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.

- 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.
