Skor and Horus: comparison of drugs and instructions for their use

Fungicidal treatment of crops and fruit trees is the most important stage of sustainable farming. Fungal colonies multiply rapidly, adversely affect the development of plants and cause crop loss. The popular tool "Skor" and the drug "Horus" are widely used in agriculture and household plots. The effectiveness of fungicides puts farmers before a choice, but preparations have their own characteristics and conditions of use.

Comparison of Chorus and Skor preparations

Fungicides "Skor" and "Horus" have a therapeutic effect of a systemic nature, protect plantings from fungal infections, creating a resistant protective barrier.The composition of the preparations includes substances from different chemical groups, which causes differences in the mechanism of action on fungal agents.

Means have a similar use, showing activity against the causative agents of the following diseases:

• powdery mildew;
• scab;
• alternariosis;
• fruit rot;
• clasterosporiasis;
• coccomycosis.

"Horus" has a weaker effect on the powdery mildew pathogen, but is effective in the fight against scab, moniliosis and monilial burn. It has a good effect in the early stages of infection.

"Skor" has targeted activity against powdery mildew, scab, spotting and pronounced preventive properties. The drug stimulates the growth of foliage and shoots, accelerating the growth of green mass. The tool is also used for preplant seed treatment.

Both formulations are designed for spraying on the following trees and shrubs:

• apple tree;
• pear;
• cherry, cherry;
• plum, cherry plum;
• peach, apricot;
• grapes;
• currant;
• gooseberries.

The preparations also have significant differences that must be considered when choosing a treatment agent.

Which is better to choose?

Which tool is better to choose, "Skor" or "Chorus", depends on a combination of a number of factors.

To determine the appropriate option, you need to consider:

• growing season;
• weather conditions;
• purposes of processing;
• name of agent used for previous antifungal treatment.

"Horus" can be used in early spring when the air temperature is from +3 °С to +10 °С. Early processing at the green cone stage prevents primary contamination. The preparation provides protection even before the flowering period begins.

"Skor" starts to work at higher temperatures - from +12 °С. The fungicide is suitable for spraying plants at the budding stage. The peak of the result is observed in warm and humid weather, when the risk of fungal infections increases.

With repeated use of the drug "Skor" there is a risk of formation of resistance of pathogenic fungal to difenoconazole. "Horus" copes with pathogens resistant to the action of substances of the triazole class.

The optimal solution is the alternation of fungicides, two-stage treatment of fruit and berry trees and shrubs at an early stage with Horus, and during budding with Skor.

Fungicides can be considered partners. Alternate use of cold-resistant "Chorus" and "heat-loving" "Skor" in accordance with climatic conditions eliminates the addiction and adaptation of fungal strains to the effects of pesticides from these chemical groups.
