RESENDE, Maria de Lourdes et al. Corn seed inoculation using Trichoderma harzianum as a growth promoter. Ciênc. agrotec. [online]. 2004, vol.28, n.4, pp.793-798. ISSN 1413-7054.

The objective of this work was to study the effect of the fungus Trichoderma harzianum as a growth promoter on the corn seeds treated with different fungicides. This experiment was carried out in pots in a greenhouse by adopting the experimental completely randomized design in (3 X 2) factorial scheme, by utilizing the treatments with fungicides: Captan®, Maximim® and control and inoculation (with and without an inoculum) with four replicates.  The agronomic characteristics evaluated were: plant height, shoot and root dry matter weight and also the inoculum isolation technique on the rots after sowing.  Significant differences were found only for the factor inoculum in the characteristic root dry matter weight. The results obtained revealed that the fungus Trichoderma harzianum stimulated greatest  dry matter accumulation  in the roots of corn plants and also it was  present in the roots of plants from  inoculated seeds  regardless of the treatment of the seeds with fungicides.
