What Is The Best Post Emergent Herbicide For Maize?
A post-emergent herbicide for maize is a chemical pesticide that is applied after the weed has emerged from the soil and is growing. It works by killing the weed, but not harming the maize plant. Examples of post-emergent herbicides for maize include 2,4-D, glyphosate, and atrazine
It’s important to follow the instructions carefully when applying these herbicides to maize, as they can be harmful if not used correctly.
It’s also important to keep children and pets away from areas where these herbicides are being applied.
Best 10 Post Emergent Herbicide For Maize In Kenya
In Kenya, some commonly used post-emergent herbicides for maize include:
- 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.
- 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.
- 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.
- 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.
- Halosulfuron: A sulfonylurea herbicide that controls sedges and some broadleaf weeds in maize. It is typically used as a post-emergence herbicide.
- Maximus: A herbicide that can be applied at the 2nd or 3rd leaf stage of maize, effective against both grasses and broadleaved weeds.
- 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.
- 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.
- 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.
- 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.
- Monolith: Contains mesotrione and is effective on grasses, particularly Brome. Plantback restriction with wheat or barley is only 4 months.
- 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.
- Servian: Specialized for Watergrass control, can be mixed with other herbicides where approved. Plantback restrictions apply.
- 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.
A post-emergent herbicide for maize in Kenya refers to a type of herbicide that is applied after the maize crop and weeds have emerged from the soil.
The choice of post-emergent herbicide depends on the weed species present, the growth stage of the maize crop, and local recommendations or regulations.
Proper application timing and rates are crucial for effective weed control and to avoid crop injury.
