In gardening, one cannot do without the use of chemicals, since with the arrival of spring, phytopathogenic fungi begin to parasitize young leaves and shoots. Gradually, the disease covers the entire plant and causes significant damage to the crop. Among the variety of drugs, many gardeners choose Delan fungicide. It has a comprehensive effect on fungal diseases and is suitable for both grapes and some fruit trees.

Let's get acquainted with the description, instructions, advantages and disadvantages of the Delan fungicide. Let's find out how to use it correctly and in what dosages.

Characteristics

Fungicide Delan is a contact preparation that effectively affects fungal spores, regardless of the stage of their development. The substance is not intended for application into the soil or for soaking seeds. The product is sprayed onto the leaves and stems of cultivated plants and is characterized by resistance to low temperatures and precipitation.

Summer residents use Delan fungicide to prevent and treat fungal infections. It is effective for various diseases:

scab;
Clusterosporiasis (hole spotting);
late blight (brown rot);
leaf curl;
mildew (downy mildew);
rust;
moniliosis (fruit rot).

The fungicide is available in the form of granules that easily dissolve in water. For large-scale farms, you can purchase a bag weighing 5 kg; for small summer cottages, a bag weighing 5 g is enough.

Important! Fungicide Delan should not be used together with preparations that contain oily substances.

Mechanism of action

The drug contains the active ingredient dithianon, the concentration of which is 70%. The active substance acts on the virus by contact, enveloping the leaves and stems with a dense layer that is not washed off by rain. The compound is resistant to water, but is destroyed by acids and alkalis. The fungicide is evenly distributed over the surface of the plant tissue and provides long-term protection to the plant.

Dithianon inhibits the growth and spread of fungal spores, which die under its influence. The remaining part of the plant is not affected by the virus.

The active substance has a versatile effect on the fungus, so the likelihood of pathogens becoming accustomed to Dithianon is minimal.

Advantages

Attention! For greater effectiveness, it is better to apply the Delan fungicide before the first signs of the disease appear. For prevention, it is recommended to spray the plant every spring.

Flaws

The fungicide has no serious disadvantages. Despite the wide range of effects against fungal diseases, the product cannot be used for all crops. The drug Delan is suitable only for grapes and fruit trees. It also does not provide protection to plants from the inside.

Preparation of the solution

The Delan fungicide solution is prepared immediately before treatment, since it cannot be stored. To prepare the working fluid, 14 g of granules need to be poured into a bucket of water with a volume of 8-10 liters and dissolved. According to the instructions for use, spraying is carried out at intervals of 15-20 days. If the weather is rainy, then the interval is reduced to 9-10 days. The total number of treatments is from 3 to 6 depending on the type of crop.

One average tree will need 2 to 3 liters of solution. The above-ground part of the plant is evenly sprayed with a fungicide solution from all sides. For convenience, use a spray bottle and fine-droplet mode.

Apple tree

Many gardeners observe such an unpleasant phenomenon as scab on apple tree. The disease is manifested by the appearance of yellow and dark spots on leaves and fruits. The greenery dries up and falls off. This parasitic fungus can significantly reduce the yield and cause harm to it.

Fungicide Delan will help cope with the disease in a short time. Prepare a standard solution according to the instructions and treat the fruit tree 5 times with an interval of 8-11 days. The first spraying is carried out during the leaf blooming period. 100 ml of working solution or 0.05-0.07 g of dry matter is consumed per square meter of planting.

Peach

The most common fungal diseases of peach are scab, cluster blight and leaf curl. Fruits, bark and greens are affected. To preserve the harvest and protect the fruit tree, you need to carry out timely prevention with Delan fungicide, following the instructions.

The first spraying is carried out during the growing season. At 1 m² 100-110 ml of working solution or 0.1 g of dry matter is consumed.

Attention! Fruits can be collected no earlier than 20 days after the last treatment with the drug.

Grape

One of the most dangerous fungal diseases of grapes is mildew. First, light spots with a white coating on the reverse side form on the foliage, then the shoots dry out, and the ovaries rot and fall off.

In order not to lose the harvest and berry bushes, the grapevine should be treated with Delan fungicide. The plant is sprayed 6 times throughout the entire season, with each subsequent procedure performed after 8-11 days. According to the attached instructions for 1 m²area, 0.05-0.07 grams of fungicide or 90-100 ml of working fluid are consumed. The protective effect lasts up to 28 days.

Reviews from summer residents

Mikhail, 31 years old, Krasnodar city

This year we had a rainy and wet spring. Typically, diseases become more active in such weather, and fruit trees suffer. I have a peach growing in my garden, its leaves have begun to curl, turn yellow and dry out. Usually the Delan fungicide always helped me out. I dilute the drug according to the instructions and treat the tree during the growing season. I'm very glad that it doesn't wash off in the rain. After spraying, the peach came to life and new, healthy leaves appeared. The product fights Mildew well and ensures healthy growth, even in such cloudy weather. I also use it for grapes.

Svetlana, 53 years old, Saratov

Every spring I spread Delan fungicide and carry out preventive treatment of trees and shrubs in my garden. I choose it because it is effective even at low temperatures and frequent precipitation. Apple Tree and Peach Tree have not been sick for several years. Sometimes I alternate it with other drugs. But this is still a chemical, so you need to use it carefully and not exceed the dosage specified in the instructions.

Conclusion

Fungicide Delan is a very effective, modern and antifungal product that is suitable for treating fruit trees and grapevines. It suppresses the development of many parasitic fungi on the surface of the plant. If the disease continues to develop after spraying, contact a specialist.
