There are many drugs of similar multi-purpose use on the market of modern pesticides. They can be used to treat the above-ground parts of plants, disinfect soil and seeds, and for preventive purposes. The systemic method of action of fungicides allows you to protect and treat plants in open ground or a greenhouse, regardless of weather conditions.
Important! The advantage of protective fungicides is direct economic benefit.
Often gardeners do not have the opportunity to regularly inspect cucumbers in a greenhouse or greenhouse. Clear signs of fungal invasion become apparent when a difficult-to-recognize disease has successfully taken hold of a 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, or greenhouse frame.
There are many reasons, so the use of fungicides is often an ordinary agronomic technique for caring for cucumbers. Let's consider some of the drugs without bias, because pesticides have long become the norm for agricultural enterprises and farms.
Means for combating diseases of cucumbers
Cucumbers are most often grown in protected soil, where stable colonies of fungi form in a confined space. Fungicides help protect plants by treating plants without waiting for obvious signs of disease. In a home greenhouse, this is done quite simply. Several times during the growing season, it is enough to spray the leaves or water the bushes at the roots.
- Bordeaux mixture is considered the first fungicide to be used to protect agricultural plants. A mixture of copper sulfate and 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, Bordeaux mixture is successfully used as a prophylactic against pathogenic microflora. Cucumbers are treated with 1% Bordeaux mixture at the stage of 2-3 true leaves, followed by repeating the treatments after half a month.The last procedure during the fruiting period should be carried out no later than a week before harvesting.
- Hom is copper oxychloride, a fungicide that has become a substitute for Bordeaux mixture. In contrast, Hom is easy to prepare. The finished powder is diluted with plain water and used to spray plants. The drug does not adhere well to the surface and is easily washed off by rain. Cucumber is a greenhouse crop, so the fungicide is excellent for treating it in closed ground conditions. The natural question is whether cucumbers can be treated with the drug in open ground. Of course, only in dry, windless weather. Hom is a contact fungicide; it acts on the surface of the plant without penetrating its cellular structure and combines well with other pesticides. Plants are sprayed 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 harvesting.
- Sumilex is a chemical preparation with protective and healing contact action. Accumulating in 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 soil.
- Fundazol is used for treating seeds, as a preventive and therapeutic agent for the plants themselves. Fundazol demonstrates its therapeutic effect only in 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, the list of which includes the larvae of aphids, leaf beetles and spider mites. Fundazole is used in the form of a solution. They are used to treat seeds, water the roots, and spray the stems and leaf axils. The preparation and use of the drug must 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 healing and protective drug. Effectively stops mycelium growth and fungal spore formation. The plant is sprayed with the working solution every two weeks. The last time you can spray cucumbers is a month before harvest. The result of the treatment appears within a couple of hours. The drug, unlike other fungicides, can be used at low temperatures down to +1 degrees, on wet foliage and during flowering. The drug treats a number of cucumber diseases, including downy mildew.
- Topaz is a means of protection against a number of fungal diseases. Can be used as a preventive and therapeutic drug. Topaz has a high speed of action. After just 3 hours, the growth of mushroom mycelium stops. For 14-18 hours, Topaz continues to protect plants. 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 combines well in mixtures with other pesticides. Topaz is suitable for preventive and therapeutic treatments of cucumbers in unprotected soil, is well tolerated by plants, and is non-toxic to birds and insects.
- Quadris is a preventive and health-improving drug, a highly effective fungicide used for treating 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 ensure that the leaf surface is completely covered 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 on private farms.
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 needed. Spray the plants, then wash the container thoroughly. Follow safety precautions.
Important! Many drugs are very toxic, dangerous even to humans.
