Resumo: | Two experiments were carried out to evaluate the effect of two commercial products, one containing plant-growth promoting rhizobacteria (PGPR) and micorrhizae, and the other containing micronutrients and aminoacids, on the development of irrigated rice. One kilogram of the biological product Biosol (trade mark) was added to the seeds at sowing time (1kg / ha) and the biofertilizer Greensol (trade mark) was sprayed by airplane (200 ml / ha) in association with fungicides, when 5% of panicles had been emitted. The treatments used were T1: Control; T2: Greensol; T3: Biosol + Greensol and T4: Biosol. Five parameters were evaluated: number of shoots per meter, dry weight 90 days after sowing, grain yield, empty grains percentage and incidence of brown spot disease (Helminthosporium oryzae Breda de Haan). Number of shoots per meter was uniform in all treatments. Grouped analysis indicated superiority of all treatments with Biosol over the control for the parameters of dry weight of plants and roots. Treatments T3 and T4 presented superior yields. In these treatments empty grain percentage was lower than the control. Brown spot severity index indicated that all treatments were better than control and T3 and T4 treatments had the lowest disease index. KEY-WORDS: Helminthosporium oryzae; Oryza sativa; disease control; rice. |

Foram conduzidos dois experimentos com o objetivo de avaliar os efeitos de dois produtos comerciais sobre o desenvolvimento da cultura do arroz irrigado e sobre a incidência da mancha-de-grãos causada por Helminthosporium oryzae. Um dos produtos consistia de rizobactérias promotoras de crescimento de plantas (RPCPs) e micorrizas (Biosol) e o outro era constituído por micronutrientes e aminoácidos (Greensol). O produto biológico, Biosol, foi adicionado ao recipiente das sementes no momento do plantio, na dose de 1 kg/ha. O biofertilizante, Greensol, foi aplicado na dose de 200 ml/ha, via pulverização aérea, juntamente com a aplicação de fungicidas, por ocasião da emissão de 5% das panículas. Os tratamentos utilizados foram T1: Controle; T2: Greensol; T3: Biosol + Greensol e T4: Biosol Os parâmetros avaliados foram: número de perfilhos/metro linear e a produção de matéria seca aos 90 dias após a semeadura, a produtividade de grãos, a percentagem de espiguetas vazias e a incidência da mancha-de-grãos (Helminthosporium oryzae Breda de Haan). O número de perfilhos/metro linear não diferiu entre os tratamentos. A análise conjunta dos ensaios indicou que os tratamentos com Biosol foram superiores na produção de massa seca total e radicular, produtividade superior e menor percentual de espiguetas vazias. O índice de severidade da mancha-de-grãos indicou que todos os tratamentos foram melhores que o controle, sendo o T3 e o T4 os que apresentaram menores índices de doença.
