About this Product

Allegro: the white mould authority

Understanding White mould:
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. It is the most devastating soybean disease in Canada, with potential yield losses of up to 75%*. In order to combat this disease, genetics, fungicides and management practices can all be considered as useful tools.

Product Benefits

  • The reduced rate of 0.176 L/ac (0.44 L/ha) can be applied for the suppression of white mold in soybeans.
  • Field scale trials show a high return on investment when white mould infection is present

Packaging

One case contains 2 x 10L jugs

Uses

For use on:

Soybeans

For management of:

White mould (suppression and control).  How white mould impacts your farm:

  • Infected plants may not produce seed
  • For every 10% increase in incidence of white mould at R7 growth stage, yield is reduced by 2–5 bu/ac**
  • White mould can survive in the soil for several years, what’s more, one bad infection year can impact future susceptible crops

Application Information

Graphic depiction of soybean growth stages
When it comes to managing white mould, application timing is critical. By the time you start to see white mould in the field, it’s too late! Traditional fungicide application timings (R3) can be too late to protect your soybeans from white mould. If current or future conditions are conducive to white mould, be prepared to make an application at R1 (the beginning of flowering), which will allow for better coverage in the canopy. If cool, wet weather continues, a second application may be necessary.
  • 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).
  • Apply Allegro 500F in sufficient water to obtain adequate coverage of foliage.
  • Applications should be made preventively.

Use Restrictions

  • DO NOT apply after growth stage R3, early pod formation.
  • Do not allow livestock to graze treated areas.
  • DO NOT feed hay from treated fields to livestock.
