PaanoMaiwasanangInsecticide Resistance…

  • Sundinangprinsepyong IPM
  • Gumamitngmaresistensyangbinhi
  • Sundinangprinsepyong GAP
  • Alaminang mode of action (MoA) ng insecticide products / brands
  • Pagpalit-palitinang Insecticide MoA group / Hindi langbasta Active Ingredient (AI) gayon din ang brands
