Fipronil GR 0.2% Behavaran

• Fipronil GR 0.2% Behavaran is a granular agricultural insecticide containing 0.2% Fipronil as the active ingredient. Fipronil belongs to the phenylpyrazole chemical group and is classified under IRAC Group 2B according to its mode of action.
• The granular formulation is designed for specific registered agricultural applications where placement of the active ingredient in the soil or crop root zone is required. This makes the product suitable for selected pest management programs involving soil-associated or concealed pest stages.

Product Specifications

What Is Fipronil?

Fipronil is a broad-spectrum insecticidal active ingredient from the phenylpyrazole group. It affects the insect nervous system by interfering with GABA-gated chloride channels, disrupting normal nerve signal transmission.

This distinctive mode of action places Fipronil in IRAC Group 2B, making resistance management an important consideration when it is included in crop protection programs.

Mode of Action

Fipronil acts primarily on the insect nervous system. By blocking the normal function of chloride channels associated with the neurotransmitter GABA, it disturbs the electrical balance of nerve cells.

This interference leads to abnormal nervous activity and loss of normal physiological function in susceptible insects.

For resistance management, Fipronil should be used according to label directions and, where repeated treatments are required, rotated with insecticides belonging to different IRAC mode-of-action groups.

Registered Uses

According to the product information provided for this formulation, Fipronil GR 0.2% is used for the management of selected agricultural pests.

Application must always follow the registered label, local regulations, crop conditions, and professional agronomic recommendations.

Fipronil GR 0.2% for Grape Cicada

Grape cicada is an important vineyard pest whose immature stages may spend a significant part of their life cycle in the soil.

Nymphs feeding around the root system can gradually weaken grapevines and may contribute to:

• Reduced vine vigor
• Weak annual growth
• Lower plant vitality
• Reduced root performance
• Yield reduction under severe or prolonged infestation

Because a significant part of the pest population can remain below ground, proper monitoring of both the vine and the root zone is important when planning control measures.

Fipronil GR 0.2% for Rice Stem Borer

Rice stem borers are among the economically important pests of rice production. Their larvae damage stems by feeding within plant tissues, which can reduce crop performance and yield.

Effective management depends on:

• Proper field monitoring
• Correct pest identification
• Appropriate application timing
• Regional pest pressure
• Following registered pesticide recommendations

The correct timing of application is generally more important than unnecessary repeated pesticide use.

Benefits of the Granular Formulation

GR stands for Granule, meaning the active ingredient is formulated on solid granules for specific field or soil applications.

Potential advantages of a granular formulation include:

• Targeted application to the soil zone
• Suitability for selected soil-associated pests
• Convenient field distribution in registered uses
• Reduced spray drift compared with foliar spraying
• No spray solution preparation required for certain applications
• Suitable placement around the root zone where specified on the label

Role in Integrated Pest Management

Fipronil GR 0.2% Behavaran should be considered as part of an Integrated Pest Management (IPM) program rather than as a stand-alone control measure.

A comprehensive pest management program may include:

• Regular crop monitoring
• Accurate pest identification
• Weed and alternative-host management
• Maintaining healthy root systems
• Proper orchard or field sanitation
• Timely chemical intervention
• Rotation of insecticides with different modes of action

Combining cultural, biological and chemical strategies generally provides more sustainable pest control.

Resistance Management

Fipronil belongs to IRAC Group 2B.

Continuous or repeated use of insecticides with the same mode of action may increase the risk of resistance development in pest populations.

For better resistance management:

• Avoid unnecessary repeated applications
• Rotate with insecticides from different IRAC groups
• Follow the registered application rate
• Use chemical control only when justified by pest pressure
• Combine pesticide use with non-chemical IPM measures
