Fungicide Quadris: description, instructions for use
Powdery mildew, all kinds of spotting, silver scab, late blight, peronosporosis and other types of fungal diseases mercilessly destroy the planting of cultivated plants. This problem was especially acute for farmers and summer residents in connection with weather anomalies that have been observed in recent years. But the problem has a solution - the fungicide Quadris. We tell in more detail!
Fungicide Kvadris - a unique drug that was developed specifically to combat a number of fungal diseases of vegetable crops, grapes and sports lawns. The active substance is azoxystrobin, the effectiveness of which is many times greater than the effect of other chemicals on the market today.
Quadrice destroys not only the mushrooms themselves, but also their spores. But at the same time, this substance does not harm the environment and processed plants in any way, and their fruits become safe for humans 5-7 days after the use of the drug.
Quadris is widely used as a preventive, curative and eradicating action against diseases caused by fungi of the four most common species - Oomycetes, Basidiomycetes, Ascomycetes, Deuteromycetes. When used correctly in accordance with the instructions, spores of these fungal pathogens can be completely eradicated in the area, providing long-term and stable protection for future plantings.
In addition to the therapeutic effect, the use of this drug activates photosynthesis in the leaves, increases the level of moisture absorption by plants, which helps to significantly increase productivity, improve the quality of fruits. After using the fungicide Quadris, vegetables and grapes are stored for much longer, because they do not lend themselves to rot.
The principle of the drug
Quadris is most effective during the early stages of the development of fungal and some bacterial plant diseases. If the situation is severely neglected, then this fungicide should be used together with Ridomil Gold, Topaz, Skor and others.
The active ingredient of Quadrice destroys the genome of fungi and pathogenic bacteria, which guarantees a positive effect for farmers. Fungicide is able to penetrate not only into the leaves and stems of plants, thereby providing a therapeutic effect. It is also used to disinfect planting material, destroying pathogens inside the seeds.
Due to the fact that Quadris is a relatively safe drug, experts recommend it to be used in preventive measures. To do this, young plantings of tomatoes, onions, cabbage, cucumbers, hops, potatoes, as well as vineyards and lawns are treated with a fungicide solution, without waiting for the first signs of damage to the plants.
Recommendations for the use of Quadris
Kvadris systemic fungicide is sold in the form of a concentrated suspension, which must be dissolved in water. The consumption of the drug is very economical. Working solution: maximum 0.1% for grapes or 0.2% for vegetables.
The sprayer reservoir should first be filled to a quarter volume with water, then add the required amount of Quadris and mix thoroughly. Only then add the remaining water and mix again. The solution remains effective during the day.
The resulting liquid must be treated planting. To do this, use a spray gun or other special equipment for ground spraying of vegetables, shrubs and trees. In order to achieve maximum effect, the manufacturer recommends performing two to three treatments in one season.
Dosage and consumption
To process plantings of vegetable crops, you need to prepare a 0.1 percent fungicide solution. To do this, dilute 1 g of pure water with 1 g of the drug.
For the treatment of hops, tomatoes and cucumbers from various types of fungal lesions, 2 treatments will be required. For potatoes, onions and peas - 3, and for cabbage it is enough to spray the ground parts of plants 1 time. One week after the last application of the Quadris fungicide solution, you can start harvesting.
To treat vineyards from gray rot, infectious drying, mildew, oidium and black spotting, you need to dissolve 2 g of Quadrice in 1 liter of water. The number of treatments is 3, with the latter being carried out no later than 25 days before harvesting.
The active substance of the drug can settle to the bottom of the tank in which it is located. To avoid getting too concentrated liquid on the plants or, conversely, not sufficiently active, it is necessary to mix or shake the solution in the tank from time to time.
Processing of plants is carried out by the smallest spray, since Quadris is effective in the fight against fungi and bacteria that affect plantings, in minimal doses. For this reason, there is no need to water the leaves and stems too abundantly with a solution of this fungicide.
It is important to emphasize that Quadris cannot be used in the same area at the same time as herbicides. In addition, the drug can be phytotoxic (it reduces resistance to sunlight, which leads to burns) for some varieties of apple trees, so if you use one sprayer for the garden, vineyard and vegetable plantings, then the tank and all details should be very thoroughly washed.
Prepare a solution of fungicide in small volumes, this will allow you to spend the drug economically and without residue. If a little solution still remains, pour it in a remote place, where there are no nearby sources of water. Then pour more water into the sprayer tank, rinse thoroughly and pour in the same place. Repeat the procedure a few more times.
