Description
Summary:Pests of mandarin reduce significantly crop productivity and commercial quality of the crop in Abkhazia. We assessed the impact of optimized mandarin pest control schemes on fruit size and crop yield in the humid subtropics of Abkhazia. The studies were carried out in 2019-2020 on full-aged plantings of cv. Unshiu mandarin in Gulrypsh district of Republic of Abkhazia on the base of Institute of agriculture of Academy of sciences of Abkhazia. The highest yield and quality of fruits was shown by the protection schemes in variants 5 (Confidor extra (0.05 %) + Cytovit (0.15 %) – the 1st treatment Vertimec (0.1%) + Cytovit (0.15 %) – the second treatment; the third and fourth treatments Karate Zeon (0.05 %) + Cytovit (0.15 %)) and 6 (Metomax (0.15 %) + Vertimec (0.1 %) – the 1st treatment; Karate Zeon (0.05 %) + Vertimec (0.1 %) in the other three treatments). The average fruits weight in these variants was up to 72-74 g. This exceeded the fruits weight in the Standard variant by 22.0-25.4 %. The yield was 46.2-44.7 t/ha, which is 36.8-41.3 % higher than the standard variant. Fruits of the 1st grade in the named variants accounted for 63.3-65.6 % of the total yield.
