Summer herbicide trials on prickly lettuce 2015–16 locations
Aims

These two experiments aimed to evaluate a range of herbicides with different modes of action on prickly lettuce control, and to evaluate if a ‘double-knockdown’ technique is needed to effectively control mature prickly lettuce.

Key messages
  • After stem elongation, mature prickly lettuce plants are difficult to control.
  • Controlling mature prickly lettuce plants early achieves better results.
  • No single treatments, except paraquat, achieved 100% control of mature prickly lettuce plants that emerged after a wheat crop was harvested. The paraquat, either used alone or as a follow-up application, was the only outstanding treatment, achieving 100% control.
