Albaugh Obolo Star Pyriproxyfen 10% + Bifenthrin 10% EC Insecticide

Albaugh Obolo Star Pyriproxyfen 10% + Bifenthrin 10% EC Insecticide

Albaugh Obolo Star is a dual-action insecticide containing Pyriproxyfen 10% and Bifenthrin 10% EC, developed for effective management of whiteflies in cotton crops. The formulation combines an insect growth regulator (IGR) with a synthetic pyrethroid insecticide to control different developmental stages of whiteflies.

Pyriproxyfen interferes with normal insect growth and reproduction, while Bifenthrin provides contact and stomach action against susceptible adult insects. Together, these active ingredients help manage whitefly eggs, nymphs and adults. The formulation also provides translaminar activity, supporting control of whiteflies present on the underside of cotton leaves.

Product Details

Key Features and Benefits

• Dual-Action Formulation: Combines an insect growth regulator with a pyrethroid insecticide for whitefly management.
• Multiple Life-Stage Control: Targets whitefly eggs, developing nymphs and adults through complementary mechanisms.
• Inhibits Insect Development: Pyriproxyfen disrupts normal metamorphosis and reproduction.
• Adult Whitefly Knockdown: Bifenthrin provides contact action against susceptible adult whiteflies.
• Translaminar Activity: Helps control whiteflies feeding on the underside of cotton leaves.
• Helps Reduce Pest Buildup: Managing multiple insect life stages supports integrated whitefly management.

How Does Obolo Star Work?

Obolo Star combines two insecticidal modes of action.

Pyriproxyfen 10% – Insect Growth Regulator

Pyriproxyfen is a juvenile hormone mimic belonging to IRAC Group 7C. It interferes with normal insect development and reproduction, helping suppress whitefly populations by affecting immature stages and reproductive processes.

Bifenthrin 10% – Synthetic Pyrethroid

Bifenthrin belongs to IRAC Group 3A. It affects insect nervous-system function through sodium-channel modulation, producing contact and stomach toxicity in susceptible insects.

This combination provides complementary action against the different stages of the whitefly life cycle.

Recommended Crop and Target Pest

Crop: Cotton.

Target Pest: Whitefly (Bemisia tabaci).

Whiteflies usually feed on the undersides of cotton leaves and remove plant sap. Heavy infestations can cause leaf yellowing, honeydew deposition, sooty mould development and reduced plant vigour.

Whiteflies can also transmit cotton leaf curl disease. Obolo Star is an insecticide used for controlling the insect vector; it does not cure viral infection in affected plants.

Dosage and Application Method

Recommended Dosage: 240 ml per acre, according to Albaugh's official product recommendation.

Application: Foliar spraying.

Crop Stage: Vegetative growth stage, when whiteflies begin appearing and treatment is justified by pest monitoring.

Spray Water: Use the spray volume specified on the registered product label to achieve uniform coverage.

Waiting Period: Maintain a minimum 19-day pre-harvest interval as specified in the registered formulation reference.

How to Apply Obolo Star

1. Inspect cotton plants, especially the undersides of leaves, for whitefly infestation.
2. Confirm the treatment requirement according to local pest-monitoring recommendations.
3. Measure the product using the recommended per-acre dosage.
4. Fill the spray tank partially with clean water.
5. Add the measured product and mix thoroughly.
6. Add the remaining required water while maintaining agitation.
7. Use a calibrated knapsack sprayer with an appropriate hollow-cone nozzle.
8. Apply evenly over the foliage, including the undersides of leaves.

Best Time for Spraying

Apply when whiteflies begin appearing in the cotton field, preferably before pest populations exceed the locally recommended economic threshold.

Avoid spraying in strong winds, during rainfall or when temperatures are excessively high. Do not spray while bees are actively foraging or during flowering conditions where pollinators may be exposed.

Follow the registered label regarding repeat applications and spray intervals. Do not exceed the maximum number of applications allowed.

Important Precautions

• Use only for cotton whitefly management according to the approved label.
• Do not apply on other crops without registered approval.
• Wear suitable protective gloves, clothing and eye protection.
• Avoid inhaling spray mist and direct contact with skin or eyes.
• Highly hazardous to aquatic organisms; prevent spray drift and runoff into ponds, rivers and fish-rearing areas.
• Protect bees and other beneficial insects from direct spray exposure.
• Do not mix with other pesticides without checking label approval and compatibility.
• Alternate insecticides with different modes of action to support resistance management.
• Observe the specified pre-harvest waiting period.
• Store securely away from children, food, drinking water and animal feed.

Frequently Asked Questions

1. What is Albaugh Obolo Star?

Obolo Star is a dual-action insecticide containing Pyriproxyfen 10% and Bifenthrin 10% EC, recommended for controlling whiteflies in cotton.

2. Which insects does Obolo Star control?

The official recommendation identifies whiteflies in cotton, including management of different whitefly developmental stages.

3. What is the recommended dosage per acre?

Albaugh recommends 240 ml per acre for cotton whitefly management.

4. Does Obolo Star control whitefly eggs?

Yes. Its Pyriproxyfen component interferes with insect growth and reproductive development, contributing to egg and immature-stage control.

5. Can Obolo Star be sprayed on chilli or tomato?

The verified manufacturer recommendation is for cotton whiteflies. Do not extend the recommendation to other crops without approved label instructions.

6. Does Obolo Star cure cotton leaf curl virus?

No. It controls whitefly insects but does not directly treat viral infection in plants.

7. What is the waiting period before harvesting?

The registered formulation reference specifies a 19-day pre-harvest interval for cotton. Follow the current Obolo Star label.
