## Overview

MGP Plus by DRMyc is a 100% organic mushroom substrate probiotic powder that accelerates colonization speed by 30-50%, boosts yields and fruit size, and naturally suppresses contaminants like Trichoderma. Featuring nitrogen-fixing bacteria and a proprietary PGPR blend, it enriches substrates without chemical fertilizers or pesticides. Trusted by over 5,000 users across three countries, MGP Plus is your go-to growth promoter for gourmet and medicinal mushrooms.

## Description

With the use of DRMyc's substrate probiotic - MGP Plus (formerly TrichEVICT) - you can expect substantially larger gourmet/medicinal mushroom yields expect them days ahead of schedule. This is thanks to our 100% organic, proprietary PGPR (plant growth-promoting rhizobacteria) blend. Through heightened nutrient competition, MGP Plus also broadly prevents incursions of common contaminants such as Trichoderma (green mold) and Pseudomonas tolaasii (bacterial blotch) on your fruit bodies and substrate - without the use of chemical pesticides. With MGP or TrichEVICT, multiple bacteria species function together synergistically to produce favorable metabolites and release nutrients through microbial mineralization. One of the species, Azospirillum, a free-living nitrogen-fixing bacterium, also fixes atmospheric nitrogen for uptake - turning a non-nitrogen-rich substrate into a much richer nutritional growing environment similar to manure. While supplementary nitrogen and other available nutrients ensure your mushrooms have every chance to have strong cell walls and grow to be big and healthy, the real growth promotion benefits come from the secretion of metabolites which spur on growth. MGP Plus contains no nitrates, no added phosphates, and no chemical pesticides. Simple to use, just mix MGP Plus with non-chlorinated water of your choice and spray your substrate to amend it with natures' finest microbes. By using DRMyc's substrate probiotics, you create an ideal environment for mushroom cultivation with increased nutrient competition for contaminants such as Trichoderma, Wet Rod,.

## Questions & Answers

**Q: Can I add this product to my grain before spawn or should I use magical gypsum for that?**
A: Hello Billy,
You should use Magical Gypsum for that, but you can add a bit more MGP + to your grainsoak to get maximum effects from it. Add it to your grains, along with room temperature water (de-chlorinated if possible) for 24 hours, then PC as normal. You'll notice much faster colonization and less contamination (assuming this was an issue).
Thanks for your business,
John (DRMyc)

**Q: Will this survive pressure cooker/autoclave?**
A: Hello Shaun, MGP Plus will not survive the Autoclave, but you can  use it as a grain additive in during your grain soak. This way, the microbes will enter their exponential growth phase with the grains, perform microbial mineralization & secrete their MGP's which survive the temp & pressure of the PC. This will give your grains a head start, but there will be no microbes that survive the PC - so you will have to reapply when S2B.
Thanks,
John (DrMyc)

**Q: Will this product work with 
Brown rice ?**
A: Yes, MGP and MGP + will work with brown rice. Many of the microbes are Bacillus and are ideally suited to brown rice - those using either of our MGP formulas with BRF cakes have seen very good results.
