Dipropalin is a preëmergent dinitroaniline herbicide. It is currenctly not commercially used in western countries,^[1] but may be available in China^[2]^{[unreliable source?]} and used in India.^[3] It has low acute toxicity.^[1] It is used on turf.^[1] Tests in the 1960s in the USA evaluated its performance as a trifluralin analog, where it scored the highest pre-emergent effectiveness amongst methyl-group analogs, though losing to several trifluoromethyls, such as trifluralin itself. Dipropalin's methyl group does see increased post-emergent activity, but no trifluralin analog was effective in this regard.^[4]
