bollworms and sucking pests, and specified pests in cauliflower, brinjal and okra. Cotton pest groups require different
rates.

maturity.
Important distinction: Cotton bollworms and cotton aphids, jassids and thrips have
separate product and water quantities.

in cotton through contact action.

aphids, jassids and thrips at their separate rate.

How It Works: Mode of Action
Tatafen affects the nerves of susceptible insects that contact the
treatment.
-
Reach the pest: Apply the crop-specific foliar spray to expose the target pest.
-
Disrupt nerve signals: Fenvalerate interferes with normal nerve signalling, affecting movement and survival.
-
Plan resistance management: Other Group 3A products use the same mode of action. A different brand alone is not a rotation.

How to Apply: Best Practices
-
Time the spray: Treat at pest appearance within the stated crop stage. Morning or evening is preferable; avoid rain, wind and hot
sunshine.
-
Match the equipment: Use hand-compression equipment with the water volumes above. Mist-blower and low-volume directions are
separate; do not copy the high-volume water amount to another system. Do not use ultra-low-volume spraying.
-
Protect sensitive surroundings: Do not spray near mulberry fields or aquaculture, or where bees, fish, livestock, game, wild birds
or animals could be harmed.
-
Measure and cover: Measure the treated area and the matching product and water amounts accurately. Use protective clothing, gloves
and eye/face protection and avoid spray drift.
