BNoting that the sowing is over, but also that the fruit is in bloom, we asked Milan what it is most profitable for farmers to do about the problems that arise at this time of year, both in terms of results and also of finances.
The vine is in the stages when the green leaves of the leaflets are clearly visible (Chardonnay, Cabernet, Sauvignon) to the stage when two to three or four leaves are developed (Frankovka, Hamburg, Riesling, Lasta).
During this period, the eryophid mites are activated (Calepitrimerus vitis, Colomerus vitis), which hibernate under the buds of the buds. At the beginning of the vegetation, they inhabit the first green parts of the new owner.
In order to prevent the appearance of gals, we recommend the use of preparations Amon 020 EW 1.2 l / ha, twice every 7-10 days. Subsequent treatments have weaker effects.
Apple is in different stages of flowering.
In some plantings, the presence of thrips was found during the examination of the flowers. Since the use of insecticides is prohibited during this period, keep this in mind at the boiling stage.
Due to announced local rainfall, protection and prevention of infection continues V.inaequalis. For flowering treatment, we recommend the use of Niveral 1 l / ha + Ciprodex 1 l / ha and foliar nutrient Wuxal Ascofol 1.5-2 l / ha.
Examination of the leaves of the apple (especially the red variety) also revealed a large number Panonychus ulmi. Given that we had a mild winter, with little rainfall, we can expect cobwebs in most of the plantations. For their suppression we recommend preparations Amon 020 EW (2x), Acrimite, Kanemite.
Blueberries is in the stage of 30-40% of the flowers open.
Since this fruit species has successive flowering, two and sometimes three treatments are required to protect this phase. We recommend the use of Asseria, Teldor 500 SC or Signum combined with Wuxal Ascofol.
Bone fruit is in the flowering phase.
The newly formed leaf mass is susceptible to infections by the causative agent of bone marrow leaves (Stigmina carpophila) i plum burners (Polystigma rubrum). In this phenophase it needs to be applied Merpan 80 WDG 2 kg / ha or Mankosav 2.5 kg / ha. If thrips are present, now is the time to suppress them and prevent early damage.
Depending on the altitude, raspberries are in the stage of intensive leafing until the development of the genital branches.
Everest 4 l / ha provides protection against tree diseases and bacterial infections, a Amon 1.2 l / ha of eriophid mites. In order to protect against insects apply Bifenicus 0,5 l / ha or Fastac 10 EC 0.25 l / ha. He turned out very well at this stage Wuxal Ascofol 2 l / ha.
Strawberry is in the stage of flowering start to full flowering. For protection against the entire spectrum of the parasite, apply Signum 1.8 kg / ha or a combination Decade 1l / ha + Image 0,5l / ha. To combat aphids your use Sivanto prime 0.5 l / ha. In case of dust mites apply Acramite in the amount of 0.25 l / ha. During this period use Wuxal Boron 2 l / ha.
For all other cultures, their protection, condition in the field, as well as treatment recommendations, you can look into the interview here.
