A replacement for Isotox
Two decades back, all I needed was two insecticides; Malathion for safe use and Isotox for a good kill. Malation is still sold(just bought some) but Isotox is off the shelves.
Isotox was great, you could use it like a contact spray and the residue on the plant gets absorbed and becomes a systemic or you could drench the soil with it for deep tissue absorption.
What affordable systemic is out there that can replace Isotox?
