During this period, the vines are from phenophase “full flowering” to phenophase “pea-sized berry” - “cluster closing”

Main pests for the period

Downy mildew of grapevine Plasmopara viticola

Powdery mildew Oidium tuckeri

Grey mould Botrytis cinerea

European grapevine moth Lobesia botrana

Vine scale  Pulvinaria vitis

Yellow vine mite Schizotetranychus viticola

Grey mould

In the phenophase “full flowering”, brown spots are formed on the flowers and flower stalks, which are covered with the sporulation of the pathogen. These symptoms are known as early grey mould.

Strategy for pest control: In rainy and warm weather, immediately after flowering, at the appearance of the first berries and at cluster closing, spraying is carried out with one of the registered plant protection products.

European grapevine moth

In June, the butterflies of the second generation of the pest are flying. They lay their eggs on berries of pea size (first berries). The larvae damage the first berries by gnawing and eating out the inside of the berries together with the seeds. The damaged berries are weakly bound with silk threads. One larva damages from 7 to 24 berries.

Strategy for pest control: Treatments should be carried out at the ETL: for table grape varieties 6-7 larvae per 100 first berries, and for wine grape varieties 11-12 larvae per 100 first berries.
