Corado is a chemical preparation for the destruction of the Colorado potato beetle and potato ladybug in personal subsidiary plots, on private garden and vegetable gardens. Also effective against other pests. This insecticide is officially registered by the state and is freely sold in stores. Corado is a pesticide (that is, a pesticide), and its use is possible only clearly according to the instructions.
Description and characteristics of the drug Corado
The traditional packaging - with a blue background - has recently been replaced by a brighter orange-brown. The image of Colorado beetles and their larvae remains unchanged.
Corado Insecticide Manufacturer - the Russian company "Your economy" (head office is located in Nizhny Novgorod). Liquid product; for ease of dosage, it is packed in packaging of various sizes:
- ampoule 1 ml in a bag;
- box of 5 ampoules of 1 ml;
- 10 ml bottle per package;
- bottle of 25 ml in a box.
Each individual package is supplied with instructions.
Recently, LLC "Your economy" has also been producing the drug "Corado - protection against onion and carrot flies": 2 ampoules of 2 ml in a single blister.
Historical reference
Liquid in ampoule or bottle - a solution of a substance called imidacloprid at a concentration of 200 g / l. This newest chemical was developed by the German pharmaceutical company Bayer. Her sole worldwide patent recently expired, and now imidacloprid can be freely produced and sold by any enterprise. A large number is produced by China and supplied for packaging to other countries.
Imidacloprid belongs to the chemical group of neonicotinoids - artificial analogs of the natural nicotine alkaloid.
Composition
The alkaloid nicotine is found in the tops of plants of the Solanaceae family. There is especially a lot of it in tobacco. Even in antiquity, it was noticed that tobacco infusion had a detrimental effect on many insects. In the twentieth century, artificial pure nicotine was synthesized, but it turned out to be a strong poison not only for insects, but also for humans. Scientists continued their research and developed new substances - neonicotinoids, in small doses poisonous to insects, but relatively safe for humans and animals.
In the modern world, 5 main neonicotinoids are used to combat insects in everyday life and in agriculture:
- thiacloprid (only for large agricultural enterprises),
- thiamethoxam (Aktara),
- acetamiprid (Stozhar, Mospilan),
- clothianidin (Apache, Bushido, Punisher),
- imidacloprid (several dozen drugs).
General properties of neonicotinoids
- High toxicity for many insects that gnaw leaves and suck plant juices (including for the Colorado potato beetle and its larvae).
- Virtually no "addictive" effect is observed: insects do not adapt to poison.
- The chemical enters the plant and spreads to stems, leaves, flowers. It stays there for 2-4 weeks. Almost does not get into fruits and tubers.
Neonicotinoids are highly toxic to bees, bumblebees and other beneficial pollinating insects. These substances are banned in many countries around the world. They can not be used on flowering plants and near them. If a plant is sprayed before flowering, then the pollen of its flowers will be fatal to bees for almost a month. There is evidence that regular treatments with neonicotinoids reduce the number of earthworms.
Features of imidacloprid
Since imidacloprid is not protected by a world patent (unlike other "brothers"), it is available to any manufacturer and packer. Due to competition, it has the lowest price in the world market. This chemical is widely used to treat plants from many insects: aphids, greenhouse whiteflies, various beetles, flies, thrips, soil pests.
It is especially appreciated that the substance can be applied not only by spraying, but also during watering, processing of seeds and tubers. It will spread through the vessels of the plant and kill any insects that eat leaves, stems, processed grains or tubers within 2-4 weeks.... The poison weakly penetrates the growing fruits.
Imidacloprid is found in many agrochemicals. It is it that is contained in the popular seed potato dressing agents (Prestige, Tabu, etc.).
Analogs
Imidacloprid at a concentration of 200 g / l is named differently by each manufacturer. The company "Your economy" named it Corado, and other firms: Confidelin, Komandor, Tanrek, Zubr, Imidor, Biotlin, Iskra Zolotaya. If Corado is recommended only against the Colorado potato beetle and apple aphid, then other drugs of a similar composition fight against various aphids, flower beetles, thrips, bedbugs, greenhouse whitefly.
These funds are interchangeable, and Corado has a wider spectrum of action than indicated in the recommendations of its supplier.
