Horus and Skor are popular products that protect various fruit trees from fungal diseases. Many gardeners confuse them or consider them interchangeable. Details about the composition of these products, their active ingredients, their similarities and differences, and the nuances of their use will help gardeners make the right choice.
Comparative characteristics
Both products are systemic fungicides with therapeutic properties. They can be used prophylactically and provide long-term protection against various types of fungal infections. Skor is available as a concentrated emulsion, while Horus is available as water-soluble granules.
Skor and Horus contain different active ingredients. Skor belongs to the triazole class and contains difenoconazole at a concentration of 250 grams per liter. Horus contains cyprodinil at a concentration of 750 grams per kilogram.
These products are used to treat fruit trees (apple, pear, quince, cherry, plum, and sweet cherry). They also protect grapes, gooseberry bushes, and black and red currant bushes from fungal infections.
The preparations have a similar effect on plants; when sprayed, they quickly destroy:
- various types of fruit rot;
- scab;
- coccomycosis;
- Alternaria;
- powdery mildew;
- Clusterosporiosis.
"Skor" is more active against powdery mildew than "Horus." It is used for treatment and preventative treatment against leaf spot and scab, improving the growth of treated trees and shrubs and the buildup of green mass. It can also be used as a seed dressing. After treatment, seedlings emerge more uniformly, resist disease, and develop better.
"Skor" effectively protects plants during warm periods and high humidity—when fungal infections spread most rapidly. "Horus" offers better protection against monilial blight, combats scab, and is effective in the early stages of fungal diseases. It is used before flowering, during the green cone stage, as an effective preventative measure.
Bottom line: what is better to buy?
Both products are effective and provide excellent plant protection. When choosing, keep in mind that "Horus" is effective at temperatures starting from +5°C, while "Skor" is effective at temperatures starting from +12°C.
To prevent the fungal infection from developing resistance to the drug used after treatment, it is better to use them alternately.
Important: Do not mix the products. In the early stages of growth, it's more effective to treat fruit trees and shrubs with Horus, followed by Skor. This will ensure complete protection against infection.
Use the products according to the manufacturer's instructions; exceeding the dosage will harm the plants. Spray the plants in dry, windless weather. The products penetrate the plant system, and subsequent precipitation does not reduce their effectiveness. They are suitable for tank mixing with insecticides, fertilizers, and pesticides.
The use of Horus and Skor products in your garden plot allows you to effectively protect plants during the growing season from the most common and dangerous types of fungal infections.
