Keefun belongs to pyrazole group, a novel chemistry effective on Lepidopteran & sucking pests on wide range of crops. Globally, Keefun has been developed to control wide range of insect pests viz hoppers, aphids, Diamond Back Moth, Tobacco caterpillar (Spodoptera), bugs, Scale insects, psylla, thrips, borer, leaf miner, mites etc and some fungal diseases on vegetables, fruits, field crops. In india, Keefun has been approved for usage on DBM & sucking pests like Thrips, Jassids, Aphids etc.

Trade Name: Keefun

Active Ingredient: Tolfenpyrad

Formulation: 15% EC

Features Benefits
Broad spectrum of activity Keefun is highly effective against a broad range of sucking pests (viz, jassids, thrips, aphids) and chewing and biting pests (Diamond Back Moth or DBM). Thus keefun works as one shot solution for more than one target pests also reducing the cost of crop protection.
Different Mode of Action Highly effective on insects resistant to the other existing insecticides.
Anti-feedent action Due to its anti-feedent action, target pests' stops feeding immediately after coming in contact with Keefun.
Active on different developmental stages Due to Keefun's activity on different developmental stages i.e. eggs, larvae/nymphs and adults of the target pests, Keefun offers fast and effective control.
Fast and Effective control of target pests leads to a healthy crop

Mode of Action

Keefun is a METI (Mitochondrial Electron Transfer Inhibitor) compound which acts through contact and ingestion. Keefun inhibits the electron transport chain in the mitochondria of the cell, leading to the cessation of the production and supply of the energy in the cell, resulting in the death of the target pest.

Method of application

For effective results, Keefun should be used at the initial stage of the crop and insect. Ensure thorough and uniform coverage by using hollow cone nozzle. Rotate with insecticide of different mode of action to avoid resistance development. Avoid spray of keefun if the rains are expected earlier than 6 hours.
