Abstract
The study assessing biochemical components (sugars and organic acids) in mandarin fruits after pest control was carried out in matured plantings of cv. Unshiu mandarin in the Republic of Abkhazia in 2019-2020. The treated fruits contained a greater amount of soluble carbohydrates than the fruits in control. The predominant form of monosaccharides is fructose (17.78-17.85 g/l, with 11.89 g/l in the control) in the fruits from the standard treatment and in variant 6 (with a combination of Metamax, Vermitek and Karate Zeon), which is preferable, since it has the greatest sweetness (173 units), providing a sweeter taste of the fruit. According to the content of organic acids, variants 6 and 8 (four treatments with Diatomite, 6%) were distinguished, the content of citric acid on which was 11.86-11.3 mg/l. A more balanced taste of the fruit was in variants 6, 7 (four treatments with Diatomite, 3%) and 8 (sugar-acid index from 7.7 to 7.9 units). Taking into account the content of basic acids and sugars in mandarin fruits, it is possible to predict the impact of insecticides and their combinations on their basic taste properties.
