Tanaris® and Topkat® in sugar beet
Sugar beet herbicides in 2021
The loss of desmedipham means that growers and advisors will need to re-think their herbicide programmes. However, good weed control can still be achieved without desmedipham, through the appropriate choice of active and dose rate, according to the weeds present, weather conditions and the effect of previous sprays.
The use of Tanaris® and Topkat® provides a useful addition to post-em herbicide mixtures, not least because they're the only products that deliver the active, dimethenamid-p, in sugar beet.
- Co-formulation of dimethenamid-p (DMTA-p) and quinmerac
- Two actives increase reliability through multiple points of entry
- Contact and residual activity against late weed flushes
- Post-em only with good activity on crane’s-bill, cleavers, poppy, dead nettle, speedwells and fool‘s parsley
- Flexible mixing partner to standard sugar beet herbicides e.g. mix with ethofumesate, phenmedipham or metamitron containing products to control a wide spectrum of blw
- Tanaris® and Topkat® activate the partner - there's no need to add oil when Tanaris® and Topkat® are added to the mix
Weed spectrum
Post-em only
- Maximum of three post-em applications at rates according to crop growth stage (do not exceed maximum total dose)
- Minimum interval of 7 days between applications of Tanaris® and Topkat®
- Optimum results are obtained when weeds are at the pre-em or cotyledon stage at application
- Good efficacy is obtained through uniform wetting of the weeds and sufficient, available soil moisture
- Use in mixture with other herbicides to control a wider range of broad-leaved weeds
- Under dry conditions, it is advised to increase the water volume
Water volume
- Tanaris® and Topkat® can be used at lower water volumes (e.g. 100 l/ha water) without having to reduce the dose rate
- For further details please refer to the Technical Bulletin “ north_east BASF products and Reduced volume spraying”
Water stewardship guidelines
- Quinmerac is subject to a Water Stewardship Programme
- Follow VI and BASF best practice guidelines to protect water when using this or any other product containing quinmerac
- Reduce the risk by ensuring that at least 6 of the following criteria are met to significantly reduce the risk to water
1. Soils are moist and NOT dry, cracked or saturated
2. Field drains are NOT flowing and are unlikely to flow within 7 days of application
3. Field slope is less than 5% (a 5% gradient is 1 metre fall in 20 metres)
4. The field is NOT bordered by a watercourse
5. The field has a 5m no-spray zone or 6m grass buffer strip adjacent to water
6. The field has NOT been deep sub-soiled (below plough layer) in the preceding 6 months
7. Spring cultivations are no deeper than 20cm or previous ploughing depth, whichever is the greater 8. There is NO risk of heavy rainfall within 48 hours of application
