Integrated Pest Management (IPM) in farming
Find out what IPM is and how to access funding and information to help apply it on your land.
Applies to England
IPM is a sustainable approach to managing pests, weeds and diseases on your land. It can be used by all farmers, growers, and land managers.
The aims of an IPM approach are to:
- support healthy crops using a range of plant protection methods
- support resilient and sustainable agricultural production
- help manage pesticide resistance
- encourage natural control mechanisms
- enhance wildlife and biodiversity
- reduce reliance on the use of chemical pesticides
IPM has applications for professionals and amateurs. Professional sectors include:
- agriculture
- horticulture
- forestry
- amenity
How to apply IPM
Prevention
You can use preventative methods to reduce the risk of pests, weeds and diseases becoming established. This can include:
- crop rotation
- encouraging natural predators
- cultivation and tillage practices (how the land is prepared to grow crops)
- growing pest-resistant varieties
- hygiene measures (for example, regular cleansing of machinery and equipment)
- using trap crops to draw away pests
Monitoring
Animals and plants classified as pests or weeds may be important to the structure and function of local ecosystems. Effective monitoring ensures you only use pesticides when necessary. You should choose the correct control method for your land and apply it at the right time. This can include:
- inspection of crops
- pest, weed and disease identification
- forecasting and assessing levels of pest populations
- the use of early diagnosis systems
- advice from professionally qualified individuals, advisers or agronomists
Use of thresholds
You can use thresholds which take into account pest, weed and disease pressures, region, crops and particular climatic conditions to help you decide when to use control measures.
Once a threshold, or predicted threshold, has been exceeded (such as when pest population levels, pest damage or weed prevalence become economically or environmentally unsustainable) you should take action to control the pest.
Intervention and control
The control methods you choose should be practical and effective. You can use sustainable physical, biological and other non-chemical methods.
Physical control measures can include:
- hand weeding and mechanical weeding
- physical barriers such as netting and mulching
Biological control measures can include:
- predatory species
- biopesticides, such as using microbes or pheromones to disrupt insect mating
If you use chemical pesticides, you should use:
- the minimum effective dose and application frequency
- targeted application to minimise potential negative impacts – for example, using precision technology like spot treatments and weed wipers
Managing pesticide resistance
You can use anti-resistance strategies to maintain the effectiveness of chemical pesticide products. This can include using:
- the appropriate dosage rates of pesticides
- pesticides with multiple modes of action
These strategies can be used when:
- the risk of resistance against a plant protection measure is known
- the level of harmful organisms requires repeated application of pesticides to the crops
Review and evaluation
Review the success of all plant protection and control measures regularly to ensure their effectiveness. This can be done by creating an IPM plan which you should review every year.
Creating your IPM plan
An IPM plan can help you:
- apply different control measures to your crops
- minimise the risks associated with the use of chemical pesticides
It should describe how you plan to apply IPM to your land. It can include details of:
- your land and the crops you grow
- the pests, weeds and diseases you have identified on your land
- control measures in the current season and plans for next season
You can find IPM plan templates online and you should decide which works best for you. This IPM plan template contains written guidance for certain crop types. This is optional and Defra does not require you to use this tool.
Assess your IPM approach using decisions support systems (DSS)
Decision support systems can help you manage and respond to different pest, weed and disease pressures to your crops.
Decision support systems include tools for:
- monitoring and treatment thresholds
- forecasting pest density and damage
- comparing treatments
You can find decision support systems online and you should decide which works best for you. IPM Decisions may help you assess which decision support systems are relevant to your land. This is optional and Defra does not require you to use this tool.
Funding for IPM
Sustainable Farming Incentive (SFI)
You can apply for funding under the Sustainable Farming Incentive (SFI) when you implement specific IPM actions, including:
- increasing knowledge and identifying opportunities for an IPM approach by completing an IPM plan
- creating habitats for natural crop pest predators
- using companion cropping to suppress weeds, reduce diseases and provide protection from crop pests
- minimising use of insecticides
- precision farming
Use the FIND tool to find actions that support IPM.
Capital items
You can apply for capital items to help you implement certain IPM approaches on your holding.
Use the Countryside Stewardship grant finder to find information about capital items.
Check our funding for farmers guidance for full details on available funding.
If you use pesticides professionally
If you use pesticides in a professional capacity, you must be registered with Defra. All users of professional plant protection products (PPPs) must hold an accredited certificate (unless you are working under the direct supervision of someone who holds one).
Distributors, advisors and professional users of pesticides have access to training by bodies approved by the regulator. Find the list of UK designated bodies and recognised specified certificates here.
