About this Product

Don't let white mould in potatoes chip away at yield - protect your yield against white mould and get late blight protection at the same time!

  • Allegro fungicide protects your yield against white mould while providing foliar late blight protection at the same time.
  • Allegro provides excellent white mould control, and is particularly good at inhibiting the formation and movement of spores, effectively limiting the spread of disease.
  • Allegro also protects potato plants from the spread of late blight, stopping zoospores from moving to daughter tubers in the soil.
  • As a Group 29 fungicide, Allegro is an effective tool in your fungicide rotation and helps your resistance management program.

Unsurpassed white mould control in beans
Allegro fungicide inhibits the formation and movement of spores, thereby stopping disease before it takes over.  Allegro provides unsurpassed white mould control in dry and edible beans and has low use rates.

White mould control in soybeans Click here for use information on soybeans
White mould is caused by a soil-borne fungus, Sclerotinia sclerotiorum, which thrives in cool, wet conditions and creates white, cotton-like stem lesions that impact yield, plant stand and seed quality.  With the expanded label, Allegro fungicide can be applied to help growers proactively manage this disease.

Application Method

Air/Aerial, Ground

Application Information

Potatoes:

White mould

  • Make the first application at first bloom (10%) or just prior to row closure.
  • Make two back-to-back applications at intervals of 7–10 days.

Late blight

  • Begin application when plants are 15-20 cm tall or when conditions favour disease development.
  • Repeat application at intervals of 7-10 days.

Tuber late blight

  • Incorporate Allegro into your fungicide spray program at the end of the season up to desiccation to help to reduce tuber blight. Allegro will control spores still present on leaves and stems during drying time, as well as zoospores in the soil.


Dry and edible beans:

White mould

  • Begin application at the first sign of disease and no later than when plants are at first bloom to 10% bloom (when 10% of plants have at least one open bloom).
  • Make a second application 7-10 days later, but no later than when 50% of the plants have at least one open bloom.

Soybeans:

  • Begin applications at the R1 (early bloom) to R2 (full bloom) stage of development and, if needed, again 10- to 14-days later at early pod formation (R3).
  • DO NOT apply after growth stage R3, early pod formation
  • Apply Allegro 500F in sufficient water to obtain adequate coverage of foliage.
  • Applications should be made preventively.

Use Restrictions

Potatoes:

  • 14 day pre-harvest interval.
  • Do not apply more than the maximum seasonal use rate of 4 L/ha (1.6 L/ac) during each growing season.
  • Do not make more than three sequential applications of Allegro before alternating to a fungicide with a different mode of action.
  • Do not make more than 10 applications per year.


Dry and edible beans:

  • 14 day pre-harvest interval for dry shelled beans.
  • 30 day pre-harvest interval for edible podded legumes.
  • Do not apply more than 2 applications per year.
  • Areas treated may be replanted with potatoes and dry shelled beans as soon as practical after the last application.
  • Other root crops and leafy vegetables can be planted 30 days after the last application.
  • All other crops can be planted 70 days after application.

Soybeans:

  • Do not apply after growth stage R3, early pod formation.
  • Do not feed hay from treated fields to livestock.
  • Do not apply by air.

Store in a secure, dry place, separate from fertilizer, food or feed.

Tank Mixes

Potatoes:

Allegro can be tank-mixed with Reglone® at desiccation.

Consider tank-mixing Allegro with Ridomil Gold® 480SL fungicide to target late blight and provide suppression of primary pink rot* infection.
* There is known Ridomil Gold 480SL resistance to certain strains of late blight and pink rot. Ridomil Gold 480SL should always be tank-mixed with another product that controls late blight when targeting those diseases.
 

Dry beans:

Allegro can be tank mixed with Quadris® fungicide or Matador® insecticide.

Technical Information

Chemistry Group

Group 29 Fungicide

Mode of Action

Allegro has a multi-site mode of action. It is a protectant non-systemic fungicide that is very active against late blight, including spore stages. Allegro disrupts energy production in the fungus mitochondria.

Resistance Management

For resistance management purposes, please note that Allegro contains fluazinam, a Group 29 fungicide, which is considered to have a low risk of resistance development. However, as a general principle, it is recommended not to rely exclusively on the same product for pest control. To prolong effectiveness of this product, consult the label for resistance management strategies.

Allegro has a multi-site mode of action making development of resistant fungal strains extremely unlikely. This product is an excellent rotation partner for single-site mode of action products like Quadris.
