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 ...

Root exudation of imazapyr by eucalypt, cultivated in soil [PDF]
Planta Daninha, 2004 Imazapyr has been used to control stump sprouting in stand of Eucalyptus plantations, where herbicide is applied to the tree trunk before cutting. The herbicide is applied exclusively on the stump to be killed, but little is known about the final fate of the molecule. Imazapyr exudation via roots of eucalypt grown in soil as the substrate was evaluated
