Applying liquid nitrogen through different nozzles, with and without fungicide

Full description

The aim of this trial was to assess any damage to the top four leaves of the wheat crop canopy (as a percentage of leaf area affected [LAA]) seven days after treatment application at second node (GS32) and booting (GS43) stages with different forms of nitrogen. The specific objectives were to:
• assess the phytotoxicity (scorch) of liquid Easy N versus solid urea at GS32 and GS43
• compare the impact of applying liquid Easy N through streaming nozzles and flat fan spray jets
• assess the impact of co-applying emulsifiable concentrate (EC) or suspension concentrate (SC) formulations of foliar fungicides with liquid Easy N
• examine the influence of water rate on scorch at both application timings.
