Industrial oil I-20A

Industrial oil I-20A is used in agriculture as a mineral oil of petroleum origin, acting as a surfactant or a direct contact agent. It lacks systemic activity and operates exclusively on the plant surface.

The mechanism of action relies on the physical properties of the oil. Upon application, it forms a thin film over insects and mites, effectively blocking their spiracles (breathing pores). This leads to rapid death through asphyxiation.

In tank mixes, I-20A serves as an adjuvant that improves wetting and adhesion. It prevents the premature evaporation of spray droplets, ensuring that pesticides remain on the target surface for a longer duration.

The oil is capable of dissolving waxy protective cuticles on both insects and plant leaves. This action increases the permeability of the plant surface, allowing systemic active ingredients to penetrate more efficiently.

The product exhibits high chemical stability within aqueous emulsions. It is essential to use high-quality emulsifying agents to ensure a homogeneous distribution of oil particles throughout the spray solution.

It is primarily used for controlling overwintering pest stages on fruit trees, such as scales, soft scales, and mite eggs. The oil film effectively suffocates dormant stages hidden in bark cracks.

The substance is effective against various sap-sucking pests during the growing season, including mealybugs and whiteflies. Its ability to penetrate into micro-crevices provides excellent coverage against concealed individuals.

It is widely utilized as a tank-mix additive to enhance the performance of systemic fungicides and insecticides. It is particularly useful for crops with pubescent leaves that are otherwise difficult to wet with water-based sprays.

• Scale insects and soft scales
• Spider mites and gall mites
• Insect egg clusters
• Whiteflies

Application rates vary depending on the growth stage of the crop. For early spring treatments during the dormant phase, concentrations up to 2-3% are commonly used.

During the vegetative period, the concentration is reduced to 0.5–1% to avoid potential phytotoxicity. Precise calculation and proper emulsification are critical to avoid crop damage.

Treatments should be applied during cool morning or evening hours, ideally at temperatures below +25°C. Excessive heat can cause the oil film to overheat leaf tissues, leading to necrosis or physiological stress.

Applications during the flowering period are strictly prohibited to protect pollinators. The oil film can coat flower parts, significantly disrupting their function and harming beneficial insect populations.

Mixing with sulfur-based products must be avoided at all costs, as this combination is highly phytotoxic and can cause severe chemical burns to plants. A waiting period of at least two weeks between these treatments is mandatory.
