Abstract Several fumigants,93% 1,3-dichloropropene EC,62% 1,3-dichloropropene capsule,42% metham sodium AS,98% dazomet MG,99% sulfuryl fluoride TC,93% 1,3-D EC+98% dazomet MG,and 93% 1,3-D EC+42% metham sodium AS,were used to control cucumber root-knot nematodes.98% Methyl bromide was used as control.The results showed that all fumigant treatments had good efficacy against root-knot nematodes.The cucumber yield from all fumigant treatments was higher than that of untreated control.The yield obtained by treatments of 50 g m-2 98% Methyl bromide,9 g m-2 93% 1,3-D EC+25 g m-2 98% dazomet MG and 9 g m-2 93% 1,3-D EC+21 g m-2 42% methm sodium AS were the higher than the control.Good yield and economic benefits can also be achieved,when cucumber is treated with fumigants 9~18 g m-2 1,3-D EC,1,3-D capsule and 25~50 g m-2 sulfuryl fluoride TC.
