Pymetrozine 50% WG Systemic Feeding Inhibition Technology

Pre Alert Systemic Insecticide for Brown Plant Hopper, Aphid & Whitefly Control in Paddy

Pre Alert is a systemic insecticide containing Pymetrozine 50% WG. It is specially recommended for the control of Brown Plant Hopper in rice crop and also helps manage aphids and whiteflies as per crop recommendation. Pre Alert works by stopping insect feeding through nervous system action, providing immediate crop protection after application. Even pests not directly hit by spray can be controlled due to systemic movement within the plant. It is selective, IPM-friendly, and supports crop quality improvement when used as recommended.

The Science Behind

How Pre Alert Works

Understanding how Pymetrozine 50% WG works through systemic movement, nervous system feeding inhibition, hopper control, selective insect action, and quick crop protection support.

MAIN INGREDIENT

Pymetrozine 50% WG

Pre Alert contains Pymetrozine 50% WG, a systemic insecticide recommended for Brown Plant Hopper control in rice crop. After application, it circulates within the plant and helps control pests even when they are not directly hit by the spray. Pymetrozine binds to neuronal receptors and acts on the insect nervous system, creating inhibition of feeding capability. As a result, pests stop feeding and gradually die, reducing crop damage and supporting healthier paddy growth.

Systemic Crop Protection

Pre Alert moves within the plant and helps control pests feeding on treated crop tissues.

Feeding Inhibition Action

Pymetrozine stops pest feeding by acting on nervous system receptors linked to feeding capability.

Selective Hopper Management

Helps manage Brown Plant Hopper in paddy while being selective and suitable for IPM-based crop protection planning.

The Complete Process

1

Foliar Spray Application 💧

Pre Alert is applied at 120–150 gm per acre as a foliar spray in paddy crop.

2

Systemic Plant Movement

Pymetrozine circulates within the plant and helps protect crop tissues from feeding pests.

3

Nervous System Feeding Inhibition 🫧

The active ingredient binds to neuronal receptors and affects the feeding capability of insects.

4

Pest Feeding Stops

Target pests stop feeding, helping reduce crop damage and pest activity.

✓

Better Paddy Protection! 🌿

The crop receives quick protection support, improved crop quality, lower pest pressure, and healthier growth.

Detailed Process Breakdown

Each stage of Pre Alert’s foliar application, systemic plant movement, nervous system action, feeding inhibition, selective pest control, IPM fit, and crop quality support process.

Stage 1

Foliar Spray Application

Apply Pre Alert as a foliar spray at the recommended dose for paddy pest management.

Stage 2

Systemic Protection

Pymetrozine moves within the plant and supports control of pests not directly hit by spray.

Stage 3

Neuronal Receptor Binding

The active ingredient binds to neuronal receptors and affects the insect nervous system.

Stage 4

Permanent Feeding Inhibition

Pre Alert stops the feeding capability of target pests, providing immediate crop protection support.

Stage 5

Brown Plant Hopper Control

Recommended for effective management of Brown Plant Hopper in rice crop.

Continuous

Crop Quality Support

Helps improve crop quality, supports IPM programs, and has low impact on beneficial insects when used as recommended.

The Science Behind It

Pre Alert works through Pymetrozine 50% WG, a systemic insecticide that acts on the insect nervous system. It binds to neuronal receptors and creates nervous inhibition of feeding capability. After exposure, pests stop feeding and gradually die, helping protect the crop from further damage. Its systemic movement helps control pests even when they are not directly hit by spray, making it useful for Brown Plant Hopper management in rice crop.
