Alternatives to methyl bromide for root knot nematode management on cucumber in Lebanon

Abstract

An experiment to compare nematode management tactics was conducted in South Lebanon on cucumber in commercial greenhouses naturally infested with the root-knot nematodes Meloidogyne incognita and M. javanica. Significant increases in fruit yield and a reduction of root galling index and nematode juveniles in soil were observed in plots following soil solarization for 50 days, and in plots treated with methyl bromide. The use of bio-rational products containing naturally occurring agents with putative activity against nematodes (Bio-Act, Bio-Zymes and Sincocin) were ineffective in our tests, nor did these products enhance the efficacy of soil solarization.
