For more than 10 years, the new generation fungicide Brunka has been successfully used in agriculture, attracting with its simple method of application, excellent reviews and reasonable prices. The three active components included in its composition provide multifunctional action against fungi and pests.
The drug has the properties of an insecticide and fungicide, which makes it a powerful means of comprehensive plant protection. Brunka is intended for the treatment of fruit and ornamental trees and vineyards.
Chemical composition of the drug
Each of the components contained in Brunka fungicide has unique characteristics.
Lambda-cyhalothrin is a contact insecticide effective against a wide range of pests, including mites. Its mechanism of action is based on suppressing the functions of the nervous system when it enters the insect’s body.
Imidacloprid belongs to a class of synthetic neonicotinoids. Once in the body of pests, they have a paralytic effect on their nervous system and suppress the digestive function. Maximum activity of the substance is observed 3-5 days after treatments. The duration of the protective effect lasts quite a long time - about a month. Does not cause resistance.
Aluminum phosphide is an inorganic substance that, when interacting with water, forms aluminum hydroxide and hydrogen phosphide. Phosphine has a toxic effect on the nervous and respiratory systems of insects. Phosphine resistance may develop in some pest species.
Features of the action
Brunka fungicide, thanks to the combined action of three elements, has the properties of an insectoacaricide with a high ability to penetrate the body of insects. And the contact action of lambda-cyhalothrin protects the leaves from caterpillars and larvae.
During the breakdown of the active compounds of the drug Brunka, microelements such as phosphorus, aluminum and copper are released, which serve to stimulate plant development.
The components of Brunka fungicide are activated at different ambient temperatures:
- for lambda-cygalotropin, 2 degrees Celsius is enough;
- imidacloprid begins to act at 6 degrees Celsius;
- The decomposition of aluminum phosphide begins upon contact with moisture and accelerates with increasing temperature.
Considering these features of the fungicide, the best temperature range for spraying will be 12-20 degrees.
Number of treatments
Two sprayings with Brunka per season are enough for effective plant protection:
- the first is carried out in early spring, before the buds have time to open;
- the second - in late autumn, when the plant is preparing for winter.
Sometimes, if the trees are very neglected, another treatment with Brunka is allowed. It is usually carried out after flowering has ended.To minimize the harm caused to plants, when spraying again, the dosage of the drug is halved.
The commercial form of release of Brunka fungicide, depending on the method of application and price, is a soluble concentrate with the following volume:
- 30 ml;
- 150 ml;
- 350 ml.
This packaging is very convenient for summer residents and amateur gardeners, but farmers need significant volumes. The cost of the smallest package of Brunka fungicide is 100 rubles. For basic treatments, the dose of the substance is 30 ml per bucket of water. First, a measured amount of the drug is dissolved in a small amount of water, then the mixture is diluted to the required volume. The prepared working solution can be stored for no more than a day. Remains of used substance must be disposed of.
Advantages of the drug
The advantages of Brunka fungicide are:
- complex impact with a wide spectrum;
- destruction of wintering pests;
- blocking germinating spores of pathogenic mycelium;
- the absence of harmful decomposition products that have a detrimental effect on trees and fruits;
- release of useful microelements during decay, acting as foliar feeding;
- a small number of treatments, unlike other drugs;
- lack of herbicidal properties and severe burns of foliage;
- weak degree of coloring compared to other substances;
- Possibility of use at the initial stage of bud opening.
The drug Brunka also has some disadvantages:
- it has a slight coloring effect, but to a lesser extent than other drugs;
- The fungicide is quite expensive, although its price is justified.
It has also been noted that the Brunka fungicide, according to reviews, slows down the blossoming of leaves for a short time, but in the future this factor is quickly compensated.
Safety regulations
Brunka fungicide is a drug of moderate toxicity to humans and animals, so handling it requires special care:
- Direct contact with the substance should be avoided;
- it can only be transported in a hermetically sealed container;
- when spraying trees, the presence of children and animals in the immediate vicinity of the site is not allowed;
- containers that were used to prepare a working solution of Brunka fungicide and subsequent spraying cannot be used for other purposes;
- Before starting work, you need to check the serviceability of the sprayer;
- When preparing the solution and processing plants, it is necessary to use personal protective equipment - rubber boots and gloves, a respirator, goggles, a work coat or overalls.
When treating plants with Brunka fungicide, it is important to choose the right time:
- Spraying should be carried out in the morning or evening;
- if the treatment is carried out during the daytime, you need to choose a cloudy day - in hot weather the solution quickly evaporates, and its toxic fumes saturate the surrounding air;
- It is not recommended to spray in windy weather.
Protective measures after processing
Certain recommendations should be followed after spraying is completed:
- remove protective clothing and equipment and take a shower;
- only after this can you smoke or eat;
- It is useful to drink a glass of milk to neutralize some of the toxins that have entered the body;
- drinking alcohol can enhance the effect of poisons;
- You can start working in the garden only three days after treatment.
Reviews from gardeners
Numerous positive reviews confirm the high effectiveness of the drug Brunka.
Conclusion
If you strictly follow all the recommendations specified in the instructions for use, the Brunka fungicide will become a reliable protector of the garden.
