Nanoparticles Based on Chitosan as Carriers for the Combined Herbicides Imazapic and Imazapyr [PDF]

Scientific Reports, 2016
AbstractThe use of lower concentrations and fewer applications of herbicides is one of the prime objectives of the sustainable agriculture as it decreases the toxicity to non-targeted organisms and the risk of wider environmental contamination. In the present work, nanoparticles were developed for encapsulation of the herbicides imazapic and imazapyr ...

Selection of tolerant species to imazapic for potential use in phytoremediation

Revista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2020
Using herbicides results in environmental impacts and it is necessary employing sustainable technologies to reduce its residues in the soil. Imazapic, used in the sugarcane cultivation, shows persistence and mobility in the environment. This study aimed to identify plant species tolerant to imazapic with the potential for phytoremediation of soils with
