Some remarks on the use of Brevis
- Only spraying on the top of the tree is possible
- Brevis should always be sprayed on a dry crop.
- Brevis can be sprayed with 200 to 300 l of water/ha.
- The temperature at the time of application does not play a major role.
- Do not apply in case of uncertain weather or after severe frost damage, because Brevis has a strong effect on fruits without seeds.
- The highest allowed dose in Belgium is 2 x 2.2 kg/ha, but this dose will not be used because this will cause in many parcels an overthinning
- Do not add foliar nutrition or other products because they can enhance the thinning effect.
