Fungicide Topaz: instructions for use for plants, composition and analogues

The danger of fungal diseases is in their rapid spread and sudden manifestation. "Topaz" is a chemical preparation designed to treat and prevent the development of mold. Insecticide is treated with garden, garden crops, as well as indoor flowers. Detailed instructions for the use of the Topaz fungicide will help you choose the effective dose of the drug for specific crops.

Description and properties of the drug

Insecticide "Topaz" has a systemic effect. It is used on the following groups of plants:

• berry bushes;
• fruit trees;
• flower beds, ampelous flowers;
• vegetables;
• vines.

The remedy is used when the following diseases appear:

• brown spotting;
• rust;
• gray rot;
• oidium.

The main scope of the drug is the treatment of powdery mildew. Working with "Topaz", you must strictly observe the dosage. Excess funds harm the beds and crops.

The active substance is called penconazole and stops the development of spores. Deprived of the ability to reproduce, the fungus dies. The pesticide is used in rainy and hot weather, and even during night frosts.

Prevention with the help of "Topaz" is carried out in the spring, and treatment - throughout the entire period of plant development. The fungicide is combined with pesticides.But it cannot be used for more than three years. Fungi become insensitive to the pesticide with prolonged spraying. To avoid addiction, the agent is alternated with fungicides based on another substance.

Form and composition

Award, or penconazole, belongs to the chemical class of triazoles. The pesticide works best early in the disease. It spreads throughout the plant faster than spores, and the mold does not have time to multiply.

Topaz is available in the following packages:

• 2 ml ampoules;
• 1 liter plastic bottles;
• sachets of 3 milliliters.

Small volumes of funds are convenient to use in suburban areas, and large ones are designed for hectares of farms and vineyards. Penconazole in its pure form is water-insoluble crystals. Therefore, it is converted into a suspension that can be added to water.

Mechanism of action

Penconazole disrupts the synthesis of substances in spore cells. The substance blocks the production of mycosterols - derivatives of steroids.

Features of the fungicide:

• does not settle on the leaves with a film;
• transported to the roots and inflorescences along with the juice;
• The highest concentration of penconazole occurs after the fourth spray.

Fungicide prevents re-infection. New spores do not develop, and the old plaque of the plant wins on its own.

Pros and cons

The main advantage of "Topaz" is the relative safety for the crop. Fruits and vegetables can be harvested on time, which is convenient for owners of private plots. On farms, the pesticide content is checked using laboratory tests.It is not profitable for summer residents to order research for a small crop.

Pros and conseconomical consumption;three forms of release;long shelf life;fast absorption by plants;action half an hour after spraying;high efficiency between sprays, regardless of the environment;universality;compatibility and preservation of properties in combination with other insecticides and fertilizers.accumulates in the ground;does not destroy downy mildew;the main component slowly decomposes in hot weather.

To prepare an effective solution, a small proportion of the suspension is required. To use the drug for its intended purpose, you need to be able to distinguish mildew from real powdery mildew, otherwise the vineyard will die even after treatment with a fungicide. Penconazole in a weak solution disintegrates in a season. But in small areas, the rate of decay of the substance decreases.

If you spray "Topaz" gooseberries, currants growing in the garden for more than two years, a toxic dose of the active ingredient will get from the soil into crops growing nearby.

In vineyards, apple orchards, a constant concentration of the drug, on the contrary, helps prevent the sudden spread of powdery mildew. Therefore, in specialized areas, the fungicide can be used for up to four years in a row. In the normal or rainy season, the crop is harvested 2 weeks after Topaz treatment. If drought has occurred since the last spray, the waiting period is extended to three to four weeks.

Preparation of working solution

How to prepare an aqueous solution of Topaz:

• fill the mix tank a quarter;
• add suspension at required concentration;
• stir;
• bring the total volume to ten liters while continuing to stir.

Insecticide is dissolved before spraying. The drug is sprayed evenly, in one layer. Favorable time of day and conditions for disinsection of the site are morning and evening twilight, with calm, clear weather.

Dosage and instructions for use

The initial amount of fungicide is 2 milliliters per 10 liters of water.

The table shows the approximate consumption of the solution:

Blackcurrant 2 Gooseberry 2Strawberry 5Raspberries 1,5-2 Grapes

Plant	Consumption of solution in liters per 100 square meters

The dosage varies depending on the type of plant, but the final liquid volume is almost always ten liters.

For fruit trees

In orchards, 2-4 treatments are carried out during the growing season. For prevention, trees are sprayed at the beginning of bud swelling and after flowering. When treating plantings in wet weather, they stand between sprayings for 14 days, in dry weather - 21 days.

For disinsection of an apple tree, it is recommended to dissolve 3 milliliters of the product.

