BACKGROUND The dissipation kinetics of the herbicide sulcotrione sprayed 4 times on a French soil was studied using a laboratory microcosm approach. An advanced cultivation-based method was then used to isolate the bacteria responsible for biotransformation of sulcotrione. Chromatographic methods were employed as complementary tools to define its metabolic pathway. RESULTS Soil microflora was...

This paper describes the analysis procedure and results for environmental herbicide samples by a negative ESI LC-MS/MS method. After the preparation of aqueous and soil samples, the extracts are directly injected into a high performance liquid chromatography system coupled to negative eletrospray ionization (ESI-) tandem mass spectrometry. The sample preparation incorporates modified hydrolysis...

Adjuvants mayimprove control efficiency of volunteer RR® corn with ACCase inhibiting herbicides. Thus, the aim this study was to evaluate effects adjuvant addition herbicides clethodim and quizalofop, on surface tension, spray deposition control. The tension (96 g a.i. ha-1) quizalofop (60 without a mineral oil, vegetable oil an organosilicon evaluated at concentrations 0.01; 0.05; 0.1; 0.5; 1....

The synergistic interaction between mesotrione, a hydroxyphenylpyruvate dioxygenase (HPPD)-inhibiting herbicide, and atrazine, a photosystem II (PS II)-inhibiting herbicide, has been identified in the control of several weed species. A series of dose–response studies examined the synergistic effect of these herbicides on a susceptible (S) wild radish population. The potential for this interacti...

Early detection followed by the destruction of infected mats is one of the recommended and effective methods of controlling banana Xanthomonas wilt. As manual destruction is very tedious and time consuming, herbicide injections in the pseudostem or the stump were evaluated as a suitable alternative. The study was carried out in Luwero district in central Uganda. Herbicide injections were made o...

chickpea (cicer arietinum l.) is a dry pulse crop commonly used from old time. the chickpea yield is lower as compared to maximum potentials of the cultivars. the gap could mainly be attributed to the weed competition in addition to other production constraints. although chickpeas are traditionally grown on residual soil moisture, weeds competition pose major problem in many situations. in orde...
