Science Into Practice - Improving approaches to crop protection

Integrated crop management (ICM) integrates the use of both non-chemical and reduced or alternative chemical pesticide practices for the effective management of pests, diseases and weeds.

It includes: the use of good growing conditions and husbandry; monitoring of pest problems and awareness of thresholds; preference for non-chemical control measures; use of biological control agents; use of specific and targeted pesticides; use of optimum application methods; avoiding chemical programmes that could promote resistance; and checking control success then modifying programmes.

The UK nursery stock industry has adopted ICM to varying degrees. But until now there has been no attempt to bring together these many strands of ICM knowledge and combine them with best practice among hardy nursery stock growers.

Project HNS 185 aims to assess the use of ICM by the sector and identify potential for wider uptake to enable producers to develop practices to replace pesticides, particularly those that at a higher risk of being lost to the industry. Fieldand container-grown stock will be included.

Growers will be presented with cost-effective ICM practices as the review will bring together information on what is available for ICM in the UK and the current level of uptake and satisfaction among growers.


Please see the news section of the HDC website for the survey, which aims to gather information on how the nursery stock industry currently approaches crop protection to identify ways to improve.
