July in the vineyard

 

In 1910 in July, work in the vineyard was marked by light tillage, various work in green, treatments against diseases and parasites, and finally monitoring the phenomenon of cavitation due to high heat.

 

 

Here is what can be read in the Wine Trade Directory from 1910 :

 

Culture – Immediately after flowering, superficial hoeing is necessary.

We finish tying the branches of the wood branch; we trim at the height of the stalk all the branches that we have just tied. We visit the grafts to remove suckers (1). Finally it is useful to repeat the ways of summer frequently.

Folletting (2) is an accident determined by a sudden and strong evaporation of the waterlogged leaves, then suddenly subjected to the action of the sun. There is no known cure for folleting. Only drainage can reduce the chances of harm by regulating the humidity conditions in the environment. It is advisable to uproot and replace severely affected vines; because they hardly regain their vigor.

Pest control – Use celestial water (3) against caterpillars and the borer that has passed into perfect condition. In the first fortnight of the month make a treatment against mildew and burps, fight anthracnose. During the second fortnight, third treatment against powdery mildew and sometimes, at the end of the month, new treatment against mildew.

 

 

Nowadays in July

 

The works are similar: carrying out phytosanitary treatments to protect the vine from diseases and pests and proceed to the topping of the twigs. The latter, promotes sunshine and aeration of the bunches, improves the ripening of the grapes, the passage of tractors and also helps maintain the upright shape of the vine.

 

 

(1) The suckers are shoots coming directly from a root of the vine.

(2) Folletting is also called gas embolism or cavitation. This phenomenon causes, at first, the drying of the old leaves, and can go until the death of the foot if it is very severe.

(3) Heavenly water takes its name from its blue color, it is a preparation used for the treatment of vine foliage obtained by mixing ammonia and copper sulphate. Heavenly water is the basis of Burgundy porridge, itself, composed of soda ash and copper sulphate to treat vines against mildew.
