Nurel D: instructions for use and composition of the insecticide, dosage and analogues

Crops are damaged not only by diseases provoked by pathogenic microorganisms. Insect pests also damage crops. And while small homeowners can deal with pest infestation by hand, farmers who grow crops for sale are forced to use chemicals. The instructions for Nurel D indicate that the insecticide is designed to combat a wide range of pests.

Purpose of the drug and release form

Insecticide "Nurel D" refers to protective chemicals with a wide spectrum of action, it includes two active components at once.This is chlorpyrifos at a concentration of 500 grams per liter of the drug and cypermethrin at 50 grams per liter. The first active ingredient 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 on small beds.

Designed by "Nurel D" for the destruction of garden pests and crops from parasites. The list of pests against which the insecticide is effective includes insects such as thrips, aphids, leafworms, weevils, suckers, leaf beetles, sawflies and others.

How it works

Thanks to two active ingredients in the composition of the insecticide, it 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 into plant tissues 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, so it does not have a systemic effect.

Advantages and disadvantages of the tool

Having evaluated in practice the working qualities of "Nurela D", farmers and summer residents identified several advantages of the insecticide.

The advantages of a chemical agent include the following points:

• 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 against pests after processing;
• convenient formulation and packaging of the drug;
• equal effectiveness in killing both adults and larvae;
• weak susceptibility to the effects of precipitation and weather;
• lack of resistance, subject to the application of the drug.

Of the shortcomings, only one point can be noted - treatment with the drug cannot be carried out during the flowering period of the cultivated plant.

Cooking and instructions for use

The effectiveness of the insecticidal agent directly depends on compliance with the consumption rates specified by the manufacturer in the instructions for use.

Recommended application rates for different crops are shown in the table:

Cultivated plant

Preparation of the working fluid is carried out in two stages:

1. A liter of water is poured into the container and the required amount of insecticidal preparation is added. Mix thoroughly until the chemical is completely dissolved.
2. After that, 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 substances do not lose their effectiveness. Spraying of cultivated plants is carried out at a temperature of 10 to 25 degrees Celsius, with 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.

Safety precautions

The Nurel D insecticidal drug belongs to the second class of toxicity, so safety rules must be observed when working with it.The person who carries out the treatment must wear protective overalls, gloves and a scarf. A respirator is used to prevent chemical vapors from entering the respiratory tract.

After finishing work, all clothes are washed and hung outside. A farmer takes a shower to wash off drops of an insecticidal drug that he accidentally gets on. If the chemical gets into the eyes, rinse them with plenty of clean water and immediately go to the nearest clinic for medical assistance. If a person accidentally swallowed a small amount of insecticide, drink activated charcoal and also go to a medical facility.

Compatibility with other substances

After conducting a chemical compatibility test, Nurel D is allowed to be used with most growth stimulants, insecticides and fungicides.

The active components of the chemical lose their working qualities when combined with alkaline preparations and copper compounds.

Insecticide storage

The instructions for use indicate that the insecticidal preparation retains its qualities for 3 years from the date of production, provided that the packaging is intact. 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.

Analogues

You can replace the insecticide with chemicals such as "Volley", "Sufron" or "Shtefotruta".
