Preparative form

The drug is produced as a suspension concentrate. It is sold in 0.5 liter plastic containers.

Active ingredient

The active ingredient of the substance is fenpyroximate. 1 liter contains 50 grams of this ingredient.

Mechanism of action

"Orthus" provokes rapid paralysis of ticks. Moreover, it works at all mobile stages of their development. The composition can be used at the stage of larvae, nymphs and adults. The effectiveness of the substance is due simultaneously to 3 key processes:

• nerve impulse - this disrupts the transmission of data through the postsynaptic membrane of the nervous system to various organs of the parasite;
• oxidative phosphorization - in this case, the production of ATP molecules is disrupted due to the oxidation of molecules of organic elements, which leads to complete energy depletion;
• violation of the hormonal status - this changes the life cycle of the parasite, and the end of the stages of its development is excluded.

If young pests appear after processing from previously laid eggs, they immediately die. This is due to the contact of parasites with the remnants of the product.

Key benefits of Orthus include:

• quick paralysis of all mobile stages of tick development and a sharp decrease in oviposition;
• extensive range of acaricidal actions;
• quick effect and lasting effect - usually 1 treatment per season is enough;
• destruction of ticks at various stages - larvae, nymphs, adults;
• pronounced ovicidal effect;
• lack of development of resistance in ticks that are resistant to other acaricides;
• high resistance to the negative impact of external factors - high temperature, rain, ultraviolet radiation;
• no negative effect on entomophages, including beneficial insects and predatory mites;
• compatibility with various protective agents that are used for processing apple trees, hops and grapes;
• possibility of simultaneous use with growth regulators and top dressings;
• minimum environmental impact;
• convenient packaging - the composition is sold in containers of 0.5 liters.

Appointment of funds

The tool has a wide spectrum of action. It helps to cope with different types of mites - garden spider, citrus silver, hawthorn, red and brown fruit mites. Also, the composition is effective against grape felt and common spider mites.

Consumption rate and instructions for use

This acaricide, when exposed to ticks, provokes their paralysis and reduces egg laying. This is due to the following processes:

• instantaneous paralysis due to nerve impulse;
• complete cessation of all life processes;
• stop the development cycle of the parasite.

The drug has a long protective effect. It persists for 21-28 days. At the same time, the substance does not produce a phytotoxic effect on cultivated plants. The insecticide does not affect entomages. These include predatory mites and beneficial insects such as bees.

In addition, the drug is allowed to be combined with most other substances. The only exceptions are calcium sulfate and Bordeaux liquid. To get the maximum effect, processing should be carried out at elevated temperatures. They should be +25-30 degrees.

The drug can be used once during the season. In this case, first you need to make a working fluid. You need to prepare the composition right before spraying. To do this, the tank should be filled with a third of water. With the mixing device switched on, it is recommended to add the required volume of water to obtain the calculated volume.Then mix and sprinkle the plantings. The working fluid is recommended to be applied on the day of manufacture.

The dosage and rules for the use of the substance are indicated in the table:

Processing time HopSpider mites1,7-2,1500-2000 Spraying bushes is performed when a large number of mites appearSoyaSpider ticks0.7-1.15200-400You can spray plantings before flowering or at the formation stage ovaries

Cultivated plant	Parasites	Consumption rate, liters per 1 hectare	Dose of working fluid, liters per 1 hectare
Grapes	Spider mites	0, 6-0.9	800-1000	Treat shrubs at the stage of mass appearance of ticks.

Protective action lasts at least 3 weeks.To avoid the emergence of resistance to the substance, it must be alternated with insecticidal agents from other categories. Subject to the dosage, the substance does not have a toxic effect on plants. Plants show high tolerance to the substance when used according to the rules of application.

Safety when using

The drug belongs to the third class of danger for bees. This means that it is a low-risk substance. However, when using it, you must adhere to the general safety rules:

1. Don't treat flowering entomophilous plants during the active bee summer.
2. Planting should be processed in the morning and in the evening. In the daytime, spraying is permissible in cloudy and cool weather.
3. Processing should be done with a maximum wind speed of 4-5 meters per second.
4. The size of the border zone for bees should be at least 2-3 kilometers. The duration of the limitation of the summer of bees is 3-4 hours. At the same time, beekeepers need to be informed about the planned treatment at least 4-5 days in advance. They should be aware of the timing and processing zones for landings.

Despite the low toxicity of the substance to humans, the following should be considered:

• apply skin protection products;
• if a substance gets on the body, wash it off with plenty of soap and water;
• do not keep the drug near food;
• do not spray near bodies of water.
