RAINFED RICE A SOURCEBOOK OF BEST PRACTICE AND STRATEGIES IN INDIA
Rice hispa
Use mechanical control with kerosene-dipped
rope.
Spray endosulphan 35EC at 1.0l/ha,
quinolphos 25EC at 1.25l/ha or
monocrotophos 36EC at 1.0l/ha at ETL of one
damaged leaf/hill.
Armyworm and climbing cutworm
Do not allow the field to be dried.
Keep the water impounded at flowering stage.
At ETL of one to two damaged leaves/sq m
crop area, spray the crop alternatively with
carbaryl 50EC at 2.5 kg/ha or malathion 50EC
at 1.125l/ha or dust the crop with methyl
parathion 1.5% or malathion 5% at 25 kg/ha.
Gundhi bug
Trim bunds and keep field weed-free.
Do summer ploughing.
Grow pigeonpea on bunds.
At the estimated threshold level of two to three
nymphs or adults/hill, dust the crop with
carbaryl 4%, malathion 5%, phenthoate 2%,
methyl parathion 1.5% or quinolphos 1.5% at
25-37.5 kg/ha.
Use varieties with multiple resistance in pest-endemic areas such as Sunahsha,
Shaktiman, Lalat, Rasmi, Samlei, IR36, Swarnadhan, Mahamaya, Rajdhan,
Vikramarya and Nidhi.
Do not destroy natural enemies such as predators and parasitoids; use selective
pesticides.
Do not destroy useful fungi, bacteria and viruses; use selective fungicides.
Do not use more than the recommended dose of nitrogen to avoid severity of pests
and diseases.
Do summer ploughing.
Give emphasis to biopesticides.
