DuPont™ Exirel™ and Verimark™ insect control: Novel insecticides for crop protection and optimizing yield in citrus in the United States

Exirel™ and Verimark™ insect control are novel insecticides based on the active ingredient Cyazypyr™ (DPX-HGW86, cyantraniliprole) that belong to the second anthranilic diamide insecticides discovered by DuPont™ .  Exirel™ and Verimark™ are the first products in its class of chemistry that control a cross-spectrum of insect pests including Lepidoptera, Dipteran leafminers, fruit flies, beetles, whiteflies, thrips, aphids, leafhoppers, psyllids and weevils, while conserving key predators and parasitoids.  Exirel™ and Verimark™  selectively activate the ryanodine receptor in insect muscles resulting in paralysis and rapid inhibition of feeding.  Exirel™ has been optimized for foliar use, demonstrating excellent translaminar movement.  Verimark™  has been optimized for soil applications to deliver consistent upward root systemicity.  Data on the efficacy of Exirel™ and Verimark™ on key citrus pests such as the Asian citrus psyllid, citrus leafminer and citrus thrips, including suppression of disease transmission and ultimately crop yield benefits will be discussed.
