Fungicides for plants: what is it, a list of drugs
Every year, gardeners and gardeners begin the struggle for the crop. Flower lovers also constantly suffer when a favorite flowerbed dies due to the ubiquitous fungus. After all, no vigilance can save him completely, so fungicides are needed. What it is? Specialized antifungal drugs. Now we will tell you more about them and share a list of effective tools!
The composition of fungicides
Different fungicides are very different in composition. Chemicals are concentrated and effective, but require careful handling because they are toxic. They can be in the form of liquids, in powders or granules.
Organic are made on the basis of beneficial living bacteria that inhibit the functioning of fungi. This is a more environmentally friendly and safe option, so they can be used even indoors. But often they are ineffective in case of serious lesions.
Principle of operation
Fungicides affect the fungus at the cellular level and disrupt the natural processes of pathogens. Because of this, their distribution ceases, and they perish. For example, drugs can destroy protein and nucleic acids - the most important components of fungal spore cells.
Substances penetrate the very structure of tissues and spread throughout the body from the roots to the ends of the leaves. They effectively destroy even hidden spores that are not yet visible to the naked eye. Usually, treatment with systemic fungicides is carried out as a preventive, according to a schedule.
Emergency substances are needed in the treatment of diseases that have already manifested. They are applied directly to the affected areas, and there they immediately begin to work. The main thing is to keep the substance on the plant for at least several hours, so in case of unexpected rain, the treatment will have to be repeated.
The drugs are sold in different forms, and accordingly they can be used in different ways. Always read the instructions, because the same fungicides can usually not be used for spraying and for spreading to the ground. Even if possible, different concentrations are needed.
Before planting, it is necessary to treat the seed with an antifungal agent, if this is not a pre-processed store bundle. This is well known to all flower growers who each year bring forth new seedlings. Similarly, all bulbs and tubers must be pickled.
Some fungicides can be applied to the soil as fertilizers. Most often these are powders or granules that need to be evenly distributed during digging. Or you can prepare a solution for irrigation to destroy all spores in the soil.
The easiest and most popular way to treat plants is spraying. Irrigation and applications are less commonly used, but systematic and regularity is important in any case. Biological preparations can be used for home pots.
What plants can be processed?
Modern fungicides are suitable for any crops - you just need to choose the right product. There are preparations for tubers and vegetables, berries, trees or flower seedlings. Be sure to consider the conditions of use: season, temperature, plant condition.
Preventive treatments begin with the first warm days, even before the period of active vegetation. This is a measure that prevents the development of the fungus due to excessive humidity or low temperature. In autumn, it is a disinfection of the site before winter, so that the spores do not multiply in the ground.
Preventive spraying increases the immunity of pets and resistance to external influences. Timely treatment stops the spread of fungus, which is transmitted warmly between flowerpots especially quickly. Always process new acquisitions and seedlings so that they do not infect other plants.
Popular fungicides - list
We have studied dozens of popular fungicides and the specifics of their application, so that it is easier for you to choose. All of them are easy to prepare and universal in use.
This is one of the most popular mixes for seasonal spraying among gardeners and gardeners. The Bordeaux mixture forms a protective layer against fungus and bacteria, increases immunity and nourishes calcium with copper.
Another massive contact agent enhances fetal immunity. Copper sulfate is one of the active components of the Bordeaux mixture. So the effect is more precise, but concentrated.
One of the very popular chemical fungicides is great for young plants. As prevention of rot, spraying is carried out directly a couple of weeks before the harvest. Horus has a unique system of action on pathogens and high efficiency at low temperatures - from +3 degrees.
It is a completely organic and safe fungicide for apple trees, berries and potatoes. It is very good for protecting the seeds before the sowing season. Agate-25 is a safe preparation for ornamental and cereal plants.
Gardeners use it to protect primarily from powdery mildew and its consequences. This is a unique fungicide that works well at high humidity and low temperature.
Thanos copes best with late blight, against which other drugs do not help. The composition contains wax, which forms a protective film. It almost instantly has a local effect even in bad weather.
The chemical composition is notable for its quick action in combination with low toxicity. It is one of the safest and non-toxic fungicides for all types and forms of crops.
Another fungicide combines the advantage of both systemic and contact. The composition contains two active substances at once, so it is quickly absorbed and forms a protective film in parallel.
This fungicide is notable for its good antibacterial effect, for which it is appreciated. He copes with various diseases, including fusarium, late blight and all kinds of spotty lesions.
The organic mixture immediately improves the condition and quality of the soil. The fungicide inhibits the scab, prevents rot, prevents the appearance of rust and septoria. Irrigation Alirin-B has a good effect on the taste of the fruit.
A universal systemic fungicide consists of four components, therefore, it effectively copes with most types of mycoses. The effect will persist for a month and a half, depending on the amount of rain in the season.
Penetrating composition is good for prevention, but even better - for quick local treatment. The main disadvantage of the fungicide is its high toxicity, so be extremely careful about the dosage.
Topaz is far less toxic, so it can be safely used for home seedlings. But Topaz can be applied to the soil only once every couple of years, because it accumulates in the soil.
One of the newest broad-spectrum fungicides has a long-lasting protective effect. The composition contains several active ingredients, so the drug fights most of the common lesions.
The fungicide Ordan contains several active components and copper oxychloride at once. It inhibits the development and spread of parasites after two treatments.
Universal fungicide protects against diseases and strengthens the immune system. Cultures adapt better to new conditions and do not react so strongly to stress. Albite can be used to neutralize the effect of an overdose of pesticides.
The new tool is very effective in adverse weather conditions. Fungicide fights well with fungi, spotting, rot and rust. The bottom line is that the active substances instantly penetrate the structure of the plant, so rain does not wash it.
Lovers of flowers and ornamental crops use the fungicide Mikosan for gentle processing. It has a completely different principle of action, because it does not kill bacteria and fungus directly, but helps the plant cope with it on its own.
Contact fungicide is good for pre-sowing treatment of seed and soil. Less commonly, it is used in spraying to avoid the appearance and spread of fusarium. Maxim is one of the best tools for the safe destruction of mold.
Another universal bacterial agent protects the root system of plants. The fungicide Planriz has a special mechanism of work: beneficial microorganisms settle in the rhizome and produce protective enzymes.
Vitaros fungicide is used in the preparation of material for sowing, including tubers and bulbs. This is a two-component drug that inhibits fungal cells and bacteria. A liter of liquid is enough per kilogram of seeds.
Contact fungicide works against most fungal diseases. It effectively inhibits pathogenic organisms and, in the long term, reserves a prolonged effect.
Chemical fungicide is best suited for processing vegetable beds, and also for vineyards. It is quite toxic, like many other garden preparations, but it has a long working life.
The tool is particularly well-proven for flowers: these are indoor, garden and greenhouse species. Phytosporin is completely environmentally friendly. Gardeners love it because they can process the beds on the day of harvest.
Strobi fungicide is not only notable for its good antifungal, but also antibacterial properties. It is suitable for all types of crops and vineyards. The development and spread of the fungus stops instantly.
How to cook fungicide?
Almost all fungicides are prepared according to the same principle and differ only in dosages. It is better to mix the product immediately in the sprayer, so as not to stain household containers with chemicals. Fill the tank one third, add the right amount of fungicide, mix thoroughly, add the rest of the water and mix again.
Solutions are prepared immediately before use because they retain their effectiveness for only a couple of hours. Be sure to use protective equipment: work clothing, gloves, a mask, a respirator. Use fungicides on a sunny warm day so that there is no strong wind or rain.
