Abstract
CANDELERO, DJ et al. Trichoderma spp. fostering growth on Capsicum chinense Jacq. seedlings and antagonistic against Meloidogyne incognita. Phyton (B. Aires) [online]. 2015, vol.84, n.1, pp.113-119. ISSN 1851-5657.
Fourteen native strains of Trichoderma spp. from wildand agricultural pathosystems in the state of Yucatan, Mexico, with growth-promoting ability of Capsicum chinense Jacq. seedlings were evaluated and antagonistic effect of their filtrate against second-stage juveniles (J2) of Meloidogyne incognita. The strains T05-02 and T27-08 showed the best significant effects on plant hight variable increments 55.57 and 47.62%, theT07-04 with 29.48% more root length, theT02-01 and T07-04 isolates increased from 48.71 to 84.61% in volume radical and 53.40% of total dry biomass. Statistical analysis (p=0.001) of T43 and T43-13-14 filtrates caused 100% mortality at 24 and 48h. In the test of reversibility to 24 h after replacing the filtrates T43-13, T43-14, TH09-06 and TH20-07 by sterile distilled water, the J2 did not recover their viability, so they were considered as the best potential strains of Trichoderma spp. with antagonistic capacity in J2 of M.incognita.
