2,4-Dichlorophenoxyacetic acid (2,4-D)
Selective post-emergence herbicide that mimics natural plant hormones (auxins) and disrupts growth processes.
Glufosinate
Non-selective contact herbicide that inhibits glutamine synthetase leading to ammonia accumulation and plant death.
Flumioxazin
Selective pre-emergence herbicide that leads to the formation of reactive oxygen species, destroying cell membranes.
Imazethapyr
Selective post-emergence herbicide that inhibits branched-chain amino acid synthesis, leading to disruption of DNA synthesis.
Atrazine
Selective systemic herbicide that inhibits photosynthesis by binding to the Qb protein in the photosystem II.
Glyphosate
Non-selective systemic herbicide that inhibits aromatic amino acid biosynthesis (EPSP synthase).
S-Metolachlor
Selective pre-emergence herbicide that inhibits the elongation of the plant's shoot and root at the growth meristem.
Dicamba
Selective post-emergence herbicide that mimics natural plant hormones (auxins) similar to 2,4-D and affects growth.
Pendimethalin
Selective pre-emergence herbicide that inhibits cell division and cell elongation by disrupting microtubule assembly.
Mesotrione
Selective systemic herbicide that inhibits 4-hydroxyphenylpyruvate dioxygenase (HPPD), affecting carotenoid biosynthesis.
