Resumo: A fitorremediação é uma alternativa para a descontaminação de áreas que receberam intensas aplicações de herbicidas. Determinar o período mínimo que as espécies devem permanecer remediando o solo é fundamental para a otimização das áreas a serem cultivadas sem riscos de carryover. Objetivouse com este trabalho avaliar o tempo de cultivo de Canavalia ensiformis em solos contaminados com o herbicida sulfentrazone, de modo que essa espécie remedie o solo em níveis satisfatórios. O experimento foi instalado em casa de vegetação, utilizando-se vasos de 10 dm 3 ; e conduzido no delineamento em blocos cazualizados, em esquema fatorial (5 x 2), com quatro repetições. Os fatores consistiram de cinco períodos de fitorremediação, ou seja, de tempos de cultivo da fitorremediadora (0, 25, 50, 75 e 100 dias após a semeadura) e dois níveis de sulfentrazone (com herbicida na dose de 400 g ha -1 e sem herbicida). A espécie bioindicadora foi a Pennisetum glaucum, cultivada por 42 DAS. Ao longo desse período foram avaliadas as seguintes variáveis: altura de plantas (cm); toxicidade visual (%), utilizando escala que varia de 0 a 100, para ausência de sintomas e morte da planta, respectivamente; e matéria seca da parte aérea (g). Com 75 dias de cultivo da espécie fitorremediadora, não houve diferença entre o solo que recebeu aplicação de herbicida e aquele sem aplicação para as variáveis toxicidade visual, altura e matéria seca da parte aérea da espécie bioindicadora. A C. ensiformis precisa ser cultivada por um período mínimo de 75 dias para descontaminar à níveis satisfatórios solos com o sulfentrazone.Palavras-chave: Bioensaio. Descontaminação. Fitotoxicidade.

Determining the minimum period that a species should remain for remediation of the soil is critical for the optimisation of areas to be cultivated without the risks of carryover. The aim of this study was to evaluate the cultivation time of Canavalia ensiformis in soil contaminated with the herbicide sulfentrazone, for the species to remediate the soil to satisfactory levels. The experiment was set up in a greenhouse, using 10 dm 3 pots in a randomised block design and a 5 x 2 factorial scheme, with four replications. The factors comprised five periods of phytoremediation, i.e. cultivation times of the green-manure species of phytoremediator (0, 25, 50, 75 and 100 days after sowing -DAS), cultivated both with and without the presence of sulfentrazone (400 g ha -1 ). The species of bio-indicator was Pennisetum glaucum, grown for 42 DAS. During this period the following variables were evaluated: plant height (cm); visual toxicity (%), using a scale from 0 to 100 for the absence of symptoms and death of the plant respectively; and shoot dry matter (g). At 75 days of growth of the phytoremediator species, there was no difference between the soil that received the herbicide application and the soil with no application, f...

“…Herbicides that have a long residual effect on the soil can cause carryover problems, making it infeasible to grow sensitive species in succession, which is the case of sulfentrazone (Artuzi & Contiero, 2006;Dan et al, 2010). Moreover, the permanence of the product in the soil for a long time (Blanco et al, 2010) increases the risks of leaching (Melo et al, 2010a) and contamination of groundwater (Santos et al, 2015).…”

