Weed management Systems in Field Crops

  1. 1. WEED MANAGEMENT SYSTEMS FOR FIELD CROPS Presented to Prof Dr. Nazim Hussain Sir Hamid Nawaz DEPARTMENT OF AGRONOMY
  2. 2. Outline  Weed Management  Weed Management Systems  WMS in Field Crops  Small Grain Crops  Row Crops  Preventive Control  Mechanical Control  Cultural Control  Biological Control  Chemical Control
  3. 3. Weed Management ..? “An environmentally sound system of farming using all available knowledge and tools to produce crops free of economically damaging, competitive vegetation.”
  4. 4. Weed Management Systems A) Small Grain Crops B) Row Crops C) Turf D) Pasture & Rangelands E) Perennial Crops F) Aquatic Weed Sites Field Crops
  5. 5. Weed Management Systems for Crops Small Grain Crops Row Crops
  6. 6. Preventive Mechanical Biological Cultural WEED
  7. 7. Weed Management System Prevention  Weed Free Crop Seeds.  Weed Free Manures.  Clean Harvesting equipments.  Elimination of Weed infestation in irrigation water.
  8. 8. Mechanical (Small Grain Crops)
  9. 9. Mechanical (Row Crops)
  10. 10. Cultural Control  Crop selection  Rotation  Variety selection  Planting date  Plant population  Spacing  Fertility Manipulation  Mulching
  11. 11. Mulching for weed Control Mulches stop weed growth: By restricting the penetration of sunlight to the soil surface By Releasing Allelopathic Chemicals. Reduce the germination of weed seeds
  12. 12. Biological Control “Use of living organism’s viz., insects, disease organisms, herbivorous fish, snails or even competitive plants for the control of weeds is called biological control.”
  13. 13. Chemical Control There are 4 types of herbicides: Broad Spectrum - these work on a wide variety of weeds. Selective - these work on a narrow range of weeds. Contact - these destroy weed tissue at or near the point of contact (they do not spread around the weed), and require even coverage in their application. Systemic - these move through the weed's circulation system, and can be injected into the weed.
