In Kenya, some commonly used post-emergent herbicides for maize include:

  1. Nicosulfuron: This is a selective herbicide that controls grassy weeds like crabgrass, foxtail, and quackgrass in maize fields. It is usually applied when the maize is between the 2-8 leaf stage.
  2. Tembotrione: This is a systemic herbicide that controls both grassy and broadleaf weeds in maize. It can be applied from the 2-8 leaf stage of maize.
  3. Atrazine: A triazine herbicide that controls many broadleaf and some grassy weeds in maize. It is often used in combination with other herbicides for better weed control.
  4. 2,4-D: A selective herbicide that controls broadleaf weeds in maize. It is usually applied when the maize is between the 4-8 leaf stage.
  5. Halosulfuron: A sulfonylurea herbicide that controls sedges and some broadleaf weeds in maize. It is typically used as a post-emergence herbicide.
  6. Maximus: A herbicide that can be applied at the 2nd or 3rd leaf stage of maize, effective against both grasses and broadleaved weeds.
  7. Stellar Star: Particularly strong on Gallant Soldier, Datura, and Mexican Marigold, but may be slightly weak on some populations of Amaranthus. Effective up to the 7-8 leaf stage of maize.
  8. Lumax: Known for its effectiveness on a wide spectrum of weeds, although it may struggle with large Amaranthus and Gallant Soldier. Strongest on grass weeds, controlling Brome, Ryegrass, Napier Grass, and Setaria.
  9. Governor: A generic alternative to Lumax, slightly safer on the crop due to the presence of acetochlor instead of metolochor. Effective but slightly weaker on established grasses.
  10. Surestart: Ideal for controlling Crotalaria or volunteer potatoes, best applied up to the 3 leaf stage of maize. Contains Sulphonyl-urea nicosulfuron, excellent on grasses, especially Brome.
  11. Monolith: Contains mesotrione and is effective on grasses, particularly Brome. Plantback restriction with wheat or barley is only 4 months.
  12. Auxo: Offers a range of weed activities including Gallant Soldier and Blackjack. Relies on bromoxynil, which can scorch the crop in hot conditions. Effective on various weeds but caution is required.
  13. Servian: Specialized for Watergrass control, can be mixed with other herbicides where approved. Plantback restrictions apply.
  14. Buctril, Badge & Breakdown: Broadleaved weed control options approved for maize, effective against brassicas, Gallant Soldier, and Datura. Limited grass activity and may struggle on Amaranthus.
