Burmuda grass: an alternate host of rust and smut fungi

No comments :

Durva, the Burmuda  Grass or Cynodon dactylon is an alternate host of a number of rusts and smuts. The disease is principally identified during the onset of rainy season when flowering parts of the plants show black masses. The infection by fungi causing rust and smut on Cynodon dactylon has serious impact on the growth and development of the grass itself and on the crop plants growing in the nearby fields. Secondary infections that occur due to colonization of pathogens on various parts of the plant including leaves, stems and inflorescence lead to the final decay of the plant up to summer. However, the roots of the plant and rhizomes survive inside the soil and cause the growth of new shoots in favourable moist conditions. Though the plant is seed borne as well, most of its propagation in nature occurs through rhizomes. The smut and rust diseases of the grass are mostly seed borne.

Key Words: Durva, Burmuda grass, Cynodon dactylon, smut, rust, decay, rhyzome, inflorescence, moist conditions
