Agricultural crops are damaged not only by diseases caused by pathogenic microorganisms. Insect pests also cause damage to the crop. And if owners of small plots of land can cope with the invasion of parasites manually, then farmers who grow crops for sale are forced to use chemicals. The instructions for Nurel D indicate that the insecticide is intended to combat a wide range of pests.
Purpose of the drug and release form
The insecticide "Nurel D" is a broad-spectrum protective chemical; it contains two active components. These are chlorpyrifos in a concentration of 500 grams per liter of the drug and cypermethrin in an amount of 50 grams per liter. The first active substance belongs to the chemical class of organophosphorus compounds, the second belongs to the group of pyrethroids.
The manufacturer produces the insecticide in the form of an emulsion concentrate, which is packaged either in 5-liter plastic canisters or in 7-ml ampoules for use in small beds.
“Nurel D” was developed for the destruction of garden pests and agricultural crops from parasites. The list of pests against which the insecticide is effective includes insects such as thrips, aphids, leaf rollers, weevils, copperheads, leaf beetles, sawflies and others.
How does he work
Thanks to two active ingredients in the composition, the insecticide affects pests in several directions at once. “Nurel D” has a contact, intestinal, fumigant and local-systemic effect on insects.
After application, the drug penetrates the plant tissue and affects both adult pests and larvae. Cypermethrin is characterized by a paralyzing effect, and chlorpyrifos is considered a cholinesterase inhibitor. The insecticide does not spread to all parts of the crop and therefore does not have a systemic effect.
Advantages and disadvantages of the product
Having assessed in practice the working qualities of Nurel D, farmers and summer residents identified several advantages of the insecticide.
The advantages of the chemical include the following:
- a large list of insect pests against which the insecticide works effectively;
- speed of penetration into plant tissues;
- destruction of parasites both above the ground and in the ground, as well as in hard-to-reach places - under foliage, under creeping shoots;
- quite a long period of protection from pests after treatment;
- convenient formulation and packaging of the drug;
- equal effectiveness in killing both adults and larvae;
- low susceptibility to the effects of precipitation and weather;
- absence of resistance, subject to compliance with the drug application standards.
Among the disadvantages, only one point can be noted - treatment with the drug cannot be carried out during the flowering period of the cultivated plant.
Preparation and instructions for use
The effectiveness of the insecticide directly depends on compliance with the consumption rates specified by the manufacturer in the instructions for use.
Recommended application rates for different crops are presented in the table:
| cultivated plant | Insecticide rate per hectare of field | Consumption of working solution and frequency of treatments |
| Sugar beet | 800 ml | From 200 to 400 liters per hectare of plantings, treatment is carried out once |
| Grape | From 1200 to 2800 ml of the drug, depending on the number of pests in the area | From 600 to 1000 liters per hectare, twice processed per season with an interval of a month |
| Potato | From 1500 to 2000 ml | From 200 to 400 liters per hectare, twice per season |
| Vegetables | From 500 to 900 ml | From 200 to 400 liters, twice during the growing season |
The preparation of working fluid is carried out in two stages:
- A liter of water is poured into the container and the required amount of insecticidal preparation is added. Stir thoroughly until the chemical is completely dissolved.
- After this, pour in the remaining water and mix again until smooth.
It is necessary to prepare the working fluid before starting the treatment so that the active ingredients do not lose their effectiveness. Spraying of cultivated plants is carried out at temperatures from 10 to 25 degrees Celsius, at a minimum wind speed, so that drops of the chemical do not fall on neighboring areas.
After completion of work, the sprayer is washed with water, and the remaining liquid is disposed of in accordance with safety requirements.
Security measures
The insecticidal drug "Nurel D" belongs to the second class of toxicity, so when working with it you must follow safety rules. The person carrying out the treatment must wear protective overalls, gloves and a headscarf. To prevent chemical vapors from entering the respiratory tract, use a respirator.
After finishing work, all clothes are washed and hung outside. A farmer takes a shower to wash off any drops of insecticide that accidentally fall on him. If the chemical gets into your eyes, wash them with plenty of clean water and immediately go to the nearest clinic for medical assistance. If a person accidentally swallows a small amount of insecticide, drink activated carbon and also contact a medical facility.
Compatibility with other substances
After a chemical compatibility test, Nurel D is allowed to be used with most growth stimulants, insecticidal and fungicidal drugs.
Insecticide storage
The instructions for use indicate that the insecticidal preparation retains its properties for 3 years from the date of production, provided that the packaging is not damaged. It is recommended to store Nurel D at a temperature of 5 to 40 degrees Celsius in closed utility rooms where sunlight does not penetrate.
Analogs
You can replace the insecticide with chemicals such as “Valley”, “Sufron” or “Shtefotruta”.
