Bayer Ricestar is a selective post-emergent herbicide used for grassy weed control in paddy and contains Fenoxaprop-p-ethyl 6.9% EC, which is absorbed through weed leaves and stems after spraying. It works by disturbing fatty acid formation in grassy weeds, so their growth stops and they slowly dry. Ricestar herbicide is mainly useful against Echinochloa-type weeds, including jungle rice and barnyard grass, which compete strongly with paddy for nutrients, sunlight, space, and water. This herbicide has good crop selectivity when used at the correct stage and dose. The Ricestar herbicide works best when weeds are young, active, and at the 3 to 5 leaf stage.
Key Features and Benefits of Ricestar herbicide:
Selective Control: Bayer Ricestar controls grassy weeds in paddy while keeping the rice crop safe when used at the recommended dose.
Systemic Action: Ricestar herbicide enters through leaves and stems, then moves inside the weed to stop further growth.
Targeted Protection: Bayer Ricestar is useful against jungle rice, barnyard grass, and similar grassy weeds that cause heavy competition in paddy.
Early Post-Emergent Use: Ricestar herbicide can be sprayed after weeds emerge, giving farmers a practical window for corrective weed control.
Reduces Labour Need: Ricestar herbicide helps reduce repeated hand weeding, saving time and labour during the early crop period.
Ricestar Herbicide Uses:
Grassy Weeds: Jungle rice, barnyard grass, Echinochloa colona, Echinochloa crus-galli, and similar narrow-leaf weeds.
Paddy Weed Pressure: Grasses that emerge after sowing or transplanting and compete with paddy during early crop growth.
Late-Emerging Grasses: Fresh grassy weed flushes that appear after the crop has already established.
Selective Rice Weed Control: Paddy fields where only grass weed control is needed, and broadleaf or sedge weeds are not the main problem.
Bayer Ricestar Dose:
Use Bayer Ricestar as a foliar post-emergence spray in paddy. Ricestar Herbicide Dose is generally 350 ml per acre in 150 to 200 litres of clean water. Fenoxaprop-p-ethyl 6.9% EC should be sprayed evenly on actively growing weeds for better absorption. Ricestar herbicide should not be applied on dry, stressed, submerged, or muddy weeds.
Crop | Target Weed | Dose per acre | Application Method | PHI |
Paddy / Rice | Jungle rice and barnyard grass | 350 ml | Foliar spray in 150 to 200 L water | 61 days |
Paddy / Rice | Echinochloa colona and Echinochloa crus-galli | 350 ml | Early post-emergent spray at 3 to 5 leaf weed stage | 61 days |
Paddy / Rice | Late-emerging grassy weeds | 350 ml | Uniform spray after draining standing water | 61 days |
How to Use Bayer Ricestar:
Measure the required quantity of Bayer Ricestar as per the acreage.
Fill the spray tank halfway with clean water.
Add the measured Ricestar herbicide into a small amount of water first.
Mix Fenoxaprop-p-ethyl 6.9% EC properly before adding it to the spray tank.
Add the remaining water and stir the spray solution well.
Drain standing water from the paddy field before spraying Bayer Ricestar.
Spray Ricestar herbicide uniformly on exposed grassy weeds.
Use a flat fan nozzle for better weed coverage.
Spray Fenoxaprop-p-ethyl 6.9% EC when grasses are at the 3 to 5 leaf stage.
Do not spray Bayer Ricestar during strong wind, heavy rain, or very hot afternoon weather.
Use the prepared Ricestar herbicide spray solution on the same day.
Best Time to Apply:
Apply Bayer Ricestar as an early post-emergent spray when grassy weeds are young and actively growing. The best stage is usually the 3- to 5-leaf stage of weeds, often around 15 to 25 days after sowing or transplanting, depending on field condition. Ricestar herbicide works better when the field is moist, but weeds are not fully submerged. Morning or evening spray is better for lower drift and better coverage.
Frequency of Application and Re-entry Period:
Frequency of Application: One proper Bayer Ricestar spray is generally enough for early grassy weed control in paddy.
Re-Entry Period: Do not enter the treated field for at least 24 hours after Ricestar herbicide application without protective clothing.
Compatibility: Do not mix Bayer Ricestar blindly with other herbicides, insecticides, fungicides, fertilizers, or growth products. Always do a jar test first.
Water Management: Drain standing water before spraying Ricestar herbicide, and avoid immediate flooding after application.
Resistance Care: Rotate Fenoxaprop-p-ethyl 6.9% EC with other weed management methods to reduce resistance pressure in grassy weeds.
Safety Precautions and Handling:
Read the Bayer Ricestar label carefully before use.
Wear gloves, mask, goggles, long sleeves, and protective footwear while mixing and spraying Ricestar herbicide.
Do not eat, drink, smoke, or chew anything during Bayer Ricestar application.
Avoid direct contact of Fenoxaprop-p-ethyl 6.9% EC with skin, eyes, and mouth.
Do not inhale spray mist while applying Ricestar herbicide in the field.
Do not apply the herbicide directly on top of crops other than recommended paddy.
Keep Bayer Ricestar away from ponds, canals, fish farms, and drinking water sources.
Wash hands, face, and exposed skin properly after spraying.
