Bacillus subtilis for root knot nematode in tomato
Answers
The objective of this research was to evaluate the Bacillus subtilis (PRBS-1) effect as growth promoter and suppressor agent of root-knot nematode (Meloidogyne spp.) in tomato cultivation. The treatments consisted in the application of B. subtilis formulation and of the nematicide carbofuran. The plants were maintained in greenhouse during 85 days, when the plants were colleted. Roots were separated from aerial part of the plants to evaluate the treatments effect. The fresh matter production by the aerial part increased either by the chemical or by the biological treatments. The fresh matter of the roots was reduced with application B. subtilis. The effect of the biological treatment on the nematode reproduction was more evident by the reduction of egg masses in the root. The present study indicates that the strain PRBS-1 of B. subtilis promotes tomato plant growth and reduces knoot-root nematode reproduction in tomato roots under greenhouse conditions.
