Abstract

The peanut root-knot nematode, Meloidogyne arenaria is one of the most damage species of nematodes to peanut crop that cause significant losses. The efficacy of some commercial bio-based formulations of Trichoderma (Biocontrol T34) and Bacillus (Rhizo-N, Phosphoren and Potassiumag) for suppression of M. arenaria on peanut was evaluated under greenhouse conditions. The rates of tested of formulations (2.5, 5 and 10g plant^-1) had a significant (P ≤ 0.05) direct or indirect effect on each of the M. arenaria criteria and parameters of plant capacity for growth and production, compared to untreated control and the nematicide (Fothiazate 10%). Results showed that biocontrol T34 achieved the best significant (P ≤0.05) of nematode reduction at 10g plant-1 (92.881%), with 3.117% increase in plant weight. In exchange for 62.268% in Phosphoren and 7.239% in potassiumag. With percentages decrease in the final population amounted to 3.117%, 7.376% and 33.73% of the nematicide. It could be concluded that the application of commercial bio-based formulations of Trichoderma and Bacillus was useful in suppressing root-knot nematode, M. arenaria, especially when added at the beginning of the growing season.
