| This concerns a movement against the use of too many insecticides and fungicides. The aim is to employ them in a rational manner and to select, dose and apply such products as intelligently as possible.
Diseases affecting the vine were brought to Europe from the Americas in 1860 (eg. Mildew, powdery mildew and phylloxera). Growers were forced to use ever-increasing amounts of insecticides in their attempts to combat these diseases.These products were essential to the health of the vine and to ensure that the healthy grapes realized their full potential. However, for maximum protection they had to be employed regularly and systematically, thereby eliminating the predators of insects and other parasites whilst at the same time weakening the vine. Moreover, these applications had a negative effect on the environment.
Some years ago, the Cave de Pfaffenheim took the decision to use these products only when and where absolutely necessary. Our growers monitor the development of the disease to assess whether treatment is absolutely necessary. They determine the amount to be used and how each product is to be applied.
This movement towards more rational growing techniques also involves allowing grass to grow between the rows of vines, avoiding excessive tipping and pruning back of summer shoots, banning the use of highly toxic products and separating the bunches one from the other in order to avoid rot. |
