Spreading and budding

• Procedure  : removal of non-fruiting branches in the stump head (splitting = disbudding) or on the basis of the trunk of the stump (suckering)

• Phytosanitary interests :
  • Limit the accumulation of vegetation
  • Limit the onset of late blight epidemics (suckering) 

• Interests of the technique :
  • Foliage aeration
  • Optimize photosynthesis
  • Limit working time
  • Limit competition with grapevine
  • Facilitate the passage of machinery

• Induced effects :
  • Limit the development of vegetative organs which constitute sap sinks
  • Aerate the stump
  • Limit grass cover in the row (case of certain mechanical root suckers)
  • Limit the risks of phytotoxicity from systemic herbicides (in the event of weeding under the row)
  • Limit DF leafhopper populations
  • Risk of promoting the development of mites on certain grape varieties due to the dust raised by the scumprous plant
