“…In greenhouse studies with soybeans, pendimethalin has been found to decrease nodulation (3,8,9), inhibit lateral root formation (8), and injure stem tissue (19). Pendimethalin increases shoot weight and nodulation in other leguminous plants (18).…”

Five runner peanut (Arachis hypogaeaL.) cultivars were treated With.f~ur dinitroaniline herbicide treatments or a postemergence herbicide treatment to determine the effect on pod yield and grade, p~rcen~age sound mature kernels + sound splits (SMK+SS). No yield differences due to the dinitroaniline herbicide treatments were noted in the three year study. Southern Runner and GK-7 were higher in yield in one of the three test years, however, no cultivar yield differences were noted in the other two years. Grades were lowerwith pendimethalin in the three years;grades oftrifluralin, ethalfluralin and benefin-treatedpeanuts were variable from year to year.

“…The effect on nodulation was herbicidedependent (Bollich et al 1988;Schnelle & Hensley 1990;Gonzalez et al 1999;Abd-Alla et al 2000) and greatly influenced by the time of application. Smaller reductions in photosynthesis and ARA in sequential metribuzin treatments (T 6 ÀT 13 ) compared to pre-emergence metribuzin (T 4 and T 5 ) and pendimethalin (T 3 ) indicated that soybean plants were under internal stresses.…”

Post-emergence treatments are often the keys to efficient weed control, and could be a substitute or supplementary to preemergence treatment. Accordingly, this study was designed to test the selectivity and efficacy of sequential (pre-C postemergence) applications of metribuzin on weeds in soybean, and to optimize the dose, volume rate and time of application. We observed that sequential metribuzin treatments were more toxic to soil micro-organisms and caused greater inhibition in photosynthesis, acetylene reduction activity and nodulation of soybean compared to only pre-emergence applications of metribuzin or pendimethalin. The negative effects, however, were mitigated by increased activities of superoxide dismutase and ascorbate peroxidase in soybean. The sequential applications left negligible residues at harvest. A sequential application of metribuzin 0.25 kg ha ¡1 2 days after sowing and 0.1 kg ha ¡1 20 days after sowing with 200 Lha ¡1 of water gave a higher seed yield. This ensured the possibility of sequential application of metribuzin with an optimized dose, volume rate and time of application.

“…The use of herbicides may influence nodulation and biological nitrogen fixation in legumes, either by affecting rhizobia, the plant, or both. The herbicides trifluralin, pendimethalin (Bollich et al 1988), and metribuzin (Mallik and Tesfai 1985) have been considered deleterious to the soybean-Bradyrhizobium spp. symbiosis.…”

Soil microbial biomass C and symbiotic processes associated with soybean after sulfentrazone herbicide application

The aim of this work was to evaluate the effects of the herbicide sulfentrazone on soil microbial biomass C and on symbiotic processes associated with soybean (Glycine max (L). Merril). The experiment was conducted in greenhouse using a Red-Yellow Oxisol soil collected from Embrapa Meio Ambiente's experimental field, in Jaguariúna, São Paulo, Brazil and included the following treatments: control, without herbicide and sulfentrazone herbicide application (0.7 mg kg −1 soil) and three harvest periods. The nodule number and nodule dry weight on the onset of soybean development were negatively affected by the presence of the herbicide, as also observed for shoot biomass and shoot total N content. Pod dry weight and pod total N content decreased by 45% in the presence of the herbicide. The percentage of mycorrhizal infection was 50% lower in pots that received sulfentrazone throughout the soybean growing season. Microbial biomass C was lower in the presence of the herbicide only in the initial period of soybean development. Mycorrhizal and rhizobial performance in soybean were reduced by sulfentrazone use, and both possibly contributed to reduced plant growth.
