Effectiveness of Chemicals against Heterodera Avenae Woll. on Wheat

Carbofuran, both flowable and granular formulations, was effective in reducing nematode population and increasing wheat yield in comparision to other chemicals. Isofenphos was phytotoxic, at the tried doses, but was effective in checking nematode multiplication. Different doses of aldicarb and phenamiphos, when tried with different nitrogen levels, behaved similarly as far as wheat yield and reduction in nematode population was concerned and were better than check treatment.
