Q: How can I be sure what the problem is?
A: It is essential that the problem is accurately diagnosed. While identification of some pests and diseases is straight forward, for many others the symptoms can be similar. The underlying problem may even be a nutritional disorder rather than disease. Any doubts about the diagnosis should be referred to an expert.
Q: Is there anything new available to control Fusarium patch and red thread?
A: Surpass Pro, introduced by Headland Amenity, contains iprodione, which offers curative and preventive activity to control both Fusarium patch and red thread.
This versatile product can be tank mixed with Headland's Throttle fungicide and a range of its other plant protection products to give cost-effective, programmed disease control in the winter months.
Now available from Everris, ALS and Sherriff Amenity, Medallion TL is a broad-spectrum fungicide specifically approved for the control of Fusarium patch. It also has qualified use recommendation for useful control of leaf spot (Drechslera sp.) - based on limited data.
Used to clean up disease, Medallion TL will also give long-lasting protection from late autumn to early spring. Its Contact+ activity works to tackle disease with the fast knockdown of pathogens on the leaf, in the thatch and at the soil surface. This utilises the fungicidal activity of the active ingredient, fludioxonil, with maximum efficiency.
Bonding to the leaf wax layer, Medallion TL is rainfast in one hour. It is approved for use on all managed amenity turf and amenity grassland.
Particularly effective against Fusarium, anthracnose, dollar spot and brown patch, Mascot Exocet is new from Rigby Taylor. This systemic fungicide gives preventive, curative and eradicant activity. It is a member of the DMI-fungicides group (demethylation inhibitors), the active ingredient propiconazole working against fungal pathogens inside the plant and stopping disease development by inhibiting the biosynthesis of ergosterol.
The formulation ensures rapid uptake by the plant and systemic distribution around the plant via the xylem within an hour of application. The product can be used between April and October, with four sprays per season as a preventive programme when conditions favour disease development. Pack size is three litres - sufficient to cover 1ha.
Q: Have there been any developments to help spray operatives ensure that fungicides are applied evenly?
A: Vision Pro is the newest product to assist in applications. It has the advantage of being both a spraying aid to indicate sprayed areas and also a turf colourant - one that delivers some interesting science.
The product contains natural pigments, not dyes. Applied in autumn, winter and spring, it will increase radiation absorbance and decrease reflectance. The results are raised surface-soil temperatures and increased photosynthesis and metabolism at times of slow growth.
The ultraviolet-resistant formulation, developed by Becker Underwood and supplied by Sherriff Amenity, lasts for up to six-to-eight weeks. Application rate is 1.2 litres per hectare. Pack size is 2.5 litres - sufficient to cover 2ha.
Remember, it is mandatory to follow the instructions on pesticide labels and do not forget that the Control of Substances Hazardous to Health Regulations 1994 require employers to carry out a sufficient assessment of the risks to health and the environment before work starts.
