Polyhexamethylene guanidine hydrochloride

Polyhexamethylene guanidine hydrochloride (PHMG-HCl) belongs to the guanidine polymer group and is a highly effective, broad-spectrum antiseptic agent.

Its biological activity mechanism is based on the ability to interact with negatively charged components of pathogenic microorganism cell membranes.

Upon contact with the cell surface, the active substance blocks membrane transport systems, leading to metabolic disruption and subsequent pathogen death.

Formulations based on PHMG provide a pronounced long-lasting effect by creating a protective film on the surface of seeds or growing plant parts.

A significant feature is the substance's ability to penetrate plant tissues, ensuring systemic protection against the infectious background over an extended period.

This group of substances is primarily used as a fungicide and bactericide to combat a wide range of phytopathogens, including fungal and bacterial microflora.

The products are effective against agents causing root rots, smut diseases, powdery mildew, late blight, and various types of bacterial diseases in crops.

• Fusarium and Helminthosporium root rots
• Bacterial leaf spot
• Seed molding during storage
• Various types of Alternaria and Septoria blight

Polyhexamethylene guanidine hydrochloride is used for treating planting material of cereals, legumes, vegetables, and industrial crops.

In addition to disease protection, the substance exhibits antiseptic properties, promoting substrate health and preventing secondary infections during the growing season.

Application rates depend on the formulation and the method of administration: for seed treatment, it is calculated per ton of grain, and for spraying, per hectare of area.

During pre-sowing treatment, it is crucial to ensure uniform coverage of the seed surface, which is achieved by thorough mixing of the working solution with the seeds.

Waiting periods before harvest when using PHMG-based products are usually minimal, making them attractive for integrated pest management systems.

To prepare the working solution, use water free from mechanical impurities to avoid reducing the activity of the polymer compound.

It is recommended to carry out seed treatment well in advance of sowing, ensuring sufficient time for the seeds to dry before being placed in drills.

The use of polyhexamethylene guanidine hydrochloride requires strict adherence to safety regulations established for handling chemical pesticides.

The substance is a moderately hazardous compound, so personal protective equipment for skin, respiratory organs, and eyes must be used during operation.

Avoid releasing solutions into bodies of water or drinking water sources, as the compound is highly stable in the aquatic environment.

Mixing PHMG-based products with incompatible pesticides is not recommended without conducting a preliminary chemical compatibility test of the components.

Concentrates should be stored in a cool, dark place, out of the reach of children and animals, in the original tightly sealed manufacturer's packaging.
