Modern pesticides can address several issues simultaneously: restoring crops damaged by diseases, providing long-term protection against infection, and increasing the quantity and quality of harvests. Using the fungicide "Abacus Ultra" according to the instructions allows for this comprehensive effect after just one treatment.

Composition, release form and what it is used for

The product contains antifungal compounds from different chemical classes: pyraclostrobin and epoxiconazole. The concentration of each active ingredient is 62.5 grams per liter of molding mass. "Abacus" of the "Ultra" series is a suspension concentrate, packaged in 10-liter plastic screw-top containers.

Purpose of the product

This fungicide is intended for the curative and preventative treatment of cereal crops, sugar beets, soybeans, and corn against a number of common and specific diseases. Abacus Ultra is effective against the following plant diseases:

powdery mildew;
various types of rust;
spotting;
septoria;
pyrenophorosis;
Rhynchosporium;
fusarium;
Cercospora leaf spot;
phomosis.

The drug also combats helminthosporiosis and rot.

Modes of action

Thanks to its combined composition, the fungicide "Abacus Ultra" has a multi-level eradicating and protective effect, penetrating plant tissues through systemic and contact routes. Epoxiconazole is a triazole compound with a broad spectrum of antifungal activity. It acts quickly and sustainably, providing protection to crops for up to 6 weeks. Epoxiconazole disrupts metabolic reactions in fungal cells, inhibiting mycelial growth.

This substance controls mitospore formation, prevents the proliferation of fungal agents, and inhibits their key cellular processes. Pyraclostrobin is a member of the strobilurin class with pronounced fungicidal activity and protective properties.

The substance disrupts the cellular respiration of the fungus, spreading over the surface of leaves and plant stems and gradually penetrating into the vascular pathways of plant tissue, and also interferes with energy exchange.

Pyraclostrobin has the ability to stimulate plant life cycles. The additional AgCelence effect of the Abacus Ultra fungicide improves nitrogen absorption by plant tissues, increases plant resistance to stress factors, and supports tissue respiration and photosynthesis.

How to prepare a working solution

To treat crops, it is necessary to prepare a working solution, which is an aqueous dilution of a concentrated emulsion. The required amount of the preparation for a specific crop is diluted in water. The freshly prepared dilution is used for treatment.

The working solution is used topically for spraying the above-ground parts of plants during the growing season. Directions for using Abacus Ultra for treating agricultural crops:

Spring and winter barley	Powdery mildew Rust White and bordered spots	1.0-1.5	300
Spring barley	Powdery mildew Rust White and bordered spots	1.5
Sugar beet	Powdery mildew Fomoz Cercospora spots	1.25-1.75			Not less than 50
Corn	Fusarium Rotten Helminthosporium Bladder smut	1.5-1.75			Not less than 50

For soybeans, the product is used at an average dose of 1.5 liters per hectare. In most cases, a single application is sufficient. Repeated treatment is usually required for beets and corn. Applications can be spaced 2-3 weeks apart.
