Fungicides for cucumbers: Pervikur, Infinito, Allette, Hom and Bordeaux mixture

To combat fungal diseases of cucumbers, chemicals are used that can prevent infection of plants. Allett, produced by the German company Bauer, belongs to the universal fungicides of protective and therapeutic action.

There are a lot of preparations of such multipurpose use on the market of modern pesticides. They can be used to treat the aerial parts of plants, disinfect soil and seeds, and for preventive purposes. The systemic method of fungicide exposure allows you to protect and treat plants in the open field or greenhouse, regardless of weather conditions.

Important! The advantage of protective fungicides is the direct economic benefit.

Often, gardeners do not have the opportunity to regularly inspect cucumbers in a greenhouse or greenhouse. Clear signs of fungus invasion become apparent when a hard-to-recognise disease has successfully taken over the cucumber bush. Its presence poses a threat of infection to other plants. In this case, much more resources will be required to protect the cucumbers and save the crop. And the source of infection can be poorly prepared seeds, soil, greenhouse frame.

There are many reasons, so the use of fungicides is often an ordinary agricultural technique for caring for cucumbers. Consider some of the drugs without bias, because pesticides have long become the norm for agricultural enterprises and farms.

Cucumber disease control agents

Cucumbers are most often grown in protected ground, where stable colonies of fungi form in a closed space. Fungicides, which are used to treat plants without waiting for obvious signs of disease, help protect plants. In a home greenhouse, this is done quite simply. Several times during the growing season, it is enough to sprinkle the leaves or water the bushes under the root.

• Bordeaux liquid is considered the first fungicide that was used to protect agricultural plants. A mixture of copper sulfate with lime water successfully resists most fungal diseases. Copper acts as a toxic substance, and lime neutralizes the effect of acid on the plant. As a result, the Bordeaux mixture is successfully used as a prophylactic against the fight against pathogens of pathogenic microflora.Cucumbers are treated with 1% Bordeaux mixture at the stage of 2-3 true leaves, followed by a repetition of treatments after half a month. The last procedure during the fruiting period should be carried out no later than a week before harvest.
• Hom - copper oxychloride, a fungicide that has become a substitute for Bordeaux mixture. Unlike her, Hom is easy to prepare. The finished powder is diluted with plain water and used for spraying plants. The drug does not hold well on the surface and is easily washed off by rain. Cucumber is a greenhouse crop, so the fungicide is great for its treatment in greenhouse conditions. The question is logical, is it possible to treat cucumbers in the open field with the drug. Of course, only in dry, calm weather. Hom is a contact fungicide, it acts on the surface of the plant without penetrating into its cellular structure and combines well with other pesticides. Spray the plants with hom during the growing season, with an interval of 10-15 days. All this time, the fungicide continues its action, subject to the rules of agricultural technology.Disinfection of plants should be carried out 20-30 days before harvest.
• Sumilex is a chemical preparation of protective and healing contact action. Accumulating in the young parts of the plant, it inhibits the development of mycelium and the germination of white and gray rot fungi. Available in the form of a wetting powder, which is combined with chalk or lime during manufacture. The resulting mixture is coated with the affected areas of the stems of cucumbers growing in protected ground.

• Fundazol is used for dressing seeds, as a prophylactic and therapeutic agent for the plants themselves. Demonstrates the therapeutic effect of Fundazol only the first three days from the moment of treatment. Further, within two weeks, the drug Fundazol demonstrates its protective abilities. As it decomposes, the active substance moves inside the plant from the root to the top. In addition to the fungicidal effect, Fundazol resists most pests, which include aphid larvae, leaf beetles and spider mites.Fundazol is used as a solution. They pickle seeds, shed roots, spray stems and leaf axils. The preparation and use of the drug should be carried out strictly according to the instructions. This fungicide belongs to the third category according to the degree of danger.
• Strobi fungicide is a very strong therapeutic and protective drug. Effectively stops the growth of mycelium and sporulation of fungi. The plant is sprayed with a working solution every two weeks. The last time you can spray cucumbers is a month before harvesting. The result of processing appears after a couple of hours. The drug, unlike other fungicides, can be used at low temperatures up to +1 degrees, on wet foliage and during flowering. The drug treats a number of cucumber diseases, including downy mildew.
• Topaz is a remedy for a number of fungal diseases. It can be used as a prophylactic and therapeutic drug. Topaz has a high impact rate.In just 3 hours, the growth of mushroom mycelium stops. Topaz continues to protect plants for 14-18 hours. Preventive treatments are carried out at the beginning of the growing season every 10-15 days. Topaz has a low consumption rate, is quickly absorbed, and is well combined in mixtures with other pesticides. Topaz is suitable for preventive and therapeutic treatments of cucumbers in unprotected ground, is well tolerated by plants, and is not toxic to birds and insects.
• Quadris is a preventive and he alth-improving drug, a highly effective fungicide used to treat diseased plants. Quadris can be used in protected and open ground, in joint treatments with other pesticides. It is not recommended to use herbicides with it. When processing, it is necessary to monitor the complete coverage of the leaf surface with the working mixture. Quadris is used during the growing season, before flowering, at intervals of 10-15 days. The eradicating effect of Quadris begins within a few hours, and the preventive effect lasts up to three weeks.It is not recommended to use Quadris in personal subsidiary plots.

Regardless of the reliability of the manufacturer, when using fungicides, it is always necessary to carefully study the instructions and strictly adhere to them. Do not prepare more solution than necessary. Spray the plants, then thoroughly wash the container. Stay safe.

Important! Many drugs are very toxic, dangerous even to humans.

Modern drugs from Bayer

A company with a solid history is constantly creating innovative products in the crop protection market. German products have earned excellent reviews from farmers for their reliability and efficiency.

For prevention purposes, Previkur Energy is used in the following order:

• Initially, immediately after sowing the seeds, soil treatment is carried out;
• after the cucumbers begin to grow and form the first true leaves, Previkur energy is used for root watering;
• following watering is carried out in two weeks, the lower stems are processed;
• if the plants show signs of infection with a fungal infection, then Previkur energy in the form of a solution is applied by spraying to the affected areas.

Alette is a drug with a contact-systemic effect. In just half an hour, the active substance of the fungicide penetrates into the tissues of the plant and affects the intracellular biochemical processes. As a result, the plant develops immunity. The action of the drug Alett lasts up to 30 days and its effectiveness increases after repeated treatments with an interval of 10 days. Allett exhibits a therapeutic effect if used one day after signs of plant infection are detected. The fungicide is effective as a preventive drug during the active growing season.
