18 GROW WITH THE IOG the Groundsman January 2014 Integrated pest management in the grounds and turf care industry IOG head of education and training, Chris Gray, gives guidance on the principles and benefits of Integrated Pest Management By: Chris Gray he term Integrated Pest Management (IPM) has evolved over many years, with the original emphasis being on insect pests and how to reduce their negative economic impact on crops. The term has since developed to include fungi, bacteria, weeds and other organisms within the term pests. [1] Organisms can develop resistance to pesticides and it is not sensible to apply heavier doses of a substance in an effort to control them. The consequences of heavier doses would be to further increase the ability of organisms to withstand the higher doses and to increase the potential for environmental pollution and harm to humans and wildlife. Evolved resistance is possibly the most serious problem from the routine usage of pesticides. [2] IPM is a practical approach that can help the turf grass manager in reducing and minimising pesticide use and also in reducing the problem of evolved resistance. T Regulatory requirements 'The Plant Protection Products (Sustainable Use) Regulations 2012' required the adoption of a National Action Plan which is to "ensure that the general principles of integrated pest management is implemented by all professional users by 1 January 2014." [3] The National Action Plan was published in February 2013 [4], with the co-ordinating body for the amenity landbased sector being the Amenity Forum which is also developing guidance on the use of integrated approaches. [5] The regulations were created as a means to support the harmonisation of standards across the EU for the safe and The chafer grub can be a serious pest in turf grass and amenity areas sustainable use of pesticides. [6] Human health, wildlife and the environment are of concern to everyone and without adequate safeguards the potential for environmental harm through inappropriate practices rises significantly: Pollution does not respect national boundaries. Definition of IPM There are many definitions for IPM. However, English Nature in 1996 provided a particularly useful one. Its definition emphasised the need to reduce the impact of pests on a crop as the "minimisation of crop losses to pests through a combination of cultural, biological and genetic methods in order to reduce requirement for chemical control, which is optimally applied on the basis of forecasting, monitoring and other techniques to maximise selectivity and minimise use." [7] Visit www.iog.org for more information and digital editions What are the principles of IPM? Eight principles of IPM have been identified as a minimum approach to the sustainable use of pesticides. These are: 1. Measures for prevention and / or suppression of harmful organisms; 2. Tools for monitoring; 3. Threshold values as basis for decisionmaking; 4. Non-chemical methods to be preferred; 5. Target-specificity and minimisation of side effects; 6. Reduction of use to necessary levels; 7. Application of anti-resistance strategies; 8. Records, monitoring, documentation and check of success. [8] Annex III of the 2009 EU Directive provides a more detailed description of these principles and how they might be addressed. [9]
