Dual Active Chemistry and Complementary Modes of Action
Voliam Flexi combines two distinct chemical modes of action: Chlorantraniliprole belongs to the anthranilic diamide class (IRAC Group 28 - Ryanodine receptor modulators), which stimulates uncontrolled calcium release in muscle cells, causing rapid feeding cessation and muscle paralysis.
Thiamethoxam belongs to the neonicotinoid class (IRAC Group 4A - Nicotinic acetylcholine receptor modulators), which interferes with nerve signal transmission in sucking pests. This dual mode provides both caterpillar borer defense and systemic sucking pest suppression.
- Complementary Dual Spectrum: Simultaneous control over chewing caterpillars and phloem-feeding sucking insects.
- Systemic & Translaminar Translocation: Rapidly absorbed and distributed acropetally to protect newly expanding leaves and shoots.
- Suspension Concentrate (SC): Liquid formulation that blends easily with water for hydraulic knapsack spraying.
Target Insect Pests and Labeled Crops
Voliam Flexi is officially registered under CIBRC standards for managing mixed insect pest complexes in cotton, vegetables, pulses, and sugarcane. In cotton, it manages bollworms (Helicoverpa and Spodoptera) alongside whiteflies, jassids, and aphids.
In tomato and solanaceous vegetables, it protects against fruit borers and whiteflies that transmit leaf curl viruses, while in sugarcane, it curbs early shoot borer infestations.
- Cotton Defense: Simultaneous control over bollworm complexes and virus-vector sucking pests.
- Vegetable Protection: Controls fruit and shoot borers alongside aphids and whiteflies.
- Sugarcane Health: Suppresses early shoot borer attacks that stunt early cane tillering.
Application Guidelines and Resistance Stewardship
Apply Voliam Flexi at early pest infestation when caterpillar egg hatching occurs or sucking pest populations cross economic threshold levels. Ensure thorough canopy wetting using calibrated hollow cone nozzles on knapsack sprayers.
To prevent chemical resistance, rotate Voliam Flexi with insecticides featuring distinct modes of action (such as spinosyns, avermectins, or oxadiazines) within the cropping calendar.
- Early Timing: Spray during early larval instars before caterpillars bore inside fruits or bolls.
- Coverage: Use adequate water volume to ensure thorough penetration of dense foliage.
- Pre-Harvest Interval (PHI): Adhere strictly to the harvest waiting period indicated on the approved product label.

Common questions
What is the technical composition of Voliam Flexi?
Voliam Flexi contains Chlorantraniliprole 17.5% + Thiamethoxam 17.5% SC (Suspension Concentrate).
How does Voliam Flexi protect crops against both chewing and sucking pests?
Chlorantraniliprole stops caterpillar muscle contractions (diamide), while Thiamethoxam blocks nerve transmissions in sucking pests (neonicotinoid).
Which major pests does Voliam Flexi control in cotton?
It controls bollworm complexes (American and spotted bollworms) alongside sucking pests including whiteflies, aphids, and jassids.
