Dipropalin
Dipropalin is a preëmergent dinitroaniline herbicide. It is currenctly not commercially used in western countries, but may be available in China and used in India. It has low acute toxicity. It is used on turf. 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.
