IPM Crop Monitoring and Spraying

  • Walk forage brassica crops regularly from early emergence 
  • Identify and monitor both the pests present AND their natural enemies 
  • Gauge the degree of crop damage against the balance between pests and natural enemies before determining the need to spray 
  • For key pests, use an IPM-compatible insecticide such as Sparta & Transform.

 

Principles of Weed Control

The goal is to:

1. Reduce weed competition within the brassica crop.

  • Protection of crop from emergence through to canopy closure.
  • Reduce any competition of light, water, nutrients etc.
  • High weed population and a poor crop at grazing results in reduced yield and quality.

2. Reduce weed competition in a crop/pasture rotation.

  • Reducing weed seeds within the soil.
  • Good control of perennial and rhizomatous weeds.
  • ➢ E.g. Californian thistles, Yarrow, Dock.

 

Key considerations:

1. Establishing a dense crop canopy is one of the most effective control methods.

  • Target rapid crop emergence, growth and establishment.
  • Achieved through pH, fertility, seedbed preparation, accurate planting depth & seed to soil contact.
  • Herbicides help to bridge the gap.

2. In dry soils or seasons. Forage brassicas are more prone to split germination.

  • Post-em herbicide timing should be based on stage of weed growth, not the crop stage.
  • Post-em herbicides for forage brassica must be safe over germinating seedlings & cotyledons.

3. Opportunities around targeting both weeds and pests at the same time.

  • In these situations, timing should be according to the earliest treatment required.
  • Don’t delay & compromise optimal control of one.
  • E.g. if weeds are ready to be sprayed, don’t delay for insects, & vice versa
