  4. 4. cropprotectionSulfosulfuron EMEA• Sulfosulfuron is a selective herbicide for postemergence control of weeds in wheat and triticale.• It can be applied up to 2‐node stage of wheat• Sulfosulfuron controls major cereal grass species, and some dicots – Apera spica‐venti – Bromus spp. – Elymus repens – Avena fatua – Volunteer barley• The uses rates range from 10 – 20 g a.i./ha• Non ionic surfactant should be mixed to the product 4

  42. 42. cropprotectionSummary EMEA• Sulfosulfuron controls well the important grass weeds harmful in Central‐East Europe in winter wheat• Several mixture partners can be used to broaden activity against dicots• Good agricultural practice should be followed to prevent resistance development 42
  43. 43. cropprotectionGAP recommendation to EMEAprevent resistance• In monoculture rotate mode of action• Under unfavorable conditions avoid antagonizing mixture partners or use sequential application (7‐10 days interval)• Use the recommended rate at right timing to actively growing weeds• Always add surfactant• Calibrate sprayer for accurate dosing• Avoid application at very low temperature or frost• In oil seed rape control grasses 43
