Response of cotton at different growth stages to imazapyr
Weed Technology, 2023 Abstract A significant proportion of the forested production area in South Carolina is managed using aerial applications of imazapyr. Cotton injury from off-target movement of imazapyr has been observed in South Carolina. Field experiments were conducted twice at the Edisto Research and Education Center (EREC) in 2021 and 2022, and once at the Pee ...

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 ...
