EAR-COCKLE AND YELLOW EAR-ROT DISEASES OF WHEAT: II. 6. Yield loses up to 70% have been reported, ranging from 30-70%. No ear-cockle or fundu was observed to the extent of 103 larvae per 1000 g soil. The wheat seed gall nematode is an economically important pest of wheat (Triticum sp.) Currently in north Africa and west Asia only. It causes a disease in wheat and rye called "ear-cockle" or seed gall. Symptoms: Leaves become rolled, wrinkled, turn yellow and die. Ear cockle disease (Anguina tritici (Steinbuch) Filipjev) of wheat in Rajasthan, India. Development of ear-cockle and fundu diseases of wheat was found to be dependent on larval and bacterial concentrations, temperature, humidity, age of seedlings and depth of placement of the galls. Sometimes, a bacterium corynebacterium tritici is also associated with nematode, therefore the disease also named as yellowing rot. Chatrath et al. Causal organism: It is caused by the nematode Angullulina tritici. Singh D. Agrawal K. ( 1987 ). al. Seed Science and Technology 15 777 - 784 . The grains for sowing purposes should be thrashed from uninfected wheat ears. The nematode larvae feed ecto-parasitically around the growing point of the plant.

NEMATODE BACTERIAL ASSOCIATION BY PRAMILA GUPTA*) and GOPAL SWARUP Division of Nematology, Indian Agricultural Research Institute, New Delhi 12, India The pathogenicity on wheat of the nematode Anguina tritici, alone and in combination with the bacterium Corynebacterium tritici, was studied. The infected plants show increased tillering and produce ears earlier than the healthy plants. The number of wheat ears per unit area, which is an indication of the plant population, can be obtained by manual, semi-automated and rye (Secale cereal L.), causing a disease called ‘ear-cockle’ or seed gall, that has destroyed 30-70% of the wheat crop in undeveloped parts of the world (Clark et. Ear cockle and yellow ear rot diseases of wheat 1. A sample 3D point cloud acquired over a wheat plot. The random spacing between plants, irregular orientation of the ears and noisy air returns make individual ear detection a challenge. Use of systemic fungicides: The use of fungicides, which till recently was considered impraticable to control the seed borne loose smut disease of wheat, has received much attention. ], was described as a species from India by Prasada and Prabhu (1962).Their description is also available in Anahosur (1978), but Simmons (1981; 2007) provides a more detailed description based on Prasada and Prabhu’s type and cultures derived from it. Threshold of 10,000 juveniles/kg soil develop disease. Abstract. Originally found in many parts of the world but has been eradicated from the western hemisphere.
