Zorvec Endavia®


Realise unmatched consistency and disease control of late blight (Phytophthora infestans) in potatoes and downy mildew (Peronospora destructor) in onions.

Zorvec Endavia® disease control provides an unrivalled combination of consistency and control to help you grow a better crop, even under the most challenging environmental conditions.


Using Zorvec Endavia delivers two AIs from different fungicide groups, ensuring a robust anti-resistance strategy. Zorvec (oxathiapiprolin) has no known cross resistance from other fungicide groups, while co-formulating Zorvec (FRAC group 49) with benthiavalicarb (FRAC group 40) provides a solid anti-resistance strategy for both molecules. 


Zorvec Endavia® co-formulation is available in a convenient 5L bottle.

About Zorvec Endavia®



  • Zorvec Endavia provides unrivalled preventative and curative activity versus potato late blight (P. infestans), moving in the plant to protect new growth and adhering in the cuticle layer to control stem blight in addition to leaf borne late blight. 
  • Using Zorvec Endavia early in the blight programme at rapid growth will ensure best use of Zorvec’s unique properties in protecting stems as well as leaves. Zorvec moves upwards in the xylem, protecting new growth as well as that sprayed directly in the base of the crop.
  • Using 2 x Zorvec Endavia at rapid growth phase of the crop will provide a clean base to a blight programme, and leave up to a further 2 x Zorvec Endavia for use in the stable canopy phase, as determined by blight pressure.


Bulb Onions, Garlic and Shallots

  •  Zorvec Endavia provides unrivalled preventative activity versus downy mildew (P. destructor) in bulb onions, garlic and shallots.
  • Use early in the downy mildew programme to prevent disease establishing in the crop and preserve both yield and quality. 
  • Can be used on all varieties from the 3-leaf stage of growth.
  • Begin at first sight of disease in the crop with Zorvec Endavia at 0.5L/ha, to achieve 7 days protection against onion downy mildew. 
  • Apply a second application of Zorvec Endavia at 0.5L/ha at T1 + 7 days to establish a clean base within the crop, switching to an alternative chemical group for the next 1-2 applications. 
  • Retain the remaining application for use later in the fungicide programme, but be aware of the 28 day PHI.
