I need an organic cure for early blight on my tomatoes.?
Question:I'd rather not use a commercial product on my yummy tomatoes.
Answers:
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.
Kaligreen Potassium Bicarbonate Solubale Powder is an approved organic fungicide. Here is the label for Kaligreen: http://www.montereychemical.com/label/ka...
Warnings: Liquid detergents can be phytotoxic to plant leaves. Always test a few leaves before general use on your plants. Do not apply sulphur in hot (above 80 degrees F), dry weather as it can damage plants. Milk is an effective fungicide for black spot on Roses, but I have never seen milk reported to control early blight in tomatoes.
some soapy water on them or wood ashes
Try sulfur also use a milk and water mix 1 part milk to 10 parts water to prevent blackspot.
I have also heard that some people put a small bit of copper wire pierced at the base of their plant to combat fungal decease
To start with just pinch the infected leaves and dispose of them in to the trash. When the growing season is over get rid of the plants to keep the blight from returning.
