KNOW AND CONTROL CUCUMBER PESTS

MANAGEMENT PRACTICES F0R AVOIDING CUCUMBER PR0BLEMS

Diseases, pests, and disorders remain a threat to efficient cucumber production and good profits by lowering yields, reducing quality, and making harvests unreliable. The risk of these problems can be reduced by wise management.

• Keep records.
• Select adapted cultivars with resistance to downy mildew, powdery mildew, anthracnose, scab, angular leafspot, and cucumber mosaic.
• Practice a 12-month, noncucurbit crop rotation.
• Select fertile, well drained fields.
• Sample fields annually for pH, nutrients, nematodes, soil insects, and weeds.
• Use certified seed treated with fungicides and insecticides.
• Seed 0.5-1.0-inch deep on raised beds after soils warm to 60° F.
• Place one strong colony of bees per acre after blooms are present.
• Apply a general purpose fungicide shortly after emergence and include an insecticide as needed.
• Diagnose all leafspots and plant abnormalities promptly.
• Use a high pressure (250 + psi) sprayer for fungicide and insecticide applications.
• Irrigate fields to ensure 1.0-inch of water each week.
• Monitor migration of the pickleworm and spray as needed.
• Reapply nitrogen and potassium after leaching rains.
• Pick three times a week.
• Avoid injuries during harvesting and handling.
• Use chlorine in all dump, wash, and handling water
