Spider mite alert

With spider mite pressures increasing ahead of second crops being planted, Jasper Hubert a consultant at Koppert Biological Systems, urges growers to ensure that their crops are protected from the pest throughout the season.

With spider mite pressures increasing ahead of second crops being planted, Jasper Hubert a consultant at Koppert Biological Systems, urges growers to ensure that their crops are protected from the pest throughout the season.

“Growers are noticing increased levels of spider mite due to the build-up of resistance to conventional products.

“Therefore, it’s very important to alternate conventional chemistry and incorporate biologicals in a robust Integrated Pest Management (IPM) approach, to hit the pest from multiple angles, and ensure that resistance is reduced.

“Biologicals have a huge part to play in reducing pesticide resistance as essentially, there is no possibility of developing resistance against biological control agents."

Eradicoat

“Eradicoat is useful for so many reasons, which is why I recommend that growers have it in stock at all times,” explains Mr Hubert.

“The zero-harvest interval enables growers to use the product at short notice, meaning that they can be extremely reactive to pest pressures, even close to harvest time.

“Eradicoat’s IPM compatibility is another big plus point for me. It dramatically reduces the spider mite population, while being safe for Phytoseiulus, creating a more favourable balance between the pest and predatory mites.

“Along with this, its low residual activity makes it extremely useful in an IPM approach, as it allows other beneficial insects to be used within a couple of hours of the Eradicoat application.

“Overall, products such as Eradicoat are playing a huge part in helping growers to address resistance issues and effectively control pests,” he says.

Jasper’s top tips for spider mite control:

  • Plan ahead – establish a timeline of forecast pest pressures and ensure you’re prepared with control products, at the beginning of the season and review throughout
  • Finish clean, start clean – utilise clean up sprays between crops to reduce pest pressures before the next cropping cycle
  • Regular scouting – crop walk regularly and handle the plants to see if spider mites are present
  • React to pest pressures quickly – if pests are identified in the crop before damage has been done, control will be quicker and much more cost effective
  • Compatibility of pesticides – understand how beneficial insects and conventional chemistry work together, to ensure you are getting the best possible efficacy
