Contemporary farming practices and rapid industrialization over the last few decades, have raised significant soil water pollution with extreme toxic effects to humans ecosystems. The widespread inefficient use of pesticides, which surpass soil’s self purification capability, has accelerated pollution. In this study, wheat straw biochar was obtained using traditional pyrolysis technique its cha...

In this paper, a multiresidue method for the analysis in soils of metribuzin (M) and its major conversion products, deaminometribuzin (DA), diketometribuzin (DK) and deaminodiketometribuzin (DADK) is developed. Considering the neutral and charged nature of the molecules, micellar electrokinetic chromatography (MEKC) is a very efficient method for the separation of these compounds, providing hig...

Echinacea is a perennial plant that used for its phytotherapeutic potential. crops are often affected by invasive weeds. One of the most effective strategies in weed control use chemicals such as herbicides. However, herbicides also affect physiological and morphological processes Echinacea. For this reason, aim study was to determine effects different dosages (0, 250, 500, 750, 1000, 1250 g ha...

Metribuzin (MTB) is a herbicide widely used for weed control in growing soybeans and other crops and has been identified in many parts of the world as a groundwater contaminant. To prepare controlled-release formulations (CRFs) of MTB, it was entrapped within a sepiolite-gel-based matrix with one of two proportions of clay/herbicide and used as either a gel or powder after freeze-drying. To det...

Triazine-resistant chloroplasts o f the Canadian spring oilseed rape variety OAC Triton were transferred into four German winter oilseed rape lines and two cultivars o f double-low quality by means o f protoplast fusion. X-irradiation has been used to reduce the amount o f nuclear D N A o f the spring type cultivar and to promote cybrid formation. RFLP-analysis showed that some regenerants and ...
