During this period, the vines are in the phenological stage from “end of flowering” to “beginning of berry ripening”  in the early varieties.

Powdery mildew Oidium tuckeri

Grey mould Botrytis cinerea

Bacterial cancer Agrobacterium  vitis

European grapevine moth Lobesia botrana

Vine moth Theresimima ampellophaga

Bacterial cancer

In infected plants on the lignified parts, close to the soil surface or immediately below the soil surface, swellings (tumours) are observed. Diseased plants show suppressed growth, chlorotic leaves and are easily winter-killed  during a cold winter.

Strategy for pest control:

In July, vines showing symptoms of the disease must be marked.

Vine scale

Larval hatching continues during the first half of July. They cause damage by sucking sap from the leaves, shoots and grape clusters. They moult once, feed for a certain period, then leave the feeding sites and move to their overwintering locations. As a result of the damage, the vines become weakened.

Strategy for pest control:

Chemical control is carried out against the young larvae.
