Nerolidol

Nerolidol (3,7,11-trimethyl-1,6,10-dodecatrien-3-ol) belongs to the class of terpenoid alcohols. It is a sesquiterpene found widely in nature, serving as a primary component of essential oils in various plants, including neroli, ginger, and lavender. In agronomy, this substance is valued primarily as a semiochemical capable of influencing the behavior of arthropods.

The main purpose of nerolidol in plant protection is its role as an attractant or repellent in pheromone traps. It mimics natural signaling substances that attract specific insect pests to monitoring sites or traps. Additionally, the substance can exhibit fumigant activity and provide moderate contact effects against certain species of mites and small insects.

The mechanism of action for nerolidol is based on its chemoreceptive impact on the nervous system of pests. When used in traps, it disrupts the orientation of insects or mimics an odor trail that attracts male individuals, allowing for effective monitoring of population levels and the implementation of timely protective measures.

The product is utilized in fruit growing, viticulture, and greenhouse vegetable production to control spider mites, thrips, and certain species of Lepidoptera. The use of nerolidol allows for a reduction in the pesticide load on the agroecosystem, as it often replaces or complements traditional chemical insecticides in integrated pest management programs.

When working with this substance, standard safety precautions must be observed despite its natural origin. Direct contact with the skin and mucous membranes should be avoided, and personal protective equipment must be used. Concentrated forms should be stored in a cool, dark place, as the substance is sensitive to oxidation and ultraviolet radiation.
