Oxyfen 24 Percent EC Selective Herbicide Onion Herbicide 1L – Efficient Post Emergent Weed Control

Oxyfen 24 Percent EC Selective Herbicide Onion Herbicide 1L – Efficient Post Emergent Weed Control

Oxyfen 24 Percent EC is a specialized post emergent herbicide designed for onion farming. It provides selective control of a wide range of annual broadleaf weeds and some grasses without harming the onion crop. With its active ingredient oxyfluorfen, this herbicide offers quick knockdown and residual action to keep fields clean during the early stages of growth. It is suitable for both small scale and commercial onion producers across Kenya.

Key Features of Oxyfen 24 Percent EC

• Selective post emergent action safe for onions
• Fast acting formula that visibly affects weeds within days
• Controls broadleaf weeds and suppresses some grasses
• Residual soil activity reduces need for frequent applications
• Minimizes manual labor in weed removal
• Supports cleaner fields and improved crop development
• Ideal for use in both dry and irrigated onion farms

Active Ingredient

Oxyfen 24 Percent EC contains 240 grams per liter of oxyfluorfen, a diphenyl ether herbicide. It works by inhibiting protoporphyrinogen oxidase, causing membrane disruption in sensitive weeds. The result is rapid desiccation of weeds after foliar contact.

Weeds Controlled

• Pigweed
• Blackjack
• Amaranthus
• Gallant soldier
• Spider flower
• Nightshade
• Mexican marigold
• Other annual broadleaf weeds

Recommended Crop

• Onions at 2 to 3 true leaf stage

Application Guidelines

• Apply post emergence when onions have formed true leaves and weeds have emerged
• Spray using a flat fan nozzle with even coverage
• Avoid application on stressed or waterlogged plants
• Use clean water and avoid tank mixtures unless tested
• Ensure no rainfall or irrigation for 6 hours after spraying

Recommended Dosage

Apply at a rate of 1 liter per hectare using 200 to 300 liters of water. Adjust based on weed density and growth stage. For spot treatment, mix 20 to 25 milliliters per 20 liters of water. Repeat applications only if necessary and in line with onion crop stage.

Safety and Handling

• Wear gloves, protective clothing, and a mask during application
• Keep product away from food and animal feeds
• Do not apply near water sources
• Wash hands and equipment after use
• Store in a cool dry place out of reach of children

Environmental Precautions

Oxyfen 24 Percent EC is low in environmental toxicity when used correctly. Avoid spraying on windy days to prevent drift. Dispose of empty containers responsibly through certified waste programs or return to licensed vendors for disposal.

Case Study One – Onion Farmer in Nyandarua

A farmer in Nyandarua faced recurring broadleaf weed infestation in his onion plots. After switching to Oxyfen 24 Percent EC, weeds were suppressed within three days of application. The clean field allowed better bulb formation, reduced labor costs, and resulted in a 35 percent yield increase.

Case Study Two – Irrigated Onion Project in Isiolo

A community based irrigation project in Isiolo introduced Oxyfen 24 Percent EC to tackle weed problems in onion beds. The herbicide performed well even in high temperatures and sandy soils. Extension officers reported significant improvement in field hygiene and reduced weeding intervals across over 20 acres.
