Abstract
Pioneering results of seed-potato health improvement and the suppression of soil-borne infection during the potato production by the preplant coating of tubers with an azoxystrobin-loaded degradable polymer film coating are presented. The film coating was applied to the surface of potato tubers by spraying with a 1% solution of the degradable polymer poly(3-hydroxybutyrate) in dichloromethane mixed with azoxystrobin. The film coating did not damage the tubers or reduce germination. The half-life of the polymer coating in field soil was 25 days. The film degraded gradually from potato planting to the beginning of flowering, ensuring long-term delivery of the fungicide to the plants. In the experimental group, a more effective reduction in the total number of rhizospheric soil fungi, including plant pathogens Alternaria alternata and Fusarium oxysporum, was revealed, compared with the preplant treatment of tubers with the commercial fungicide azoxystrobin (comparison group). The healing effect of the fungicide-loaded coating led to an improvement in the quality of the potato crop. In the experimental group, the total yield and the share of marketable tubers exceeded those of the comparison group by 5.6 t/ha and 8%, respectively. The proportion of Fusarium infected tubers was 8.5% in the experimental group versus 12.1% in the comparison group. The fungicidal effect of a long-term degradable polymer film coating with azoxystrobin was more successful than traditional treatment of tubers with a solution of this fungicide. Thus, the proposed approach is promising for the protection of seed potatoes.
期刊介绍：
The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
