Application of Strobilurins and Carboxamides Improves the Physiology and Productivity of Tomato Plants in a Protected Environment

The use of fungicides from the strobilurin and carboxamide groups demonstrates an effect on photosynthetic efficiency by increasing CO2 assimilation and, consequently, plant productivity, due to better a physiological performance. objective was evaluate application these physiology yield tomato plants. A randomized block design used with six treatments five blocks: control, azoxystrobin (75 g ha−1), boscalid pyraclostrobin fluxapyroxad ha−1) + (50.1 99.9 ha−1). Different physiological, biochemical antioxidant enzymatic parameters were evaluated. increased 64% production per 91%. activity nitrate reductase enzyme 1.69 times, system 3.68 times pigments 1.16 under action studied respect control. Therefore, favored development plant, especially Pyraclostrobin
