L. do  aPhytosanitary risks and agronomic performance of soybeans associated with spatial arrangements of plants.h[electronic resource]  c2019  aAbstract: Soybeans sowing in different plants? spatial distribution can influence the phytosanitary management of this crop and, consequently, impact on grains yield. This study was carried out to evaluate the effect of plants arrangements on infestation and control of caterpillars, the deposition of spray syrup as well as assess the agronomic performance of soybean cultivated in the Brazilian Cerrado. The assay was performed during two consecutive seasons in a randomized complete block design with four replications. Soybean cultivation was implemented in 0.50 m spacing between rows, crossed (0.50 m x 0.50 m), twin rows (0.25 m / 0.75 m), and narrow (0.25 m). In the reproductive stage of plants, both crossed and narrow arrangements showed higher caterpillars? incidence. There was a more evident risk of caterpillar incidence in arrangements that promoted better equidistance among plants. This risk was mitigated when taking into account both control and overlap of syrup, which could be incremented into inferior canopy with the enhancement of application rate. The increase in application rate from 75 to 150 L ha-1 promoted superior spray deposition volumes. Increases in grain yield was noted in the narrow arrangement.  aApplication technology  aFoliar spraying  aPhenotypic plasticity  aSowing  aSoybeans  aYield components  aEspaçamento  aGlycine max  aPulverização  aSoja  aCo  aSowing systems1 aSILVA, A.
