The Technology of Precise Application of Herbicides in Onion Field Cultivation

The purpose of the field experiments was to show possible differences in quality and size onion yield amount working liquid used technology precise application herbicides. research material an plantation during three growing seasons 2015/2016, 2016/2017, 2017/2018. Cultivation conditions were same for all plots covered by experiment. Onions grown row-strip method with a spacing 150 cm. experimental factor weed control on plots: A—without weeding (control); B—manual weeding; C—conventional herbicide application; D—precise application. Herbicides used: Agil 100EC, Pendigan 330EC, Roundup 360SL, Galigan 240EC, Goal 480SC, Lontrel 300SL, Emblem 20WP, Fusilade Forte 150EC, Szogun 10EC, Lentagran 45WP. total did not differ statistically within accepted confidence interval, regardless studied. developed allows reduction consumption cultivation 26% compared conventional technology, which is great importance aspect introducing chemical substances into environment their accumulation crops.
