Observations of Use
The use of Lithovit in viticulture in 2007 showed positive effects on plant health and reduced susceptibility to disease. Depending on the vineyard concerned and the facilities available for analysis, the harvest produced a larger mass of grapes through larger individual berries or higher sugar content of the must.

Recommendations For Use
0.5% suspension with 1.5 kg per ha and application, at least 3 applications:
- at the beginning of flowering (BBCH* 61),
- as the fruit begins to develop (after BBCH* 71),
- when berries begin to touch (BBCH* 77).
* The BBCH scale is a scale used to identify the phenological growth stages of a plant: see the website of the Federal Biological Research Centre for Agriculture and Forestry (www.bba.de/veroeff/bbch/bbcheng.pdf)
