Yonca y\u00f6netiminde en kritik zamanlama karar\u0131, kurtarma bi\u00e7imi yapmak m\u0131 yoksa b\u00f6cek ilac\u0131 uygulamak m\u0131 gerekti\u011fidir. Bu karar, d\u00f6rt de\u011fi\u015fkenin ayn\u0131 anda de\u011ferlendirilmesini gerektirir: normal bi\u00e7ime kalan g\u00fcn say\u0131s\u0131, larva say\u0131s\u0131 ve hasar \u015fiddeti, hava tahmini ve saman pazar\u0131n\u0131n zamanlamas\u0131. D\u00f6rt de\u011fi\u015fkenin de erken bi\u00e7im i\u00e7in uygun olmas\u0131 durumunda, bu neredeyse her zaman do\u011fru se\u00e7imdir. Uygun olmamalar\u0131 durumunda ise, ila\u00e7lama se\u00e7ene\u011fi normal zamanlamada bi\u00e7im yapma se\u00e7ene\u011fini korur.<\/p>\n
