Chlornidine is a preemergent herbicide. It is a dinitroaniline used in China^[3] and India^[4] on soybeans, corn, cotton, sorghum, and peanuts.^[1]

Not to be confused with clonidine, a drug.

It is similar to other dinitroanilines and inhibits the emergence of soybeans less than any other dinitroaniline, though it had unimpressive control of velvet-leaf and giant foxtail.^[5]

Chlornidine shares the same mode of action as other dinitroaniline herbicides such as trifluralin (see there for a detailed explanation) which involves inhibition and depolymerization of microtubule formation, effectively preventing germinating seeds' cell division.^[6]

It has been manufactured by Ansul.^[2]

Chlornidine in soil has a halflife of about 4 months, or 7 inside a greenhouse. The longer life is due to slower plant metabolism and less ventilation in the greenhouse.^[7]
