A water dispersible granule containing 50% w/w boscalid.

Filan is a protectant and systemic fungicide for use in oilseed rape for the control of Sclerotinia stem rot (Sclerotinia sclerotiorum) and dark leaf and pod spot (Alternaria brassicae).

 

OILSEED RAPE
Diseases:  Sclerotinia stem rot, Alternaria dark leaf, Pod spot, Phoma leaf spot,  Canker infection.
Rate: 0.5l/ha
Critical comments: Maximum total dose per crop: 1.0 kg/ha. Latest timing: Before 60% of pods have reached final size (GS 76).

 

Avoid spray drift on to neighbouring crops.

Filan represents minimal hazard to bees when used as directed. Consideration should be given to informing bee-keepers when you intend spraying crops in flower.

A reduction in Sclerotinia control may be observed in oilseed rape when high-risk infection conditions occur after flowering, leading to secondary spread of the disease through plant-to-plant contact, which may be more severe in lodged crops.

 

Filan is a protectant and systemic fungicide for use in oilseed rape for the control of Sclerotinia stem rot and Alternaria dark leaf and pod spot.

 

Filan contains boscalid which belongs to the SDHI (carboxamide) group of fungicides Currently there is no evidence of field strains of Sclerotinia sclerotiorum or Alternaria brassicae that are resistant to the carboxamide fungicides in oilseed rape.

Currently there is evidence of cross resistance between boscalid and other fungicides in the carboxamide group, but no cross resistance has been observed with fungicides with other modes of action.

The key of resistance management strategies is the reduction of selection pressure. This can be achieved by good agricultural practice which leads to less infection pressure (e.g. crop & stubble hygiene, use of less susceptible varieties, crop rotation, use of healthy seeds, etc).

Risk assessments for the target diseases on oilseed rape indicate a low or medium risk of resistance development. To minimise any possible risk of resistance occurring, the number of applications of Filan should be restricted to two per crop. Filan should be applied in a preventive manner, following the recommendations on the label, and as an integral part of a spray programme including fungicides with different modes of action.

Apply Filan as a protectant spray. Two applications can be made, up to and including when 50% of pods are at final size (GS 75 BBCH).

Applications against Sclerotinia should be made in high disease risk situations at early to full flower (GS 63-65 BBCH), before disease symptoms are visible.

Applications against Alternaria should be made from full flowering (GS 65 BBCH) up to and including when 50% of pods have reached final size (GS 75 BBCH). Applications made after the end of flowering (GS69) may result in reduced levels of control.

 

Never prepare more spray solution than is required.

Half fill the spray tank with clean water and start the agitation. Slowly add the required amount of Filan whilst re-circulating.

Rinse empty containers thoroughly, using an integrated pressure rinsing device or by manually rinsing three times. Add washings to tank at time of filling and dispose of container safely.

Add the remainder of the water and continue agitation until spraying is complete.

Apply 0.5kg of Filan in 220 - 400 litres of water per hectare as a MEDIUM spray, as defined by BCPC. In dense crops use the higher volume to achieve adequate penetration and good coverage of the crop.

Where possible use narrow-wheeled high clearance application equipment. To ensure optimum spray coverage and minimize spray drift, adjust the spray boom to the appropriate height above the crop, in according to guidance provided by the sprayer and/or nozzle manufacture.
