PROBLEMS POTENTIALLY RESULTING FROM NEMATICIDE USE:

This table summarizes potential problems from the use or misuse of nematicides. Nematicides which have been found in groundwater in various situations include 1,2-dichloropropane (one of the components of D-D mixture), Vydate (oxamyl), Temik (aldicarb), and DBCP (dibromochloropropane). Telone II (1,3-dichloropropene) has been detected at parts per billion in California air which resulted in suspension of use for several years. Because of acute toxicity, the organophosphates and carbamates are considered to be more likely to cause harm to nontarget organisms and endangered species than are the fumigant nematicides. The carbamates and organophosphates also have greater potential for absorption by roots and thus to leave residues in food than do the fumigants. On the otherhand, several of the fumigant nematicides have been implicated as potential carcinogens.
