Fungicide "Horus" for grapes: instructions for use when to process

Grape crops do not have strong immunity to fungal infections. Especially often this misfortune threatens vineyards growing in temperate climatic latitudes, areas with high soil moisture. The instructions for use of Horus, a fungicide for grapes, promise gentle protection of the plant from the spread of the disease after the first treatment carried out in the spring, until the environment has become favorable for the spread of the fungus.

What is this?

"Horus" - a fungicide group product designed to combat fungi that are dangerous to the vine.Fungicide in Latin means "killing fungus". Means of the same purpose include Bordeaux mixture and sulfur color, used to protect most fruit trees. Fungicides help not only protect the plant from fungal infections, they are also used to treat the premises in which the fruits will be stored, which helps to preserve the berries for a long time.

The drug "Horus" is used for grape diseases:

Oidium.
Mildew.
Powdery mildew.
Leaf spots.
Fruit and gray rot.

The active substance of the drug is cyprodinil. Its mass fraction in the total composition of the product is 75%.

Cyprodinil is a pesticide that equally effectively destroys parasitic microorganisms wintering in the vine - it destroys representatives of fungi:

ascomycetes - over 30 thousand species of marsupials;
basidiomycetes - over 30 thousand species of cap mushrooms;
Deuteromycetes are a heterogeneous group of fungi whose ancestors were Ascomycetes and Basidiomycetes.

The action of the drug is to destroy the infection at an early stage of development, the complete destruction of the ability to regenerate and reproduce.

When applied?

Applied "Horus" in early spring, until the moment when the buds of the plant began to swell. This is not due to the danger of the drug for the plant or its accumulation in the fruits of the future harvest, which could threaten poisoning, but to the fact that the fungi are still in the dormant stage. At this stage, they are easier to deal with.

If the fungus nevertheless began to develop, affecting more and more areas of the vine, leaves, then the treatment can be carried out at any stage of plant development:

during flowering;
ovaries;
fruit ripening.

The peculiarity of the drug produced by the Swiss manufacturer "Syngenta" is that "Horus" affects only the lesions, it does not penetrate deep into the vine, respectively, does not get into the juice and does not spread throughout the plant. Spraying of plants is carried out in dry weather, which accelerates its penetration into young shoots and leaves.

Raining after a few hours will not affect the quality of the spraying.

Pros and cons of the drug

"Horus" penetrates deep into the young leaf in 2-3 hours at low and high air temperatures, up to +25 ° C it acts equally effectively. In extreme heat, the performance of the drug is somewhat reduced. The agent is not toxic to the plant.Its consumption is relatively low. The low mobility of the components also refers to the positive qualities of the fungicide, they will not be carried away from the plant by groundwater.

The tool is used as:

prophylactic;
structuring;
treatment.

The main disadvantage of "Horus" is the impossibility of qualitatively protecting adult plants from fungi. It cannot even penetrate the cuticle of the old leaf. Because of this feature, it is recommended to apply the fungicide in the spring, until the leaves of the grapes have gained strength.

Instructions for use

Grapes should be treated with a solution of "Horus" of low concentration. The processing of one hundred square meters of vineyard will require 2 liters of water and 6 g of dry product. First, water is poured into the sprayer, a granular agent is poured into it.The waiting time for the result of processing does not exceed 2-3 hours.

Compatibility with other drugs

The action of the drug lasts 1-2 weeks. After that, re-treatment with the drug "Skor" is required. The complexity of "Horus" is not only in the alternation, if necessary, it can be mixed with other insecticide preparations that provide protection against insect pests.

What precautions should I take?

The fungicide is not particularly aggressive, but precautions for working with chemical compounds must be observed:

children, pregnant women, nursing mothers should not be allowed closer than 15 meters during spraying;
the same rule applies to people allergic to smells;
Smoking, drinking and eating are prohibited during processing.
