Crystal Proclaim Xtra is an EC insecticide developed for maize and soybean farmers to help manage caterpillar pests, especially Spodoptera species such as fall armyworm. It combines Emamectin Benzoate and Lufenuron to act on caterpillars in more than one way.
With contact, systemic and translaminar action, Proclaim Xtra helps stop caterpillar feeding quickly after application. Its insect growth regulator action also disrupts insect development, helping reduce the build-up of the next damaging stage.

Emamectin Benzoate acts on the nervous system of caterpillars by activating chloride channels, which causes paralysis and stops feeding. Lufenuron inhibits chitin formation, so larvae cannot moult properly and fail to develop into the next stage. Together, they provide both quick knockdown and longer-lasting control.
Proclaim Xtra gives maize and soybean farmers a two-way approach to caterpillar management, combining fast feeding stop with growth regulation. It is a useful option for fall armyworm and Spodoptera management and for rotating with insecticides from other groups.
