Pesticides are chemicals that are widely used in agriculture. They have several benefits, such as
controlling harmful organisms and weeds that destroy crops and threaten people’s lives. They also
help farmers increase crop yields to provide enough food resources for a growing population, decrease
food costs, and prevent sickness caused by moldy food. But there is a thin line between positive and
negative effects of pesticide use. Therefore, after the treatment of plants with pesticides, it is
necessary to monitor their stability in the environment. If the plants do not absorb pesticide, it reaches
the surface and groundwater. This research aimed to assess the positive effects and solar stability of
commercial pesticides Ormoroc and Globaryll used to treat grapevine and fruits. Ormoroc and
Globaryll increased fruit weight, diameter and fruit firmness of sour (cv. Erdi botermo) and sweet
(cv. Regina) cherries. The stability of Ormoroc and Globaryll was monitored at room temperature in
the dark. Under these conditions, they were highly stable. The more significant investigation for the
environment is the solar stability of these pesticides. Our results indicate the decomposition of the
mentioned compounds under UV radiation. As UV light is a part of solar radiation, these results
suggest that applying investigated formulations and their degradation using solar radiation is one of
the foundations of sustainable agriculture.
