“…The effects of different concentrations of pesticide on microbial growth were observed on media plate by using the filter paper disc technique. This technique also used to test antibiotics resistance of microbes (Bauer et al 1966) and presently used to test the effect of pesticide on microbial growth (Mallik and Tesfai 1983;Martensson 1992). Chlorpyrifos insecticide commercial name Messban 20 % EC was obtained from the market.…”

The current study was intended to isolate and characterize the plant growth-promoting properties and pesticide (chlorpyripfos) tolerance ability of microbial strains for sustainable vegetable productions. Plant growthpromoting microorganism is a group of microbial consortia to improve crop growth and yield by various direct mechanisms, e.g. nitrogen fixation, phosphate solubilization, production of plant growth hormones, ammonia and siderophore, and indirect mechanisms, e.g. production of antibiotic, hydrogen cyanide to help as biocontrolling agent. Totally, 50 microbes were isolated from soils of vegetable field. Out of 50, 14 strains were selected on the basis of morphological, growth biochemically characters (e.g. gram staining, amylase, cellulase, catalase and citrate test) and plant growth-promoting properties. All strains have ability of ammonia production. Out of 14 strains, IESDV2, IESDV3, IESDV4, IESDV11, IESDV12 and IESD28 were found significant increase in production of IAA, ammonia and phosphate solubilization than others. Strains IESDV3 and IESDV11 showed tolerant at 6 ll/ml concentration of chlorpyrifos which is three-time increase concentration of recommended dose (2 ll/ml). Others strains IESDV12, IESDV13 and IESDV28 were also showed resistance or tolerance at different concentrations of pesticide 2, 4, 6 and 20 ll/ml. These strains also showed plant growth-promoting rhizobacteria activities. Therefore, the main result of this study is to screen and identify that three strains (IESDV3, IESDV11, IESDV12 and IESDV28) can be used as effective pesticide-tolerant plant growth-promoting microbial consortia for vegetable production under sustainable agriculture at eastern Uttar Pradesh.

“…The growth, survival and nitrogenase activity results vary according to the herbicide doses applied, the species/strains studied and the experimental conditions (Faizah et al, 1980;Mallik & Tesfai, 1983;Eberbach & Douglas, 1989;Martensson, 1992;Moorman et al, 1992;Mallik & Tesfai, 1985;Moorman, 1986).

“…No caso de rizóbio, o crescimento, a sobrevivência, a nodulação e a atividade da nitrogenase têm sido avaliados em diversos trabalhos, que revelam resultados inconsistentes, e que variam de acordo com as doses aplicadas, espécies/estirpes estudadas e condições experimentais, como em meios artificiais (Faizah et al, 1980;Mallik & Tesfai, 1983;Eberbach & Douglas, 1989;Martensson, 1992;Moorman et al, 1992), ou em solos (Mallik & Tesfai, 1985;Moorman, 1986).

Resumo -Os efeitos do herbicida Roundup, formulado à base de glifosato, foram avaliados sobre três estirpes de Bradyrhizobium elkanii (BR 29, INPA 80A e INPA 553A), e uma de B. japonicum (BR 86), e sobre três espécies de fungos micorrízicos arbusculares (FMA) (Gigaspora margarita, Glomus etunicatum e Scutellospora heterogama), em meios de cultivo com concentrações crescentes do herbicida (0 a 454 µmol L -1 ); foram também avaliados os efeitos sobre a nodulação e micorrização da soja, em casa de vegetação, em solo que recebeu, antes da semeadura, doses do herbicida equivalentes a 1,25 até 10 L ha -1. O Roundup mostrou-se inibitório ao crescimento de Bradyrhizobium spp. e aos fungos em meio de cultura, e esse efeito foi crescente com o aumento das concentrações aplicadas, tendo variado em razão das espécies ou estirpes avaliadas. No entanto, a inibição in vitro só ocorreu em concentrações muito superiores à dose recomendada para aplicações no campo. As estirpes BR 29, INPA 553A e INPA 80A mostraram-se mais tolerantes ao glifosato, em relação à estirpe BR 86. O efeito do herbicida sobre a germinação e o crescimento dos tubos germinativos dos esporos dos FMA foi diferenciado, tendo sido observada inibição decrescente de G. etunicatum para S. heterogama e G. margarita. A aplicação do herbicida ao solo, antes da semeadura, até a dose equivalente a 10 L ha -1 não influenciou na nodulação e na colonização micorrízica da soja.Termos para indexação: simbiose, fungos micorrízicos, Bradyrhizobium, nodulação. Effects of glyphosate on soybean symbiotic microorganisms, in culture media and in greenhouseAbstract -The effects of the Roundup herbicide on three strains of Bradyrhizobium elkanii (BR 29, INPA 80A and INPA 553A), one of B. japonicum (BR 86), and on three species of arbuscular mycorrhizal fungi (AMF) (Gigaspora margarita, Glomus etunicatum and Scutellospora heterogama), were evaluated in culture media containing increasing concentrations of the herbicide (0-454 µM); evaluations were also made on the effects on nodulation and mycorrhiza colonization of soybean grown in a soil treated with Roundup doses equivalent to 1.25 to 10 L ha -1 before sowing. The herbicide inhibited growth of Bradyrhizobium spp. and AMF in culture medium. These effects were directly related to increasing concentrations, and varied depending on the strain and species evaluated. However, in vitro inhibition occurred only when concentrations were greater than that recommended for use in the field. Strains BR 29, INPA 553A and INPA 80A showed to be more resistant to glyphosate, when compared to BR 86. Herbicide inhibition on germination and growth of AMF spore germ tubes decreased from G. etunicatum to S. heterogama and G. margarita. Soil application of Roundup before sowing up to a dose equivalent to 10 L ha -1 had no effect on nodulation and mycorrhiza colonization of soybean.
