Abstract

The organo-phosphate experimental nematicide, O-ethyl S,S-di-sec-butyl phosphorodithioate (FMC 67825), provided yield increases of corn comparable to carbofuran. Both the emulsifiable concentrate and granular formulations of FMC 67825 were equally effective. The evaluations, duplicated in two adjacent fields, clearly demonstrated the importance of the type of plant pathogenic nematodes infesting the sites. Where Belonolaimus longicaudatus occurred, yield increases ranged from 73% to 80%, whereas in the adjacent field (without B. longicaudatus) yields increases ranged from - 14% to 28%. Key words: Belonolaimus, carbofuran, corn, Criconemella, FMC 67825, lesion nematode, Meloidogyne, nematicide, Paratrichodorus, Pratylenchus, ring nematode, root-knot nematode, sting nematode, stubby-root nematode, Zea mays.
