If needed, apply again in 10 to 14 days. Light leaf speckling may occur, but crop plants generally outgrow this condition within 10 days. Canada thistle must be thoroughly covered. Avoid applications during drought or unseasonably cold weather. Unsatisfactory results can be expected if daytime temperatures do not reach at least 70 o F during the week following application.
Maximum rate depends on crop.
The 2-quart rate can be used in fallow and in grass seed crops. The Canada thistle should be in the rosette to prebud stage of growth. Apply in warm weather when weeds are actively growing and soil moisture is adequate for active plant growth. Consult label for crop rotation restrictions before using product. Several crops may be injured up to 4 years after application.
