This salt is one of the most widely used herbicides worldwide. [6] It is quick-acting and non-selective, killing green plant tissue on contact. Paraquat is toxic (lethal) to human beings and animals. Paraquat's poisoning and lethality depends on the dose and how the herbicide is absorbed by the body.
A particularly efficient form of pesticide dose transfer is seed treatment and specific formulations have been developed for this purpose. A number of pesticide bait formulations are available for rodent pest control, etc.
A manual backpack-type sprayer Space treatment against mosquitoes using a thermal fogger Grubbs Vocational College students spraying Irish potatoes. Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.
In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose. If multiple doses of treatment are needed in a day, the physician must take into account information regarding the total amount of the drug which is safe to use in one day, and how that should be broken up ...
Glyphosate-based formulations may contain a number of adjuvants, the identities of which may be proprietary. [12] Surfactants are used in herbicide formulations as wetting agents, to maximize coverage and aid penetration of the herbicide(s) through plant leaves. As agricultural spray adjuvants, surfactants may be pre-mixed into commercial ...
Oral lethal dose (mg/kg) Listed chemicals Red label Extremely toxic 1–50 Monocrotophos, zinc phosphide, ethyl mercury acetate, and others. Yellow label Highly toxic 51–500 Endosulfan, carbaryl, [2] quinalphos, [2] and others. Blue label Moderately toxic 501–5000 Malathion, thiram, glyphosate, [2] and others. Green label Slightly toxic > 5000
The system is based on LD50 determination in rats, thus an oral solid agent with an LD50 at 5 mg or less/kg bodyweight is Class Ia, at 5–50 mg/kg is Class Ib, LD50 at 50–2000 mg/kg is Class II, and at LD50 at the concentration more than 2000 mg/kg is classified as Class III. Values may differ for liquid oral agents and dermal agents. [1]
