With population buildup during hot, dry periods, fine webbing may be observed. Same as for soybean thrips. Foliar feeding by loopers can strip leaves and delay growth of small plants in late plantings. Check traps for this migrating insect, scout fields and spray when young larvae are seen. Place one bee colony per acre after flowering, fertilize according to soil test reports, and irrigate.
Honey bees are essential for successful cucumber pollination and production.
At least one strong colony per acre is needed to ensure adequate bee activity. Colonies should be placed in the field after the onset of significant flowering. All cucurbits are susceptible, and depending on the weather, stem and leafspotting may occur on young plants, especially in late plantings. Anthracnose is common and is caused by the seedborne fungus Colletotrichum lagenarium. Most cucurbits are susceptible.
