The agricultural market offers a wide range of various chemical agents to combat diseases caused by fungal pathogens, which differ from each other in composition and mechanism of action. The use of a fungicide for cucumbers, according to the instructions for use, is mandatory in the early stages, since it is extremely difficult to get rid of them in the future. Even before planting a vegetable crop, you should familiarize yourself with the list of the best drugs and the principles of their effects.
Purpose of fungicides and their types
Fungicides are used to eliminate the source of fungal infection and further protect the crop plant. Based on the nature of the effect, two types of fungicides are distinguished: protective and therapeutic. They should be used when characteristic symptoms are detected, as well as for preventive purposes.
Principle of influence and function
The active components of fungicides penetrate plant cells and identify pathogenic microorganisms. Next, they prevent further cell division, inhibit metabolic processes and subsequently promote the elimination of broken down pathogen residues. Many drugs also build immunity in the culture against this type of infection..
The best drugs
Among the large range of existing products, several of the most effective fungicides for cucumbers can be identified.
"Quadris"
A modern progressive remedy that can protect cucumbers from fungal infections. The main advantages of the drug "Quadris" include:
- protection against major cucumber diseases such as powdery mildew and downy mildew;
- ensuring sustainable and long-lasting protective action;
- increased productivity due to increased and prolonged photosynthesis;
- increasing the level of moisture absorption by vegetable crops;
- improving product quality and profitability of growing vegetables.
The fungicide "Quadris" is capable of destroying the pathogen during the incubation period. Thanks to this drug, you can quickly stop the spread and development of infection in the cucumber bed. To do this, spray the vegetable crop during the growing season before and after flowering with an interval of 7-14 days.The consumption of the working solution for open ground cucumbers is 800 l/ha, and when growing vegetables in a greenhouse - up to 1500 l/ha.
"Thanos"
An effective means of contact-systemic action for the treatment and prevention of fungi at different stages of the growing season of a cultivated plant. Distinctive features of the fungicide:
- resistance to washing off;
- productive protection against late blight and alternaria;
- instant impact from the first minutes after spraying;
- duration of therapy for fungal infection;
- profitable expense.
The Thanos fungicide kills all spores within a minute, penetrates the plant cells and stops the development of infections. Vegetable crops are sprayed no more than 5 times during the rainy summer; in the dry season, you can limit yourself to 2 procedures.
The working fluid consumption is 1 liter per 10 square meters.
"Strobe"
One of the new generation drugs is “Strobi”, which has a wide range of effects on pathogens of fungal diseases of cucumbers. Benefits of the fungicide:
- Possibility of use during flowering;
- resistance to rain and sudden temperature changes due to the high rate of penetration into the plant;
- low level of toxicity for animals and safety for bees;
- used not only for the treatment, but also for the prevention of diseases such as powdery mildew, peronosporosis, late blight;
- the price corresponds to the effectiveness of the drug.
Treatment of cucumbers with the Strobi fungicide should be carried out during the growing season, preparing a solution in the proportion of 2 g of the product per 10 liters of water. It is recommended to perform the procedure in dry, windless weather.
"Infinito"
A dual action product that is used for prevention and in case of infection. The positive qualities of the fungicide include:
- quick disposal of spores, instant penetration of the pathogen into the body;
- complete stop of the development of peronosporosis and powdery mildew on the first day;
- guaranteed protection and long-term further impact;
- positive effect on the growth and development of cultivated plants.
During the growing season it is allowed to process no more than 2 times. To prepare the working solution, you need to dilute 15 ml of Infinito fungicide in 5 liters of water. Harvest can only be done 10 days after spraying.
"Topaz"
An effective new generation fungicide that is actively used to destroy fungal pathogens in a short time. The drug has many advantages:
- the duration of the protective effect exceeds 2 weeks;
- destruction of the powdery mildew pathogen within 3 hours;
- resistance to watering and rain;
- resistance to temperature changes.
When growing cucumbers in a greenhouse, the concentration of the working fluid should be 2.5 ml per 10 liters of water. When using the drug for vegetables growing in open ground, the same amount is diluted in 8 liters. This volume is enough to process 1 hundred square meters of vegetables.
"Kurzat"
An effective contact agent for protecting many crops from fungal infections. It differs from other drugs:
- ability to resist late blight, dry spotting, downy mildew;
- duration and rapid action of the main components in the composition;
- safety for animals, humans and many cultivated plants.
The drug creates a protective coating on the surface of vegetative organs and penetrates the plant cells, identifies the pathogen and destroys it. Fungicide "Kurzat" is available in the form of a soluble powder, packaged in paper bags.For 1 hectare of plantings, about 2 kg of product dissolved in 400-600 liters of liquid will be required.
"Acrobat"

- protection for 20 days from re-infection;
- lack of toxicity to living organisms;
- Possibility of use in combination with other chemicals;
- the permissibility of using water bodies and sanitary zones nearby.
Spraying of cucumbers is carried out at the first detection of symptoms of fungal infections. For 1 hectare of cultivated plants there are 7 liters of working solution. For 1 season, the minimum number of treatments does not exceed 5.
"Hometzin"

Fungicide "Bravo"
Contact herbicide that prevents the development of infections in the early stages. The substance envelops the surfaces of vegetative organs and prevents the further development of pathogens. Has many advantages:
- versatility in use against a wide range of lesions;
- possibility of combination with other chemicals;
- resistance to washing off;
- prevents resistance in fungal pathogens;
- If the dosage is observed, it does not show toxicity to all types of plants.
