The chickpea (Cicer arietinum L.) is an important crop in the world. In this study, six
strains of indigenous rhizosphere microorganisms (T442, T3241, 7A1, 751, HRG- 050 y HRG-060) were characterized
morphologically and biochemically through catalogs and API tests, and evaluated
as growth promoters and biocontrol agents of F. oxysporum f. sp. ciceris (Foc), causal agent of Fusarium wilt of chickpea under laboratory and
field conditions. Preliminary studies were performed in vitro, evaluating antagonism
by PICR of Foc, in Petri dishes with PDA
culture medium; the stimulation of germination was evaluated by seed inoculation
with the same strains. In the field, chickpea seeds were inoculated with said antagonistic
strains at a concentration of 1 ¡Á 108 ufc or conidia mL©1, establishing eight treatments: six based on the
inoculation of seed with each antagonist strain, a chemical treatment (Benomyl)
and a witness, in block design randomized complete, evaluating the protective effect
and stimulatory in chickpea plants. The strains were characterized as Bacillus subtilis, Agrobacterium radiobacter, Pseudomonas sp., Trichoderma sp., and Bacillus megaterium, the latter with low percentage
of identification. HRG-060 (Trichoderma sp.) and T442 (Bacillus subtilis) proved to be the best biocontrol
agents in laboratory and field, as well as higher growth promoters, as significantly
reduced growth of the pathogen and the incidence of the disease in the field, and
increased the germination, greenness, biomass and yield of chickpea. The use of
strains HRG-060 y T442 to control Fusarium wilt of chickpea may be possible in the
conditions that have the central area of Sinaloa.
