| Questão | Responda |
| Amide | Propanil Group 7 - photosynthesis inhibitors; photosystem II inhibitors. |
| Bipyridylium | Paraquat and diquat Group 22 - Cell membrane disrupter; photosystem I electron diverter. Inhibition of photosynthesis. |
| Dinitroaniline | Trifluralin and pendimethalin Group 3 - Seedling root growth inhibitor; microtubule inhibitor. Absorbed primarily by emerging roots. |
| Diphenylether | Oxyfluorfen Group 14 - Cell membrane disrupter, PPO inhibitor. Readily absorbed by leaves, chlorosis in leaves of susceptible plants, followed by desiccation and necrosis |
| Glycine | Glyphosate Group 9 - Amino acid synthesis inhibitor; EPSP synthase inhibitor. Absorbed by foliage; translocated throughout, including roots; growth inhibited soon after application. |
| Phenoxy, carboxylic acids | Auxinic herbicides, 2,4-D Group 4 - Growth regulators; synthesis auxins. Selective systemic. Salts rapidly absorbed by roots, esters by foliage. |
| Phosphinic acid | Glufosinate Group 10 - Nitrogen metabolism inhibitor; glutamine synthetase inhibitor. Mainly absorbed by foliage, causing chlorosis and wilting. Translocation limited. Inhibits the activity of glutamine synthase. |
| Sulfonylurea | Chlorsulfuron and Rimsulfuron Group 2 - Amino acid synthesis inhibitor; ALS inhibitor. Rapid foliar absorption but slower chlorosis and necrosis. Translocated. |
| Thiocarbamate | EPTC and Thiobencarb Group 8 - Seedling shoot growth inhibitors; Lipid synthesis inhibitor (not ACCase) |
| Triazine | Atrazine and Simazine Group 5 - Photosystem II inhibitors (different binding than groups 5 & 6). Absorbed through roots and leaves; translocated. Inhibits photosynthesis at Photosystem II. |
| Urea | Linuron and Diuron Group 7 - Photosynthesis Inhibitors; photosystem II inhibitor (different binding than groups 5 & 6). Readily absorbed by roots and, less so, by foliage and stems. Inhibits photosynthesis at Photosystem II. |
