FLOWERING: PROTECTING YIELD POTENTIAL

  • In general, the highest risk of pest and disease attacks occurs around flowering time
  • Diseases: Sclerotinia is one of the most harmful diseases for oilseed rape. Favourable conditions for sclerotinia are humidity of more than 90% for over 3 days at the flowering stage and an average daily temperature of under 12°C. Ventilated vegetation and adapted density limit the risk. If necessary, fungicide treatment should be administered during the G1 stage, first leaf fall or 6-10 days after flowering
  • Pest control: It is important to survey pests, especially pollen beetle which can seriously affect yield potential (abortion and bud reduction)
