What tool should be used to help the plant fight fungus and pests
Copper sulfate is a reliable, time-tested remedy. If you process the plant in whole courses (in autumn and winter), then the remedy will help eliminate the possibility of developing dangerous diseases and avoid the death of the bush.
What are the advantages and disadvantages of using copper sulfate
The advantages include, first of all, an affordable price. You can buy copper sulfate at any agricultural store or order it online.
The drug is not toxic to humans, which is important for domestic use. It differs from others in its high efficiency in the fight against fungus.
The drug does not change the quality of the soil and stimulates the growth of crops, increases the plant's immunity to diseases. Acts externally, without penetrating cells.
The disadvantages include the ineffectiveness of the agent as an insecticide. Copper sulfate is limited in use (it is recommended to use it in the fall and early winter). The drug is capable of destroying the green mass of the plant (leaves may turn yellow during use in spring). When working with copper sulfate, it can be difficult to find the required concentration. And the last drawback is that after precipitation, the drug completely stops working.
How to use correctly
For a more noticeable effect in the fight against fungal diseases, plants are sprayed with a 3% solution. This must be done carefully and on dry days so that the solution dries on the leaves. Plants need to be re-processed only if it rains.
If the plant is not treated in the fall, then it can be done in the spring, but this time it is necessary to use a 1% solution.
To prepare a 3% solution in 10 liters of water, add 30 grams, for 1% - 10 g. Copper sulfate must completely dissolve in water, after which the prepared liquid can be used. The finished composition must be applied immediately, since copper sulfate loses its properties upon contact with air.
It fights well against fungal plant diseases such as rust, spheroteka, septoria and others. Also, the fungicide performs well in the fight against insects. To treat the plant against pests, the agent is used in the fall, before covering the rose for the winter.
Copper sulfate is also used as a fertilizer. It is necessary to dissolve 10 grams of the drug in 10 liters of water, taking into account the fact that this volume must be sprayed on an area of 100 squares. Watering should take place in dry, calm weather. Remember, this technique is not used during the summer season.
With this tool, you can protect your plant from fungal diseases, as well as protect it from pests and fertilize the flower well for the winter. The main thing is to clearly adhere to the listed rules and monitor the reaction of the rose itself.
