Select the nematicides group which are nonfumigant in nature

Aldicarb and Phorate are the nematicides group which are nonfumigant in nature.
Non-fumigant nematicides available for vegetable production in Florida include two broad categories, chemical nematicides, and biological nematicides.
Aldicarb is a carbamate insecticide that is the active substance in the pesticide Temik. It is effective against thrips, aphids, spider mites, lygus, fleahoppers, and leafminers, but is primarily used as a nematicide.
Phorate is an organophosphate used as an insecticide. It is very toxic both for target organisms and for mammals including humans.