That is why the firm "Your economy" released two more preparations with the same content - 200 g / l of imidacloprid: "Kortlis" (against aphids on currants, apple trees and potted crops) and "Corado - protection against onion and carrot flies". The same manufacturer offers a two-part chemical based on Corado - "Beetle number 1". To combat the Colorado potato beetle, Stozhar is also recommended, in which there is another neonicotinoid - acetamiprid: it is believed that it is less harmful to bees.
Instructions for using the drug from the Colorado potato beetle
The use of the product is wiser only when there is a real danger to the crop. It carries environmental risks and is not suitable for thoughtless prevention.
Storage conditions
Use within three years from the date of manufacture.
Store indoors, where it is not colder than -5 degrees and not higher than +25. Do not burn, do not burn.
Objects of influence
The chemical causes paralysis of the nervous system of insects.
The Colorado potato beetle and its larvae die from direct exposure to a pesticide (contact effect), as well as from eating foliage (intestinal poisoning). Ovipositions do not suffer, but hatched larvae also die from food poisoning (greens remain poisonous for almost a month after processing).
The 28-point potato ladybug is a dangerous beetle that destroys potato tops in Primorye and Sakhalin. Fighting it is similar to that of the Colorado potato beetle.
Aphids on an apple tree are destroyed at any stage of the growing season. It is advisable to capture it in the initial period of settlement.
The biological insecticide Fitoverm copes with any aphid (analogues - Iskra Bio, Akarin); it is safer for the environment.
Processing time
- The treatment is carried out once, at the first detection of pests on plants.
- Avoid windy weather.
- It should be at least 4 hours before it starts to rain. Then the chemical will penetrate into the plants, and precipitation will no longer weaken its action.
- They choose evening (after 6 pm), in extreme cases - morning (before 10 am). This makes it less sun exposure and safer for bees.
- Temperature does not play a big role (the optimal range is wide: from +10 to + 26).
Application technology
The pesticide is applied by spraying. The spray should be fine (a broom will not work).
- An ampoule (bottle) contains a liquid concentrate, which is diluted with water - first in a small amount, then brought to the required volume. Prepare a solution before work, do not store for a long time.
- Recommended dosage: 1 ml of concentrate per 4 liters of water.
- Planting does not need to be soaked abundantly. Sufficient surface spraying with a consumption of 4 liters of solution per 1 hundred square meters. If at least a third of the plant is processed, the tissue will have the desired concentration.
- Corado can be mixed with fungicides (for plant diseases), except for copper-containing preparations.
Impact
In the very first hours, insects almost stop their vital activity. Complete death occurs in 2-3 days, maximum - after 5. Protection from emerging larvae and newly arriving individuals lasts at least two weeks, up to a month.
Precautions
- Usually, the drug does not irritate the skin, mucous membranes of the eyes and mouth, but it is better to protect yourself with standard protective clothing.
- All work must be carried out in the absence of children and pets.
- It is forbidden to spray flower plants visited by pollinating insects.
- Do not splash other crops, especially green crops. They will quickly penetrate into plants, they cannot be washed off with water. Heat treatment (cooking, frying) will not help either. The pesticide is destroyed only from time to time: in the plant after a month, in the soil almost after a year.
- Corado is fatal to aquatic life. Do not spray near water bodies, all the more to send the remains of the solution into them. They are poured into a hole, covered with earth.
- It is allowed to go to the treated plantation three days after processing. After 10 days, the concentration of poison in the leaves and tubers decreases. For insects, foliage will be poisonous for another 10-20 days.
- Imidacloprid has a 3rd (middle) hazard class for humans, mammals, animals, birds. The (accidental) consumption of concentrate and freshly processed herbs should be avoided. Poisoning symptoms: trouble breathing, trembling limbs, lethargy; in this case, an urgent visit to a doctor is required, otherwise the liver may suffer. Long-term food exposure of small doses can disrupt the endocrine system.
It is recommended to wait at least three weeks after spraying before digging potatoes.
Corado is very effective against the Colorado potato beetle. Acts quickly, does not cause addiction, reliably protects plantings for another month. The pesticide is used strictly when necessary, with thorough observance of all safety rules.
