Scientists all over the world are puzzled by the creation of progressive protective drugs for various cultures. Constantly in this area are made new and new discoveries. Every year pesticides are becoming more efficient, and their negative impact on the environment is gradually decreasing. One of the drugs of the new generation is the fungicide "Merpan," which is designed to protect the apple trees.
Composition and release form
The main active ingredient is captan. Its content in the preparation is 800 g / kg. This substance belongs to contact pesticides, which, in turn, belong to the chemical class of phthalimides.
The drug is presented in the form of granules dispersed in water. Most often packaged in plastic bags of 5 kg.
Important! People are allowed to work in the garden seven days after treatment with a fungicide. Mechanized works are allowed on the third day after spraying.
Benefits
The preparation for protection of apple trees "Merpan" has a number of indisputable advantages over other fungicides.
- It has a wide range of effects.
- It has a therapeutic effect within 36 hours after the introduction of the drug.
- There are high rates of preventive effects in the application of the fungicide "Merpan".
- Relatively safe for insects, birds and bees.
- It begins to act immediately after spraying, under favorable weather conditions, protection is maintained for 14 days.
- Differs in the minimum phytotoxicity, completely decays in soil and does not constitute danger to future cultures.
- The emergence of the resistance of pathogenic microorganisms to fungicide is impossible due to the unique mechanism of action.
- Able to protect both foliage and fruits on apples.
- Protects apples even after ripening and harvesting. It is noted that fruits treated with this fungicide are better stored.
- Compatible with many pesticides.
- Unlimited application area.
In the fight against pests and diseases of apple trees, they also use such fungicides as Abiga-Peak, Skor, Delan, Poliram, Albit, DNOC.
Operating principle
"Merpan" refers to a broad-spectrum fungicide, It is based on three main stages. First of all, contact with foliage and fruits disrupts the metabolic processes of pathogenic microorganisms, which subsequently leads to their death and eliminates the emergence of their resistance to the drug.
How to prepare a working solution
First you need to make a basic or mother liquor. For its preparation, a measured amount of granules is dissolved in 2 liters of water in a separate vessel. The mixture is stirred until complete dissolution.
Then it is necessary to inspect the sprayer tank, if it is clean and serviceable, it is filled with water. The resulting solution is poured into a filled tank and rinsed several times the container in which it was prepared.
Important! The solution must be constantly stirred, otherwise the substance may settle on the walls and bottom of the tank.
When and how to process: instruction
Processing "Merpanom" carried out in the early morning or late evening. Fungicide, according to the instructions for use, can be used throughout the growing season, but be sure to take into account that the final spraying of apple trees should be carried out for 30 days of the beginning of the harvest.
It is desirable to process the gardens at an air temperature of + 14-16 ° C, and the wind speed should be no more than 4 m / s. On average, use 1.5-2 liters of the drug to process 1 hectare of the garden, that is, you need to prepare 900-1600 liters of working solution per 1 hectare.
Spray the apple when the first symptoms of the disease appear and be sure to repeat the procedure after 1-2 weeks.
Did you know? Fungicides are divided into two groups: some protect plants, others treat. The drug "Merpan" is used both for the prevention of diseases and for their treatment in the initial stages.
Toxicity and safety measures
Fungicide is characterized as moderately dangerous. May be dangerous to fish and other aquatic creatures, therefore its use in the sanitary zone of water bodies is not recommended.
The use of protective agents for spraying trees is mandatory, given that the drug belongs to the 3rd class of toxicity. 
Storage conditions
Store "Merpan" in specialized warehouses for pesticides in sealed original packaging. The air temperature in such rooms can vary from -5 to +40 ° С. It is not recommended to store the fungicide at high altitude.
Care must be taken to avoid direct sunlight on the packaging. The warehouse in which the product is stored must be dry.
Did you know? Fungicides can be completely safe for humans and the environment - we are talking about biological alternative means designed to combat various diseases, which are characterized by the fact that the active substance is of plant origin.
Despite the fact that the fungicide is most often used to protect and treat apples, it is also used to combat fungus on soybeans, grapes and strawberries. The effectiveness of this tool was already appreciated by many farmers who successfully use it in gardens and fields.
