What is RONFEN insecticide?

RONFEN is a broad-spectrum insecticide widely used in Indian agriculture for the effective control of sucking and chewing pests. With its dual action—contact and systemic—it ensures that insects are eliminated quickly and crops are protected for a longer duration.

The formulation is carefully designed to penetrate plant tissues and safeguard crops from both visible and hidden pests. Farmers prefer RONFEN due to its reliability, affordability, and efficiency in improving crop health and productivity.

Chemical Composition

Technical Name: Pyriproxyfen 8% + Dinotefuron 5% Diafenthiuron 18% SC.

The active ingredients in RONFEN vary depending on the manufacturer’s formulation, but typically it contains a blend of fenvalerate (a synthetic pyrethroid) and other insecticidal compounds. These work together to disrupt the nervous system of insects, leading to paralysis and death.

Key Benefits of RONFEN

Effective Pest Control – Works on major pests like aphids, jassids, thrips, bollworms, and caterpillars.

Dual Action – Offers both systemic and contact activity for better coverage.

Long-Lasting Protection – Provides a residual effect, reducing the need for frequent spraying.

Improved Crop Quality – Protects leaves, flowers, and fruits, ensuring higher yield and better market value.

Cost-Effective – Affordable for small and medium farmers, ensuring higher returns on investment.

Recommended Crops

It insecticide can be safely used across a wide range of crops. Commonly recommended crops include:

Cotton – For controlling bollworms, aphids, and jassids.

Vegetables (brinjal, tomato, chili, okra, etc.) – Effective against fruit borers and sucking pests.

Pulses – Protection from pod borers and leafhoppers.

Oilseeds (mustard, groundnut, and soybean)—Controls thrips, caterpillars, and aphids.

Cereals (Rice, Maize, Wheat) – Manages stem borers and leaf folders.

Mode of Action

It works by disrupting the insect’s nervous system. When pests come in contact with or ingest the insecticide, it interferes with their nerve transmission, causing hyperactivity, paralysis, and eventually death. Its systemic action ensures protection even against hidden pests in plant tissues.

Recommended Dose

The dose depends on the crop and the level of pest infestation. Generally:

For field crops: 400–600 ml per acre, diluted in 200–250 liters of water.

For vegetables: 300–500 ml per acre, depending on pest intensity.

(Always follow the manufacturer’s label instructions for accurate dosage.)

Introduction of Bayer Lesenta Insecticide

Bayer Lesenta is a powerful, dual-action insecticide designed to help farmers combat a broad range of sucking and soil pests that damage key crops like sugarcane, cotton, and groundnut. This product from Bayer CropScience combines two potent active ingredients to provide systemic and contact action—ensuring stronger pest control and healthier crop growth. 

What Is Bayer Lesenta?

Bayer Lesenta is a ready-to-use insecticide formulated as water-dispersible granules (WG). It is specifically developed to control chronic pest problems that significantly reduce crop yields. The combination of two active ingredients gives it enhanced effectiveness and makes it suitable for multiple pest-control scenarios. 

Technical Name & Active Ingredients

The technical name or composition of Bayer Lesenta is:

Imidacloprid 40% + Fipronil 40% WG (80 WG) – This blend offers a dual mode of action:

Bayer Lesenta Content / Chemical Composition

Each packet of Lesenta contains: Imidacloprid – 40% w/w Fipronil – 40% w/w Water-dispersible granule formulation (WG) This combination provides effective control of pests such as white grubs, jassids, thrips, aphids, and other key insects. 

Bayer Lesenta Uses in Agriculture

Lesenta is used to protect crops against a wide range of pests:

Primary Crops & Target Pests

Sugarcane: White grubs (soil-dwelling larvae)

Groundnut: White grubs

Cotton: Jassids and thrips

Chilli: White grubs and termites

Other crops: Effective against aphids, whiteflies, caterpillars, root weevils, and cutworms in some regions (consult local recommendations). 

It can be applied as a foliar spray, soil drench, or seed treatment (depending on the crop and pest). Always follow the label for the correct method. 

Recommended Dosage (Per Acre & Per Litre)

Bayer Lesenta is effective even at low doses when applied correctly. Below are general guidelines based on common crop requirements (always check the product label for exact instructions and safety measures):

Dose Per Acre (Typical Use)

CropTarget PestDosage (g/acre)Water (Approx.)Waiting PeriodSugarcaneWhite grubs175–200 g400–500 L~296 daysGroundnutWhite grubs100–120 g400 L~106 daysCottonJassids, Thrips~50–125 g200 L~36 daysChilliGrubs, Termites~200 g400 L~3 days

Bayer Lesenta Dose Per Litre of Water

To prepare solution for spraying:

 A common foliar spray concentration is around 1 g per litre of water (which means 1 gm Lesenta mixed in 1 L water). This concentration ensures good coverage for sucking pests when sprayed evenly over the crop canopy.

In a standard 15 L pump sprayer, this translates to about 15 g per pump — but always adjust based on crop size, water volume, and pest severity. 

Benefits of Bayer Lesenta Insecticide

Using Bayer Lesenta offers multiple advantages to farmers:

1. Dual Mode of ActionLesenta’s combination of systemic (Imidacloprid) and contact/ingestion (Fipronil) action means more complete pest control. 

2. Effective Against Multiple PestsControls both soil-dwelling pests (like white grubs) and foliar pests (like jassids and thrips), reducing crop damage across growth stages. 

3. Extended Residual ProtectionOnce applied, Lesenta remains active longer than many single-ingredient products, lowering the frequency of spray applications needed. 

4. Growth Promotion EffectsFarmers often observe improved plant vigor, root development, and greener crops, which can contribute to higher yields.
