Preparation of working solution and its application
According to the instructions for use, the Rex Duo fungicide must first be diluted in a small amount of water. The consumption rate of the substance depends on the type of crop and disease. When the drug dissolves, you can add more water to the required volume. The finished working solution is poured into the sprayer and used within a day. It cannot be stored, as it then loses its effectiveness.
Cereal crops are sprayed only once per season. Sugar beet can be processed twice, but with a break of at least two weeks. Plants are sprayed at least twenty days before harvest.
It is best to process crops early in the morning or in the evening in calm weather. The optimum air temperature at the time of spraying is from +12 to +25 degrees.

To cure crops (barley, winter and spring wheat) from diseases such as septoria, rechosporiosis, pyrenophorosis, all types of rust and spotting, as well as powdery mildew, it will take from 0.04 to 0.06 ml of the substance per 1 sq. m. Spray the plants once a season during the growing season. The substance remains active for thirty days.
Sugar beets from cercosporosis, powdery mildew and ramulariasis are sprayed for preventive purposes during the growing season. Upon detection of repeatedsymptoms of the disease spraying is repeated. Consumption rate of fungicide per 1 sq. m in this case is from 0.05 to 0.06 ml. The duration of the drug is 21 days.
For spraying peas from ascochitosis and gray rot, you need 0.06 ml of "Rex Duo" per 1 sq. m. Processing is carried out during the growing season. The activity of the substance persists for twenty days.

Fungicide "Rex Duo" can be used for complex treatment of plants along with other protective substances and liquid fertilizers. The drug is considered compatible with others. However, it is worth checking before using the tool. To do this, take a little of each of the components and mix in one container. If a precipitate appears, then the substances are incompatible.
