With the growing mushroom craze occurring worldwide, it’s no surprise that many people have taken to growing different types of fungi at their own homes.

As any mushroom grower quickly learns, though, contamination is just a part of the hobby, and will  eventually rear its ugly head while growing mushrooms at home. One of the most common contaminants that mushroom growers face is the Trich mold, commonly known as “Green Mold”. 

This article will provide you with all the information on Trich mold you need, such as what it is, what it does, how you can get rid of it, and a product that we love for reducing the likehood of contamination from Trich mold. Let’s get started:

What is Trich Mold?

Christiaan Persoon, a German scientist, discovered Trichoderma mold in 1794. It is currently  the most prevalent type of naturally occurring mold in various ecosystems across the world, and goes through a variety of growth stages.

This mold usually starts off as a white or off-white color, but as it matures and releases spores, it turns green. Wind, water, and insects are all propagation agents, which lend it to spreading quickly through the ecosystems it inhabits.

Though Trichoderma is commonly employed to create industrial and agricultural products, the fact is that you don’t want it growing in your garden or farm because of the dangers it poses to mushrooms and other plants.

Trichoderma also thrives in many types of climates and prefers moderate temperatures. It’s common in soil, but it’s also found on wood, drywall, wallpaper, various paper products, carpeting, and indoor textiles. Some species of Trich also have a pleasant, coconut-like smell. Their colonies also grow quickly, often maturing in just five days.

Negative Effects of Trich Mold

Trich molds are a major issue in the production of other edible fungi, such as oyster mushrooms (Pleurotus species) and shiitake mushrooms (Lentinula edodes). When mushroom substrates are contaminated with green mold spores, the mushroom mycelium is quickly subdued in the fight for nutritional resources. This makes the affected fruit bodies become spotted and unbuyable.

This mold is so aggressive, in fact, that T. Aggressivum F. Europeum, a European variant of this mold, has been responsible for substantial crop losses in the United Kingdom, while T. Aggressivum A. Aggressivum, a North American sub-specie, has caused severe crop losses in the United States and is still a threat to the UK.

Trichoderma doesn’t just affect plants and the economic viability of agricultural produce, either. It can also affect human and animal health. Individuals with weakened immune systems stand a higher risk of contracting diseases from Trich mold, but any individual who comes into contact with its spores has the ability to become sick.

Coughing, sneezing, sore throats, and asthma are all indications of exposure to its spores, which can cause lung illness. Trichoderma exposure can also cause an allergic reaction, which can involve everything from breathing problems to skin problems like a rash or hives.Trichoderma longibrachiatum, is a particularly harmful sub-species since it is resistant to antifungal medicines.

The Institute of Medicine (IOM) concluded in a 2004 study that there was sufficient evidence to support the link between indoor mold and respiratory tract illnesses. Furthermore, some evidence relating respiratory illness to mold exposure in otherwise healthy children is mentioned in the paper. Even healthy adults can begin to cough and wheeze after prolonged exposure to the green mold.

Green mold can also make pets sick, and since they are so small, they may get sick faster than adult humans when exposed to mold. Similarly, infants are more sensitive to mold-related sickness as well.

How to Get Rid of Trich Mold

The bad news is that once the mold turns green, its highly unlikely that you will be able to remediate it. Although we have had some success slowing down the progress of Trich by pouring salt on the affected area and soaking the salt with a bleach and water mixture, this was only a band-aid and the mold eventually came back with a vengeance.

With that said, the best way to get rid of Trich mold is to stop it from growing from the start. Luckily for those of us without a professional clean room, there there is a product that stops molds from growing in the first place. MGP Plus (formally Trich-Evict) is a substrate additive that not only inhibits the growth of molds, but it also adds additional micro-nutrients that increase grow speed, fruit production, and overall fruit size. It’s so effective, in fact, that of the thousands of reviews, the most notable are of those growers who report multiple, prolific flushes with record sized.

The best part is that there are no dangerous pesticides, herbicides, or chemicals in MGP Plus. It’s made from natural bacterial compounds that work to improve growing conditions for your mushrooms.

MGP Plus works to eliminate existing Trichoderma mold and prevent new Trich growth by adding nutrients to your mushrooms soil that is normally found in the wild but not in conventional store-bought or home made growing substrates.

This works to do two things:

  1. The extra nutrients help your mushrooms to grow faster and more abundantly, as well as increases their overall size
  2. The additional nutrients also prevent and eliminate Trichoderma mold by creating conditions that aren’t conducive to its growth.

If you’re dealing with Trichoderma mold on your mushrooms or want to prevent it from the get-go, we highly recommend trying MGP Plus on your next grow. We know it’s worked GREAT for us, and we’re confident it can do the same for you.
