Fargro supplies biological pest control solutions to commercial growers across the UK - helping to reduce reliance on conventional chemistry through targeted, evidence-based Integrated Pest Management (IPM). With over 80 years of horticultural expertise and a Royal Warrant held for more than 50 years, we bring the knowledge and the products to make biological control work in practice, not just in principle.
Whether you're managing ornamentals, soft fruit, herbs, or protected crops, our biological control programmes support healthier plants, improved resilience, and long-term crop consistency - as part of a wider Holistic Growing approach.
A whole-system approach to pest control
IPM combines biological controls, cultural practices, crop hygiene, monitoring, and data-led decision-making to deliver reliable, long-term protection. At Fargro, IPM informs our product recommendations, our site visits, and our technical diagnostics - it's woven into everything we do. We don't just supply biological controls and step back. We design programmes, walk crops, check compatibility, and stay involved through the season.
Our IPM support includes:
- Tailored biological control programmes for your crop, pest pressure, and growing environment
- Crop-specific pest prevention planning - before problems take hold
- Crop walks and on-site monitoring
- Compatibility advice for existing inputs and programmes
- Seasonal planning to time biological introductions correctly
- Monitoring tools and best-practice application guidance

HOW BIOLOGICAL CONTROLS HELP
Biological controls for more resilient crops
We supply a full range of biological controls used by professional growers across the UK - each chosen for efficacy, reliability, and compatibility with IPM systems, supplied through our partnership with Koppert Biological Controls.
Reduce reliance on conventional pesticides
Natural predators and parasitoids target specific pests - lowering resistance risk and supporting more sustainable production.
Support residue-free production
Biological controls leave no chemical residues - increasingly important for growers supplying retailers with strict residue requirements.
Improve pest resistance management
Rotating biological controls within an IPM programme helps manage resistance build-up that makes conventional chemistry less effective over time
Promote a healthier crop environment
A well-managed biological programme supports beneficial microbial activity and reduces physiological stress caused by repeated chemical applications.
APPLICATION
Correct application makes the difference
Biological controls are highly effective when applied correctly - and significantly less so when they're not. Temperature, humidity, timing, crop stage, and input compatibility all affect programme performance. This is where Fargro's technical support makes a real difference.
Our application support includes:
- Compatibility checks with chemical inputs - before you commit, not after something goes wrong
- Climate condition advice for specific predators and organisms
- Nutritional support to strengthen crop tolerance to pest pressure
- Data-led monitoring to inform better IPM decisions
- Problem-solving for challenging pests or growing environments

COMMON QUESTIONS
What is biological pest control and how does it work?
Biological pest control uses living organisms - beneficial insects, nematodes, and natural predators - to manage pest populations without chemical residues or resistance risk.
Are biological controls suitable for all commercial crops?
They've been used successfully across ornamentals, hardy nursery stock, soft fruit, herbs, and outdoor crops. Programme design varies by crop and environment - our team will advise on the right approach.
Can biological controls be used alongside conventional pesticides?
Yes - but compatibility needs careful management. Some conventional inputs are harmful to beneficial organisms. Fargro provides specific compatibility advice before you commit to a programme.
When is the right time to introduce biological controls?
Earlier is almost always better - introducing biologicals before pest populations build gives the best results. We advise on optimal timing for your crop calendar and specific organisms.
How do I get started with a biological control programme?
Contact our Bios team for an initial conversation about your crop, growing environment, and current pest management approach. We'll design a programme tailored to your situation.
