  • CONVISO® SMART seeds available from KWS seed company
  • CONVISO SMART varieties allow the control of weeds in sugar beet by the application of a product named “Conviso® One” that contains two ALS inhibitor herbicides (floramsulfuron 50g/l + thiecarbozone 30g/l) formulated as an oil dispersible formulation (OD).
  • Conviso® One provides control of many broadleaf and grass weeds but. has limited control of one very important, weed in sugar beet: Chenopodium album (CHEAL).
  • Conviso® One herbicide label recommendation for the control of CHEAL indicates either a single application at 1 L/ha or two applications at 0.5 I ./ha to be applied no later than the 2-leaf growth stage of CHEAL.
  • florpyrauxifen-benzyl e.g., RINSKOR® active ingredient
  • Florpyrauxifen-benzyl is an auxin-mimic herbicide which provides excellent control of CHEAL
  • Florpyrauxifen- benzyl may be applied up to four times and is effective against CHEAL from 2-leaf to 6-8 leaf stages of growth. Florpyrauxifen-benzyl provides excellent control of CHEAL along with application timing flexibility and application dosage flexibility allowing effective control of CHEAL in CONVISO® SMART sugar beets.
  • Florpyrauxifen-benzyl has been tested in field trials on conventional sugar beets and on CONVISO® SMART ALS-resistant sugar beets. Surprisingly, fiorpyraxuifen- benzyl demonstrated selectivity on CONVISO® SMART sugar beets, even though the florpyraxuifen-benzyl mode-of- action (auxin mimic) is unrelated to ALS. Flor- pyrauxifen-benzyl was safe on certain conventional sugar beet crop varieties and damaged other varieties. Florpyrauxifen-benzyl was safe on CONVISO® SMART sugar beets at doses from 0.5 g ae/ha to 4 g ae/ha under field conditions.
  • sugar beet refers to a plant of the species Beta vulgaris subspecies vulgaris var. Altissima whose root contains a high concentration of sucrose.
  • Sugar beet plants and crops may be species, and/or hybrids, and/or genetically modified.

  • weeds refers to any unwanted vegetation that may interfere with the growth and/or harvesting of a desired crop. Weeds are known to compete for nutrients with crops such as sugarcane, lowering yields. In addition, weeds may interfere with mechanized harvesting machines, lowering harvesting efficiency. Weeds include, but are not limited to, the following: CHEAL ⁇ Chenopodium album. Common lambsquarters), STEME (Stellaria media, Common chickweed), LAMAM ( Lamium ample. xicaule, Henbit), FUMOF (Fumaria officinalis.

  • a “herbicidally effective amount” or “vegetation controlling amount” or “weed controlling amount” is an amount of active ingredient(s) which causes an adversely modifying effect to the vegetation, such as a weed, causing deviations from natural development, killing, effecting regulation, causing desiccation, causing retardation, and the like. These terms may be used interchangeably.
