About OZONE Herbicide
OZONE herbicide is a broad spectrum, non-selective, contact and post-emergence herbicide containing Paraquat Dichloride 24% SL as its active ingredient. It is used for the control of broadleaf weeds and grasses in wheat, cotton, potato, rice, maize, plantation crops and non-crop areas.
OZONE Technical Name
Paraquat Dichloride 24% SL
Product Specifications
Mode of Entry: Contact action with limited translocation
Time of Application: Post-emergence
Mode of Action: OZONE interferes with the photosynthesis process inside weed plants. During photosynthesis, it produces reactive compounds that damage weed cell membranes and cytoplasm. This causes burning and drying of green plant tissues. It works mainly through direct contact with green weed foliage, so only the sprayed plant parts are affected.
Key Benefits of OZONE Herbicide
- Fast weed burndown: It quickly dries weeds after spraying.
- Useful for directed spray: It is suitable for inter-row and plantation weed management.
- Ideal for minimum tillage systems: It helps to manage weeds without disturbing the soil.
- Effective on succulent weeds: It provides better results on actively growing weeds.

Effective on Weed Types: Broadleaf weeds, Grassy weeds, Sedges, Annual weeds, Some perennial weeds

Method of Application
Apply OZONE as a directed foliar spray or blanket spray using a knapsack sprayer, foot sprayer, compression knapsack sprayer, or power sprayer fitted with a flat-fan or flood-jet nozzle.
Best Time to Spray
- Spray on succulent and actively growing weeds.
- Directed spray is preferred in plantation and row crops.
- In rice and maize, blanket spray may be used before sowing or pre-ploughing as recommended.
- Avoid spraying during windy conditions or immediately before rain.
- Morning or late afternoon spraying gives better coverage.
