Potassium chlorate as weedkiller?


I know in the past sodium chlorate has been sold as garden weedkiller, I am wondering if potassium chlorate would work as effectively?

I might mix some with water and a little detergent to break surface tension and help it to stick to the weeds.

It would work fine.
Since it's taken up by the roots there's not much to be said for adding a detergent.

You might want to check if it's legal...

sodium chlorate is sprayed on rice and soybeans as a "pre harvest dessicator". Will kill the shit outa weeds. BTW Wal-Mart sells it online........in the garden dept.

You will need to check that you can get enough into solution such that it will be at an effective concentration.

See attached.

*edit* it's approved as a pre harvest dessicant because it breaks down very quickly. Crop duster guy sprays, and three days later we're combining. Plants are dead and dry.

*edit* The "old farmers" refer to it as "salt" even though its CHLORATE not CHLORIDE.

Small note; in my youth sodium chlorate was the go-to weedkiller for domestic use
(or in my case, for pyrotechnics)
If used regulatly, unintentional application to wooden femces caused them to become incendary objects.
Later about 50% fire suppressants were added then later it was completely banned for retail in uk.
