DIRECTIONS FOR USE
IMPORTANT: This leaflet is approved as part of the label. All instructions on this leaflet and on the label should be read carefully in order to obtain successful results from the use of this product.

WARNINGS
Use as a foliar or soil treatment may result in leaf scorch under very hot conditions.
Consult processor before using on crops grown for processing.

DISEASES CONTROLLED
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. The combination has multi-site activity and as such is ideal to include in disease control programmes as part of an anti-resistance management strategy. Direct effects against fungi prevent mycelial growth/penetration and spore production/ germination. These are supported by indirect effects which stimulate the plants natural defences (systemic acquired resistance). The following crop diseases are controlled:
Bremia lactucae (downy mildew) - Protected and outdoor lettuce
Peronospora parasitica (downy mildew) - Protected radish (Moderate control)
Pythium spp. (damping-off) - Lettuce, tomato, melon†, cucumber, Brussels sprouts, cabbage, cauliflower, Chinese cabbage, broccoli/calabrese, kale and collard

† Minor use qualification – Only limited evidence of crop safety is available
Additional benefits against other Oomycete fungi such as Phytophthora species can also be expected.
To ensure good control of Oomycete diseases, Previcur Energy must be applied in a protectant programme of treatments, before infections have occurred.

CROP SPECIFIC INFORMATION
Protected and outdoor lettuce:
For plants in propagation, Previcur Energy may be applied as a seedbed drench at a maximum individual dose of 3 ml product/m2 and a maximum total dose as a drench per crop of 6 ml product/m2. The first application should be 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). The latest time of application is pre-transplanting.
After transplanting, Previcur Energy may be applied as a foliar spray, at a maximum individual dose of 2.5 L product/ha in 200 to 1000 L water. The first application is recommended just after transplanting followed by a second dose approximately 10-14 days later. The total dose allowed as a spray application per crop is 5.0 L/ha. At least 21 days must be allowed between the final application and harvest.

Protected radish:
Previcur Energy may be applied as a foliar spray, at a maximum individual dose of 2.5 L product/ha in 200 to 1000 L water. The first application is recommended just after emergence of first true leaves followed by a second dose approximately 10-14 days later. The total dose allowed as a spray application per crop is 5.0 L/ha. At least 14 days must be allowed between the final application and harvest.

Brussels sprouts, cabbage, cauliflower, Chinese cabbage, broccoli/ calabrese, kale and collard (protected at time of application):
For plants in propagation, Previcur Energy may be applied as a seedbed drench at a maximum individual dose of 3 ml product/m2 and a maximum total dose as a drench per crop of 6 ml product/m2. 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). The latest time of application is pre-transplanting, after which plants can be transplanted outdoors in the field as required.

Protected tomato and cucumber:
Crops grown in soil or compost for propagation and cropping
For plants in propagation, Previcur Energy may be applied as a seedbed drench at a maximum individual dose of 3 ml product/m2 and a maximum total dose as a drench per crop of 6 ml product/m2 for tomatoes and cucumbers.
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). The latest time of application is pre-transplanting.
After transplanting, Previcur Energy may be applied via drip irrigation up to a maximum individual dose of 3.0 L/ha and a maximum total dose via drip irrigation per crop of 6.0 L/ha. 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). At least 3 days must be allowed between the final application and harvest.

Crops grown in artificial substrates for propagation and cropping
For plants in propagation, Previcur Energy may be applied as a seedbed drench at a maximum individual dose of 3 ml product/m2 and a maximum total dose as a drench per crop of 6 ml product/m2 for tomatoes and cucumbers. 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). The latest time of application is pre-transplantation.
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. It is also recommended that applications to newly transplanted cucumbers are made in the afternoon/evening when plant uptake will be slower.
After transplanting, Previcur Energy may be applied via drip irrigation up to a maximum individual dose of 3.0 l/ha and a maximum total dose via drip irrigation per crop of 12.0 l/ha. One dose is recommended just after transplanting followed by further doses at an interval of 7 to 10 days using a diluent volume of between 300-1500 l/ha). At least 3 days must be allowed between the final
application and harvest.

MIXING
Shake well before use
Ensure that the sprayer or other applicator is clean and set to give the correct volume of application and an even coverage. Half fill the sprayer or container with water then add the recommended quantity of Previcur Energy. Add the rest of the water and agitate the mixture thoroughly. The diluted product must be used IMMEDIATELY.

APPLICATION
Previcur Energy may be applied as a seedbed drench, via drip irrigation or as a foliar spray. For rates, water volumes, timings and restrictions of application see crop specific information. Additional advice is as follows:
Seedbed drench: For best results when drenching, thoroughly saturate the growing medium. The growing medium should be moist before application.
Foliar sprays: Boom height and water volume should be adjusted to ensure good coverage of the crop, particularly at later growth stages. In dense crops at later growth stages, higher water volumes should be used as recommended. Apply as a MEDIUM quality spray (for details see Boom Sprayers Handbook published by BCPC).
Trickle Irrigation: When applying by trickle irrigation systems, Previcur Energy should either be diluted in a bulk tank or through an injector type diluter. All application equipment should be washed/cleaned with water or dilute detergent solution and thoroughly rinsed three times.

Caution
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. When certain pathogens may develop resistance to Bayer CropScience products and since such circumstances are beyond our control, Bayer CropScience will be under no liability for any loss or damage whatsoever.
