Na Laboratorijskem polju Biotehniške fakultete v Ljubljani smo leta 2016 izvedli poskus, v katerem smo preučevali delovanje okoljsko sprejemljivih snovi proti koloradskemu hrošču (Leptinotarsa decemlineata), strunam (Agriotes spp.), črni listne pegavosti krompirja (Alternaria solani) in krompirjevi plesni (Phytophthora infestans) na krompirju, sorte 'Natascha'. Te okoljsko sprejemljive snovi so bili pripravki Mineral zeleni, Mineral rumeni in Mineral rdeči. Preučevali smo vpliv kombinirane uporabe zmanjšanih odmerkov fitofarmacevtskih sredstev in pripravkov Mineral na različne razvojne stadije koloradskega hrošča, na stopnjo okužbe listov krompirja s črno listno pegavostjo krompirja in krompirjevo plesnijo, kako se na navedeno strategijo zatiranja odzovejo strune in kako navedene snovi vplivajo na pridelek gomoljev. Največji pridelek gomoljev (14,34 t/ha) smo ugotovili v obravnavanju s samostojno uporabo FFS, najmanjši pridelek pa na parcelah, kjer nismo škropili (8,6 t/ha). Pridelek v obeh obravnavanjih s pripravki Mineral je bil med navedenima vrednostma, in sicer 12,8 t/ha na parcelah s kombinirano uporabo pripravkov Mineral in zmanjšanih odmerkov FFS ter 9,7 t/ha na parcelah, na katerih smo uporabili le pripravke Mineral. Z rezultati raziskave smo potrdili hipotezo, da je mogoče s sočasno uporabo reduciranih odmerkov fitofarmacevtskih sredstev in pripravkov Mineral zmanjšati številčnost preučevanih škodljivcev in obseg bolezni ter omogočiti zadovoljivo zdrav in visok pridelek krompirja.

Testing the efficacy of simultaneous use of reduced doses of plant protection products and preperations mineral in controlling harmful organisms on potato (Solanum tuberosum L.) |
Sekundarni povzetek: |
In 2016 we tested the activity of environmentally friendly substances against the Colorado potato beetle (Leptinotarsa decemlineata), wireworms (Agriotes spp.), early blight of potato (Alternaria solani), and late blight of potato (Phytophthora infestans) in potato field (variety 'Natascha') at the Laboratory Field of Biotechnical Faculty in Ljubljana. Environmentally friendly substances tested were the products Mineral green, Mineral yellow, and Mineral red. We investigated the impact of simultaneous use of reduced doses of plant protection products and products Mineral on different developmental stages of Colorado potato beetle, on extent of leaf infection of potato caused by early blight and late blight, yield of potato tubers, and the response of wireworms on mentioned strategy of potato protection. The highest yield of potato tubers (14.3 t/ha) was confirmed in the treatment with the use of plant protection products, while the lowest yield was established in control treatment (8.6 t/ha). The yield in both treatments with the products Mineral (single use [9.7 t/ha] and the simultaneous use with the reduced doses of plant protection products [12.8 t/ha]) were between mentioned yields. With the results of our research we confirmed the hypothesis that the simultaneous use of reduced doses of plant protection products and products Mineral enable the occurrence of investigated pests and diseases in lower extent, and satisfactory healthy and high yield of potato tubers. |
