Kartoplex 100 g

Kartoplex, 100 g – a comprehensive stimulant for treating potato planting material and vegetable seedlings.

Acts in two ways simultaneously:

• protects the plant from soil pests

• stimulates root development and overall plant growth

The complex of microorganisms included in the formulation is capable of endophytic colonization of the surface of the potato root system.

• The Bacillus azotofixans microorganism culture has high nitrogen-fixing activity (the ability to bind atmospheric nitrogen), which provides additional nitrogen to potato plants

• Bacillus megaterium microorganisms, through the production of a complex of organic acids (citric and malic acids) and enzymes (phosphatases), are capable of breaking down hard-to-access phosphorus and potassium compounds, which are present in significant quantities in the soil, thereby improving phosphorus and potassium nutrition in potato plants.

• Active colonization of the root system by the microorganism-producers in the preparation helps protect plants from a range of root rots of fungal and bacterial origin.

• Colonization of plant tissues and the synthesis of physiologically active substances (salicylic and jasmonic acids) boost plant immunity and reduce susceptibility to a range of leaf and stem diseases.

• The soil fungi Beauveria bassiana and Metarhizium robertsii, which are components of the preparation, possess high entomopathogenic activity.

• Upon contact with the pest’s cuticle, fungal spores germinate and penetrate the pest’s body; the fungal mycelium infects adipose tissue, the intestinal tract, and nervous tissue, leading to the pest’s paralysis and death. Furthermore, the dead pest serves as a source of infection for other pests, prolonging the product’s overall effectiveness!

These microorganisms are active producers of the main complex of phytohormones that stimulate plant growth:

• Auxins—promote the formation of a robust root system, improve plant development, and increase the total root surface area, leading to better absorption of nutrients (nitrogen, phosphorus, potassium, etc.) and moisture from the soil.

• Gibberellins—secreted by fungi, they help increase the photosynthetic surface area and activate chlorophyll synthesis, which positively affects plant productivity.

• Cytokinins—produced by microorganisms, increase the intensity of photosynthesis, regulate the supply of nutrients to plant cells, and provide protection against adverse environmental factors

Importantly, thanks to the presence of microorganisms in the root zone, the plant is supplied with stimulating substances throughout the entire growing season (unlike chemical stimulants)!!!

Composition

Mycelium and spores of the endophytic fungi Beauveria bassiana, Metarhizium robertsii, and beneficial soil bacteria Bacillus megaterium, Bacillus azotofixans with a titer of at least 1.5 × 10⁹ cells/g, and their metabolic products (phytohormones, complex of organic substances). 

Formulation:

Water-soluble powder

Application methods and doses

Tubers can be treated in two ways:

Prepare the working solution 1–2 hours before treatment.

1. By spraying: evenly spread potato tubers are sprayed using a backpack or hand sprayer. Treatment can also be carried out using industrial seed treatment units, provided the recommended application rates for the product and working fluid are followed. Before filling the sprayer tank with the working solution, it must be filtered through a mesh filter or two layers of gauze!!!

2. Soaking method: Pour the prepared working solution into a suitable container. To treat the tubers, completely submerge the mesh bag containing the planting material in the container for 2–3 minutes. Afterward, allow the treated potato tubers to dry for 30–40 minutes.

Processing and storage of treated tubers must be carried out in areas protected from direct sunlight!!!

According to experiments conducted by the Ukrainian Institute of Potato Growing in 2019–2021:

• the overall increase in potato yield was 25–30%

• a 2–3-fold reduction in damage from diseases and pests

Storage conditions:

Store at temperatures ranging from -50⁰°C to +25⁰°C, in a dry place protected from direct sunlight.
