Best Control Methods of Sugarcane Borers
- CULTURAL CONTROL
- Sowing of clean seed of improved and tolerant sugarcane varieties.
- Strong earthing up.
- Balanced fertilization.
- Irrigation at 10 days interval during April-June
- Irrigation at 20 days interval during July-September.
- Harvesting of crop at ground level.
- Mechanical Control
- Rogueing of borer inested plants during April-September.
- Biological Control
- Release of parasite and predators i.e. Trichogramma @ 20000 to 40000 parasitized eggs per acre and Chrysoperla @ 1000 to 2000 parastized eggs per acre. These should be used at 10-15 days interval during March/April to October/November.
- Chemical Control
- Apply Furadan or Curator granules @ 1-2 gm on the cut base of rogued plant (dead heart) before irrigation and 8 Kg/acre to ratoon infested plant crop before earthing up during May/June.
Best Control Methods of Pyrilla
- Cultural Control
- Growing varieties with thin and erect leaves.
- Less ratooning.
- Trees, especially Poplar around/near the sugarcane field should not be grown.
- Avoid prolonged standing crop in the field.
- Mechanical
- Crusting of egg masses during April/May.
- Collection of nymphs/adult with hand nets and kill them.
- Burning of trash in the fields of severe infestation after harvest but leaving some in bundle nearby for the protection of natural enemies i.e. parasites and predators.
- Biological
- Release parasites/predators i.e. Epipyrops and Chrysoperla @ 1000 to 5000 per acre during April to September/October at 15 days interval.
- Chemical
- If needed, spray Lorsban 40 EC @ 1-2 liters per acre or Bifenthrin EC @ 250-500 ml per acre during April to September.
Best Control Methods of Termites
- Cultural Control
- Sugarcane should not be grown on elevated dry soils.
- More irrigation should be provided in termites infested area.
- Field should be ploughed deeply at least once before planting sugarcane
- Seed rate should be increased
- Poplar trees shouldn't be grown around and inside the field
- Uneven fields should be levelled.
- Channels should be dug out on the road and poplar sides and kept filled with water during the irrigation in summer months.
- Avoid the use of fresh farm yard manures
- Calotropic leaves/shoots etc. should be used in irrigaton water.
- Turmeric should be grown around the fields
- Chemical/Mechanical
- Lorsban 40EC @ 500 ml should be sprayed in furrows during planting burrying the cane setts especially in September plantation.
- Seed should be treated for half an hour in lime water prepared overnight.
- Seedlings should be treated with Lorsban or Tenakill or Talstar or Reagent EC in irrigation water.
- Swarming of a late reproductive form should be killed by light traps placed over poisoned water at dusk after rain in summer months.
- During swarming in July, the termites colonies should be traced out and destroyed it with Kerosine oil or insecticides.
- Wooden dry sticks/traps (1.5 ft) especially poplar should be fired or stacked around the field and termites collected be treated with insecticides and the sticks be installed again.
- It should be repeated once a week in summer months.
- Plastic traps should be used @ 12-16 per acre at distance of 10 meters in and around the fields.
- Holes should be dug out in fields at 5-10 meters and poisoned with insecticides once a month to poison the sub-soil.
- Copper sulphate @ 3-4 Kg per acre should be applied in irrigation water.
- Biological
- Aerial spray should be avoided for conservation of bio-control agents like lizards, toads and birds.
