This is a list of herbicides. These are chemical compounds which have been registered as herbicides . The names on the list are the ISO common name for the active ingredient which is formulated into the branded product sold to end-users. [ 1 ]
Human health effects from 2,4,5-T at low environmental doses or at biomonitored levels from low environmental exposures are unknown. Intentional overdoses and unintentional high dose occupational exposures to chlorophenoxy acid herbicides have resulted in weakness, headache, dizziness, nausea, abdominal pain, myotonia, hypotension, renal and ...
2,6-Dichlorobenzonitrile (DCBN or dichlobenil) is an organic compound with the chemical formula C 6 H 3 Cl 2 CN. It is a white solid that is soluble in organic solvents. It is widely used as a herbicide and organic chemistry building block. [1]
The use of DCPA as a herbicide was first described in a patent filed in 1958. [12] The material was prepared as had been described in a 1948 research paper by treating terephthaloyl chloride with chlorine to give tetrachloroterephthaloyl chloride which was then esterified with methanol. [13] C 6 H 4 (COCl) 2 + 4 Cl 2 + Fe (cat.) → C 6 Cl 4 ...
Indian toxicity label system Toxicity symbol for European toxicity class I and class II. Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization.
The triketone herbicides were found to be effective on a wide range of commercially-important weed species and to have both pre- and post-emergence activity. [9] Mesotrione was chosen for development (by Zeneca Agrochemicals under the code number ZA1296) because it controls a wide range of broad-leaved weeds that compete with maize and can also suppress some annual grass weeds that may be ...
A study conducted by Cornell University showed that imazaquin ingested by humans and animals was excreted within 48 hours, 94% through urine and 4% through feces. The LD 50 for dogs, rats, rabbits, and female mice were each 1000 mg/kg, 5000 mg/kg, 2000 mg/kg, and 2363 mg/kg, respectively.
The purpose of the label is "to provide clear directions for effective product performance while minimizing risks to human health and the environment". A label is a legally binding document that mandates how the pesticide can and must be used and failure to follow the label as written when using the pesticide is a federal offence. [16] [17]
