Effect of split application of cadusafos and carbofuran on reproduction and fecundity of maize cyst nematode, Heterodera zeae and maize growth

A greenhouse experiment showed that cadusafos soil application @ 1 kg a.i./ha when applied either at the time of sowing or in the split dose was most effective than carbofuran in enhancing plant growth parameters of maize cv. Deccan-103 and reducing final population of maize cyst nematode, Heterodera zeae. The results further indicated that split dose of either of the chemicals given 21 days after nematode inoculation was comparatively less effective compared to their single doses. The fecundity of the nematode (eggs and J2 per cyst) was reduced maximum when cadusafos was applied @ 1 kg a.i./ha at the time of sowing as compared to all other treatments of carbofuran.
