Seed Treatment

Use thiram 75Wp at 3 to 4 ounces per 100 pounds (2/3 teaspoon per pound) plus Apron XL LS (0.32 to 0.64 fluid ounce) per 100 pounds of seed for improved germination and stand.

Disease Control

Damping-Off
Use seed treated with thiram plus Apron XL LS (0.32 to 0.64 fluid ounce) per 100 pounds of seed.

Seedling Rot and Basal Stem Rot
azoxystrobin (Quadris at 0.4-0.8 fl oz 2.08F/1000 ft of row or Amistar at 0.125-0.25 fl oz 80WDG/1000 ft of row.

Fusarium and Verticillium Wilts
Avoid planting in fields where either disease is present. Rotate with non-solanaceous crops. Disease control rates of soil fumigants will aid in control of Verticillium wilt.

Fruit Rot
Choanephora attacks senescent blossoms and grows into the fruit. No fungicide is labeled for control. To assist in control, avoid practices which restrict air movement. Improving air circulation is the only effective control of this disease. In extreme cases, growers sometimes remove the lower juvenile leaves to improve air circulation.
