On tomato and eggplant, blossom-end rot usually begins as a small water-soaked area at the blossom end of the fruit (Figure 1). This may appear while the fruit is green or during ripening. As the lesion develops, it enlarges, becomes sunken and turns black and leathery. In severe cases, it may completely cover the lower half of the fruit, becoming flat or concave Blossom-end rot is not caused by a parasitic organism but is a physiologic disorder associated with a low concentration of calcium in |

Disease fungi (Fusarium oxysporum) enter through the roots and interfere with the water conducting vessels of the plant. As the infection spreads up into the stems and leaves it restricts water flow, causing the foliage to wilt and turn yellow. Symptoms often appear later in the growing season and are first noticed on the lower (older) leaves. As the disease progresses, the younger leaves will also be affected and the plant eventually dies. In many cases, only one branch or side of the plant sho |

My yellow straight neck squash plant has been healthy and producing. Today when I examined my garden this plant was wilted and curled with these huge ugly fungus growths all over the base of the plant. I do not know what this is or where it came from, I planted this garden 8 weeks ago and have had no problems. |

Clubroot is a common disease of cabbages, radishes, turnips and other plants belonging to the family Cruciferae (mustard family). It is caused by Plasmodiophora brassicae, which was once considered a slime mold but is now put in the group Phytomyxea. It has as many as nine races. Gall formation or distortion takes place on latent roots and gives the shape of a club or spindle. In the cabbage such attacks on the roots cause undeveloped heads or a failure to head at all, followed often by decline |
