Just-the-Trich – for Severe Trichoderma Incursions


This 6G blend is exclusively focused on the treatment of aggressive Trichoderma Harzianum presence in mushroom cultivation environments along with other common bacterial and fungal contamination types. This particular blend cuts the incursion of Trichoderma on cakes down drastically – an effect that amplifies over time as fewer spores are released into the environment.

This blend does not increase fruiting productivity – in fact, you will see a reduction in fresh weight somewhere between 10-30% over a healthy, non-contaminated substrate. This blend is intended for those who wish to treat Trichoderma incursion that appears during or before the first flush.  Trichoderma is a nuisance to deal with, and unfortunately, severe trich incursions require severe treatments. This blend is, however, 100% natural and USDA sanctioned for use with food-stuffs – there are no chemicals utilized to drive efficacy.

Just-the-Trich can be used in the following ways:

Substrate Spray: Simply add 2G to a 1L bottle, and spray your substrate when spawning to bulk, repeat weekly.

Tent Spray: The same as the substrate spray, only you spray the inside of your tent or fruiting chamber to proactively treat Trichoderma in the growing environment itself.

Viability/Best Before:
One 6G pouch will make 3 L of solution that will stay viable in an aqueous solution for up to a year when kept out of direct sunlight and in a cool environment.

Contaminant Protection Offered:
Blight and Fruit Rot (Alternaria spp.); Bacterial Blast, Blight, and Streak (Pseudomonas syringae, Bread Mold (Neurospora.); Black Mold (Aspergillus.); Pseudomonas viridiflava, Xanthomonas Spp.); Bacterial Fruit blotch (Acidovorax avenaesubsp); Trichoderma Harzianum; Sooty mold; Sour Rot; Southern Blight (Scerotium rolfsii); Sheath Spot and Blight (Rhizoctonia oryzae); White Mold (Sclerotinia sclerotiorum); White Rot (Scerotium cepivorum.)

Usage Guide

Using DRmyc products is really a straight-forward process, but it is important that instructions are followed for best results. If too few microbes are present on your mycelial cake, contaminants such as Trichoderma Harzianum and bacteria may still thrive, wreaking havoc on your substrate – just the right amount, and you’ll see a concurrent increase in yields and decrease in contaminants:

Mixing Instructions:

  • Step One: Purchase one of our MGP or Contam Reducing blends, if you haven’t already (if you have, thank you very much for your business)
  • Step Two: Get a scale – if you have one already, great. Measure out 2G of formula. If you don’t have a scale, but want to proceed, you may use 1/2 a teaspoon. It is best to sanitize the teaspoon with 70% Isopropyl Alcohol before use. Be sure to reseal your pouch, and place it in a cool place out of direct sunlight.
  • Step Three: Add 2G of the formula into a sprayer bottle. Robust, cleaning style sprayers work better with the added matter.
  • Step Four: Add either Reverse Osmosis or Mineral Water to your sprayer bottle. Do not use chlorinated tap water. Once full, shake and apply as needed.

Application Instructions:

  • Step One: Spray twice inside of tray, grow bag, or whatever surface your bulk substrate is coming into contact with. Ensure spray is done evenly across the surface.
  • Step Two: Add your bulk substrate + spawn to the tray. Ensure it is properly cooled to below 110*F. Once substrate is added, spray four-times (for a 400G substrate) – or 1 additional spray per additional 100G of substrate. Mix substrate together using sanitary practices (surgical gloves).
  • Step Three: Once the substrate is mixed, and the top surface is in its final position, spray the top surface twice. Ensure even spread across the surface of the substrate.
  • Step Four: Cover the substrate, and then place in your incubator at between 80-86 degrees Fahrenheit.
  • Step Five: Do not disturb your substrate until the 7th day. Forget it even exists.  On the 7th day, check your pan – you may find your substrate is ready to place into the fruiting chamber. After this step, continue as you normally would and reap the benefits of a bountiful harvest!
