Jakou máte zkušenost s dobou aplikace přípravků proti kadeřavosti?
_________________________________
I read an interesting article about leaf curl disease (sorry, only in Czech) which indicates that the choice of the agent (the product against the leaf curl disease) is unimportant compared to the period WHEN it is applied. The study reveals that the best period when the application shall take place is when the temperature is above 7° for at least 70 hours (or, at its best, 100 hours). This period differs year from year (from February to April, according to the study) and, naturally, it depends on the location. If you are interested, just write me and I will translate the defined part of article for you.
Have you found the best time for the application against the leaf curl disease?
