GLOBAL AND LOCAL REACTIVITY DESCRIPTORS FOR PICLORAM HERBICIDE: A THEORETICAL QUANTUM STUDY

open access: yesQuímica Nova, 2015
In this work, we studied the reactivity of picloram in the aqueous phase at the B3LYP/6-311++G(2d,2p) and MP2/6-311++G(2d,2p) levels of theory through global and local reactivity descriptors.

Initial Post Seeding and Early Reconstruction Management, 2015 [PDF]

open access: yes, 2015
The establishment of a prairie plant community takes 3 to 5 years. Without early management of the vegetation during this critical time, weeds and woody plants will displace the emerging and newly established native plants resulting in a weedy plant ...

Chemical Warfare Through the Ages: A Systematic Review From Antiquity to the Present

open access: yesJournal of Toxicology, Volume 2025, Issue 1, 2025.
Chemical warfare means the use of chemical agents that have direct toxic effects on animals, plants and humans, as weapons. The first documented use of a chemical agent for warfare purposes occurred in ancient times around 10,000 BCE in South Africa when weapons were dipped in chemicals and then used to attack and defend from enemies.

Gas Chromatographic Determination of Picloram in Fish

open access: yesJournal of AOAC INTERNATIONAL, 1985
Abstract A simple method for determining picloram in fish is described. The sample is homogenized with ethyl acetate, acidified with IN HC1, and extracted twice more with ethyl acetate. Ethyl acetate fractions are pooled, derivatized with diazomethane, cleaned up by column chromatography, and analyzed by electron capture gas ...
