Most herbicides sold in many chemical stores are expired, and mostly the seller always guarantees it will work.. You want to know if chemicals expired can it still work?

Why should you buy expired herbicide?

Return it fast. Why should he sell an expired chemical to you?

Yes it works, but not be effective as supposed.

Expiring date is sometimes useless when it comes to agrochemicals, however, you don't want to take a risk.

Return it would work but not be effective as supposed.
