Willowood Parafex Herbicide (Paraquat Dichloride 24% + Oxyfluorfen 5% SC)

Willowood Parafex Herbicide – Paraquat Dichloride 24% + Oxyfluorfen 5% SC for Tea

Willowood Parafex Herbicide contains Paraquat Dichloride 24% + Oxyfluorfen 5% SC. It is registered for weed management in tea plantations and combines two herbicidal active ingredients with different modes of action to help manage important grasses, sedges and broadleaf weeds.

Parafex acts rapidly on susceptible green weed tissue. Paraquat disrupts photosynthetic processes in treated foliage, while Oxyfluorfen inhibits protoporphyrinogen oxidase (PPO), resulting in cellular membrane damage in susceptible weeds. Accurate spray placement is important because spray reaching desirable green plant parts may cause crop injury.

Recommended Crop & Target Weeds

Dosage and Application

Apply the recommended quantity with sufficient clean water to obtain uniform coverage of the target weed foliage. Good spray coverage is important for effective weed management.

The approximate per-litre calculation should not replace the registered area-based application rate. Always follow the current Parafex label for exact spray timing, method and equipment recommendations.

Mode of Action

Paraquat Dichloride: Paraquat acts as a photosystem-I electron diverter. In exposed green plant tissue, it promotes the formation of reactive oxygen species that damage cell membranes and cause rapid drying of susceptible foliage.

Oxyfluorfen: Oxyfluorfen inhibits the enzyme protoporphyrinogen oxidase (PPO). This results in the accumulation of photoreactive compounds that damage plant cell membranes in susceptible weeds when exposed to light.

The combination of these two active ingredients provides effective foliar weed-management activity against the registered weed spectrum when the spray is applied correctly and uniformly.

How to Use Willowood Parafex

1. Identify the target weeds present in the tea plantation.
2. Measure the required quantity according to the recommended area-based dose.
3. Partially fill the spray tank with clean water.
4. Add the measured quantity of Parafex while mixing thoroughly.
5. Add the remaining required water and maintain proper agitation.
6. Apply uniformly to the target weed foliage using a directed spray.
7. Avoid spray reaching desirable green crop tissue and neighbouring vegetation.

Best Time to Apply

Apply when target weeds are actively growing and have sufficient foliage for uniform spray coverage. Weed-control performance may be reduced where weeds are severely stressed or spray coverage is inadequate.

Follow the current product label for the recommended weed growth stage, weather conditions and application timing.

Application Tips

• Ensure uniform coverage of the target weed foliage.
• Use clean water and properly calibrated spray equipment.
• Direct the spray carefully towards weeds.
• Avoid spray drift onto tea foliage or neighbouring crops.
• Do not spray during strong winds.
• Avoid application immediately before expected rainfall.
• Do not exceed the recommended label dose.
• Follow the prescribed waiting period before harvesting treated tea.
• Avoid contamination of ponds, streams, irrigation channels and aquaculture areas.

Safety Precautions

• Read the complete product label and accompanying leaflet before use.
• Wear appropriate protective clothing, chemical-resistant gloves, eye protection and other PPE specified on the label.
• Avoid inhaling spray mist and avoid direct exposure to skin, eyes or mouth.
• Do not eat, drink or smoke while mixing or applying the herbicide.
• Paraquat-containing products require careful handling and should never be transferred into food or beverage containers.
• Do not contaminate drinking water, ponds, streams, irrigation channels or aquaculture areas.
• Wash hands, exposed skin and spray equipment thoroughly after use.
• Store securely in the original container away from children, food, feed and animals.
