Reemit 35 WSB is an Insect Growth Regulator (IGR) containing 35% pyriproxyfen. It works by suppressing embryogenesis within the insect egg and inhibiting metamorphosis and adult emergence of target insects. It is important to note that this product has no activity on adult insects, though it will suppress the hatching of eggs laid by treated adults. It is used for the control of various pests including Group 7 (Pome Fruit), Group 12 (Stone Fruit), and Group 14 (Tree Nuts) pests. Applications are primarily outdoor agricultural uses on various fruit and nut crops. The product is a wettable powder that must be mixed with water. Handling requires specific Personal Protective Equipment (PPE), including long-sleeved shirts, long pants, and socks plus shoes. Users should avoid contact with eyes and skin, and should wash hands thoroughly before eating, drinking, or smoking. The label provides extensive guidance on spray drift management, temperature/humidity considerations, and resistance management, recommending the use of integrated pest management (IPM) programs.
