PEST MANAGEMENT ADVISORIES

Rodent

During fallow period

  • Community Trap Barrier System

Before seed sowing

  • Chemical control
    • Acute rodenticide = Pre-baiting: before seeding or before transplanting -use acute (single-dose) poison
      • Zinc phosphide
      •   Chronic rodenticide = 2 WAT: 5 baiting stations/ha (6 tbsp./station) use chronic (multiple-dose)
        • -Coumatetralyl (Racumin)

During land preparation

  • Sanitation
  • Rat burrow management
  • Night rat hunting

Maximum tillering

  • Increase water level

Booting stage

  • Organize community wide rat hunting
  • Flooding
  • Use of flame thrower 
  • Use of trap 

 

Stemborer

Before sowing

ü  Thorough land preparation to kill larvae and pupae

ü  Plant rice varieties that are  moderately resistant to stem borer

ü  Practice synchronous planting- allows fewer stem borer generation within the cropping season-reducing damage.

At seedbed and transplanting

ü  Hand pick and destroy egg masses

ü  Raise water level periodically to submerge egg masses deposited on the lower parts of the plant.

ü  Before transplanting. Cut leaf-top to reduce carry-over of egg masses from seedbed to the field

ü  Follow recommended N fertilizer application. High N increases crop susceptibility to stem borers

After transplanting

ü  Field release of Trichogramma japonicum (egg parasitoid)

ü  Judicious application of insecticides

ü  Use insecticides as a last resort – and only when needed to conserve natural enemies

     (Larvae are inside the stem and eggs are minimally killed by insecticides)

 

 Tungro

ü  Synchronous planting (planting on same dates)

ü  Plant tungro or leafhopper resistant varieties

ü  Practice fallow (rest) period

ü  Seriously infected fields should be plowed under when severe symptoms appear

ü  Rogue or pull out diseased plants during the first 6 weeks of crop growth in slightly (3% or less) infected areas

ü  Remove weeds that look like alternative hosts because virus-infected hoppers breed in weedy areas

ü  Avoid excessive application of nitrogenous fertilizers

ü  Control the insect vector using biological control agents and chemical insecticide as last resort

 

Armyworm

Cultural Methods

ü  Practice fallow (rest) period of 2-3 months to break the life cycle of the pest

ü  Egg masses and larvae should be collected and crushed

ü  Remove alternate hosts

ü  Plow under plant debris after harvest

ü  Follow recommended fertilizer requirement

ü  Crop rotation with root crops, cotton and other non-graminae plants

ü  Lower plant population per hectare or increase planting distance to allow sunlight to penetrate

Biological Control

ü  Use of Biological Control Agents such as predators (spiders), parasitoids (wasps) and entomopathogens (NPV)

Chemical Control

Chemical control (use pyrethroids, methomyl, chlorpyrifos, triazophos insecticides)
