Best used in dry and calm weather. It is advisable to spray the plants at sunset so that the sun's rays do not burn the foliage. Optimally, if, according to the forecast, precipitation is not expected in the next 3-4 days
Release form and composition
The fungicidal preparation is produced by 2 companies - Avgust and Syngenta. This is a concentrated emulsion (e), packaged in ampoules of only 2 and 10 ml (Avgust) and in 1 liter bottles, 5 liter canisters (Syngenta).
The active substance of Topaz is penconazole, it is in the emulsion 100 g per 1 liter. It is quickly absorbed by the tissues of the treated plant, spreads to all its parts, thereby protecting not only foliage and stems, but also young shoots, even under adverse weather conditions.
Safety measures during processing
Use protective equipment when working with Topaz!
Despite the fact that the drug is not very dangerous for both humans and insects, as well as animals, the treatment should be carried out taking into account the safety rules:
- All strangers, children, and pets must be removed from the site.
- A mask, glasses and gloves must be worn. It is also advisable to wear a raincoat or disposable gown.
- No food, drink or smoking is allowed during spraying. Don't be distracted by conversations.
- If the drug gets on an open area of the skin, it must be washed immediately with water and soap.
- In case of contact with eyes, treat with water jet as soon as possible (under low pressure).
- If the solution accidentally gets inside, you need to take 5-7 tablets of activated carbon and wash them down with water.
If any other symptoms occur, stop working immediately and consult a doctor.
If there is an apiary nearby, bee years can be started after 3-4 days.
How to use it correctly?
The waiting time for Topaz to dissolve in water at room temperature is limited by the time of thorough mixing. Spraying the bushes is carried out in conjunction with the treatment of a soil area within the radius of the plant's root system, which is also a preventive measure against fungal spores that overwintered near the cultivated plant.
The first treatment is carried out before the buds open, the leaves appear. In the spring, the disease of the vine cannot be determined until the leaves have bloomed. Preventing fungal contamination of the seedling is always easier than treating the plant. The disease takes away the strength of the plant, which affects the taste of the grapes, the size of the harvest.
Attention! The processing of plants from 1 are of land takes from 1.5 to 2 liters of the dissolved agent, which depends on the height of the cultivated crops.
If the disease could not be prevented at an early stage, then the next treatment should be carried out 10 days after the first. Further, prophylactic antifungal sprays of all parts of the bush are carried out every decade, while the instructions indicate only 2 mandatory treatments - in spring (before the flowering of the bush) and in autumn (after harvesting, pruning the bush and falling foliage).
Despite the fact that the tool is not susceptible to loss of its properties during temperature extremes, a sharp cold snap, it makes no sense to use it for winter treatment of bushes.
For dormant mycelium, "Topaz" is safe, because the growth of fungal spores will begin only when warm days come, and the period of action of the antifungal agent will end in 2 weeks. The recommended number of spraying of fruit trees per season is no more than 4 times. When a plant is damaged, in order to save it, a larger number of treatments are allowed.
Analogues of "Topaz"
Analogues of "Topaz" include 2 fungicides that have the same active ingredient in the composition (penconazole, 100 g / l):
- "Diamond".
- Avarta.
"Almaz" is produced by Hungarian. This drug is used primarily to protect apple and grapes from the same fungal diseases. Fungicide "Avarta" is used in a similar way, although in Russia it is not so widespread.
Description
Grapes, being a delicate fruit crop, require special attention and quality care. Often, grape bushes infect various fungal diseases, as a result of which the fruits become smaller, lose their presentation and taste, yield decreases, the plant stops growing and developing. If you do not take emergency measures during the period of infection, then you can lose the entire garden.
Many gardeners prefer the traditional methods of fighting fungal infections that have been proven over the years. However, it is not always possible to get rid of one or another ailment that has struck the grape bushes with the help of ordinary folk remedies. More effective, as noted by experts in the field of viticulture, are fungicidal preparations. Today, specialized stores offer a wide range of fungicides. How to choose the best drug, you ask. Among the huge amount of fungicides, the drug "Topaz" is in great demand among modern gardeners, which has shown good results in the fight against many fungal diseases (powdery mildew, rust, fruit rot, etc.). The main active ingredient is penconazole, which belongs to chemicals of the third level of danger to humans and animals.
When treating a vineyard with this drug, you do not have to worry that the plants will stop growing and stop developing, as often happens when in contact with stronger chemists. The peculiarity of the Topaz fungicide is that under the influence of penconazole the spread of the fungus is suppressed and the protective function of plants is developed. This drug has a powerful effect on the causative agents of fungal diseases. Suitable for spraying vineyards even in rainy and windy weather.
Compatibility with other products
Topaz can be used with almost any other drug. Usually, for prophylaxis, treatment with only this remedy is enough.
For a complex effect (especially when the first signs of infection appear), it can be used together with other fungicides:
"Horus" - Helps to cope with coccomycosis, alternaria and clotterosporia.
"Topsin-M" - For the treatment of gray rot, scab, anthracosis.
"Cuprosat" - Treats late blight and cerosporosis.
These preparations contain other active ingredients, due to which they combine well with Topaz.
Systemic fungicides for the treatment of grapes
The mechanism of action of systemic fungicides is the penetration of the active substance into the affected culture, spreading through the juice and affecting the fungus "from the inside". This is a stronger drug. It is used for already infected grape plants.
Systemic fungicides are capable of destroying the mycelium, suppressing its reproduction. Before starting an active action,
the fungicide must be absorbed into the plant. This takes 2 to 6 hours.
From the moment of spraying, the grapes act for 21 days. The active ingredient spreads evenly over all stems, reaching the roots. 6 hours after treatment, any bad weather (rain, increased humidity, high temperature) is not dangerous.

