Recent data from a UK farm show significant improvements in yield going from normal 200ml/m² to 300ml/m².
On 3 flushes….
200ml 300ml Yield effect from 200 to 300
8224 8466 ↑ 0.9 kg/m²
7381 7866 ↑ 1.82 kg/m²
7120 7674 ↑ 2.08 kg/m²
On 2 flushes….
7100 7637 ↑ 0.9 kg/m²
A quality improvement (grade mix) was also reported with the higher rate.
OUR RECOMMENDATION is now 300ml/m²
Cooking out with steam still remains the safest option when emptying growing rooms. However you must bear in mind that steam will not get your floors to a high enough temperature to kill most mushroom pathogens, which means another strategy must be adopted.
One such strategy is using a tried and tested mushroom disinfectant like Sporekill (Nutriclean). It is ideal for cleaning growing rooms; floors, walls and shelving etc. It is, in our opinion, the best solution for floors because after disinfection action it leaves a odourless protective film over all the tiny cracks and holes on the floor surface, sealing any remaining spores and debris settling after filling of your rooms. This stops any disease becoming airborne again and leaves surfaces clean and safe for foot traffic and packaging bases.
Don’t just take our word for it….our customers are the proof, it’s a fact that once they start using it they rarely change back to any other disinfectant and your mushrooms will never have any unsafe residues in them.
We have made a new video presentation about our disinfectant to explain about its benefits in more detail.

These pictures were taken on a farm at the same time, from pinning through to 4th flush. There is no granular supplement in the compost, compost fill is 75kg/m². Yield in 3 flushes 29kg/m² and in 4 flushes 33kg/m². Note the mushroom shape and quality in all flushes, even later ones.
Please make sure after applying Mycrofeeder, that all equipment is flushed; tank, pipe and pumps with clean water and hypochlorite or Sporekill.
Concentrated feeder is safe from moulds, but diluted feeder can encourage their development.
“Consider what happens after a diseased crop is watered; pools of contaminated water collect on the floor and some at least will dry out. Sooner or later someone will walk on the floor and disturb debris and Verticillium spores lying on it.
Air sampling showed that it only required one person to walk down the central gangway of a cropping house with a clean dry concrete floor for the dust and spore content of the atmosphere to increase noticeably”

This type of spread can be prevented by sprinkling SPOREKILL on the floor.
One of the key benefits that our customers get when using Mycrofeeder is mushrooms staying immature for longer ie solid and closed even at the end of the flushes.
This is a time when a lot of extra weight can go into the mushrooms affecting final yield and picking rates.
When using Mycrofeeder, OBSERVE CLOSELY how the mushrooms grow out in terms of SHAPE and VEIL and you may find that you don’t have to PICK as TIGHTLY as you would normally at that moment.
During this Autumn we have continued to evaluate the dosage and water volume for application onto the compost surface at or after filling.
The Mycrofeeder rate remains at 200ml/m2 but the inclusive dosage of 2l /m2 (1.8L water, 0.2L feeder) can be reduced to a range of 1.5l /m2-1.3l /m2.
Substantially this is to help minimise the “ knockback “ effect during cooler and wetter conditions whilst maintaining the correct growth into the casing layer.
This also keeps dilution of the supplement at a high rate to maintain the correct feeding to the advancing mycelium and reduce the risk of delayed growth/timing.
Seasonal changes can have a deleterious effect on the cultural establishment during the Case run period in particular.
Both the compost and casing can be less active during the first 48hrs and should be given careful consideration as to whether adjustment to the normal programme may be required.
When mycelial recovery is compromised the weaker growth is not able to feed in an optimal manner which can limit crop potential and timing.
If too much free water remains at the interface under less active conditions it is possible to wash the supplement down into the compost below the target zone.
You should expect to see a more robust growth of mycelium developing at the interface when using the Mycrofeeder and the time of airing normal as planned.
Getting 23C or more on the interface for 2-3 days at the end of the case run/start of pinning remains vitally important.
It was pointed out to us recently from a long standing user of Sporekill, that he noticed when he took his boots off at the everyday, they were ‘sticky’ and ‘tacky’ on the soles. So the good news is that spores are going to get stuck to the soap matrix on the boots and not spread around the farm. Another great reason for using Sporekill in your footdips.
