Abstract

This article explores the issues of reducing chemical loads and "ecologizing" protection systems to safeguard natural populations of Sea Buckthorn (Hippophae rhamnoides L.) from major pests within the Zarafshan National Nature Garden. Drawing on established expertise from Russia’s Siberian region, the research analyzes the effectiveness of using a biologically active additive (BAA) based on organic acids, the natural compound-derived preparation "Afidin," and the bio-based pesticide "Fitoverm." The findings reveal that the application of the BAA allows for a reduction in the consumption rates of "Fitoverm" and "Actellic" by 2 to 2.5 times without compromising their entomological efficacy. For the ecosystem of the national park—a protected area—this method is highly significant, as it reduces toxic residues in the fruit by 2.2 to 4 times, ensuring the cultivation of entirely ecologically safe products. Under the arid and hot climate conditions of the Zarafshan oasis, this approach enhances the plants' stress resistance, contributing to a yield increase of 138–150%. In pest control trials, "Actellic" demonstrated a 95.8–100% efficacy against the sea buckthorn fly and flea beetle, while "Fitoverm" showed 98.9–100% effectiveness against mites. Furthermore, the preparation "Afidin" is recommended as an effective agent specifically against the green sea buckthorn aphid (Capitophorus hippophaes), which is widely distributed throughout the Zarafshan oasis.
