PUERTAS, Ana  e  HIDALGO-DIAZ, L. INFLUENCE OF THE HOST PLANT AND ITS INTERACTION WITH Meloidogyne incognita ON THE EFFECTIVENESS OF Pochonia chlamydosporia var. catenulata. Rev. Protección Veg. [online]. 2007, vol.22, n.2, pp. 104-109. ISSN 2224-4697.

The effect of the host plants and their interaction with Meloidogyne incognita (Kofoid and White) Chitwood on the effectiveness of Pochonia chlamydosporia var. catenulata (Kamyscho ex Barron and Onions) Zare and Gams as a biological control agent of root-knot nematodes was studied in glasshouse conditions. Different plant species from the Cuban Intensive Vegetable Production Systems were used to perform the experience. The growth of the fungus in the rhizosphere differed with the host plant. Among the best host plants of P. chlamydosporia var. catenulata were cabbage, salt-wort and cauliflower, resistant crops to M. incognita. The plants infested by M. incognita showed higher levels of fungus colonization than those healthy, and the kidney bean crop was a good host in the presence of the nematode. The use of these crops into rotation systems, with the application of Pochonia chlamydosporia var. catenulata as biological control agent for the management of M. incognita on Intensive Vegetable Production Systems, was recommended.
