Soft fruit IPM Toolbox

1

Breeding resistant cultivars

  • The James Hutton Institute has been breeding aphid-resistant varieties using different genes for > 40 years.
  • Resistance to the main virus vector is now breaking down, therefore novel IPM tools must be developed.  Read more...

Alternative control methods

  • The Raspberry beetle is a major pest in raspberry cultivation, with females laying eggs in newly opened raspberry flowers.
  • We have designed, tested and produced a trap with Sentomol Ltd, which mimics the smell and colour of a giant raspberry flower.  Read more...

Biocontrol

  • Working with Koppest Ltd we have tested several parasitoid wasps in combination. These parasitise two aphid pest species, with 40% success in polytunnels and 80% success in glasshouses.  Read more...

Biopesticides

  • In HortLINK SCEPTRE project we have tested a range of cooled biopesticides with industry partners. These products are safer for the environment but need greater expertise to use in IPM compared to the currently used insecticides.

Pollinators and biocontrol

  • In RESAS funded research we have adapted a technique from New Zealand’s vineyards; using flowering buckwheat to attract and retains key predators (hoverflies) in polytunnels.
  •  Hoverflies have the added benefit of also acting as pollinators.

Raspberry IPM

  • Once several IPM tools are identified they are tested on-farm to optimise their efficacy when used in combination.
  • Overall, the Hutton Soft Fruit IPM toolbox has reduced pesticide reliance by > 40% for key pests: aphids, raspberry beetle.
  • New pests like spotted wing Drosophila threaten existing IPM systems, so the toolbox must continuously adapt to changing threats, climate and agronomy.
