“…Microbial biomass was negatively correlated with dosage of herbicides, however no detrimental effects on soil microorganisms were observed when the recommended field application rate was used [ 32 , 33 ]. Similar results were obtained by [ 34 ] and [ 35 ] for chlorsulfuron and rimsulfuron known to be weak acids as indaziflam. Chlorsulfuron and rimsulfuron belong to the group of sulfonylurea herbicide that inhibit the production of brached-chain amino acid by targeting the enzyme acetolactate synthase or acetohydroxy acid synthase present in plants, algae, fungi, bacteria and archaea [ 36 , 37 ].…”

Indaziflam, a broad-spectrum, pre-emergence herbicide was the focus of a field investigation conducted after the identification of sporadic injury symptoms on the pecan trees a few months after the application. The study was conducted in two pecan orchards located in southern New Mexico, USA, and southeastern Arizona, USA. The objectives of this study were to evaluate the occurrence and distribution of indaziflam in the soil profile of areas where pecan trees were injured (impacted) and areas where no injury symptoms were observed (unimpacted), and to determine the relationship between indaziflam concentrations and soil properties in those locations. Soil samples were collected, one year after applications, from six depth representing 0–7, 7–15, 15–30, 30–60, 60–90 and 90–120 cm depth to determine the concentration of indaziflam in impacted and unimpacted areas of the two orchards. Soil samples were analyzed to determine texture, bulk density, organic matter content, cation exchange capacity, pH, nitrate, chloride and calcium concentrations. The detection frequency of indaziflam was higher in Arizona than in New Mexico, likely due to the differences between the tillage practices and sand contents of the orchards. No significant correlations were observed between indaziflam and soil properties, however indaziflam was mostly detected in areas where pecan trees were unimpacted probably as result of greater organic matter content and soil porosity. More research is needed to understand the causes of injury to pecan trees by indaziflam application.

“…Highest decrease in dehydrogenase activity (43.57%) was observed at L-8 (Qadirpur Ran) in soil X in contrast to soil Y ( Figure 5) apparently because of the lethal effect of herbicide residues on soil microorganisms. Radiovojevie et al (2011) reported a 42.7% decrease in dehydrogenase activity due to 3.0 µg g −1 dose of nicosulfuron herbicide. Pampulha and Oliveira (2006) observed 80% reduction in dehydrogenase activity due to a combined mixture of prosulfuron and bromoxynil herbicides.…”

“…So herbicide treatments in laboratory bioassays at 10-and 100-fold higher rates than the recommended have been found to reduce significantly the microbial biomass carbon and increase the activity of protease and ß-glucosidase (Martins et al, 2001;Radivojević et al, 2011).…”

SummAryThe effects of the herbicide nicosulfuron on the abundance of cellulolytic and proteolytic microorganisms, activity of β-glucosidase and protease enzymes, and microbial phosphorus biomass were examined. A laboratory bioassay was set up on two types of agricultural soils differing in physicochemical properties. The following concentrations were tested: 0.3, 0.6, 3.0 and 30.0 mg a.i./kg of soil. Samples were collected 3, 7, 14, 30 and 45 days after treatment with nicosulfuron.The results showed that nicosulfuron significantly reduced the abundance of cellulolytic microorganisms in both soils, as well as microbial biomass phosphorus in sandy loam soil. The herbicide was found to stimulate β-glucosidase and protease activity in both types of soil and microbial biomass phosphorus in loamy soil. Proteolytic microorganisms remained unaffected by nicosulfuron.
