Abstract Competitive adsorption of glyphosate and phosphate on goethite gibbsite illite, montmorillonite two kaolinites differing in surface area was evaluated. The results show that are competing for the sites, but degree competition depends adsorbent. On is very much favour phosphate, closer, still favoured, while kaolinite almost equal. amounts which can be adsorbed also adsorbent: oxides adsorb more than clay silicates. amount dependent specific area. Changes did not affect between...
Bats are an important group of mammals, frequently foraging in farmland and potentially exposed to pesticides. This statement considers whether the current risk assessment performed for birds ground dwelling mammals pesticides is also protective bats. Three main issues were addressed. Firstly, bats toxicologically more or less sensitive than most mammals. Secondly, oral exposure greater lower birds. Thirdly, there other routes relevant A large variation toxicological sensitivity no...
Groundwater monitoring is recommended as a higher-tier option in the regulatory groundwater assessment of plant protection products European Union. However, to date little guidance has been provided on study designs. SETAC EMAG-Pest GW, group regulatory, academic, and industry scientists, was created 2015 establish scientific recommendations for conducting such studies. This report provides GW group’s designs procedures. Because need assess vulnerability leaching both site selection...
The herbicide glyphosate and inorganic phosphate compete for adsorption sites in soil on oxides. This competition may have consequences the transport of both compounds hence contamination groundwater. We present evaluate six simple, kinetic models that only take time concentrations into account. Three were found suitable to describe soil. These three all assumed competitive additive adsorption, but with different equations used adsorption. For oxides, additional assuming also suitable. is...
Abstract Glucosinolates are compounds produced by all cruciferous plants. They can be hydrolyzed to several biologically active and, as such, may serve naturally pesticides. To optimize the pesticidal (biofumigation) effect and assess risk of glucosinolate leaching spread in environment, degradation soil glucosinolates has been studied. The kinetics four glucosinolates, two aliphatic (but‐3‐enyl 2‐hydroxy‐but‐3‐enyl) aromatic (benzyl phenethyl), soils was largely independent specific...
Glucosinolates (GSLs) are produced by plants of the Capparales order. Upon enzymatic hydrolysis GSLs can be transformed to toxic isothiocyanates (ITCs), which used as biofumigants for control soil-borne pests. The rates ITC formation and degradation critical both biofumigation toxicity leaching ITCs in soil. Degradation kinetics benzyl GSL a sandy clayey surface subsoil at 8−9 °C natural moisture contents were investigated, was rate from GSL. followed logistic with t1/2 = 0.7−9.1 days....
The effect of phosphate (ortho-phosphate) on the adsorption widely used glyphosate herbicide was evaluated with three typical Danish agricultural soils as well pure oxides (goethite, FeOOH and gibbsite, Al(OH) 3 ) silicates (illite montmorillonite), which are considered most important adsorbents in soils. Batch experiments where made order to find out how affects adsorbed phosphate. Solution quantified by liquid scintillation counting 14 C-taggered concentration molybdenum blue method. All...
Isothiocyanates of natural origin produced by the hydrolysis plant-produced glucosinolates have potential to control soil pests, but getting sufficiently high isothiocyanate concentrations in is difficult. Furthermore, isothiocyanates proven toxic a wide range organisms and hence may also harm nontarget organisms. Knowledge sorption degradation essential optimize use for pest while minimizing environmental impact. We conducted studies on two origin, 2-propenyl benzyl isothiocyanate. The...
Abstract Natural isothiocyanates (ITCs) are toxic to a range of pathogenic soil‐living species, including nematodes and fungi, can thus be used as natural fumigants called biofumigants. hydrolysis products glucosinolates (GSLs) released from plants after cell rupture.
