To protect your valuable crops from whiteflies and the damage and viruses they can vector, you need Knack® Insect Growth Regulator. This impressive IGR provides unmatched control of sweet potato and silverleaf whiteflies in cotton, tomatoes, peppers, brassica leafy vegetables and cucurbits. Knack has translaminar activity, so it reaches whiteflies where they feed – under the leaf – and delivers long-lasting control. Plus, its highly targeted soft chemistry is a good fit for Integrated Pest Management (IPM) and Insect Resistance Management (IRM) programs.
