| dc.description.abstract | In a field experiment conducted in the red soil of Agricultural College Farm, Vellayani applying thimet, disulfotan, rnephosfolan and carbofuron granules at three different levels, applied at the' time of sowing, disulfoton at 1 kgai/ha was found an effective and economic method for controlling pea aphid upto 5 weeks after sowing. In another field experiment it was observed that spraying of different insecticides commencing from the time of flowering along with one application of disulfotan granules at the rate of 1 kg ai/ha at the time of sowing reduced the incidence of pea aphid and pod borers and increased the yield significantly. On a benefit cost ratio basis the effective insecticides could be ranked as follows: f enithion >f enitrothion > monocrotophos > carbaryl > phosalone > quinalphos. | en_US |
