Yes
Minor Pest Title: 

Cutworms (Agrotis spp. and other species)

Minor Pest Description: 

Cutworms cut maize seedlings at or a little below ground level, make small holes along the initial leaves, or remove sections from the leaf margins.

 

Minor Pest What to do.: 
  • Eliminate weeds early, at least 2 weeks before transplanting.
  • Plough and harrow the field prior to transplanting. This exposes cutworms to natural enemies and desiccation and helps destroy plant residue that could harbour cutworms.
  • Make barriers to protect the transplanted seedlings. Barriers can be made by wrapping paper, aluminium foil, thin cardboard or similar materials around the base of transplant stems. Toilet rolls are handy as cutworm collars since they are readily available and will biodegrade into the soil.
  • Dig near damaged seedlings and destroy cutworms.
  • Conserve natural enemies. Parasitic wasps and ants are important in natural control of cutworms.
