The CONVISO SMART system comprising a highly effective herbicide and varieties tolerant to the active substances will be available to growers for use in spring 2020 following the addition of the first ALS-tolerant variety to the BBRO Recommended List and the approval of the CONVISO ONE herbicide.
The system will make weed control simpler and easier for growers given its broad spectrum of activity and crop-safe ease of application.
Containing foramsulfuron and thiencarbazone-methyl, two highly active ALS herbicides, CONVISO ONE is a dedicated herbicide for use with ALS-tolerant varieties.
“The CONVISO SMART system will simplify weed control by reducing the number of sprays and mixes required to keep the sugar beet crop clean [of weeds]. This will improve ease of management and free-up the sprayer at what is a busy time of the year for growers,” explains Edward Hagues, Bayer campaign manager for root crops.
“Foramsulfuron is mainly a leaf contact herbicide whereas thiencarbazone-methyl works on both the leaf and in the soil with residual effect.
“The CONVISO ONE herbicide features an outstanding level of control against a broad spectrum of weeds from a single application. This includes some difficult to control species, including Polygonums and others such as annual mercury (Mercurialis annua), fool’s parsley (Aethusa cynapium) and cleavers (Galium aparine),” adds Mr Hagues.
The product is formulated as an oil dispersion (OD) mix and is registered with a maximum application rate of 1L/ha per season. The herbicide will be applied as a single dose timed at two to four true leaves stage of weed growth.
Bred specifically to be used in the CONVISO SMART weed control system for sugar beet, SMART JANNINKA KWS is the first variety to be added to the BBRO Recommended List following more than 20 years of research and development to provide the next step in weed control.
In addition, three further varieties have been added to the UK’s National List, SMART BREANNA KWS, SMART RIVETTA KWS and SMART SANYA KWS.
These varieties, while not yet added to the Recommended List, will offer growers a choice of varieties for drilling, potentially as early as spring 2020.
Offering their best performance when drilled from mid-March onwards the CONVISO SMART varieties represent the first choice for more convenient, more effective weed control in sugar beet.
SMART JANNINKA KWS has an adjusted yield of 90% of controls when grown under a herbicide regime based around classical products, however its performance increases by more than 5% when grown under the CONVISO SMART system.
“Effectively yielding at over 95% of controls, SMART JANNINKA KWS is close to the performance achieved by some of the established varieties on the 2020 Recommended List,” says Ben Bishop, KWS sugar beet UK country manager.
“CONVISO SMART represents a compelling proposition and we have sufficient seed to meet anticipated demand. Growers can expect the price to reflect the benefits of the technology, but for the majority, we expect it to represent good value,” he adds.
KWS and Bayer intend to publish stewardship guidelines for the CONVISO SMART system ahead of the 2020 season.
