Corn Yield Response to Pyraclostrobin with Foliar Fertilizers

摘要: Strobilurin fungicides, including pyraclostrobin, protect many crops from several fungal pathogens and create opportunities to increase plant health yields. However, corn ( Zea mays L.) other plants’ physiological responses pyraclostrobin include increases in processes that require nutrients. By applying foliar fertilizers, growers can adjust their nutrient-management strategy based on the plant’s reaction pyraclostrobin. Identifying increased nutrient demands meeting them with a fertilizer at time of fungicide application (tasselling) could This study evaluated effects foliar-applied 0.11 kg ha -1 a.i. or without 13 commonly available fertilizers yield, tissue macro- micronutrient concentrations, severity disease, grain quality. Field research occurred three University Missouri centers 2008-2009. One fertilizer, 0-0-30-0, caused up 20% crop injury. Diseases affected plants all six site-years, but overall was low (≤ 2%) likely did not impact performance. Pyraclostrobin ear leaf B Cu concentrations over site-years seven days after treatment, decreased N one site-year. Grain yields 5% two sites location had moisture oil harvest. 30-0-0-0, by 10% compared non-treated control. showed no observable quality characteristics, none negatively impacted yield.