For grapes

A big problem in horticulture is the infection of the vineyard with oidium. The berries turn white, covered with a floury coating. The vines shed their leaves faster and wither. For spraying, the initial dose of Topaz is diluted. When symptoms of mold appear, the vineyard is treated 4 times, for prevention - once before and after the formation of flowers.

For berries

For the pest control of gooseberries and perennial berries, the minimum dose is also used. The agent is sprayed at the beginning of flowering and before fruit set. The total number of sprays is four. When treating currants, 1-2 liters of the product are spent per bush.

For vegetable crops

"Topaz" in greenhouses and in the garden is often used for preventive purposes, before the fruit ripens. Vegetables are safe to eat 2 weeks after pest control. The dosage for seedlings in the open field is 1.5 milliliters, for the greenhouse - 2 milliliters. Fertilizer is applied according to the usual scheme, four times per season.

For roses

Standard varieties are sprayed with a solution with an increased dose of the drug - 5 milliliters per standard 10 liters or 4 milliliters per 8 liters. Multiplicity of sprays - 3 with a break of 14 days. For preventive measures, "Topaz" is used during the period of budding, and as a medicine - after the buds wither. Multi-flowering varieties are treated after each flowering wave.

For strawberries

For the treatment of fungus on strawberry beds, you must use 2.5 milliliters of the drug. Liquid consumption - 0.5 liters per square meter.The first disinsection is carried out before the appearance of flowers, and the second - after ripening and collecting fruits. Preventive spraying of strawberries is carried out from the 20th of May, early June.

For flower beds

Concentration of "Topaz" in the treatment of mold on ornamental plants:

• 2 milliliters - against powdery mildew;
• 4 milliliters - against rust.

It is allowed to increase the dosage only in flower beds in the garden, near which fruit bushes or vegetables do not grow. The flower garden is processed in the evenings. For herbaceous plants and low shrubs, 1.5 liters per square meter is sufficient. When spraying petunias, it is advisable to avoid getting the solution on the flowers. From too abundant irrigation, indelible stains remain on the petals.

For indoor plants

"Topaz" can be used on indoor flowers that stand outdoors. Plants that are constantly in the room should not be sprayed or taken out into the garden. You can bring them back 4 hours after processing.

To combat mold on indoor plants, one milliliter per 10 liters for lush and half a milliliter for small species is enough. The drug is sprayed in a small amount every 2 weeks until the signs of the disease disappear.

Hazard class and handling precautions

Topaz has been assigned the 3rd class - a moderate danger to humans. The chemical is deadly to bees, birds and fish.

Permissible distances from the processing area:

• to reservoirs, playgrounds, park areas - from 150 meters;
• to pedestrian streets, poultry houses and barns with livestock - 50 meters;
• to residential buildings - 15 meters;
• to the apiary - 2.5 kilometers.

Bees must not be released over sprayed plants for 72 hours.

It is safe to work with the drug for six hours in personal protective equipment:

• waterproof shoes, raincoat or apron;
• in a headdress;
• safety glasses;
• Petal type respirator.

How to clean up a spilled clean slurry:

• clean hard surface with organic solvent;
• remove the soil and burn it in the oven;
• collect from the skin with a cotton pad dipped in alcohol, then rinse hands in water;
• Rinse eyes with plenty of water.

After ingestion, you need to drink a pink solution of manganese. Potassium permanganate neutralizes the action of penconazole.

Compatibility with other products

"Topaz" is included in complex preventive mixtures against fungus and pests.

Penconazole is added to the following drugs:

• "Ridomil Gold" - for the treatment of grapes;
• "Kuprostat" - against late blight, cercosporosis;
• "Thiovit Jet" - for the destruction of ticks;
• "Aktara" - against insects;
• "Zircon" - to accelerate growth.

Penconazole does not react with the active ingredients of the drugs, so there is no need to reduce their concentration.

How to store the drug

Topaz fungicide storage rules:

• in a dark, dry place away from heaters and direct sunlight;
• at temperatures from -10 to +35 degrees.

The shelf life of the drug in sealed original packaging is 4 years. It is advisable to use the tool in the first half of the term. The active substance becomes more aggressive closer to the end date of use.

Can it be stored diluted

Working solution cannot be stored. The interval between sprayings is 10-14 days. During this time, penconazole will disintegrate in water, and the mixture will lose its protective properties. Therefore, before each spraying, a new portion of the drug is prepared.

What analogues are there?

"Topaz" can be replaced by the following drugs with the same active ingredient:

• "Diamond";
• "Thiophene Extra";
• Jack Pot.

A drug of similar action is prepared from improvised means - milk and s alt, diluted in water. The spores dry out in the s alty environment and the fungus does not reproduce.
