus sativus) is the causal agent of common root rot, leaf spot disease, seedling blight, head blight, and black point of wheat and fungus is one of the most serious foliar disease constraints for both crops in warmer growing areas.

Dryland root rot. Dryland root rot is caused by Fusarium culmorum (W.G. Smith) Sac., F. graminearum Schwabe and other species (Booth, ; Francis and Burgess, ; Nelson et al., ; Zillinsky, ).

As wheat nears maturity, one may observe the development of scattered white-headed areas consisting of a few tillers to large irregular.

Surveys of wheat fields in West Central Morocco showed average root rot severity indices of and %, and yield losses of 4 and 6% in /86 and /87 seasons respectively.

The most prevalent fungi associated with root rot symptoms were Helminthosporium sativum, Fusarium equiseti, F. culmorum, F. oxysporum, and F. solani. Of these F.

culmorum and H. sativum are recognized as. Because of its wide host range, R. solani AG8 also causes root rot of peas, canola, and many other broadleaf crops in addition to cereals.

On the other hand, canola is also susceptible to R. solani AG and it is this biological species that appears to be a more important cause of Rhizoctonia root rot of canola. The American Phytopathological Society (APS) is the premier scientific society dedicated to high-quality, innovative plant pathology research.

For more than a century, members of APS have been making and sharing significant breakthroughs, both for the science and society.

APS is driven by a distinctive community of scientists, whose energy and commitment ensure the global advancement of this. A study was conducted to determine microsatellite markers associated with resistance in the F7 progeny from a cross between the spot blotch-susceptible Sonalika and resistant G wheat genotypes.

Christensen () wrote a. Root rot disease index in Butula was 17% higher than in the other study sites. Alupe had the lowest root rot disease index of about 48%, while the bean varieties intercropped with maize had significantly lower (P ≤ ) root rot disease index compared to the sole crops in the three study sites.of infected cereal residue.

Sowing break crops on wide or skip rows will reduce the breakdown of cereal residue in the inter-row area. w Reduce moisture stress in your wheat or barley crop through fallow management, avoiding excessively high sowing rates, matching nitrogen fertiliser inputs to available soil water, and controlling in-crop weeds.The Helminthosporium foot-rot of wheat: with observations on the morphology of Helminthosporium and on the occurrence of saltation in the genus.
