FONSECA DE SOUZA, Matheus et al. Effect of triadimenol on the development of bean (Phaseolus vulgaris L.) and soil microbial activity. Idesia [online]. 2011, vol.29, n.2, pp.105-110. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292011000200014.

ABSTRACT Triadimenol is a systemic fungicide which belongs to the group of triazoles, used mainly for the control of several diseases of plants.  The present work aimed to evaluate the effect of triadimenol in the culture of beans. The experimental design was completely randomized; using 6 treatments with 4 replicates and 2 pots per replicate. The treatments were: T1= 0.527g of baysiston®. (170 Kg/ha); T2= 0.124g of baysiston® (40 Kg/ha) T3= control; T4= 0.155g of baysiston® (50 Kg/ha); T5= 0.217g of baysiston (70 Kg/ha) and T6= 0.186 g of baysiston® (60 Kg/ha). For most of the characteristics evaluated the control T3 was statistically superior to other treatments. For soil microbial activity, the average hydrolysis of FDA in all treatments was 244.926 µg of FDA hydrolyzed hour-1 g-1 of soil.  Although the test has been shown to be effective, no significant difference was observed between treatments.
