“…---A great deal of research has been conducted on the adsorption, degradation, and leaching of BSM in soils and its photolysis on soil surface (Saeki and Toyota 2004, Si et al 2004, Zhu et al 2005, Luo et al 2008, Lin et al 2010, Lin et al 2012, including the residual phytotoxicity of sulfonylureas to rotation crops, such as maize, sunflower, sugar beet, and dry beans (Anderson andHumburg 1987, Curran et al 1991). Zhang et al (2016) reported that residual BSM mainly affected plant height, leaf width, and the activity of amylase and peroxidase, but had little effect on the physiological activity in tobacco.…”

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.)

“…Although we could not collect soil samples on August 16 when the highest N 2 O emissions occurred and the cumulative N 2 O emissions for the entire rice season largely depended on this peak, we are still able to draw the conclusion that the application of BSM primarily affected soil nitrification and denitrification processes and hence reduced peak N 2 O emissions. Some reports have indicated that the diversity in the soil microbial community changes with additional BSM or BC (Lin et al, 2008(Lin et al, , 2012Chen et al, 2009). There may be certain related microbial populations that affect N turnover that are not yet completely understood.…”

“…Many herbicides are currently registered for use in wheat and rice fields in China (Zhang, 2003). For example, acetochlor, tribenuron-methyl, and fenoxaprop-pethyl are usually used in wheat fields (Jablonkai and Hatzios, 1991;Zand et al, 2007;Guo, 2002), and butachlor, bensulfuronmethyl, and their mixtures are typically used in rice fields (Min et al, 2001;Lin et al, 2012;Zhao and Li, 2008). Although these herbicides are widely used in China, their effects on CH 4 and N 2 O fluxes (either alone or in combination with other common herbicides) have not been investigated.…”

“…Properties such as low-toxicity, environmental-friendly, and high-selectivity of the herbicides are desirable (Busi et al, 2013). Bensulfuron-methyl (BSM), which was developed in 1970s, is a herbicide belonging to the sulfonylurea class (Saeki and Toyota, 2004) and used in paddy fields (Lin et al, 2012). The mechanism of BSM-mediated weed killing involves the inhibition of acetolactate synthase (ALS) and the biosynthesis of branched-chain amino acids (Saeki and Toyota, 2004).…”

“…This herbicide shows high-selectivity and also appears harmless to the Poaceae crops such as rice and maize (Saika et al, 2014). However, over-utilization can have negative impact on farming by creating herbicide-resistant weeds (Powles and Yu, 2010; Walsh and Powles, 2014) and damaging sensitive crops such as tomatoes and tobaccos (Lin et al, 2012). …”

Bensulfuron-methyl (BSM) is widely used in paddy soil for weed control. BSM residue in the soil has been known to inhibit the growth of sensitive crop plants. However, it is unknown whether BSM residue can affect the agrosystem in general. In this study, we have found significant effects of BSM on the infestation of Bemisia tabaci, Myzus persicae, and Tobacco mosaic virus (TMV) in Nicotiana tabacum. The soil was treated with BSM before the pest inoculation. The herbicide-treated tobaccos showed resistance to B. tabaci, but this resistance could not be detected until 15-day post-infestation when smaller number of adults B. tabaci appeared. In M. persicae assay, the longevity of all development stages of insects, and the fecundity of insects were not significantly affected when feeding on BSM-treated plants. In TMV assay, the BSM treatment also reduced virus-induced lesions in early infection time. However, the titer of TMV in BSM treated plants increased greatly over time and was over 40-fold higher than the mock-infected control plants after 20 days. Further studies showed that BSM treatment increased both jasmonic acid (JA) and salicylic acid (SA) levels in tobacco, as well as the expression of target genes in the JA and SA signaling pathways, such as NtWIPK, NtPR1a, and NtPAL. NtPR1a and NtPAL were initially suppressed after virus-inoculation, while NtRDR1 and NtRDR6, which play a key role in fighting virus infection, only showed up- or were down-regulated 20 days post virus-inoculation. Taken together, our results suggested that BSM residue in the soil may affect the metabolism of important phytohormones such as JA and SA in sensitive plants and consequently affect the plant immune response against infections such as whitefly, aphids, and viruses.
