Sporekill (PCS No.92396) is another product where the active ingredient is based on potassium salts of fatty acids. It is fully registered as a PPP for use on mushroom crops. Recently, the registration label has been extended to include new uses including crate washing and disinfestation (fly control).

For flies, it can be applied by spray on walls and door/frames or by fogging the growing room after filling. It works by direct contact, disrupting cell membranes so flies dehydrate and are eliminated.

Fogging with Sporekill should also help knock down spores that have entered during filling, encapsulating them and rendering them non viable so fogging is a practice against pests and diseases at the start of a crop.

Refer to the product label for further information.

We are excited to announce that we recently submitted and tested Sporekill Spot against Coronavirus C19 in a specialist lab and the results came back with a log 4.2 reduction. This means a 99.99% reduction ie total control.

The lab report is on the Home page.Testing was carried out to BS EN 14476:2013+A2:2019. This European Standard specifies a test method and the minimum requirements for virucidal activity of chemical disinfectant and antiseptic products.

We believe that mushroom farms would therefore find it be to be a very useful product around picking and personnel areas. It dries quickly due to the ethanol base.

Just to be clear, the C19 product is the Spot Treatment version of Sporekill which some of you may not have used before. It is what growers use for spot treatment of disease on the casing surface as a substitute for salt in Organic farms. It uses an ethanol carrier as opposed to water as a co formulant, which allows quick penetration on surface right down the root and evaporates off leaving the residual protection of Sporekill itself.

It is currently available in 20L drums and 1000L IBCs and we are working on a box which will contain 500 or 750ml spray bottles ready to use.
