For the successful fight against fungal and bacterial diseases of cultivated plants, special protective agents, fungicides, have been created. Timely processing of seeds during sowing, seedlings and adult plants will save them from death and get a high yield.
Among a wide variety of fungicides, Previkur Energy is a special place. Reviews of amateur gardeners and farmers indicate its high efficiency and safety.
Description
The drug is produced by the German company Bayer Garden. The tool is considered an innovative two-component fungicide with a protective and pronounced growth-promoting effect. When treating plants from infection, their growth and development is simultaneously enhanced due to the Previkur Energy preparation. The use is associated with the function of active substances, which are propamocarb hydrochloride and aluminum phosphate.
The first component of the systemic action belongs to the class of carbamates. The second substance has an absolute systemic effect and relates to organophosphorus fungicides. The drug is considered an improved form of the latest generation of the well-known Previkur product, which contains only propamocarb hydrochloride.
Release form
A fungicide is produced in the form of a water-soluble concentrate (VK) in the form of a suspension. 1 liter contains 530 g of propamocarb hydrochloride and 310 g of aluminum phosphate, and the concentration of the active component, propamocarb phosphate, is 840 g per 1 liter. Sold in bottles of 1000 ml or 10 ml of concentrate.
Features of the drug
The Previkur Energy fungicide refers to innovative technologies that use the optimal combination of the two active components of propamocarb hydrochloride and aluminum phosphate. The new combination is based on combining chemicals of various nature with hydrophilic bonds, which can improve fungicidal properties aimed at suppressing diseases.
The drug is considered a concentrated solution, the only liquid form of fosetil. Available in the form of a transparent liquid, the hydrogen index of which has a neutral value.
In addition to the protective properties, the Previkur Energy preparation has positive reviews regarding the stimulation of the growth of the root system and aerial shoots of the plant. It makes them stronger and healthier.
To suppress a large number of fungal diseases of various types, the action of the Previkur drug is directed. Application leaves a lasting effect. This reduces the number of treatments.
Both active components of the drug are osteomycetes, their spectrum of action practically coincides, they differ only in the mechanism of action on the infection.
The drug is versatile, a diluted solution in a certain concentration can be sprayed, just water or irrigate drip plants.
How does fungicide work?
The mechanism of action of the tool is based on the properties of its active components. For Previkur Energy fungicide, the instructions for use describe the effect of each active substance.
The properties of propamocarb are associated with interruption of the formation of the cell membrane of fungi and inhibition of mycelial growth, the formation and germination of spore-bearing cells. This substance has high activity against fungal diseases during spillage or spraying. Another important property is associated with stimulation of growth in the early stages of crop development.
Fosetil prevents spores from germinating and penetrating pathogens into plants after prophylactic treatment. Therapeutic spraying leads to blocking the development of mycelium and the formation of spores. The uniqueness of the substance lies in the method of movement through the plant and its mechanism of action.
Penetrating into plants, fosetil is distributed acropetically (from bottom to top) and basipetally (from top to bottom), reaching the desired organ, whether it is young shoots or roots. The time of complete saturation of the seedling with the active component does not exceed 60 minutes. The action of fosetil is aimed at enhancing the protective reactions of the plant, which characterizes SPU (System Acquired Resistance).
What microorganisms affects
For Previkur, the instructions for use contain information on the effective use against pathogenic organisms that cause root and root rot, powdery mildew or peronosporosis, late blight. First of all, pathogenic fungi Pitium and Phytophthora are referred to them.
The drug "Previkur Energy" is used for the defeat of vegetative aboveground organs in such fungi as Bremie lucius and Peronospore.
The effectiveness of the agent against mold Fusarium and bacterial cells from the genus Pseudomonas has been confirmed.
Action duration
Up to 14 days the protection of the Previkur Energy preparation works. The instruction for use recommends that the duration of action be associated with the degree of infection of plants and weather and climate conditions that can weaken the fungicidal properties of the drug.
Emergence of sustainability
The likelihood of addiction of the treated plants to the Previkur Energy tool is very low. The use of fungicide is based on the mechanism of action of its active components in the concentrate, which is associated with the inhibition of metabolic reactions in fungal cells of different levels, different components of the drug do not affect the same metabolic processes. That is why resistance can develop in rare cases.
To eliminate the risk of addiction, treatment is carried out with drugs, which contain substances with different chemical effects.
What is it used for?
The Previkur fungicidal agent is recommended for use in preparing the soil before planting, for the prevention and treatment of seedlings in greenhouses. These measures allow you to get the maximum effect from the drug for growing healthy crops.
About Previkur Energy's protective agent, reviews indicate that it has specific activity against most fungi that can harm seeds, seedlings, stems, leaves and fruits of indoor and outdoor plants.
The first treatment with the drug is used for spilling the soil after sowing seeds. The following application of the disinfecting solution is carried out for strait seedlings in order to obtain strong, healthy plants and prepare for the stress state during transplantation to a permanent place.
Treatment of transplanted seedlings with the Previkur Energy fungicide begins after the restoration of homeostasis in plants, which occurs a week later. Carrying out activities is connected with the addition of diluted concentrate of the root system every two weeks.
It is allowed to use the agent for spraying the vegetative organs of plants on which fungal lesions are present.
Application features
The Previkur fungicide is introduced into a moist substrate so that its active substance easily penetrates the plant's root system. The drug has unique stimulating capabilities, after processing the seedlings are distinguished by enhanced growth and development.
About Previkur, the reviews are mostly positive. Users indicate the best protection during preventative treatment, in which the development of the disease is prevented and the plant is stimulated. When diluting the concentrate in water, it dissolves almost all after thorough mixing. For every 6 or 7 liters of liquid, 10 ml of suspension is consumed, which corresponds to one bottle.
It is best to carry out the processing in January, February, March, April, May, June, then take a break, after which to start in November and December.
