Certain esters of 1-hydroxy-cyclobutene-3,4-dione and mono- and diesters of square acid have been found to be useful in the regulation of plant growth, especially as post-emergent herbicides, as plant growth inhibitors and desiccants. New esters of this type and their manufacture are also described.

In the presence of thiophenols semisquaric hydrazides (4) are converted into squaric-1,2-diamides (6) upon heating in alcoholic solution. Proof is given that thiosquaric-S-ester-amides (8) are intermediates in this process.
