The weather last season was good for the vineyard. But despite this, many years turned out to be a failure. Now we need to work on the mistakes so that the failure does not happen again. By the way, if you are not too friendly with fungicides, then choose varieties that are resistant to disease, and not those that have the best bunches. But if you grow grapes for sale on the market, then you can not do without spraying.
Kyiv. Ukraine. Ukraine Gate – April 29, 2021 – Agriculture
On capricious varieties, do not wait for the first signs of disease … Destroy them with preventive spraying. That is, the grapes are not sick, and it is still necessary to spray.
First of all – the diagnosis
To determine exactly which medication to use, you need to make a diagnosis. What about the bushes, you will tell the actual grapes. You just need to know his signals.
Remedies can be found in garden stores.
We correct mistakes
If the grapes are sick and you did not do the eradication spraying in the fall, do so in the spring immediately after opening. It is important to have time to bud burst. Both vines and soil should be treated. Dosages all give different, from 300 to 700 g, you can use 300-400 g of iron sulfate per 10 liters of water.
Do not be afraid after spraying – the vine turns black due to iron oxidation, this is normal. Sulfur will destroy mold and fungi on the surface of the vine, but their spores will remain in the buds, and when they dissolve, the spores will begin to germinate.
Here everything is simple: when three or five leaves appear, you can spray the grapes with a mixture of Acrobat MC and Topaz, and if you are tired of ticks, you should also use Fufanon.
Be careful: after flowering buds, vitriol can not be used. They are not harmless at all, can burn the leaves if you make a mistake with the dosage.
Equally important is the fact that after the application of vitriol buds will wake up a week later. Such a delay is in our favor – a minute of spring frosts.
The treatment must be repeated before and after flowering. Trovit Jet or Cumulus + HOM or Abiga-Peak are already suitable here.
A spoon is appropriate for dinner
Leaf fertilization is very useful, but between spraying many growers do not have time to make them, summer days are not enough. Trace elements can be added to fungicides, they are not only useful but also enhance the effects of poisons. We save time, feed and protect the grapes – and all this with one spray. Useful and practical.
