Disease management program • Basic proactive program – Regalia – Actinovate AG – Stimplex – 5 day interval • Downy mildew pressure had us use Tanos or Curzate or Ranman • Early crop had a single bout with PM – Single application of Torino fixed that • As cuke plants age, PM challenges increase
  20. 20. Insect and mite management • Removal of cucumber beetles simplifies entire pest management program. • Mites, Aphids and Thrips: – Weekly preventative: • Grandevo • MET52 • M-Pede at 3%
