June in the vineyard2 June 2020
“Vineyard and cellar – 1910” is a series of articles that we present to you throughout the year 2020, month by month. The articles are taken from the 1910 “Wine Trade Directory” and describe the various works necessary for the grapes and wine production at the beginning of the 20th century.
In 1910 in June, work on the vineyard was marked by green work and tillage, and phytosanitary protection treatments.
Here is what can be read in the Wine Trade Directory: Cultural care – When finishing the third plowing, care must be taken not to damage the vines in bloom. New plantings are weeded (1) in order to stop the weed vegetation and cut the soil. In the vines in full relationship, immediately after flowering, the second disbudding is practiced, to avoid the diversion of the sap in favor of useless wood. We will finish the training and we will make a second tying without tightening the link too much.
Defensive care – Regularly, the first treatment for powdery mildew, mildew and anthracnose is carried out in early June in northern and central vineyards. At the beginning of the second fortnight, a second treatment with sulfur is made against sulfur, coinciding with flowering. In the last days of the month a new treatment is carried out against mildew and burping (2) in the Midi and in the Southwest. It will also be necessary to fight against animal parasites, and for this purpose carefully remove the leaves from the base of the oaths on which the flea beetle larvae stand; give chase to gribouris, harnesses or cigar makers, (3) etc.
Nowadays, green operations such as budding and trellising of the vine are still in use today. Treatments against cryptogamic diseases also used.
The disbudding is the operation which consists in eliminating the buds emerging from the vine if they are too numerous. Because, as explained in the wine trade directory, the plant would use energy “for the benefit of useless wood”. This operation will ventilate the foot, which will be beneficial in limiting cryptogamic diseases, but also in limiting the number of clusters produced by the foot and therefore having optimal maturation of the remaining clusters.
(1) Weeding means removing weeds with a tillage tool.
(2) Burls are cryptogamic diseases of the vine, that is, diseases caused by microscopic fungi, such as downy mildew and powdery mildew.
(3) Altise, Gribouris (or Writer), Attelabes and Cigarières are all pests of vineyards.
