“…Herbicide persistence is an important fact in crop production since residues can potentially injure sensitive crops grown in rotation (Riddle et al 2013). A laboratory test helps to predict potential herbicide residue problems so that proper decisions can be taken about crop rotation, herbicide selection, planting date, and other cultural practices.…”

The effects of various concentrations of bensulfuron-methyl residues (BSM, 0-500 µg kg -1 ) on the growth and photosynthesis of soybean and peanut were studied. Shoot length, root length, root-to-shoot ratio, and biomass of soybean and peanut seedlings declined with the increase of BSM residue concentrations. As the concentration of BSM increased, SPAD value, net photosynthetic rate, stomatal limitation, stomatal conductance, and transpiration rate also declined with varying extent, but dark respiration rate and intercellular CO 2 concentration increased gradually. PSII maximum quantum yield, actual quantum yield, and electron transport rate were significantly reduced by the BSM residues in soil, and the reduction was mostly attributed to the decrease in photochemical quenching coefficient. The results showed that photosynthesis in both crops was limited by nonstomatal factors. The residues of BSM caused reversible damage in PSII reaction centers and decrease the proportion of available excitation energy used for photochemistry.Additional key words: Arachis hypogaea; chlorophyll fluorescence; gas exchange; Glycine max (Linn.)

“…Studies on the possible effects of both products in the preemergence of peanuts are scarce. Furthermore, research on the effects of mesotrione indicates that mass and yield of soy in the pre-emergence were not reduced (Riddle et al, 2013a); while beans had total mass and yield reduced (Felix et al, 2007;Riddle et al, 2013b). Some studies show the application of clomazone in the pre-emergence of 'Jalo Precoce' beans (Fernandes et al, 2011) and castor beans (cultivars Íris and AL Guarany) (Maciel et al, 2007) was selective to crops.…”

The objective of this study was to analyze the effect of soil fertilization with sulfur-based fertilizers, sulfate and elemental sulfur forms on biomass production, nutrient characteristics of sorghum and soil chemical properties. The experiment was carried out in a 4 x 4 factorial scheme (four sulfur sources: single superphosphate, agricultural gypsum, elemental sulfur powder and elemental sulfur granulated with bentonite, and four sulfur doses: 0, 40, 80, 120 mgdm-3) using four replications in a completely randomized design, being cultivated in pots under greenhouse conditions. The sorghum was cultivated for a period of 51 days after emergence of the seedlings. The shoot dry mass, shoot macronutrients content, root and soil and pH of the soil were evaluated. There were interactions between sources and sulfur doses in the variables such as shoot dry mass, sulfur in the root, sulfur and calcium in the soil. Elemental sulfur (granulate) showed lower concentrations of phosphorus, sulfur and N:S ratio in the shoot. The concentrations of potassium, calcium and magnesium did not show significant differences, both for the shoot and the root. The pH of the soil was reduced depending on the sources and doses of elemental sulfur. The sources and doses of sulfur did not influence the levels of phosphorus, potassium, and magnesium in the soil. The elemental sulfur in the form of powder is the best source of sulfur for forage sorghum cultivated in soil with alkaline pH.

“…Para identificar o efeito residual e o potencial de lixiviação de herbicidas no solo, o método de bioensaio em casa de vegetação é ferramenta simples, rápida e de baixo custo, além de ser sensível para detectar a eficácia e a fitotoxicidade dos herbicidas (Riddle et al, 2013). Neste contexto, Inoue et al (2012) verificaram que o bioindicador Cucumis sativus foi mais sensível aos herbicidas hexazinone, diuron, diuron + hexazinone e diuron + hexazinone + sulfometuron-methyl.…”

PALAVRAS-CHAVE Bioensaio Comportamento no solo Precipitação pluviométrica KEYWORDS Bioassay Behavior in soil Rainfall RESUMO:A eficiência no controle de plantas daninhas e o destino de herbicidas no ambiente são influenciados por processos de lixiviação e efeito residual. Diante do exposto, objetivou-se avaliar o potencial de lixiviação e o efeito residual de diuron + hexazinone + sulfometuron-methyl em amostras de solos argiloso e arenoso. Para verificar o potencial de lixiviação, foram aplicados 1,14 + 0,32 + 0,02 e 1,50 + 0,42 + 0,03 kg ha -1 nos solos arenoso e argiloso, respectivamente, em colunas, observando-se o controle de Cucumis sativus nas profundidades de 0-5, 5-10, 10-15, 15-20, 20-25 e 25-30 cm, com simulação de seis precipitações (0, 20, 40, 60, 80 e 100 mm). Na avaliação do efeito residual, foi adotado o esquema fatorial de 2 × 7 + 1, em que avaliaram-se as doses de 1,14 + 0,32 + 0,02 e 1,50 + 0,42 + 0,03 kg ha -1 em ambos os solos, com sete épocas de aplicação (zero, 20, 40, 60, 80, 100 e 120 dias, entre a aplicação e a semeadura do bioindicador), além do controle sem a aplicação. Através de modelo log-logístico não linear, encontrou-se o t 1/2 da mistura formulada. Nas simulações de precipitações superiores a 60 mm, foram observados controles do bioindicador superiores a 90%, em todas as profundidades, em solo arenoso. No solo argiloso, verificou-se a presença da mistura formulada entre 0-15 cm, nas maiores simulações. Houve interação significativa, no efeito residual, entre as doses no solo argiloso com t 1/2 de 100 e 80 dias para a maior e a menor dose, respectivamente. Para o solo arenoso, a interação não foi significativa, com t 1/2 igual a 52 dias. 0-5, 5-10, 10-15, 15-20, 20-25, and 25-30 cm with six precipitation simulations (0, 20, 40, 60, 80, and 100 mm). A 2 x 7 + 1 factorial design was adopted to assess the residual effect, where the doses of 1.14 + 0.32 + 0.02 and 1.50 + 0.42 + 0.03 kg ha -1 were evaluated in both soils, with seven application times (0, 20, 40, 60, 80, 100, and 120 ABSTRACT: Weed control efficiency and herbicide allocation in the environment
