What should I do with bolters of SMART KWS varieties?

If bolters appear – pull them, like in classic sugarbeet. Pulling early before they start maturing is most efficient. Strictly avoid building up ALS-tolerant weed beet. Weed beet of SMART varieties cannot be controlled with CONVISO ONE or classic herbicides.

CONVISO® SMART

CONVISO® SMART – a valuable system

Q: What is the control spectrum of CONVISO ONE?

CONVISO SMART has good results against hard to fight weeds such as Abutilon, Aethusa, Ambrosia, Mercurialis, Polygonum and Sorghum.

Q: What is the correct application timing for CONVISO ONE?

Depending on the country regulations, CONVISO ONE can be used in a split (2 × 0.5 l/ha) or single (1 × 1.0 l/ha) application.

Q: How do I apply CONVISO ONE?

Depending on the country regulations, CONVISO ONE can be used in a split (2 × 0.5 l/ha) or single (1 × 1.0 l/ha) application. Split application 2 × 0.5 l/ha: 1st application when the first plants of fat hen (Chenopodium album) reach the 2 true leaf stage (BBCH 12); 2nd application when new emerging plants reach the 2 true leaf stage, with a minimum interval of 10 days after the first. If fat hen is not present in the field, apply when the first plants of other weed species reach a maximum of 2 true leaves (BBCH 12).

Q: How can I distinguish between SMART KWS and classic seed?

SMART KWS seed has a purple inner pelleting mass whereas classic KWS sugarbeet seed is grey on the inside. Both pellets are orange on the outside. Never mix classic seed with SMART KWS seed.

SMART Choice

Unique Control

CONVISO^® SMART offers a unique weed control of broadleaf as well as sensitive grass weeds.

Higher Productivity

CONVISO^® SMART offers best crop safety and therefore applications more independent from the growth stage and physical condition the beet.

Fewer applications

CONVISO^® SMART offers greater flexibility in weed control combined with less applications needed.

SMART Teamwork

SMART KWS seeds and the CONVISO^® ONE herbicide by Bayer are working hand in hand.

CONVISO® SMART - the SMART innovation in sugar beet weed control

What is the control spectrum of CONVISO® ONE?

CONVISO^® SMART has good results against hard to fight weeds such as:

Abutilon
Aethusa
Ambrosia
Mercurialis
Polygonum
Sorghum

What is the correct application timing for CONVISO® ONE?

Depending on the countries reglementation, CONIVSO^® ONE can be used in a split (2×0.5 l/ha) or single (1×1.0 l/ha) application.

*if not present, apply when other weeds reach the same true leaf stage

Correct timing is key for the success of the CONVISO^® SMART system.
Always follow the growth stage of the indicator weed fat hen (Chenopodium album).

How do I apply CONVISO® ONE?

Depending on the countries reglementation, CONIVSO^® ONE can be used in a split (2×0.5 l/ha) or single (1×1.0 l/ha) application.

Split application 2×0.5 l/ha

* Country specific recommendations apply

1^st application: When the first plants (not the average weed population!) of fat hen (Chenopodium album) in the field reach the 2 true leaf stage (BBCH 12).
2^nd application: When new emerging plants of fat hen reach the 2 true leaf stage, but with a minimum interval of 10 days after first application.
No fat hen in the field: apply when the first plants of other weed species reach max. 2 true leaf stage (BBCH 12).

Single application 1×1.0 l/ha

* Country specific recommendations apply

Correct application timing: When the first plants of fat hen (Chenopodium album) reach 4 true leaves (BBCH 14).
No fat hen in the field: apply when the first plants of other weed species reach max. 4 true leaf stage (BBCH 14).

Integrated Weed Management with CONVISO® SMART

The base for a SMART weed control

Integrated Weed Management (IWM) lays the foundation for your professional CONVISO^® SMART sugarbeet cultivation.

Your key to success is the combination of chemical, mechanical, cultural and biological IWM measures which fit best to your situation.

Target: leave 0 bolters on the field!

If bolters appear – pull them, like in classic sugarbeet.
Pulling early before they start maturing is most efficient.
Strictly avoid building up ALS-tolerant weed beet.
Weed beet of SMART varieties can not be controlled with CONVISO^® ONE or classic herbicides.

How can I distinguish between SMART KWS and classic seed?

SMART KWS seed has a purple inner pelleting mass whereas classic KWS sugarbeet seed is grey on the inside. Both pellets are orange on the outside

Never mix classic seed with SMART KWS seed.
