“…Investigation of sorption phenomena of pesticides in soils is of great importance from environmental point of view (Khoury et al 2003). Any soil having different physico-chemical properties affect the sorption, transport and degradation of the soil-applied pesticides.…”

Laboratory study on adsorption-desorption of flubendiamide was conducted in two soil types, varying in their physical and chemical properties, by batch equilibrium method. After 4 h of equilibrium time, adsorption of flubendiamide on soil matrix exhibited moderately low rate of accumulation with 4.52 ± 0.21% in red soil and low rate with 3.55 ± 0.21% in black soil. After amending soils with organic manure, adsorption percentage increased to 6.42 ± 0.21% in red soil and (4.18 ± 0.21%) in black soil indicating that amendment significantly increased sorption. Variation in sorption affinities of the soils as indicated by distribution coefficient (K d) for sorption was in the range of 2.98-4.32, 4.91-6.64, 1.04-1.45 and 1.92-2.81 ml/g for red soil, organic manure-treated red soil, black soil and organic manure-treated black soil, respectively. Desorption was slightly slower than adsorption indicating a hysteresis effect having hysteresis coefficient ranges between 0.023 and 0.149 in two test soils. The adsorption data for the insecticide fitted well the Freundlich equation. Results revealed that adsorption-desorption was influenced by soil types and showed that the maximum sorption and minimum desorption of the insecticide was observed in soils with higher organic carbon and clay content. It can be inferred that crystal lattice of the clay soil plays a significant role in flubendiamide adsorption and desorption. Adsorption was lower at acidic pH and gradually increased towards alkaline pH. As this insecticide is poorly sorbed in the two Indian soil types, there may be a possibility of their leaching to lower soil profiles.

“…According to Khoury et al [6], since soil is a complex system, degradation of herbicides is affected by many factors such as temperature, pH, humidity, differences in plowing methods, and type of crop. According to many researchers, while the pH of the soil, speed and time of pesticide application, and content of organic substances are the main parameters in laboratory-scale studies, the humidity and temperature of the soil are the main factors that affect pesticide degradation on the field [7].…”

Aclonifen was used as the most preferable type of herbicide which is used in sunflower farming in the Thrace Region. Bacteria and fungi were isolated from the soil samples taken from the Thrace Region, and a mixed culture was prepared from equal volumes (10 8 CFU/mL) of liquid cultures of microorganisms. Including the witness sample, five different setups were prepared, to which Aclonifen, with a concentration of 1900 g/L, was added. Each unit was diluted with distilled water for six weeks. The water filtered at this stage was measured for chemical oxygen demand (COD), biochemical oxygen demand, total organic carbon (TOC), and Aclonifen. Additionally, pH and dissolved oxygen measurement was performed. According to the results of the study, the highest bioremediation was observed in the soil sample to which 10 mL of mixed culture of microorganisms was added and Aclonifen, COD, BOD 5 , and TOC remediation was observed as 93.2%, 97.8%, 98.8%, and 98.7%, respectively.

“…Coarse-to medium-textured soils with a lower OM content (less than 3%) are less likely to retain herbicides and to cause carryover problems. Under certain circumstances, however, herbicide carryover can occur in any type of soil (Beulke et al, 2000;Cumming et al, 2002;Khoury et al, 2003).…”

A bioassay technique to study clomazone residues in sandy loam soil

et al. 2013

SUMMARYA bioassay test was conducted to evaluate the sensitivity of maize, sunflower and barley to clomazone residues in sandy loam soil. Clomazone was applied at different rates from 0. 12 to 12 mg a.i./kg of soil. The parameters measured 14 days after treatment were: shoot height, fresh and dry weight, and content of pigments (carotenoids, chlorophyll a and chlorophyll b). The results showed that the lowest clomazone concentration caused a significant reduction in all measured parameters for barley and sunflower shoots. Fresh weight of maize shoots was not sensitive to clomazone residual activity in soil while the other parameters were highly inhibited.Nomenclature: clomazone (2-(2-chlorbenzyl)-4,4-dimethyl-1,2-oxazolidin-3-one), maize (Zea mays L.), sunflower (Helianthus annuus L.), barley (Hordeum vulgare L.)