Bacteria that present potential to promote plant growth can bring direct benefits both to the remediating plants and to the soil in the sulfentrazone bioremediation process. In view of this, the objective of this study was to evaluate the inoculation response of bacteria of the genus Pseudomonas in soil contaminated with the herbicide sulfentrazone on the growth of the remediating species jack bean (Canavalia ensiformis) and sunflower (Helianthus annuus). The experiment was conducted in a greenhouse in a completely randomized design with four replicates. For each phytoremediating species, three factors were considered, the first being the presence or absence of inoculation with selected bacterial consortium, the second consisting of cultivation with the same species or with the other species, and the third corresponding to the bioremediation time (25, 45, 65 and 85 days after thinning). The leaf area and the dry matter of roots, stem and leaves were evaluated at the end of each time and for each of the species. In general, both remediating species showed lower growth when cultivated together with a plant of the same species. In most of the evaluations, inoculation provided greater accumulation of leaf area and dry matter of leaves, stem and roots of Canavalia ensiformis and Helianthus annuus, with increases varying from 18 to 55%. The results showed the ability of Pseudomonas spp. isolates to promote the growth of plants cultivated in soil with sulfentrazone.Additional keywords: Canavalia ensiformis; Helianthus annuus; herbicide; plant growth-promoting bacteria. ResumoBactérias que apresentam potencial para promover o crescimento vegetal podem trazer tanto benefícios diretos às plantas remediadoras quanto ao solo no processo de biorremediação do sulfentrazone. Diante disso, objetivou-se avaliar a resposta da inoculação de bactérias do gênero Pseudomonas em solo contaminado com o herbicida sulfentrazone sobre o crescimento das espécies remediadoras feijão-de-porco (Canavalia ensiformis) e girassol (Helianthus annuus). O experimento foi conduzido em casa de vegetação, no delineamento inteiramente casualizado, com quatro repetições. Para cada espécie fitorremediadora, consideraram-se três fatores, sendo o primeiro a presença ou a ausência de inoculação com consórcio bacteriano selecionado; o segundo, o cultivo com a mesma espécie ou com a outra espécie, e o terceiro, o tempo de biorremediação (25; 45; 65 e 85 dias após o desbaste). Avaliaram-se, ao final de cada tempo e para cada uma das espécies, a área foliar e a massa da matéria seca da raiz, do caule e de folhas. De modo geral, ambas as espécies remediadoras apresentaram menor crescimento quando cultivadas juntamente com uma planta da própria espécie. Na maior parte das avaliações, a inoculação proporcionou maior acúmulo de área foliar, massa da matéria seca de folhas, caule e raiz de Canavalia ensiformis e Helianthus annuus, com aumentos variando de 18 a 55%. Os resultados encontrados comprovam a capacidade de promoção de crescimento das plantas cultiv...

“…Dan et al (2010) evaluating the effect of several pre-emergent herbicides (including diclosulam at the dosage of 35 g ha -1 ) on weed control in soybean crop and the subsequent effect on successor crop (sorghum), observed that these class of herbicides showed high persistence in soil (diclosulam up to 87 days) and can cause injuries in subsequent crops.…”

“…This herbicide has excellent pre-emergent activity in soil to control of several dicotyledonous and some monocotyledon weeds, being widely used in the control of plants resistant to ALS inhibitors (Blanco et al, 2010). Dan et al (2010) studying the action of pre-emergent herbicides, verified that the residual activity of sulfentrazone was high, exceeding 200 days, which may cause damage to subsequent crops.…”

-The use of herbicides must be made in a rational way, giving priority to reduce possible adverse effects on subsequent crops. The objective was to evaluate the residual effect of pre-emergent herbicides on growth and initial development as well as the biochemical composition of snap bean seedlings. The experimental design used was the completely randomized, with four replications in factorial scheme 3x4, three snap bean cultivars (Macarrão Favorito, Macarrão Preferido e Macarrão Trepador) and three pre-emergent herbicides, plus a control (without herbicide). Was use the residual doses of pre-emergent herbicides sulfentrazone in 0.3 g ha -1 , diclosulam in the concentrations of 0.126 g ha -1 and imazethapyr in 0.05 g ha -1 . The work was developed in a seeds analyze laboratory with the purpose of minimizing possible adverse effects of the environment. The seeds were sowing on germitest paper moistened with solutions containing the herbicides, with each respective treatment. The following characteristics were evaluated: germination (GER), germination speed index (GSI), seedling length (SL) and seedling dry mass (SDM) and soluble protein content (PROT) in addition to the enzymatic activity of catalase (CAT), peroxidase (PER) and phenylalanine ammonia-lyase (PAL). The phytometric variables SL, SDM, GER and GSI reduced in the presence of herbicides, and for the levels of PROT and enzymatic activity of CAT, PER and PAL there was observed a variation according to the genotype. The sulfentrazone showed up as the product of higher toxicity, as well as the Macarrão Trepador as the genotype with lower tolerance.
