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
