The biocidal activity of THP (tetrakis hydroxymethyl phosphonium) compounds is synergistically enhanced by using them in conjunction with wetting agents.

Biocidal mixture of tetrakis (hydroxymethyl) phosphonium salt and a

Phosphonium salts such as THP and aldehydes such as formaldehyde exhibit synergistic biocidal activity.

Biocidal compositions and treatments

A method for protecting growing plants against fungal or microbial plant pathogens which comprises applying thereto, or to the medium on which they are growing or to be grown, a composition comprising a water soluble tetrakis (hydroxymethyl) phosphonium salt.

Method for protecting growing plants against fungal or microbial path

Solutions of organophosphorus biocides which also contain dissolved oxygen are deactivated by adding a catalytic amount of activated carbon.

Deactivation of phosphonium biocides

A method of treating surfaces colonized or colonizable by bryophites or lichens which comprises applying thereto sufficient of a water soluble tetrakis (hydroxymethyl) phosphonium salt to kill, or inhibit the growth thereon of said bryophytes or lichens.
