Integrated Pest Management and Weed Management

Integrated Pest Management

The integrated pest management (IPM) is a way to control unwanted bugs using techniques other than pesticides.

Some techniques include processes like the following:

  • Rotating crops in a given place so that bugs that attack certain plants are not constantly attracted to the same place.
  • Using non-harmful insects to eat the bad ones, like ladybugs to eat aphids.
  • Using physical barriers around the plants.                      Integrated Pest Management and Weed Management
  • Using baits or traps to attract the bugs to a different location.

Organic Pesticides 

Some of the common organic pesticides are as follows:

  1. Neem: Neem juice is the most powerful natural pesticide, holding over 50 natural insecticides. It can be used to make a natural pesticidal spray.
  2. Salt spray: For treating plants infested with spider mites, salt and water spray can be used on the infected areas.
  3. Mineral oil: Mixture of mineral oil and water can be used for dehydrating insects and their eggs.
  4. Citrus oil and cayenne pepper: This organic pesticide works well on ants.
  5. Eucalyptus oil: It is a great natural pesticide for flies, bees and wasps.
  6. Chrysanthemum flower: Chrysanthemum flowers possess a powerful plant chemical component called pyrethrum. This substance invades the nervous system of insects, rendering them immobile. Chrysanthemum flower is an effective organic pesticide.

Weed Management

  • Organic crop rotations frequently include weed-suppressive cover crops and crops with dissimilar life cycles to discourage weeds associated with a particular crop.
  • Other cultural practices that are used to enhance crop competitiveness and reduce weed pressure include selection of competitive crop varieties, high-density planting, tight row spacing and late planting into warm soil to encourage rapid crop germination.                  Integrated Pest Management and Weed Management

Mechanical and physical weed control practices used in organic farms can be broadly grouped as below:

  • Tillage: Turning the soil between inter-season crops to incorporate crop residues this removes existing weed growth and prepares a seedbed for planting new crop.
  • Mowing and cutting: Removing top growth of weeds.
  • Flame weeding and thermal weeding: Using heat to kill weeds.
  • Mulching: Blocking weed emergence with organic materials, plastic films, etc.

What Does Organic Farming Exclude?

  • Genetically modified seeds and animals
  • Nanomaterials
  • Human sewage sludge
  • Plant growth regulators and hormones
  • Antibiotic use in livestock husbandry.
