Application Information

Use Rates

  • 20 mL/100 kg seed
  • One jug of Cruiser Maxx Potato Extreme will treat 1058 cwt

Water Volume

  • Apply Cruiser Maxx Potato Extreme as a water-based slurry utilizing standard slurry seed treatment equipment that provides uniform seed coverage. 
  • Thoroughly mix the specified amount of Cruiser Maxx Potato Extreme into the required amount of water or tank mix partner for the slurry treater and dilution rate to be used.

Application Method

Seed Treatment

Application Information

  • Shake or mix well before using.
  • Apply using standard seed treatment equipment that provides uniform seed coverage.  Uneven or incomplete seed coverage may not give the desired level of disease control.
  • Follow the manufacturer’s application instructions for the seed treatment equipment being used.
  • Apply only in areas with adequate ventilation or in areas that are equipped to remove mist or dust.
  • Follow best management practices when cutting and treating your seed. For more information on best management practices, contact your Syngenta representative.

Effects of Weather

  • If soil conditions are ideal, plant potatoes immediately after application
  • However, if planting conditions will not be favourable following application, either a) wait to cut, treat, plant until conditions improve or b) cut, treat and store.
  • See best management practices for more information

Use Restrictions

  • Do not plant more than 128 700 kg of treated potato seed pieces/day. Refer to label for more information on planting rates and areas.
  • Cut and treated seed should not be piled above 1.8 m in height. 
  • Avoid storing treated potatoes for over 2 weeks. 
  • Do not store treated seed in trucks or in boxes.
  • When transporting cut and treated seed make sure the seed is covered.
  • Avoid using a liquid seed treatment on excessively sprouted seed. The issue is not phytotoxicity; broken sprouts create entry points for infection.
  • Do not apply any subsequent application of thiamethoxam in-furrow or foliar application or other group 4 insecticide following seed piece treatment with Cruiser Maxx Potato Extreme.

Technical Information

Chemistry Group

Group 12 and Group 3 Fungicides; Group 4 Insecticide

Mode of Action

Cruiser Maxx Potato Extreme contains the fungicides Fludioxonil (Group 12) and Difenoconazole (Group 3), and the insecticide Thiamethoxam (Group 4).

Fludioxonil = Group 12 = phenylpyrroles – affects signal transduction

Difenoconazole = Group 3 = triazole – inhibits sterol biosynthesis

Thiamethoxam = Group 4A = neonicotinoid – affects nerve action

Resistance Management

Resistance-Management Recommendations

For resistance management, please note that Cruiser Maxx Potato Extreme contains a Group 4 insecticide (neonicotinoid class of chemistry) and Group 3 and 12 fungicides. Any insect or fungal population may contain individuals naturally resistant to Cruiser Maxx Potato Extreme and other Group 4 insecticides or Group 3 and 12 fungicides. A gradual or total loss of pest control may occur over time if these insecticides and fungicides are used repeatedly in the same fields. Other resistance mechanisms that are not linked to site of action but are specific for individual chemicals, such as enhanced metabolism, may also exist. Because resistance development cannot be predicted, the use of this product should conform to sound resistance management strategies established for the crop and use area.

To delay insecticide and fungicide resistance:

Where possible, rotate the use of Cruiser Maxx Potato Extreme with different groups that control the same pests in a field. Use tank mixtures with insecticides and fungicides from different groups when such use is permitted.

Pesticide use should be based on an IPM program that includes scouting, historical information related to pesticide use and crop rotation and considers cultural, biological and other chemical control practices. Implement an integrated disease management program that helps to maintain lower inoculum levels, thereby reducing the probability for the development of resistant Fusarium spp. isolates. This includes planting disease free tubers, not growing potatoes in the same field two years in a row and practising good hygiene in the storage bins.

In order to minimize the potential for the development of resistance among the labeled disease organisms do not use Cruiser Maxx Potato Extreme in any two consecutive seed generations.

If disease continues to progress after treatment with this product, do not increase the use rate. Discontinue use of this product, and switch to another fungicide with a different target site of action, if available.

Monitor treated pest populations for resistance development.

Contact your local extension specialist or certified crop advisors for any additional pesticide resistance-management and/or IPM recommendations for the specific site and pest problems in your area.
