Ear cockle is endemic in International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 03 (2019) A film of moisture must be present when the young wheat plants are developing; otherwise, the very active larval nematodes cannot travel from the soil to the growing point of the seedling. The tested genotypes showed differential reactions to ear-cockle and tundu diseases. Cv. If necessary arrangements are not available for controlling temperature, solar energy can be used to kill nematodes. It is mostly found in some parts of northern India especially the states of Bihar, Jharkhand, eastern U.P. The infected plants show increased tillering and produce ears earlier than the healthy plants. Ear Cockle of Wheat.

In Pakistan 2% loss in yield has been reported from D.G. Grains should be stirred well so that no gall remains in the grains. some wheat cultivars to both ear-cockle (wheat seed gall) and tundu (also known as spike blight or yellow ear rot) infections, and the effect of surface sterilization of nema-tode inocula on the development of ear-cockle disease. Because there is another disease caused by Bacterium tritici, which produces similar symptoms. Annals of Plant Protection Sciences, 10(2):302-307 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.

Attacked grains become small, brown to black hard structures called galls. Wheat bunt (Karnal bunt) and now rice bunt are of the major concern in Punjab, Haryana and adjoining parts of Uttar Pradesh. The disease caused by this nematode is known as ear cockle of wheat as the grains are converted into cockles. The wheat seed gall nematode is an economically important pest of wheat (Triticum sp.) Each female produces hundreds of eggs from which 1st stage larvae soon hatch and each moult to 2nd stage, where they remain in this stage until they are released.
