Metolachlor
Mode of action: Inhibits protein synthesis and seedling development. Targets annual grasses and certain broadleaf weeds.
Glyphosate
Mode of action: Inhibits EPSP synthase in the shikimic acid pathway, leading to a reduction in aromatic amino acids. Targets a broad spectrum of weeds.
Dicamba
Mode of action: Mimics natural plant hormones (auxins) and disrupts cell division and growth. Targets broadleaf weeds.
Glufosinate
Mode of action: Inhibits the enzyme glutamine synthetase, leading to ammonia accumulation and plant death. Targets a broad spectrum of weeds.
2,4-D
Mode of action: Acts as a synthetic auxin, disrupting plant growth hormones. Targets broadleaf weeds.
Atrazine
Mode of action: Inhibits photosynthesis by binding to the D1 protein of the photosystem II. Targets broadleaf and some grassy weeds.
Trifluralin
Mode of action: Acts by inhibiting root and shoot development by disrupting microtubule formation. Targets annual grasses and broadleaf weeds.
Isoxaflutole
Mode of action: Inhibits the enzyme HPPD, disrupting carotenoid biosynthesis and causing plant bleaching. Targets broadleaf and grassy weeds.
Mesotrione
Mode of action: Inhibits the enzyme HPPD which is involved in carotenoid synthesis, preventing photosynthesis. Targets broadleaf and grassy weeds.
Pendimethalin
Mode of action: Inhibits cell division and cell elongation by disrupting microtubule assembly. Targets annual grasses and some broadleaf weeds.
