“…The variables first productive branch height and plant height, assessed at 132 DAS ( Figures 3A and B), were affected with increasing sulfentrazone doses. Other studies also have reported a lower plant growth in response to sulfentrazone (Main et al, 2004;Pekarek et al, 2010).…”

“…Other authors have verified the residual activity of sulfentrazone affecting cotton plants, which suggests the crop sensitivity to the herbicide. Pekarek et al (2010) observed an 18% intoxication for cotton at 352 DAA (28 days after crop emergence) at a dose of 210 g ha -1 of sulfentrazone applied in pre-emergence in the soybean crop (loamy sand textured soil, 0.32% of OM, and pH of 5.6). In addition, the symptoms worsened at higher doses.…”

“…Weed interference can significantly affect their yield, which requires the use of effective measures to control invasive species. Although soybean-cotton succession is advantageous for producers, weed management adopted in the previous crop may reflect directly on cotton crop planted in succession, especially if the herbicide is not selective to cotton (Pekarek et al, 2010).…”

Residual Activity of Sulfentrazone Applied to Soybean on Cotton Crop in Succession

Weed resistance to glyphosate in agricultural production systems has led to the need of applying herbicides with different mechanisms of action. However, the persistence of these herbicides in the soil can harm the subsequent crop. This study aimed to assess the effect of the residual activity of the herbicide sulfentrazone applied in pre-emergence of soybean on cotton in succession. The experimental design was a randomized block design with five replications, with seven doses of sulfentrazone (0, 37.5, 75, 150, 300, 600, and 1,200 g ha -1 ). Cotton was sown at 112 days after herbicide application (DAA), with an accumulated precipitation of 637 mm during soybean cycle. Variables related to photosynthetic characteristics, phytointoxication, establishment, development, production components, and yield were assessed in both crops. The residual activity of sulfentrazone did not significantly interfere with the assessed variables in soybean but caused significant losses to cotton, which the recommended dosage (600 g ha -1 ) of the herbicide reduced cotton yield by 30%.

“…Crop rotation is commonly performed in the production areas and it presents numerous advantages. However, the use of herbicides with long residual effect on the previous crops can impair growth and development of sensitive vegetables crops in succession (Mancuso et al, 2011), given the sensitivity of plants to these products and their residues in the soil Pekarek et al, 2010;Robinson and Macnaughton, 2012). Thus, to minimize such problems it is important to monitor the inserted areas in rotation systems with vegetables and to use strategies and knowledge in an attempt to reduce the residual effect of herbicides in those areas.…”

Carryover de herbicidas em sistemas cultivados com olerícolas

et al. 2016

O efeito residual de herbicidas no solo sobre culturas sucessoras sensíveis é conhecido como carryover. A maioria dos estudos sobre carryover em olerícolas tem sido desenvolvida em outros países, no entanto, os problemas advindos desse fenômeno são uma realidade também no Brasil. A limitada informação presente na literatura, aliada à ausência de alertas e períodos de restrição nas bulas dos herbicidas comercializados no país para o cultivo de olerícolas sensíveis em sucessão contribuem para a ocorrência de grandes prejuízos aos olericultores. Carryover de herbicidas pode causar intoxicação de forma visível ou não nas olerícolas, reduzir o crescimento e a produtividade, assim como comprometer a qualidade do produto e até mesmo inviabilizar a área para o cultivo por anos. A presente revisão descreve a dinâmica dos herbicidas no solo e reúne diversos trabalhos acerca do efeito residual de herbicidas em olerícolas. Além disso, discute as possíveis formas de monitoramento das áreas cultivadas, através da análise em laboratórios ou de bioensaios, e as estratégias para minimizar os efeitos danosos nessas culturas, que são altamente sensíveis. Nesse contexto, o manejo integrado de plantas daninhas é essencial para redução da necessidade de utilização de herbicidas e aporte desses no solo, diminuindo os riscos de carryover, além de medida legislativa para inclusão dos períodos de restrição de cultivo de olerícolas sensíveis nas bulas dos herbicidas.

“…Because of slow sulfentrazone dissipation in some soils especially under conditions of drought and cool weather, a potential risk of carry-over to rotational crops is of concern. Injury to cotton (Gossypium hirsutum L.) (Ohmes et al 2000;Main et al 2004;Pekarek et al 2010), sugar beet, and sorghum (Sorghum bicolor L.) (FMC Corporation 1999) has been reported one year after sulfentrazone application, and consequently extended recropping intervals are advised for these crops. In western Canada, lentil has exhibited sensitivity to sulfentrazone residues (Johnson E.N.…”
