Instructions for the use of the Horus fungicide for grape processing and waiting times
Grape crops do not have strong immunity to fungal infections. Especially often, this attack threatens vineyards growing in temperate climatic latitudes, areas with high soil moisture. Instructions for the use of Horus, a fungicide for grapes, promises gentle protection of the plant from the spread of disease after the first treatment carried out in the spring, until the environment is favorable for the spread of the fungus.
What it is?
Horus is a fungicide product designed to combat fungi that are dangerous to the vine. Fungicide translated from Latin means "killing mushroom". Means for the same purpose include Bordeaux mixture and sulfur color, used to protect most fruit trees. Fungicides help not only to 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.
Cyprodinil is the active substance of the drug. Its mass fraction in the total composition of the product is 75%.
Cyprodinil is a pesticide that equally effectively destroys parasitic microorganisms hibernating in the vine - it destroys representatives of fungi:
- ascomycetes - over 30 thousand species of marsupial mushrooms;
- basidiomycetes - over 30 thousand species of cap mushrooms;
- Deuteromycetes are a heterogeneous group of fungi, whose ancestors were Ascomycetes and Basidiomycetes.
The effect of the drug is to destroy the infection at an early stage of development, completely destroy the ability to regenerate and reproduce.
When is it used?
Horus is applied in early spring, until the buds of the plant begin 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 with poisoning, but with the fact that the fungi are still in the sleep stage. It's easier to deal with them at this stage.
If the fungus nevertheless began to develop, affecting more and more areas of vines and leaves, then the treatment can be carried out at any stage of plant development:
- during flowering;
- ovary;
- ripening of fruits.
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, therefore, 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.
The rain that started after a few hours will not affect the quality of the spraying.
Pros and cons of the drug
"Horus" penetrates deep into a young leaf in 2-3 hours at low and high air temperatures, up to +25 ° C it works equally effectively. In extreme heat, the efficiency of the drug decreases slightly. The product 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:
- preventive;
- structuring;
- therapeutic.
The main disadvantage of "Horus" is the impossibility of qualitatively protecting adult plants from fungi. It cannot even penetrate the cuticle of an 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 processed with a solution of "Horus" of low concentration. Processing 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, granular agent is poured into it. The waiting time for the processing result 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 "Skor" preparation is required. The complexity of "Horus" lies not only in alternation, if necessary, it can be mixed with other insecticide preparations that provide protection against insect pests.
What precautions should you take?
There is no particular aggressiveness of the fungicide, but precautions for working with chemical compositions must be observed:
- children, pregnant women, nursing mothers should not be allowed closer than 15 meters during spraying;
- the same rule applies to people who are allergic to odors;
- smoking, drinking and eating are prohibited during the treatment.
Personal protective equipment when working with chemical solutions in the garden is rubber gloves, a respirator, glasses.
