Affects are worse when applied to crops suffering stress such as frost, cold wet conditions, or high temperatures soon after spraying. Some lentil varieties are more sensitive than others. Do not apply to Northfield variety. Preliminary results show  may be more sensitive than Nugget to label application rates.

White/yellow spots/bands may develop within three to four days after application (two days in bright sunny weather).

Lentil plants turn light green and whole leaves turn yellow to cream colour.

Effects disappear as new growth develops with no long term effects.
