- The prepared solution cannot be stored for a long time.
- The high cost of one package weighing 5-6 kg.
Consumption rate for different plants
Despite the fact that exceeding the norm does not have a detrimental effect on the treated crops, the amounts indicated in the table should be adhered to.
|Culture||Disease||Consumption per one hundred square meters g / 10l||Protection period in days||Last treatment before harvest in days||Multiplicity of treatments|
|Grapes||Mildew and other diseases||35||21||50||3|
Working solution preparation method
To make a working solution, you will need settled water at room temperature. To process one hundred square meters of landings you need:
