Zorvec Endavia®

Fungicide

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 a combination of consistency and control to help you grow a better crop, even under the most challenging environmental conditions.

 

Zorvec trials in 2023 show it remains proven as an effective active ingredient against late blight. It delivered persistent, systemic and curative activity under severe late blight pressure during August and September. The Zorvec ‘Bonus’ benefit is seen in Stable Canopy phase from application in Rapid Growth phase 1-3 weeks depending on disease pressure.

 

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

About Zorvec Endavia®

2024 Application Advice

To reduce the potential risk of resistance within the UK and Ireland, Corteva have issued the following application advice for the potato ware crop;

  • Apply Zorvec products strictly in alternation with effective chemistry having a different mode of action, other than CAA (benthiavalicarb, mandipropamid, dimethomorph)
  • The post-Zorvec application interval to the following non-Zorvec containing spray should not exceed 7 days.
  • In curative situations (disease evident or confirmed in local area) Zorvec co-formulations should be applied in tank-mix with a partner fungicide containing a curative active ingredient e.g. cymoxanil or propamocarb.​
  • Sprays containing Zorvec should not exceed 20% of the total number of sprays applied to the crop – two sprays per crop if the expected programme is less than 15 sprays.
  • A single crop should not receive more than 3 sprays containing Zorvec products.


For seed crops (incl home-saved seed) the following must also be observed;

  • Zorvec applications must always be applied with a full rate of a curative fungicide e.g. cymoxanil.
  • A single crop should not receive more than 2 sprays containing Zorvec products and these 2 sprays should not exceed 20% of the total late blight programme.

Benefits

Potatoes

  • 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.

 

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.
