Strawberries, Ornamentals – Two-spotted mite (π˜›π˜¦π˜΅π˜³π˜’π˜―π˜Ίπ˜€π˜©π˜Άπ˜΄ 𝘢𝘳𝘡π˜ͺ𝘀𝘒𝘦)

Crop:Β  Β  Β  Β  Β Strawberries, Ornamentals
Insect(s): Two-spotted Mite (Tetranychus urticae)

Guidelines:

  1. Monitor mite activity and treat infestations before thresholds are reached, i.e. spray earlier rather than later. Seek advice on local threshold levels.
  2. Do not apply sequential applications of products from any one chemical group. This does not apply to various oils or sulfur as they are considered to have a lower resistance risk.
  3. Preferably products with the same Mode of Action should not be used more than twice in a growing season. This does not apply to various oils or sulfur as they are considered to have a lower resistance risk.
  4. Incorporate the use of predatory mites for the control of this pest wherever possible.

Notes regarding the application of insecticides:

  1. To ensure the most effective control of the pest:
  2. Product labels should at all times be carefully read and adhered to;
  3. Full recommended rates of registered insecticides should always be used; and
  4. Ensure good coverage of the target area to maximise contact.

CropLife Australia’s Resistance Management Strategies provide a guide for crop protection product rotation through product groups. The strategies are a useful tool that supports farmers’ adoption of resistance management. All crop protection products must be handled and applied strictly as specified on the product label or APVMA permits.

These Resistance Management Strategies do not replace product labels. They are a guide only and do not endorse particular products, groups of products or cultural methods in terms of their performance. It is important to check with the Australian regulator’s (APVMA) product database for contemporary information on products and active constituents. The database can be sourced through www.apvma.gov.au

The information given in this strategy is provided in good faith and without any liability for loss or damage suffered as a result of its application and use. Advice given in this strategy is valid as at 26 June 2024. All previous versions of this strategy are now invalid.
