Goodbye Tordon

Sponsored post

The end is nigh – with the loss of Dichlobenil (Casoron G) in March 2010 and the final use-up time of June ’15 drawing closer for Tordon – the search for a suitable residual herbicide replacement becomes increasingly narrow. Tordon was a very effective liquid spray – capable of treating a wide variety of weeds – even the dreaded Japanese knotweed, while also providing a residual/pre-emergent benefit to prevent any weed re-growth.

There is still demand for the time, labour & cost-saving benefits of using pre-emergents and there are currently several options still available (see product examples below); ranging from soluble flazasulfuron to a liquid combination of glyphosate & diflufenican and a 750ml Nomix concentrated emulsion herbicide, which is still the only residual weed killer licensed for use on hard surfaces. During winter months too, propyzamide is a handy active that will deliver longer term grass & broad-leaved weed control.

Example products that contain: - 

  • Flazasufuron – Paradise, Chikara  (these products can be tank mixed with glyphosate to control existing weeds and deliver residual weed control.
  • Glyphosate - diflufenican – ProShield
  • Propyzamide – Kerb Flo, Kerb Granules  (Kerb Flo can be tank mixed with Flexidor (Active ingredient Isoxaben)
  • Isopropylamine sulfosulfuron – Nomix Dual (Can only be applied using a controlled droplet applicator) 

The pressure on herbicides has increased in recent years with ever more products being withdrawn.   Anyone who is interested can find out about current and future pesticide changes by using the excellent HSE – CRD website.  The Chemicals Regulation Directorate (CRD) is the agency that deals with all matters concerning pesticides. There are several databases, including the intended withdrawal and use up dates for current pesticide products: http://www.pesticides.gov.uk/guidance/industries/pesticides/topics/databases/databases-home

 If you are using any pesticides, no matter how frequently - guidance can also be found in the Code of Practice ‘Grey Book’.  It is essential reading and a good reference source on best practice and laws concerning the use, storage, transportation, etc of PPP’s (Plant Protection Products)

The Code of Practice for using Plant Protection Products can be downloaded so you can have it to hand any time or can be read online: http://www.pesticides.gov.uk/Resources/CRD/Migrated-Resources/Documents/C/Code_of_Practice_for_using_Plant_Protection_Products_-_Complete20Code.pdf

"We tried the grin but massively overpriced, the mulching performance no better than our 537HRX HY'S, not tried the Etesia but the HRX gives us the ability to collect when we need to without messing about with mulch plugs or swapping blades"
