What is Previcur Energy?

A systemic multi-site fungicide for the;

  • control of downy mildew on protected and outdoor crops of lettuce
  • moderate control of downy mildew on protected crops of radish
  • control of ‘damping-off’ caused by Pythium spp for lettuce, broccoli/calabrese, cauliflower, Brussels sprouts, cabbage, Chinese cabbage, collard, kale, tomato, melon and cucumber seedlings during propagation under protection.
  • also, for protected crops of tomato, melon and cucumber against Pythium when applied through drip irrigation.

Additional benefits against other Oomycete fungi such as Phytophthora species can also be expected.

Restrictions

(1) Where two drenches are allowed on one crop then the first drench 
is restricted to pre-emergence use only.

(2) For use on cucumber (protected), tomato (protected) and melon (protected) in a soil or compost substrate the maximum total dose via drip irrigation must not exceed 6 L/ha/crop.

(3) For application by drip irrigation to tomato, melon and cucumber grown for cropping in artificial substrates. Previcur Energy must not be applied in a re-circulating system.

How Previcur Energy works

Previcur Energy contains propamocarb (530.0 g/L) and fosetyl (310.0 g/L), a combination of two active ingredients with proven efficacy at protecting the roots and aerial parts of broadleaved crops against Oomycete fungi.

Direct effects against fungi prevent mycelial growth/penetration and spore production/germination through direct inhibition of mitochondrial respiration. These are supported by indirect effects which stimulate the plants natural defences (systemic acquired resistance).

To ensure good control of Oomycete diseases, Previcur Energy must be applied in a protectant programme of treatments, before infections have occurred.

When and how to apply

Protected and outdoor lettuce

For the control of downy mildew (Bremia lactucae).

Application method
Drench
Foliar spray
Max individual dose
3 ml/m² 2.5 L/ha
Max total dose per crop
6 ml/m²/crop 5.0 L/ha
Latest time of application
Pre-transplantation 21 days before harvest

Before transplanting

For plants in propagation, Previcur Energy may be applied as a seedbed drench. The first drench application should be pre-emergence, just after sowing, followed by a second application after crop emergence, approximately 10–14 days later. Where two drench applications are made the first must be pre-emergence. Thoroughly drench the compost using a diluent volume of between 2 and 4 L/m2 (20,000-40,000 L/ha).

After transplanting

After transplanting, Previcur Energy may be applied as a foliar spray at a maximum individual dose of 2.5 L/ha in 200 to 1000 L of water. The first application is recommended just after transplanting followed by a second dose approximately 10–14 days later.

Before transplanting

For plants in propagation, Previcur Energy may be applied as a seedbed drench. The first application is recommended pre-emergence, just after sowing, followed by a second application after crop emergence, approximately 10-14 days later. Thoroughly drench the compost using a diluent volume of between 2 and 4 L/m2 (20,000–40,000 L/ha).

After transplanting

After transplanting, Previcur Energy may be applied via drip irrigation. One dose is recommended just after transplanting followed by a second dose approximately 10-14 days later using a diluent volume of between 300–1500 L/ha).

To reduce the risk of phytotoxicity (plant selectivity) in cucumbers grown on artificial substrates, use up to 1 litre of product per hectare in the first 10
days after transplanting followed by further doses at an interval of 7 to 10 days. It is also recommended that applications to newly transplanted cucumbers are made in the afternoon/evening when plant uptake will be slower.

EAMU – Outdoor spinach

This Extension of Authorisation relates to the use of Previcur Energy as a fungicide on outdoor crops of spinach for the control of Peronospora farinosa (downy mildew).
Application to be made between May and September via conventional hydraulic sprayer, or hand held equipment, in a water volume of 250 to 1000 litres/ha.
A minimum interval of 7 to 10 days between applications is applicable.
To ensure good control of Oomycete diseases, Previcur Energy must be applied in a protectant programme of treatments, before infections have occurred.
Trials have shown some phytotoxicity under certain conditions. Growers are therefore advised to use with care.

Resistance management

Previcur Energy contains two active substances providing multi-site activity and as such is ideal for inclusion in disease control programmes as part of an anti-resistance management strategy. The possible development of pathogens resistant to Previcur Energy cannot be excluded or predicted. Where such resistant strains occur, Previcur Energy is unlikely to give satisfactory control.
