Is there anything I can do about tomato blight.?
Question:
Answers:
Early blight is a disease of warm, wet weather. Late blight is a disease of cool weather. It's more likely that you have early blight considering our current weather patterns.
Cultural controls of early blight include: 1) Use only clean seed saved from disease-free plants. 2) Remove and destroy crop residue at the end of the season. Where this is not practical, plow residue into the soil to promote breakdown by soil microorganisms and to physically remove the spore source from the soil surface. 3) Practice crop rotation to non-susceptible crops (3 years). Be sure to control volunteers and susceptible weeds. 4) Promote good air circulation by proper spacing of plants. 5) Orient rows in the direction of prevailing winds, avoid shaded areas, and avoid wind barriers. 6) Irrigate early in the day to promote rapid drying of foliage. 7) Healthy plants with adequate nutrition are less susceptible to the disease. 8) Minimize plant injury and the spread of spores by controlling insect feeding. 9) Hand picking diseased foliage may slow the rate of disease spread but should not be relied on for control. Do not work in a wet garden. 10) Use resistant or tolerant varieties.
Potassium bicarbonate is an organic fungicide legally labeled for disease control purposes and can be used for powerdy mildew control on cucurbits, roses and grapes as well as EARLY BLIGHT control on cucumber and tomato. Trade names include Kaligreen, Amicarb, First Step and Remedy.

Trim off each and every leaf and stem that does not have a bloom or fruit by now. You'll increase air circulation and not promote fungal infections. You will basically peel that stem bare, except for where it is productive.
Then stalk the plant.
