Plastoquinone is, in turn, a critical co-factor in the formation of carotenoids, which protect chlorophyll in plants from being destroyed by sunlight. [4] This class of herbicides represents one of the last discoveries of a new herbicide mode of action in the wave of discovery that ended in late 1990s. [3] [7]

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]
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.
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).
It has been found nontoxic to bees and marginally toxic to fish (rainbow trout LC 50 (96 hr) = 117 ppm). [ 4 ] Garlon's fact sheet for their triclopyr ester product indicates that triclopyr is highly toxic to fish, aquatic plants, and aquatic invertebrates, and should never be used in waterways, wetlands, or other sensitive habitats.

Glufosinate is a broad-spectrum herbicide that is used to control important weeds such as morning glories, hemp sesbania (Sesbania bispinosa), Pennsylvania smartweed (Polygonum pensylvanicum) and yellow nutsedge similar to glyphosate. It is applied to young plants during early development for full effectiveness. [3]