The only significant drawback
—
the ability of the fungus to adapt over time to such funds.
Systemic fungicides for grapes: Quadris, Strobi, Skor, Topaz, Falcon, Folpan.
Advantages and disadvantages
Fungicide "Topaz" has shown its high efficiency both when used in private households, and in the case of application on an industrial scale (including in aerial processing).
This is a systemic drug that quickly destroys diseases and provides reliable prevention of the development of fungal infections.
Its main advantages include the following:
- Can be used at any stage of growth - both at the beginning and at the end of the season.
- Protects various crops - berries, shrubs, fruit trees, flowers, cucumbers.
- Due to the long-term exposure, in most cases 2 treatments are sufficient with an interval of 2 weeks.
- Since the active substance enters the plant tissue very quickly, the risk of being washed away by rain is reduced.
- The drug does not leave a trace on the fruit, which is what many other fungicides and pesticides in general suffer from.
- The active ingredient is absolutely safe for plants (not phytotoxic).
- The fungicide is of little danger to both humans and beneficial insects.
- Processing is easy in any conditions.
- The consumption of funds is small - only 1-2 ampoules per bucket, which is enough for 1 hundred square meters or 1 bush.
- The cost is also small - 30 rubles for 1 ampoule. For a standard garden for 1 season, you can purchase 20-30 ampoules, which will cost no more than 1000 rubles.
However, this drug also has some disadvantages:
- It is only safe at the indicated dosage. If exceeded, it can lead to the death of the plant.
- The agent can accumulate in the soil, so you should not treat plants in the same area for 3 or more years in a row.
- It is a one-component solution that has no additional effect (eg growth stimulant, fertilizer). However, almost all other fungicides have a similar disadvantage, so it can be attributed to the disadvantages only conditionally.
Mechanism of action
Penconazole inhibits fungal spores, stopping the reproduction and spread of diseases. The effect of Topaz is possible even at a temperature of 10 ° C, it can be used even when it is raining lightly (due to its rapid absorption into plant tissues). The drug begins to act within 0.5 hours after treatment, stops the growth of the fungus in 2-3 hours. The time of the protective effect of Topaz is 1.5-2 weeks.
The timing of treatment with this fungicide is at the beginning of the season for preventive purposes (to suppress a possible primary infection and prevent spread to healthy plants) and when the initial signs of the disease are detected.
Should I use Topaz fungicide: gardeners reviews
Do you consider Topaz fungicide an effective remedy?
Of course! Not really
According to various Internet portals, "Topaz" is actively used by many gardeners, and the tool regularly receives high ratings from users (4.4-4.5 points out of 5).
A year ago, she began to actively grow violets, they grew quickly and confidently, pleasing to the eye. But in the middle of summer, some kind of dust appeared on the leaves. At first, I didn't think about the fungus at all, but it turned out to be powdery mildew, as they later suggested on the forum. I bought the first available product. Fortunately for me, it turned out to be Topaz. This is an excellent drug that costs a penny, but it helps for the entire season. I carried out one treatment and the second after a couple of weeks - the dust disappeared completely. And even this season I didn't hit the plant anymore - I haven't processed it yet, but I have already prepared several ampoules.

When our currants were covered with powdery mildew, a neighbor came and said to dig it up and burn it. I nevertheless decided to try to process it with something. I read several reviews and bought Topaz: it is inexpensive, at 28 rubles per ampoule. I processed it a couple of times in the month of July, used up a bucket per bush, generously not sparing it. The effect did not come immediately, but only after 2 years. Of course, during this time, many would have thrown out the currants, but it's not so easy to plant new bushes. So I definitely recommend it, especially for such a penny!

Topaz is quite a decent remedy, our domestic fungicide. I use it only for prophylaxis, purely according to the instructions. The neighbors periodically have rust on the cucumbers, but I did not have this at all. That's all I can say.

I decided to take a chance and grow a capricious rose Avolanche - whoever came across such a thing will understand. I did everything right, and suddenly - dust on the leaves means powdery mildew. I used to fight with folk methods, but a friend advised Topaz. I processed it like this: 1 ampoule for 5 liters of water, 2 times with an interval of 10 days. Gradually, the rose began to recover - it is true, the old branches bent, but new shoots started. I'm waiting for the result

51 years old, Korolev
I attacked the Topaz fungicide by accident. Just 5 years ago, rust settled on the gooseberry, and urgent measures had to be taken, folk remedies no longer helped. Topaz somehow immediately came to my liking, it helped very well in its time. And we also tried other means, but for some reason they do not give an effect. Perhaps the plants are already accustomed to a certain regime, so I am not planning to change anything yet.
