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
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%
Pest management by backpack
