Effects of bagging treatment on fruit quality and pesticide residues of ‘Donghong’ kiwifruit

In this study, the effects of bagging treatment on fruit appearance and internal quality, including shape index, single weight, vitamin C, soluble solids, titratable acid, chlorophyll carotenoid content, were studied by using ‘Donghong’ kiwifruit as experimental material. Meanwhile, pesticide residues bagged non-bagged (NB) compared analyzed. Results showed that pericarp color is lighter in green than NB group, with uniform color, cleaner no scabs spots. Single weight transverse meridians kiwifruits significantly increased. Interestingly, we found had little effect quality kiwifruit. After treatment, was rounder, increased content fruit, decreased C carotenoids. addition, + additive these characters. bagging, pyraclostrobin β-cypermethrin lower those control. However, residue difenoconazole did not show significant difference. Bagging has ability to improve reduce some pesticides. application pesticides can quality. Therefore, a scientific effective cultivation method production
