Harmful insects are not only capable of depriving you of your grape harvest, but also causing significant damage to plants, leaving behind microcracks and wounds through which pathogens enter the grapes, and they begin to get sick.
The first thing you should do if you decide to use chemicals to combat grape pests is to carefully read the instructions provided.
However, there are also general rules for using such means.
So, spraying is usually carried out on leaves and stems on a windless day.
The ideal time for the procedure is in the morning before 10:00 and in the evening after 18:00.
If you stick to the specified time range, the risk of your grape vines getting sunburned is reduced to zero.
Important: if chemicals were used to treat the vineyard, harvesting will have to be postponed.
The exact information about the number of days marked “waiting period” can be found in the instructions for the drug.
