A suspension concentrate containing 133 g/l (12% w/w) boscalid and 60 g/l (5.4% w/w) metconazole.
Highgate is a protectant and systemic fungicide for use against late-season diseases in oilseed rape.
DIRECTIONS FOR USE
Highgate is a protectant and systemic fungicide for use in oilseed rape for the control of
Sclerotinia stem rot.
Restrictions/Warnings
Avoid spray drift on to neighbouring crops.
Highgate represents minimal hazard to bees when used as directed. Consideration should be given to informing bee-keepers when you intend spraying crops in flower.
Highgate should not be applied with pyrethroids to oilseed rape at flowering.
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.
After spraying, wash out sprayer thoroughly according to manufacturer’s guideline and dispose of washings and clean container according to DEFRA Code of Practice and local authority guidelines.
Disease Control
Highgate is a protectant and systemic fungicide for use in oilseed rape for the control of
Sclerotinia stem rot.
Resistance
Highgate contains boscalid, which belongs to the SDHI (carboxamide) group of fungicides, and metconazole, which belongs to the DMI group of fungicides.
Currently there is no evidence of field strains of Sclerotinia sclerotiorum, Alternaria brassicae or Phoma lingham that are resistant to SDHI or DMI fungicides in oilseed rape.
Currently there is evidence of cross resistance between boscalid and other fungicides in the SDHI group, but no cross resistance has been observed with fungicides with other modes of action.
The FRAC SBI Working Group recommends that all DMIs are considered as one product group in which general cross-resistance exists. Within the SBI-group, there is no cross-resistance between morpholines and DMI fungicides. There is no cross-resistance or a correlation in the sensitivity of triazoles to 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 Highgate should be restricted to two per crop. Highgate 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.
For further advice on resistance management in oilseed rape contact your agronomist or specialist advisor, and visit the Fungicide Resistance Action Committee (FRAC) and UK Fungicide Resistance Action Group (FRAG) websites.
Crops
Oilseed rape
Highgate can be used on all varieties of oilseed rape.
Time of Application
Apply Highgate as a protectant spray.
Applications against Sclerotinia should be made in high disease risk situations at early to full flower (GS 63-65 BBCH), to coincide with or just before first petal fall, and before disease symptoms are visible.
Two applications can be made up to and including when 50% of pods are at final size (BBCH GS 75), allowing a minimum interval of 14 days between applications. Applications made after the end of flowering (GS 69) may result in reduced levels of Sclerotinia control.
Mixing and Application
Mixing
Never prepare more spray solution than is required.
Three quarters fill the tank with clean water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of Highgate to the spray tank while re-circulating. Add the remainder of the water and continue agitation until spraying is complete.
When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).
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.
Application
Apply 1.0 l/ha Highgate in a recommended water volume of 200-300 litres of water per hectare as a MEDIUM spray, as defined by the BCPC. In dense crops, using the increased water volume will help 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, according to guidance provided by the sprayer and/or nozzle manufacture.
Following crops
Following crops after normally harvested oilseed rape
Any crop can follow normally harvested oilseed rape treated with Highgate.
Re-drilling due to crop failure
In the event of crop failure, any crop can be re-drilled after an interval of 5 weeks following of an application of Highgate.
