Herbicides and Their Respective Mode of Action

🌿 Herbicide	⚙️ Mode of Action
IPC (Chlorpropham)	Causes inhibition of epidermal to boundary layer formation
2,4-D (Ethyl ester)	Highly volatile – causes abnormal cell division
2,4-D (Sodium salt)	Highly soluble – causes abnormal cell division
Glyphosate	Non-selective, translocated, zero persistence; general metabolic inhibitor
Diquat	Disturbs cell membrane permeability
Triazines group	Photosynthesis inhibitor
Atrazine	Selective – detoxified by conjugation
Pendimethalin	Inhibits microtubule assembly
Paraquat	Contact herbicide – inhibits DNA synthesis
Dinitroaniline herbicides	Inhibition of respiration
Oxadiazon	Inhibition of CO₂ fixation
Trifluralin	Inhibition of RNA synthesis
Butachlor & Alachlor	Inhibition of protein synthesis and GA production during germination
Dalapon	Inhibition of vitamin synthesis
Thiocarbonates	Inhibition of lipid synthesis
Carbamate group	Inhibition of cell division
Auxin-type herbicides	Abnormal tissue development
Propanil	Degradation or rapid metabolism
2,4-DB	Reverse metabolism
Paraquat, Diquat & Glyphosate	Knock-down effect
