The causes and risk factors for non-celiac gluten sensitivity are unclear and are being researched. Crop residue left on the surface of the field will increase to some extent the diseases caused by Fusarium species. The analysis demonstrates that predictions are uncertain and future disease risk trends must be differentiated on a geographic and time scale. The disease is often accountable for very serious losses in the field, due to destruction of the foliage, fol­lowed in some cases by sterility of spikelets or in the production of badly shrivelled grain.

Lesions may have a yellow margin, but the degree of yellowing varies among varieties. Although this disease has occurred predominantly in the western part of the state, it has caused damage in the south central and eastern parts as well. sorokiniana) showed much stronger pathogenicity toward wheat than endophytic B. sorokiniana from Pogostemon cablin (P-B. Lesions may have a yellow margin, but the degree of yellowing varies among varieties. This rust disease occurs wherever wheat, barley and other cereal crops are grown. 9.1 Causes of cereal diseases Cereal diseases are caused by fungi, viruses, bacteria and nematodes. Wheat blast is a fungal disease of wheat which is caused by a host-specialized ascomycete Magnaporthe oryzae Triticum (MoT) pathotype (Anamorph Pyricularia oryzae Triticum).It was first discovered in Paraná state of Brazil in 1985 and then gradually spread in wheat growing areas in several countries in Brazil, Bolivia, Paraguay and Argentina. Leaf rust, also known as brown rust, is caused by the fungus Puccinia triticina. The odor is caused by the production of trimethylamine by the fungus. Dihne, H. W. and Oerke. Tundu disease is also called as yellow ear rot diseases. of Agriculture, 1920 1946 Nov;33(4):446-9. The dark, reproductive structures produced by the fungus are key diagnostic features and can often be seen without magnification. Tundu Disease Cycle: (i) Perennation: Since both ‘ear cockle’ and ‘tundu disease’ occur on wheat frequently in association, the bacteria are carried along with the galls developed due to ear cockle disease caused by the nematode. » A symptom of plant disease is a visible effect of disease on the plant. Outbreaks caused by fungal diseases have increased in frequency and are a recurrent threat to global food security [].One example is blast, a fungal disease of rice, wheat, and other grasses, that can destroy enough food supply to sustain millions of people [1–3].Until the 1980s, the blast disease was not known to affect wheat, a main staple crop critical to ensuring global food security.
