The decision support system for AstroKerb® and Kerb® Flo 500 is starting the first week of October and will be available 24/7 on the Dow AgroSciences main web site ((http://uk.dowagro.com/oilseed-rape-to-spray-or-not-to-spray/) and also on the Farming On-Line web site. It takes the form of a traffic light system, indicating when soil temperatures are coming right for application of these residual herbicides in every individual postcode area across the UK.
Temperature and soil moisture are critical to getting the best performance from Dow AgroSciences’ two leading oilseed rape herbicides – Kerb® Flo 500 and ASTROkerb®. The Dow AgroSciences’ postcode checker as seen here is an online tool that will help decide when it is time to spray. It could not be simpler, type in your postcode and the result appears as a traffic light : Red means wait; Amber means get ready and Green means consider going. It is rare that you will get a green light before November, but as both products can be used up to January 31st, there is no rush.
