POMAIS Herbicide Oxadiazon 250G/L EC | Agrochemical Pesticide
Short Description:
Active Ingredient: Oxadiazon Herbicide 250G/L EC
CAS No.:19666-30-9
Application:Oxadione, also known as oxadiazon, is a nitrogen-containing heterocyclic herbicide developed by the French company Rhône-Poulenc. Its 12% EC trade name is “Ronstar”; it can exert herbicidal activity under the action of light. Plant buds, roots, stems and leaves absorb it, causing it to stop growing and then rot and die; at the same time, its herbicidal activity is 5 to 10 times higher than that of herbicidal ether, and its effect on stems and leaves is greater, and the resistance of rice roots is stronger. Mainly used for weeding in rice fields, it is also commonly used to control annual grass weeds and broadleaf weeds in peanuts, soybeans, cotton, potatoes, sugar cane, tea gardens, orchards.

Benefits of Oxadiazon
Oxadiazon offers several advantages that make it ideal for lawn and landscape maintenance.
Seasonal control
A single pre-emergence application of Oxadiazon provides weed control throughout the season, reducing the frequency and cost of maintenance.
No damage to turf roots
Oxadiazon does not inhibit the growth or recovery of turf roots, making it particularly suitable for spring applications without damaging labeled ornamentals.
Stabilization of Oxadiazon
Oxadiazon's stabilized liquid formulation allows for early application weeks before weeds and grasses germinate, giving it a significant advantage in weed control.
Oxadiazon for Sensitive Grasses
Oxadiazon is also an ideal choice for some sensitive grasses. Its specific chemical properties make it effective in controlling weeds without damaging the turf.
Mode of action of Oxadiazon Herbicide
Oxadiazon belongs to the chemical class that inhibits protoporphyrinogen oxidase (PPO) — a key enzyme in chlorophyll and carotenoid biosynthesis in plants.
Mechanism in brief:
- When soil is treated pre-emergence, Oxadiazon forms a protective barrier in the topsoil layer. Weed seeds germinating in treated soil absorb the active ingredient.
- PPO inhibition leads to accumulation of porphyrin intermediates, which under light catalyze production of reactive oxygen species (ROS), causing membrane damage and desiccation of seedlings.
- As a result, susceptible annual grasses and broadleaf weeds fail to establish, providing a residual weed-free window of several weeks to months depending on soil and climate conditions.
Because of this mode of action, Oxadiazon 250 g/L EC is particularly effective when applied before weed seed germination (pre-emergence) or in early weed germination stages, rather than on well-established weeds.
Application areas for Oxadiazon
Oxadiazon is widely used in all kinds of commercial places, its effect is remarkable and favored by users. The following are some of the main applications:
Golf courses and sports grounds
Where the neatness of the grass directly affects the user experience, Oxadiazon ensures that the grass is weed-free, allowing athletes to perform at their best.
Playgrounds and roadsides
At playgrounds and roadsides, where weeds not only detract from aesthetics, but can also pose a danger to children and pedestrians, Oxadiazon is used to ensure that playgrounds and roadsides are safe and aesthetically pleasing.
Industrial sites
At industrial sites, where weeds can interfere with the normal operation of equipment, Oxadiazon is used to effectively control the growth of weeds at industrial sites, ensuring that production runs smoothly.
Use of Oxadiazon on turf farms
Turf farms face the challenge of weed infestation and Oxadiazon provides the perfect solution. With a single pre-emergence application, Oxadiazon controls weeds throughout the season, keeping turf farms tidy and productive.
Oxadiazon in Ornamentals and Landscapes
Oxadiazon is not only for lawns, but is also effective on a wide variety of ornamentals and landscape plants. It does not inhibit the growth or recovery of turf roots, ensuring healthy plant growth.
Target Weeds, Crops & Use
Oxadiazon 250g/L EC is widely applicable across multiple cropping systems — key use cases include:
- Rice (paddy & upland): Prevents barnyardgrass, sedges, Echinochloa spp., Cyperus spp. and other annual grasses and broadleaf weeds after transplanting or before direct seeding.
- Field crops (cotton, sugarcane, soybean, peanut, etc.) — soil-applied pre-emergence to control annual weed pressure.
- Orchards & permanent crops: Weed control in inter-rows and between trees, especially pre-planting or before weed flush.
- Turf, ornamental, nursery & landscape: Pre-emergence weed control in turf, conifer nurseries, ornamental beds, flower beds; controlling annual grasses and broadleaf weeds without damaging established plants (when label permits).
- Non-crop or infrastructure areas: Weed suppression in non-cropped strips, roadsides, fence lines, non-functional land — as allowed by label and regulations.
This versatility makes Oxadiazon 250 g/L EC a multi-purpose herbicide suited for farms, plantations, nurseries, turf managers and landscape contractors.

Application Guidelines & Best Practices
To maximize efficacy and minimize risk:
- Timing: Apply pre-emergence — before weed seeds germinate; or early post-emergence if weed flush is early and seedlings are small. For rice, apply just after transplanting or before seeding, and follow with irrigation or maintain shallow water layer as required.
- Application method: Use a well-calibrated sprayer, ensure even coverage of soil surface, avoid overlapping and concentrate areas. Do not incorporate into soil; broadcasting spray only.
- Water management (for paddy): After application, maintain appropriate water layer (if required by local practice) or irrigate lightly to activate herbicide barrier; avoid deep flooding or heavy runoff which may reduce effectiveness or increase environmental risk.
- Spray safety: Do not spray under windy conditions, avoid drift; use personal protective equipment (PPE) — gloves, long sleeves/pants, eye protection, mask. Avoid spraying near water bodies, aquatic zones or pollinator habitats.
- Resistance & rotation: Since Oxadiazon is a PPO inhibitor, avoid overuse or repeated single-mode applications; rotate with herbicides of different modes (e.g. ALS inhibitors, HPPD inhibitors, or other families) to manage resistance.
Following these practices ensures stable weed control while managing environmental and regulatory risks.
