Abstract

Some modern agrochemicals with antioxidant potential were tested for their protective effect against ozone injury using clover and tobacco ozone-sensitive cultivars as model plants subjected to ambient ozone at two sites (Kyiv city in Ukraine and Szarów village in Poland). All used agrochemicals showed partial protective effects against ozone injury on clover and tobacco. Conducted studies confirmed the effectiveness of modern fungicides belonging to strobilurin group as protectants of sensitive crops against ozone damage. The effectiveness of new growth regulators “Emistym C” and “Agrostymulin” was showed for the first time. Out of the studied agrochemicals, fungicide “Strobi” and natural growth regulator “Emistym C” demonstrated the best protective effects. These agrochemicals present promise for further studies of their possible utilization for enhancement of ozone tolerance of sensitive crops.

Summary

Introduction

Ozone is one of the major toxic to vegetation and human health gaseous air pollutants. It contributes to crop losses and forest decline. It was estimated that the present day global relative yield losses range between 7% and 12% for wheat, between 6% and 16% for soybean, between 3% and 4% for rice, and between 3% and 5% for maize (range resulting from different metrics used) [1]. For the year 2000 global crop yield loss due to ambient ozone was estimated to be worth $14–26 billion. Crop yield loss due to ambient ozone in the U.S.A. was estimated to be worth $3–5 billion annually [2]
