I have one hundred questions so I'll number a few to start with. 1. I understand how IGR's (insect growth regulators) work. It is basically just a synthetic juvenile horomone mimic that keep insects in there juvenile stages. Is that how pgr's work??? 2. What kind of applications are used on turf and other plants? Liquid systemic? Pelletized and taken through the roots? 3. What is the environmental impact of pgr's in general...I am assuming they are toxic. 4. Do gardener's use pgr's on anything other than turf??? bonsai tree's? Food crops? 5. Can someone point me to a good source of info on the subject?
