Garlic extract

Garlic extract is a class of natural, plant-based biopesticides. The primary active component is allicin, a sulfur-containing compound that exhibits high biological activity against a wide range of pathogens.

The mode of action involves disrupting metabolic processes in insects and fungal microorganisms. Allicin inhibits the enzymatic activity of pests, leading to their suppression and eventual mortality.

Products based on garlic extract act primarily through contact and systemic effects, providing a strong repellent action. They create a protective barrier that makes plants unattractive to phytophagous insects.

Unlike synthetic pesticides, this substance degrades rapidly in the environment without accumulating in fruits or soil, making it an ideal tool for integrated pest management and organic farming.

The antimicrobial properties of the extract are due to the ability of phytoncides to suppress the respiratory processes of pathogenic fungi and bacteria, preventing the development of infection outbreaks.

This group of substances is effectively used to control sucking pests such as aphids, thrips, spider mites, and whiteflies. Activity against certain larval stages of lepidopterans has also been reported.

In terms of fungicidal action, the extract is used to prevent the development of powdery mildew, gray mold, various leaf spots, and bacterial diseases on vegetable and ornamental crops.

• Spider mites
• Thrips
• Whiteflies
• Powdery mildew

Applying garlic extract requires regularity, as the product provides mainly prophylactic and suppressive action. It is recommended to begin treatments before the mass emergence of pests.

The interval between treatments during the vegetation period typically ranges from 7 to 14 days, depending on the infection pressure or the population density of the insects.

The application rate depends on the crop type and plant growth stage. It is important to ensure uniform coverage of the leaf surface, including the undersides where pests often congregate.

To maximize efficacy, it is recommended to add a spreader-sticker (adjuvant) to the solution to improve the adhesion of active substances to plant tissues.

Application rates vary depending on the concentration of the active ingredient in specific formulations, so always follow the manufacturer's instructions carefully.

A primary limitation is the dependence of product efficacy on weather conditions. Heavy rainfall washes the active components off the leaf surface quickly.

Garlic extract does not have high persistence, so its application is not recommended during epiphytotics or severe pest outbreaks that require an immediate knockdown effect.

When using, consider the specific odor, which may persist on crops for several days, which is important when treating leafy greens close to harvest time.

The product is compatible with most biological control agents, but compatibility tests should be conducted before mixing with synthetic chemical pesticides.

Standard safety precautions should be followed during application, including the use of personal protective equipment for skin and respiratory protection, despite the organic origin of the substance.
