Purpose and Application








Brown Plant Hoppers



Pymetrozine 50% WG primarily acts as a contact and stomach poison, effectively managing a broad spectrum of pests. Its targeted application is on crops suffering from sap-sucking insects, providing a valuable solution for farmers dealing with such infestations.

Target Pests

Pymetrozine 50% WG is particularly effective against a range of insect pests, including but not limited to:

1. Aphids

Aphids are a notorious group of pests that can significantly damage crops by extracting plant sap. Pymetrozine acts by disrupting their feeding and inhibiting their growth.

2. Whiteflies

Whiteflies can cause substantial harm by draining the plant of vital nutrients. Pymetrozine effectively targets and controls whitefly infestations.

3. Leafhoppers

Leafhoppers are another group of pests that Pymetrozine is efficient in controlling. They are known for transmitting plant diseases and causing damage by feeding on plant juices.

4. Jassids

Jassids, commonly known as leafhoppers or leaf miners, can cause considerable damage to the leaves of plants. Pymetrozine effectively manages these pests.

Mode of Action

Pymetrozine, the active ingredient in this insecticide, operates through a mode of action called NACHR Competitive Modulator. It interferes with the nervous system of insects, disrupting their feeding and growth patterns. This mode of action ultimately leads to the control and reduction of insect populations, aiding in crop protection.


1. Effective Pest Control

Pymetrozine 50% WG is highly effective in controlling a wide range of sap-sucking insect pests that can otherwise damage crops.

2. Targeted Action

The insecticide targets specific pests, minimizing harm to beneficial insects and other non-target organisms.

3. Reduced Damage to Crops

By effectively managing pest populations, this insecticide helps in reducing crop damage, thus improving overall yield and quality.

4. Cost-Effective Solution

The concentrated formulation of Pymetrozine 50% WG ensures that only a small amount is needed per application, making it a cost-effective choice for farmers.
