A relatively quiet month through May as some people begin to take holidays but the BCPC Congress in Harrogate promises to address the likely impact of the Brexit re-set and I for one am very interested to hear what the speakers have to say.

New Approvals by Company:

Albaugh

  • has extended the range of crops on the Flame Duo label (florasulam + tribenuron-methyl) to include oats, rye, spelt, triticale and spring wheat.

Barclay

  • has duplicated its glyphosate product Ardee XL with a new MAPP No (M21719) for use in NI only while the original (M17515) continues in GB but expires in NI 30/11/2027.

BASF

  • has extended the range of crops on the Vayo label (M20549, mefentrifluconazole) to include strawberries, protected strawberries and protected aubergines, courgettes, cucumbers, gherkins and summer squash under permanent protection with full enclosure.

Bayer

  • has confirmed that it will be marketing a new mix of actives in 2027 – aclonifen + diflufenican + flufenacet for use in GB only where Challenge Plus (M21008) or Mateno Star (M21174) will offer pre-em weed control in winter wheat and winter barley. Bayer also has a new approval for the active in Serenade ASO – Bacillus amyloliquefaciens (Strain 713).  Called Rhapsody, it is approved for use in oilseed rape, wheat, barley, rye and triticale in GB only but it is currently listed as PAR in UKPG since the diseases that it is active against are not yet known to me.

Certis Belchim

  • has duplicated its new blight fungicide Areli under a new name – Valdina (M21705, cyazofamid + valifenalate) for use in GB only. Areli is confirmed as available to 2027 while Valdina is still only listed as PAR in UKPG.

Clayton

  • has another straight fluazinam product in Clayton Surinam (M21654) which is approved in both GB and NI until 31/5/2030 – longer than other fluazinam products which currently expire October 2028.

Fargro

  • Leptinox Plus has a new MAPP No (M21436, Bacillus thuringiensis kurstaki E2348) for use in GB only and has three new crops on the label – amenity vegetation, natural vegetation and ornamental plant production. Use in NI expires 15/2/2027.

FMC Agro

  • has duplicated its Concert SX and Pennant (metsulfuron-methyl + thifensulfuron-methyl) with new MAPP Nos (M21661 & 21662) which now expire 28/2/2029 while the approval of the originals has been reduced from 9/9/2099 to 31/10/2027. Also duplicated is Calibre Max SX (M20826 & 21763, thifensulfuron-me + tribenuron-me) with the former now expiring 30/11/2027 while the new approval lasts until 30/4/2034. FMC Agro also now has a Wolverine mimic in Mezzanu (M21709, fluxapyroxad + metconazole) for use in GB only which has been added to the database as PAR.

Globachem

  • has gained approval for a new fungicide for use in wheat and trirticale. Called Firuza (M21704) it contains a mixture of prothioconazole and the inorganic potassium phosphonate.  The range of diseases controlled has not yet been known to me so it is currently listed as PAR until a label becomes available.

Hockley

  • has duplicated its two 360 g/l glyphosate products Hi-Phosate with the slightly catchier name of Cleanground 360.  Like the Hi-Phosate products, one (M21692) is specific for GB and the other (M21699) is specific for NI only.

Nufarm

  • has duplicated its Bolt, Fragma Max and Supreme Max products with new MAPP Nos (M21488, 21701 & 21703, florasulam + tribenuron-methyl) which are approved until 30/6/2033 while the approval of the originals has been reduced from 9/9/2099 to 31/10/2027 or 30/11/2027 according to product.

Ninja

  • Ninja Agriculture Ltd is a new addition to list of UKPG suppliers which has an office in Covent Garden, London, and currently has only one product approved by CRD. This product is Suriken (M21657, spinosad) and is a mimic of most of the other spinosad products approved by CRD.  It is currently entered as PAR and is approved for use in GB only.

Rainbow

  • has gained approval of a mimic of Amistar Max which is called Aster Plus (M21660) for use in GB only and it is listed as PAR until availability in the market is confirmed.

Rovenska

  • This new supplier has an approval now for Tec-Bom which contains potassium salts of fatty acids.

Syngenta

  • has a new product for disease control in managed amenity turf called Vertenza. It is an EC formulation of straight prothioconazole that contains 320 g/l.  It is currently listed as PAR in UKPG while I wait for a label to become available.

EAMUs added:

  • Arizona (M21116, folpet) now has three EAMUs allowing treatment of ornamentals and hardy nursery stock, including protected specimens, against a wide range of diseases such as black spot, anthracnose, box blight, scab, powdery and downy mildew and white mould.

  • SL 657a (M20652, metalaxyl-M) has 3 new EAMUs allowing treatment of downy mildew in hops, table & wine grapes and in red beet where it can also be used against root malformation disorder.
  • Zorvec Enicade (M20366, oxathiapiprolin) has its first EAMU allowing treatment of downy mildew in wine grapes with just a 14 day harvest interval.
