PEST MANAGEMENT DECISION GUIDE: GREEN AND YELLOW LIST

Tomato fruit borer

Helicoverpa armigera Hubner Loodi
India
  • Deep summer ploughing.
  • Early planting can help avoid this pest.
  • Avoid monocropping. Grow simultaneously 40 day-old African marigold with 25 day-old tomato seedlings, in the 1:16 rows.
  • Correctly space your seeds/seedlings. Spacing depends upon variety but in general should be 60 x 45 cm.
  • Install bird perches in the field to encourage predatory birds.
  • Avoid the use of broad spectrum insecticides to conserve natural pest enemies (such as spiders, ants, parasitic wasps and robber flies).
  • Regular monitoring of the crop to check for caterpillars on the leaves, ideally during morning and evening hours. Threshold is 5-10% of leaves infested.
  • Use pheromone and/or light traps to check for the presence of the adult moths. Use 1 trap per acre. Action threshold is 3 or more adult moths in a trap.
  • Install pheromomone traps (5 traps per acre) for mass trapping of male moths. Change the lure every 15 days.
  • Install light traps to attract and kill adult moths.
  • Release the egg parasitoid Trichogramma brassilences or T. pretiosum at a rate of 40000-60000 parasitoids per acre once the action threshold is reached, or at the time of flowering. Repeat at 15-day intervals.
  • Spray neem-based insecticides e.g. NSKE (5% or Neem oil at a rate of 3 ml/L of water).
  • Foliar spray of the virus HaNPV (250 LE/Ha) with 20 Jaggery in the evening hours.
  • Foliar spray of the bacterium Bacillus thuringiensis var. kurstaki (1-1.5 kg/Ha).
  • Follow pesticide rotation to avoid pest resistance
  • Frequency of spray depends upon the pest intensity
  • Use of personal protective equipment (PPE) is recommended while using chemical pesticides
  • Spray the crop with Spinosad 45 SC at a rate of 0.5 ml/L.
  • WHO Class III (slightly hazardous).
  • Spray with either of the following: Flubendamide 48 SC, Chlorantraniliprole 18.5%, Indoxacarb at 0.1% or HaNPV at 250 LE and a half dose of any of the aforementioned chemicals.
  • Flubendamide and Indoxacarb WHO Class II (moderately hazardous); Chlorantraniliprole WHO Class U (unlikely to present acute hazards in normal use).
