This article may be useful to gardeners who use the drug "Prestige" for processing potatoes.How it effective?Harmful whether it is for the body?How does it work?The article summarizes the main issues and gardeners, of course, are the answers.All the reasons mentioned below - purely personal views of the author, based only on reliable facts and recommendations specialist with a degree in chemistry.Read on and decide - to trust or verify.
1. What is the composition is a means of "Prestige" (COP) for the treatment of potato?
preparation sold as COP (concentrated suspension) and in fasuyuschiysya liter bottles comprises imidacloprid and pencycuron (140 g / l and 150 g / l, respectively).
2. How does the drug "Prestige" for processing potatoes?
It should be noted that the selected composition is really effective against the vast majority of pests in Vol. H. Of sucking and chewing.No exception - insects in the soil.As insecticide means copes with beetles, damselflies, Lepidoptera, thrips;as a fungicide, it works against common scab and Rhizoctonia.The mechanism of action of imidacloprid lies in blocking the transmission of nerve impulses (postsynaptic membrane receptors).Pencycuron, penetrating into the cuticle of plants, inhibits the growth of mycelium (or more precisely - the germination), brakes with free sterol biosynthesis of fatty acids inside the mushroom, and not least, reduces glucose transport.The product of metabolism - hlornikotinilovaya acid-imidacloprid (an inducer of systemic resistance of plants), causing changes in physiological and biochemical level, allows the plant to easily overcome stress.In fact, the product of the "Prestige" not only protects the tubers from pests, but also preserves the next harvest from certain diseases, increasing resistance to abiotic and biotic "surprise" of the environment, increasing the germination improving shoot formation and growth of the vegetative mass, increasing the photosynthetic processes.His action shows the drug is not the first year.
3. How should the process be conducted before planting potatoes?
no difficulty here.Seed tubers (Dried) are etched prior to planting the working solution.Preferred to use a spray, after having spread the potatoes on the oilcloth.There is no need to turn the tubers.Percentages of water and the suspension in the working solution described in the instructions on the package.Tuber bacterial wet rot, do not process or planted (requires sorting).
4. How long does matter "Prestige" for processing potatoes?
from wireworm agent protects the whole period of growth vegetables from beetle (Colorado) - at least two months from the time of germination (and the longer the duration, the less effect), by aphids - 40 days from day seedlings from scab with Rhizoctonia - timegrowth grasping the flowering period.
5. Can the drug "Prestige" for processing potatoes combine with pesticides from other manufacturers?
works very effectively when used together means "Prestige" and "Maxim" 025 FC.However, this is just an observation.The study was conducted subsequently tubers, however guarantee that harmful substances are not available, no.Combining the drug with other pesticides undesirable.
7. Is the drug "Prestige" for processing potatoes safe?
first two months from the day that made processing potato tubers categorically can not be used.Manufacturer («Bayer») ensures that you can easily enjoy the young potatoes after only 53 days after treatment.And that, really?Imidacloprid, as mentioned, is the basis of the drug.He is now recognized in almost all countries, as indeed very effective.Toxicity - average (moderate poison).Acting on warm-blooded creatures (including man), causing tremors, disturbed coordination, weight loss during diarrhea.It has an impact on the reproductive organs (increases the likelihood of spontaneous abortion and the likelihood of problems with the skeleton in the offspring).It possesses and mutagenic.Being chronically and acutely toxic, imidacloprid become safer over time in relation to those pests that have been able to develop a resistance to it.According to a study of the European Union during the decomposition DT50 (Imidacloprid) averages between 77 and 200 days (field DT 50 - 174 days, laboratory DT 90 - 717 days).It turns out that potatoes laid down in the cellar for the winter, it is really safe.But statements about the safety of a 53-day deadline in doubt.Treat any potatoes "Prestige", you decide.However, when comparing the actions of other drugs that require repeated handling, opt for it is obvious.
8. drug "Prestige" for processing potatoes (feedback on its use).
Most gardeners, try the drug, they agree that it is really effective.Tubers hardly affected scab and wireworm (except varieties "Grouse" and "Wizard").As for the Colorado potato beetle, the insect larvae begin to appear in the main by the end of flowering.
