This study aimed to compare the efficiency of treatments common bean (Phaseolus vulgaris L.) seeds by using a chemical fungicide (Carbendazim, Derosal), biological fungicides (Agrotich and Biotrichl) and antagonistic microorganisms (Trichoderma spp., Pseudomonas from fluorescent group and Bacillus subtilis) in order to control the fungus Colletotrichum lindemuthianum and their influence in promoting plant growth. For the evaluation of the antagonism in vitro it was used the technique of colony pairing between antagonists and C. lindemuthianum. For the evaluation of the biological fungicides it was used the technique in which the products containing the Trichoderma spp. propagules were put in contact with the C. lindemuthianum at zero and five days after its transfer to the PDA media. The tested doses were 0 g/l-¹ (control Petri dish), 1 g/l-¹, 2 g/l-¹, 3 g/l-¹ and 4 g/l-¹. The evaluation of in vitro antagonism was done by the microbiolization process of the seeds (artificially infected with C. lindemuthianum) with antagonist microorganism as well as with the chemical and biological fungicides. The seeds were sowed in pots containing sterilized soil. Analysis were carried out in the tenth and twentieth D.A.S. of the disease rate, lesions diameter and on the thirtieth D.A.S evaluations of the plants height, dry and fresh mass of aerial part of the rool. The Pseudomonas isolate from fluorescent group presented inhibition percentage of 26,3% to 34,8%. B. subtilis presented 51,3% of the inhibition in the plant pathogen colony growth. The Trichoderma spp. isolate inhibition percentage range from 31,1 % (T. harzianum) to 59,1% (T. koningii). The isolates of Trichoderma spp. and B. subtilis were more promising in the in vitro control of C. lindemuthianum. Under greenhouse conditions, there were no significantly differences between plant growth promotion. T. koningii and Pseudomonas from fluorescent group as well as the biological fungicide Biotrich were able to present diseases rates similar to the standard fungicide Derosal. Other isolates, presented a tendency to decrease the disease, and probably they could be used as chemical fungicide auxiliary to seeds treatment in arder to control diseases.
