Plant protection activities in the orchard in June

In June, the forecasted frequent rainfall is a prerequisite for the development of fungal diseases - late brown rot, scab and powdery mildew on fruit trees. More suitable conditions for carrying out plant protection sprays will be created in the second half of the month.

In fruit nurseries

The fight against diseases and pests continues in nurseries, seedbeds, and stock blocks with clonal and quince rootstocks. Apple and pear nurseries and stock blocks are sprayed with a copper preparation -1% Bordeaux mixture, Funguran OH 50 WP - 150-250 g/dka, Champion WP - 0.3%, Kaper Key – 180-300 g/dka  against scab and against leaf-eating insects and aphids. Spraying continues until growth is complete.

Powdery mildew – apple

Apple and peach varieties sensitive to powdery mildew and clonal apple rootstocks are sprayed every 8-10 days with a sulfur-based preparation - Sulfur WG 600 g/dka, Solfo 80 WG – 750 g/dka.

Cherry and sour cherry varieties, Mahaleb rootstocks are sprayed every 8-10 days with Silit 544 SC – 125 ml/dka against cylindrosporiosis.

Clonal quince rootstocks and pear seedlings in seedbeds are sprayed with a copper preparation - 1% Bordeaux mixture, Funguran OH 50 WP - 150-250 g/dka, Champion WP - 0.3%, Kaper Key – 180-300  against brown leaf spots at an interval of 10 days until growth is complete.

In the presence of California red scale and white American butterfly, spray with a pyrethroid insecticide respectively – Decis 100 EC - 7.5 -12.5 ml/dka, Sumicidin 5 EC (0.02%), Aphicar 100 EC (15 ml/dka), Efcietrin 10 EC (15 ml/dka) and Dipel 2X (0.1%). The caterpillar nests of the white American butterfly are cut out and burned.

In fruit plantations

Poisonous trapping bands are placed to destroy the second generation caterpillars of the plum fruit moth.

Plum fruit moth

Fallen worm-eaten fruits – apples, pears, plums, walnuts – are collected to reduce the density of the second generation of fruit worms.

Pheromone traps are placed to catch fruit moth butterflies, in connection with determining the timing for spraying against their second generation.

Non-poisonous trapping bands are inspected to determine the start of flight of the second generation fruit moth butterflies. 2500-3000 apple fruits of different varieties, collected from several trees scattered in the plantation, are examined to determine the infestation and the need for spraying against the second generation of the apple fruit moth. If the infestation is less than 2%, spraying is not carried out. Fallen worm-eaten fruits are collected and destroyed to reduce the density of the second generation of fruit worms.

Worm-eaten hazelnut fruits are collected and destroyed to reduce the density of the hazelnut weevil.

Observations are made to determine the first rust spots on plums, on the development of leaf-mining moths, mites.

The survey of fruit plantations continues to detect trees infected with viral diseases and mark them.

Poisonous baits are placed (potatoes, carrots or other vegetables soaked with Actellic 50 EC, Biona Sincar - 4 l per 1 kg) or Mesural Schneckenkorn (250 g/dka) is buried. With a small shovel or pincers, the bait is placed in the tunnels of the mole-rat.
