Diafenthiuron 50% WP is a thiourea-based insecticide and acaricide formulated as a wettable powder. It exhibits contact, systemic, and vapour action, effective against a wide range of sucking and chewing pests. Known for its delayed mortality effect, it inhibits mitochondrial respiration and chitin synthesis in insects, leading to eventual pest death and minimal resistance development.

It provides triple action — contact, systemic, and vapour — leading to prolonged control with reduced resistance risk.
Mortality is delayed by 24–48 hours, making it suitable for extended protection rather than knockdown.
Typically 250–500 g per acre, depending on crop and infestation stage.
Yes, COA, MSDS, bio-efficacy data, and regulatory compliance certificates are provided with bulk orders.
Handled in dust-proof WP/WDG lines with spray-dried suspension units and air-filtered packaging.
