Long rains, dampness and fogs are favorable conditions for the appearance and reproduction of a parasitic fungus. With the advent of spring, the virus attacks young leaves and covers the entire plant. If you start the disease, you can lose almost the entire crop. Timely prevention is the best method of dealing with pathogenic fungi that affect shrubs and fruit trees.
Among gardeners, the fungicide Polyram has gained confidence, which has a wide range of applications. Let’s get acquainted with its features, instructions for use and reviews of summer residents.
Features of the fungicide

Each gardener must weigh all the advantages and disadvantages of fungicides and, depending on the purpose of use, choose the most suitable one for himself.
Preparation of working solution
Preventive spraying with Polyram begins in early spring at the beginning of the growing season. For the whole season, 4 pulverizations are carried out with an interval of 8 to 10 days.
The working fluid of the fungicide should be prepared on the day of application, as it loses its properties during storage. To do this, the sprayer is half filled with water and the granules are dissolved in it. Then, stirring constantly, add the liquid to the desired volume. The result should be a homogeneous solution. The dose of Polyram and the processing time are selected depending on the type of culture.
Potatoes
Potato beds can be affected by late blight and Alternaria in many regions of the country. Diseases cover both bushes and tubers. Yield losses can reach up to 60%. Fungicide Polyram will help protect the plant from these fungi.
To prepare the working fluid, 40 g of dry matter must be dissolved in 10 liters of water (bucket). Potatoes are sprayed four times: before the tops close, during the formation of buds, after flowering and during the appearance of berries. The instructions say that the Polyram fungicide retains its effect for three weeks. An average of 50 ml of solution is consumed per square meter.
Tomatoes
Tomatoes are also vulnerable to alternariosis and late blight. Saving infected plants is very difficult. Most of the crop will still die, so preventive procedures should be given special attention.
To provide plants with reliable protection against pathogens, 40 g of Polyram fungicide must be diluted in 10 liters of water and the bushes should be carefully treated. Pulverization is carried out three times with an interval of 19-20 days. Consumption – 40-60 ml per 1 m2.
Grapes
The most harmful grape diseases are anthracnose and mildew. If you are too lazy in the spring and do not carry out preventive procedures, you can be left without a crop. Polyram fungicide is excellent for processing grapevines.
The working fluid is prepared from 25 g of the drug and 10 liters of water. According to the instructions for use, the vineyard is sprayed four times: during the formation of inflorescences, after flowering, during the appearance of berries and when the fruits reach 50 mm. 1 m2 on average, 90 ml of solution will be required. The protective effect of the fungicide lasts 20 days.
Fruit trees
Fungicide Poliram is widely used for the prevention of rust, scab and septoria, which usually infect pears and apple trees.
First, the solution is mixed: 20 g of granules are poured into 10 liters of water and stirred until the particles dissolve. During the entire growing season, the orchard is sprayed four times: leafing, buds appearing, after flowering and when the fruit reaches a diameter of 40 mm. Depending on the size of the fruit tree, it consumes from 3 to 7 liters of working fluid. The protective effect of the fungicide lasts 37-40 days.
Compatibility with other drugs
Polyram fungicide must not be mixed with substances that have an acid reaction. It can be combined with pesticides Acrobat, Fastak and Strobi.
Before mixing the tank solution, each preparation should be checked for compatibility with Polyram fungicide. If sediment has fallen to the bottom, these substances cannot be mixed.
Safety Precautions
Fungicide Poliram belongs to the 2nd hazard class. It is harmful to humans, but does not have a toxic effect on plants. The drug settles on the surface of the plant tissue and is washed off with water. Avoid contact with water bodies.
