FUNGICIDES, BIOPREPARATIONS AND GROWTH REGULATORS IMPACT ON SPORT LAWNS CONTAMINATION AND QUALITY

Abstract

The work was carried out as part of multi-year research on the effectiveness of fungicides and agrochemicals with various active ingredients on sports turf in different regions of Russia. The results of comparing the effectiveness of fungicides and their mixtures against a complex of fungal diseases in 2019 on a football pitch in Sochi are presented. We compared the following fungicides and their mixtures: Vitaplan (strains of Bacillus subtilis); Super Humisol (humic compounds, phytohormones, macro-, microelements); TMTD-plus (thiram, immunomodulators) + Siliplant (silicа-containing organic fertilizer); TMTD-plus; Falcon (spiroxamine + tebuconazole + triadimenol); Quadris (azoxystrobin) + Siliplant; Quadris (azoxystrobin) - standard, control - water treatment. It found that all agrochemicals to varying degrees reduced the development of plant diseases compared with the control. The lowest rates of development of plant diseases noted after the use of the Quadrice + Siliplant tank mixture. The maximum biological effectiveness was observed in a mixture of Quadris fungicide with Siliplant (44.3%) and Super Humisol (42.6%), TMTD-plus (32.8%) was slightly lower. A comprehensive assessment of the quality of turf grass was carried out at the stadium in 2018-2019, which showed that the results of hardness at the beginning of the game season were within acceptable values, and at the end they decreased due to soil compaction and mechanical damage to plants. According to the NTEP grading scale, the best effect on plant growth and development was identified after treatment with a mixture of Quadris and Siliplant.
