Paprika extract

Paprika extract, containing the carotenoids capsanthin and capsorubin (known as food additive E160c), is an active ingredient of natural origin used in modern plant protection strategies. While primarily known for its coloring properties in food, in agronomy, it serves as a bioactive compound that aids in managing insect populations through non-toxic, behavioral-modifying mechanisms.

The mechanism of action involves the modification of host plant surface characteristics, which affects the behavior of pests. By altering the visual and chemical cues that insects use to identify their host, the extract disrupts their settling and feeding processes. This acts as a deterrent, preventing heavy colonization by pests without causing mortality through direct chemical poisoning.

The product is utilized on a variety of crops, including vegetables, fruits, and ornamentals, to manage populations of aphids, whiteflies, and mites. It is particularly valued in greenhouse environments where strict control over chemical residues is necessary, providing a sustainable way to suppress pest pressure during the growing season.

Application techniques require careful attention to coverage and timing. Because carotenoids are sensitive to ultraviolet light, applications are recommended during low-light conditions, such as late afternoon or evening. This practice ensures that the substance remains active on the foliage for a longer duration, maximizing the repellent effect.

Safety precautions for handling paprika extract are minimal compared to synthetic pesticides. It is classified as a low-risk substance, safe for the operator and the environment. Nevertheless, standard precautions such as using protective gloves and goggles when handling the concentrate are recommended to prevent irritation, and the substance is widely accepted in organic farming programs.
