Dipropalin

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?]

[3] It has low acute toxicity.

[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.
