“…Vegetative filter strip (VFS) is an effective approach used along field edges and water bodies to reduce herbicide runoff from cultivated fields (Otto et al, 2012). VFS allows reducing runoff flux, volume and herbicide concentration in the runoff water by increasing herbicide retention to organic matter and soil sediments.…”

Environmental fate of S-Metolachlor: a review

et al. 2014

View full text Add to dashboard Cite

-S-metolachlor is a preemergent herbicide used for the control of annual grasses and small-seeded broadleaf weeds in more than 70 agricultural crops worldwide. Recently, S-metolachlor has been used to control imidazolinone-resistant red rice in rice-soybean rotation in lowland environments of the Southern Brazil. However, limited information concerning the environmental fate of S-metolachlor in lowland soil is available in the literature. Thus, this review was designed to describe the major transport and dissipation processes of S-metolachlor in attempting to improve weed management programs used in rice-soybean rotation and mitigate environmental contamination of lowland areas.Keywords: chloroacetamide, degradation, dissipation, transport, retention. RESUMO -S-metolachlor é um herbicida pré-emergente utilizado mundialmente para controle de plantas daninhas em mais de 70 culturas agrícolas. Nos últimos anos, esse herbicida vem sendo usado para controlar arroz-vermelho resistente às imidazolinonas em áreas de rotação soja-arroz irrigado, em terras baixas no Sul do Brasil. No entanto, existem poucas informações consistentes sobre a dinâmica ambiental de S-metolachlor em terras baixas. Nesse contexto, esta revisão teve por objetivo descrever os principais processos de transporte e dissipação de S-metolachlor, visando otimizar o manejo de plantas daninhas na rotação soja-arroz irrigado e mitigar a contaminação ambiental de terras baixas.

“…After 21 days (second flood, 29th April) and 65 days (third flood, 12th June), the flooding was repeated with uncontaminated water, and water samples collected at the same sampling points in order to detect herbicides release according to a sponge-like effect (Otto et al, 2012). Metolachlor is about 50-fold more soluble than terbuthylazine (Table 1) according to recent reviews; instead lipophilia (logK OW ) is similar or slightly lower for metolachlor.…”

“…The water purification service is ensured by complex physical, chemical and biological interaction processes performed within the ''plant-soil'' system. Moreover, the water purification ES is of paramount importance, particularly in intensive agricultural landscapes that are seriously contributing to non-point source pollution mainly by soil erosion and surface runoff into water bodies, threatening potable water sources, non-target organisms and aquatic ecosystems (Vianello et al, 2005;Lazzaro et al, 2008;Otto et al, 2012). Numerous studies have confirmed that levels of pesticide concentrations in surface waters are undoubtedly linked to crop and soil management practices deployed within the agricultural basins (Dabrowski et al, 2002;Anderson et al, 2011).…”

“…vegetated filter strips, grassed waterways) and off-site (e.g. riparian and artificial wetlands) mitigation systems have been implemented and studied as management practices in crop production, showing significant performances in reducing pesticide loss (Reichenberger et al, 2007;Otto et al, 2012;Vymazal & Brezinovà, 2015). Specifically, constructed surface flow wetlands (CSFWs) have been tested and used extensively in the last decades, showing that they are effective in water pollution mitigation, by retaining sediments and surface runoff; however, efficiency in pesticide control is highly variable according to the physical-chemical properties of the individual pesticide, soil texture and structure, hydraulic retention time and wetland vegetation.…”

Mitigation of herbicide runoff as an ecosystem service from a constructed surface flow wetland

et al. 2015

Ecosystem services provided by wetland\ud systems presently play a pivotal role in intensive\ud cropland as water purification from agricultural pollution.\ud A field trial was conducted in 2014 to evaluate\ud herbicide runoff reduction and retention using a\ud 0.32 ha constructed surface flow wetland (CSFW) at\ud the outlet of a 6 ha agricultural basin. To simulate an\ud extreme pulse contamination, the CSFW was flooded\ud with a runoff contaminated with metolachlor, and\ud terbuthylazine and two other subsequent floods with\ud pure water were applied 21 and 65 days later. Results\ud show that the CSFW can reduce runoff concentration\ud of metolachlor and terbuthylazine by a factor of 45–80\ud even in extreme flooding conditions. Herbicides\ud retention in the CSFW was reversible, and the second\ud and third floods mobilized 14–31 and 3.5–7.0%\ud respectively, of the amount detected in the first flood.\ud The CSFW performs a high buffer capacity for\ud herbicides, capable to provide water purification\ud service, protecting downstream surface water. Moreover,\ud mitigation capacity of a CSFW for a heavy\ud runoff from a 10 ha basin is 90% for every 50 m in\ud length of a 15 m wide wetland. This confirms that the\ud implementation of CSFWs in agro-systems can\ud improve the sustainability of agricultural production

“…However, the residue of herbicides in the soil can lead to contamination of surface and groundwater (Marchesan et al, 2010;Otto et al, 2012;Santos et al, 2015), besides causing intoxication and harm the growth and development of crops in succession (Artuzi and Contiero, 2006;Dan et al, 2010;Mancuso et al, 2011). This toxicity may or may not be visible and result in reduction of growth, the quality and productivity of the culture, even in the presence of low concentrations of herbicide in the soil (Robinson, 2008).…”

Carryover de herbicidas em sistemas cultivados com olerícolas

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.
