Coromandel Astra is a selective insecticide mainly used in paddy for controlling hopper pests. It works as a feeding blocker and helps stop sap-sucking insects from damaging the crop. Astra insecticide is especially useful against brown plant hopper and white-backed plant hopper, which can cause yellowing, hopper burn, weak tillers, and yield loss in rice. The product has systemic and translaminar movement, helping protect treated plants even when pests hide near the lower crop canopy. Coromandel Astra insecticide also reduces egg-laying ability in hoppers, which helps slow further pest multiplication. It works best when applied at the early stage of infestation before the hopper population crosses the economic threshold level.
Key Features and Benefits of Astra Insecticide:
Targeted Action: Coromandel Astra insecticide helps manage brown plant hopper and white-backed plant hopper in paddy.
Unique Action: Astra insecticide stops hopper feeding soon after exposure, helping protect the crop from fresh damage.
Complete Protection: The product moves within treated plant parts and helps protect areas that are not directly hit by spray droplets.
Reduces Egg Laying: Coromandel Astra insecticide affects hopper activity and helps reduce further multiplication in the field.
Good Rainfastness: Astra insecticide gives better staying ability after drying, helping maintain protection under normal field conditions.
Resistance Management: Astra insecticide has a different mode of action, making it useful in rotation with other insecticide groups.
Astra Insecticide Uses:
Planthoppers: Brown plant hopper and white-backed plant hopper in paddy.
Sap-Sucking Pest Damage: Yellowing, hopper burn, weak tillers, and poor plant vigour caused by hopper feeding.
Lower Canopy Pest Pressure: Hopper colonies that stay near the base of rice plants and suck plant sap.
Paddy Crop Protection: Early to moderate hopper infestation during vegetative to reproductive crop stages.
Coromandel Astra Dose:
Use as a foliar spray in paddy with clean water and proper lower-canopy coverage. Astra insecticide Dose is generally 120 gm per acre in 150 to 200 litres of water. The spray should be directed toward the lower portion of rice plants because hoppers usually stay near the base of the crop.
Crop | Target Pest | Dose per acre | Application Method | PHI |
|---|
Paddy | Brown plant hopper | 120 gm | Foliar spray in 150 to 200 L water | 19 days |
Paddy | White-backed plant hopper | 120 gm | Spray toward lower crop canopy | 19 days |
Paddy | Early hopper infestation | 120 gm | Apply when pest starts appearing in the field | 19 days |
How to Use Coromandel Astra Insecticide:
Measure the required quantity as per the paddy field area.
Fill the spray tank halfway with clean water.
Mix the measured granules in a small amount of water first.
Add the prepared mixture into the spray tank.
Add the remaining water and stir well.
Drain excess standing water if needed so the spray reaches the crop base properly.
Spray uniformly across the paddy field.
Aim the spray toward the lower plant canopy where hoppers are mostly found.
Apply when hopper population starts appearing, before heavy damage develops.
Avoid spraying during strong wind, rainfall, or very hot afternoon weather.
Use the prepared spray solution on the same day.
Best Time to Apply:
Apply Coromandel Astra insecticide when brown plant hopper or white-backed plant hopper activity is first noticed in the field. The best time is early morning or evening, when wind is low, and spray loss is reduced. The product gives better results when used before hopper population becomes heavy or hopper burn patches appear.
Frequency of Application and Re-entry Period:
Frequency of Application: One timely spray is generally suitable for early hopper pressure. Repeat only if pest pressure continues and label guidance allows it.
Re-Entry Period: Do not enter the treated field for at least 24 hours after spraying without proper protective gear.
Compatibility: Do not mix with highly acidic or highly alkaline products. For any tank mix, do a jar test first.
Application Care: Good coverage at the lower plant portion is important because hoppers usually remain close to the waterline and crop base.
Resistance Care: Rotate with other suitable insecticide groups and avoid repeated sprays of the same chemistry in one season.
Safety Precautions and Handling:
Read the label carefully before mixing and spraying.
Wear gloves, mask, goggles, long sleeves, and protective footwear during application.
Do not eat, drink, smoke, or chew anything while spraying.
Avoid direct contact with skin, eyes, and mouth.
Do not inhale spray mist or dust while preparing the solution.
Avoid spraying when bees and beneficial insects are actively moving in the crop.
Keep the product away from ponds, canals, drinking water, and fish farms.
Wash hands, face, and exposed skin properly after spraying.
