Considerations for pre-emergent herbicides with dry sowing

Given the dry start to the season in some regions, the question of how to optimise weed control and minimise crop effect when using pre-ems is pertinent.

 

In this webinar, we focus on what factors influence the residual control of weeds by pre-emergent herbicides with a focus on Trifluralin, Sakura and new-to-market herbicides.

Chris Davey, YPAG and WeedSmart Extension Agronomist and Mark Congreve, ICAN Senior Agronomist, assessed the sowing issues in South Australia and discussed strategies on using pre-emergents.

Factors covered include:

  • Soil type/texture
  • Rainfall forecast (after application)
  • Characteristics of the herbicide
  • Characteristics of the crop
  • Sowing time (tine vs disc) – sowing depth, speed, soil throw, stubble
  • Resistance status
