Anthracnose (Cucurbits)

Anthracnose (Cucurbits) Description: Attacks most cucurbits in warm, wet weather. Infected fruit develops circular brown to black sunken areas, up to 1″ across. Overwintering occurs in plant refuse and on seed. Cucumber beetles and splashing water spread spores. Solution: For best control, begin spraying with Soap-Shield® Fungicidal Soap before the disease normally appears (when warm, humid weather is the normal […]

Gray Mold (Tomatoes)

Gray Mold (Tomatoes) Description: Gray mold begins in cool weather. However, unlike many diseases, it doesn’t need high humidity to flourish. Low soil pH encourages more severe gray mold infection. The most characteristic sign of gray mold is its fuzzy, felt-like appearance. Solution: If gray mold has been a problem in past years, begin spraying Soap-Shield® Fungicidal Soap at time […]

Gray Mold (Beans)

Gray Mold (Beans) Description: Gray mold is most common when flowering occurs during a cool period of high humidity. Crowded plants with a dense canopy of leaves also encourage gray mold. Infection begins in the flower and spreads to the pod. . Solution: Rows should be thinned to allow breezes to dry leaves. Avoid overwatering and overfertilizing with nitrogen. Apply […]

Fusarium Wilt (Cucurbits)

Fusarium Wilt (Cucurbits) Description: In young melon, cucumber and watermelon plants: damping-off, stem collapse, and death. In older plants: yellowing, stunting, wilting, and death. The disease is established wherever cucurbits are grown. Solution: Maintain soil pH at 6.5 to 7.0. Test soil pH; if it is too acid, use ground limestone to raise pH. Most garden centers and farm stores […]

Fusarium Root Rot (Peas)

Fusarium Root Rot (Peas) Description: Darkening of stem at soil level, root decline and, as disease progresses, general loss of vigor, stunting, and death of leaves. A serious disease of peas in all areas of the U.S. Solution: Minimize soil compaction and maintain good soil fertility. Alternating with cover crops helps general soil fertility and decreases soil compaction. Sprinkle SoilGardTM […]

Fusarium Wilt on Tomatoes

Fusarium Wilt on Tomatoes Description: The first symptom is yellowing of older leaves, then bright yellowing from top to bottom of plant, often affecting only one branch of plant. Sometimes leaves droop and curve downward. Plants often wilt and die. Solution: Maintain soil pH at 6.5 to 7.0. Test soil pH; if it is too acid, use ground limestone to […]

Fusarium Root Rot (on Beans)

Fusarium Root Rot (on Beans) Description: Slow growth and appearance of red spots or streaks on lower stem and roots. First true leaves prematurely yellow and drop off. Diseased plants often stay alive by producing new roots near the soil surface; however, yield is severely reduced or eliminated. Solution: Minimizing soil compaction is very helpful in reducing fusarium root rot. […]

Fusarium Root and Crown Rot (Tomatoes)

Fusarium Root and Crown Rot (Tomatoes) Description: Entire root system is affected. Brown discoloration is obvious at the base of the stem. Disease progresses slowly from bottom to top, sometimes causing wilting. Disease is widespread in tomato growing regions. Solution: Maintain soil pH at 6.5 to 7.0. Test soil pH; if it is too acid, use ground limestone to raise […]

Fusarium Basal Rot (Onions)

Fusarium Basal Rot (Onions) Description: First seen as curving, yellowing of leaf tips, progessively moving downward. Solution: Do not grow grain cover crops in rotation with onions or garlic. Maintain soil pH at 6.5 to 7.0. Test soil pH; if it is too acid, use ground limestone to raise pH. Most garden centers and farm stores sell ground limestone. Do […]
