Instructions for use of Topaz fungicide for plants, composition and analogues

The danger of fungal diseases lies in their rapid spread and sudden manifestation. Topaz is a chemical developed to treat and prevent the development of mold. Garden and vegetable crops, as well as indoor flowers, are treated with insecticide. Detailed instructions for using the Topaz fungicide will help you choose an effective dose of the drug for specific crops.

Description and properties of the drug

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

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

The product is used for the following diseases:

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

The main area of ​​application of the drug is the treatment of powdery mildew. When working with Topaz, you must strictly adhere to the dosage. Excess of the product harms the beds and crops.

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

Release form and composition

Avard, or penconazole, belongs to the chemical class of triazoles. The pesticide works better at the onset of the disease. It spreads throughout the plant faster than spores, and the mold does not have time to multiply.

"Topaz" is produced in the following packages:

• ampoules with a volume of 2 milliliters;
• plastic bottles with a capacity of 1 liter;
• 3 ml sachets.

Small volumes of the product are convenient to use in summer cottages, while large volumes 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, steroid derivatives.

Features of the fungicide:

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

The fungicide prevents re-infection. New spores do not develop, and the plants overcome the old plaque on their own.

Advantages and disadvantages

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

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

If you spray gooseberries and currants growing in the garden with “Topaz” for more than two years, a toxic dose of the active component will flow from the soil into the crops growing nearby.

In vineyards and 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 harvest is harvested 2 weeks after treatment with Topaz. If there is a drought after the last spraying, the waiting period increases to three to four weeks.

Preparation of working solution

How to prepare an aqueous solution of the drug “Topaz”:

• fill the mixture tank a quarter full;
• add the suspension in the required concentration;
• stir;
• bring the total volume to ten liters, continuing to stir.

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

Dosage and instructions for use

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

The table shows the approximate consumption of the solution:

The dosage varies depending on the type of plant, but the final volume of liquid 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, wait 14 days between sprayings, and 21 days in dry weather.

To disinfest apple trees, it is recommended to dissolve 3 milliliters of the product.

For grapes

A big problem in gardening is infection of the vineyard with oidium. The berries turn white and become 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 berry growers

For disinfestation of gooseberries and perennial berries, a minimum dose is also used. The product 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 product are used per bush.

For vegetable crops

“Topaz” in greenhouses and in the garden is often used for preventive purposes, before the fruits ripen. Vegetables are safe to eat 2 weeks after disinfestation. The dosage for seedlings in open ground is 1.5 milliliters, for a 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 a higher dose of the drug - 5 milliliters per standard 10 liters or 4 milliliters per 8 liters. The frequency of spraying is 3 with a break of 14 days. For preventive measures, Topaz is used during the budding period, and as a medicine - after the buds wither. Repeatedly flowering varieties are treated after each wave of flowering.

For strawberries

To treat fungus in strawberry beds, you need to use 2.5 milliliters of the drug. Liquid consumption is 0.5 liters per square meter. The first disinfestation is carried out before the flowers appear, and the second - after the fruits ripen and are harvested. Preventive spraying of strawberries is carried out from the 20th of May, early June.

For flowers in flower beds

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

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

Increasing the dosage is allowed only in flower beds in the garden, near which fruit bushes or vegetables do not grow. The flower garden is cultivated 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. Too much irrigation leaves permanent stains on the petals.

For indoor plants

“Topaz” can be used on home flowers that stand in the fresh air. It is better not to spray plants that are constantly in the room or take them out into the garden. You can bring them back 4 hours after treatment.

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

Hazard class and precautions when working with the product

The drug "Topaz" was assigned class 3 - moderate danger to humans. The chemical is deadly to bees, birds and fish.

• remove the soil and burn it in the oven;
• Collect from the skin with a cotton pad soaked in alcohol, then rinse your hands in water;
• Rinse eyes generously with water.

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

Compatibility with other tools

“Topaz” is included in complex preventive mixtures against fungi and pests.

Penconazole is added to the following drugs:

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

How to store the drug

Rules for storing Topaz fungicide:

• in a dark, dry place, away from heating devices 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 product 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?

The working solution cannot be stored. The interval between spraying 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?

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

A drug with a similar effect is prepared from improvised means - milk and salt diluted in water.The spores dry out in a salty environment, and the fungus does not reproduce.
