The 'Biology-First' IPM: How to Stop Reacting and Start Installing Disease Defense
By Jeremy Standring
If you’ve been growing hemp or vegetables for more than a single season: especially here in Zone 6: you know the feeling. You walk into the field or the greenhouse, the coffee is still hot in your hand, and there it is. A spot of Powdery Mildew. A fuzzy patch of Botrytis.
Suddenly, your day changes. You’re not a grower anymore; you’re a firefighter. You go grab the heaviest "organic-approved" fungicide you have, you spray, and you hope for the best. Sometimes you win the battle, but you’re losing the war because you’re always a step behind.
At Regen Soil, we’ve spent years trying to break that cycle. What I’ve realized is that most Integrated Pest Management (IPM) programs fail because they are reactive. We wait for the problem to show up, then we try to kill it.
I decided to stop trying to "kill" disease and started focusing on installing biology.
The Shift: From Reaction to Installation
Biologicals get a bad rap in some circles. People say they "don't work" as well as conventional chemicals. But here’s the truth: Biologicals aren’t weaker than conventional inputs; they’re just system-dependent. If you try to use beneficial soil microbes reactively, they’ll disappoint you every time. They aren't "knock-down" agents.
Think of it like software. You don’t wait for a virus to delete your files before you install antivirus software. You install the software first so the virus never has an opportunity to establish.
In our RSI Method, we don't just "spray for disease." We occupy the ecological space on the leaf surface and in the rhizosphere before pathogens ever get a chance to take hold. If the "good guys" are already living there, there’s no room for the "bad guys" to move in.
The Foundation: High Microbial Compost Teas
The system fails if the foundation is weak. For us, that foundation isn't something you buy in a bottle: it’s something we build.
I make my own thermophilic compost. This isn't your average backyard pile; it’s a managed, high-temperature process that cycles nutrients and breeds a massive diversity of soil microbiology. From this compost, we brew microbial-rich teas and extracts.
Why compost tea? Because it’s a living delivery system. When we apply these extracts, we are flooding the plant with a diverse community of organisms that have been "trained" in a high-energy environment. This is the base layer of our IPM.
If you're unsure where your soil biology currently stands, an Initial Soil Health Assessment is usually the best place to start. You can't manage what you haven't measured.
The Enhancers: Diversity and Activity
Once we have our base tea, we "supercharge" it. Diversity is the key to resilience. If you only have one type of beneficial microbe, a single environmental shift can wipe out your entire defense. We want a microbial "Special Forces" unit.
We enhance our extracts with two specific heavy hitters:
- Xtreme Garden Bacillus Blend: This adds a concentrated punch of Bacillus species known for their ability to colonize roots and leaves, producing natural compounds that inhibit pathogen growth.
- TerraBiotics Ultra Bio-Boost: This is a prebiotic and probiotic microbe package delivering over 570,000,000 cfu/gram, which is the highest on the market. It includes 20+ strains of bacteria, 9 strains of mycorrhizae, and 3 strains of Trichoderma, giving us a broad-spectrum biology package that supports nutrient mobility for Nitrogen, Phosphate, and Potassium while also strengthening root health. In our system, TerraBiotics Ultra Bio-Boost is not just a supplement or an add-on. It acts as a key engine in the biology-first system by helping microbial populations establish, multiply, and stay active where they matter most.
By combining these, we aren't just adding microbes; we’re ensuring they have the numbers, diversity, and biological energy to dominate the environment.
The Support Layers: BioWorks Cease and MilStop
Now, we layer on the professional-grade tools. Notice I said "layer on." These are not the foundation; they are the support.
- CEASE: This is a biological fungicide based on Bacillus subtilis. It helps drive biological activity and triggers the plant's own systemic acquired resistance (SAR). It’s like giving the plant’s immune system a pep talk.
- MilStop SP: This is a potassium bicarbonate-based foliar fungicide. It provides targeted suppression. If we see a spike in humidity or a sudden increase in disease pressure, MilStop is our tactical tool to knock back any spores that might be trying to germinate.
When these are used in conjunction with a living biological base, the level of consistency is incredible. We’ve seen this protocol work across multiple seasons and different sites in hemp and vegetable systems without a single economically significant outbreak.
The Protocol: Root Drench and Foliar Application
You can’t just hit one part of the plant and expect total protection. We hit both sides of the system.
We apply our biological "cocktail" as both a root drench and a foliar spray.
- Root Drench: This builds the Rhizo Logic in the soil, ensuring the plant has a strong "gut" and can uptake nutrients efficiently while resisting soil-borne pathogens.
- Foliar Spray: This coats the leaves, stems, and flowers in a protective microbial film.
The Timeline: We start at the seedling stage. If you wait until the plant is in mid-bloom to start your IPM, you’ve already lost the most important window. We stay consistent from those first true leaves all the way through the last week of harvest.
The Golden Rules of Biology-First IPM
If you take nothing else away from this, remember these three rules. This is where most growers trip up:
1. Timing > Product
It doesn't matter if you have the most expensive, high-tech biological on the planet. If you apply it after the disease has already colonized the vascular system of the plant, it’s too late. The "when" is infinitely more important than the "what."
2. Coverage > Concentration
Biology is a numbers game. You need the beneficials to be everywhere the pathogens want to be. This means getting into the under-canopy, hitting the undersides of leaves, and ensuring the root zone is thoroughly saturated. A lower concentration with perfect coverage will beat a high concentration with poor coverage every time.
3. Consistency > Everything
This is a system, not a one-time event. If you skip a week because "the plants look fine," you are creating a window of opportunity. Regenerative farming practices rely on the momentum of biological populations. Once that momentum drops, it takes a lot of work to get it back.
Why This Matters for Hemp and Vegetable Growers
In Zone 6, we deal with wild swings. We have humid summers that are basically a playground for Powdery Mildew and Botrytis. Conventional "burn-and-turn" chemical approaches often leave the plant stressed and more susceptible to the next round of infection.
By using a biology-first approach, we are building a more resilient plant. We aren't just preventing disease; we’re improving soil health and plant vitality. When you stop fighting nature and start installing the systems that nature already uses, the results speak for themselves.
It’s not magic, and it’s not a miracle product claim. It’s execution. If you start early, stay consistent, and treat your microbes like the essential infrastructure they are, you’ll stop being a firefighter and start being a grower again.

FAQ: Common Questions on Biological IPM
Q: Can I use this system with synthetic fertilizers?
A: You can, but be careful. High-salt synthetic fertilizers can suppress certain microbial populations. If you are using synthetics, we highly recommend regular applications of TerraBiotics Ultra Bio-Boost to buffer the soil biology, support nutrient mobility, and keep the root-zone biology active.
Q: Is MilStop safe to use late in flower?
A: MilStop is a potassium bicarbonate product and is generally considered safe and effective for late-stage applications, but always check your local regulations and testing requirements for hemp.
Q: How often should I apply the foliar tea?
A: For a preventative schedule, we recommend every 7–10 days. If you are in a high-pressure window (high humidity/temperature), you can tighten that to every 5 days. Consistency is key!
