Statice Diseases - Articles


Anthracnose and Crown RotYoung plants wilt, yellow and die. Tan to brown spots with yellow halos develop on flower stalks, wings, and flower parts. These enlarge, become reddish brown to brown or black on some cultivars.Colletotrichum gloeosporiodesApply a fungicide to protect plants.
Bacterial RotYellow and dead leaves are found among healthy basal rosette leaves. Symptoms sometimes develop only on one side of the mid-vein. Veins may be red. Crowns and entire plant die. Rotting crowns smell foul.PseudomonasPlant disease-free seedlings.
Botrytis BlightLeaves on seedlings die and become covered with gray mold. Flowers discolor and collapse. When dried, infected flowers fall out of the head. Entire flower stalk may yellow and die.Botrytis cinereaPurchase decorticated seed that has been treated with hot water and fungicide. Avoid overhead irrigation. Water early in the day so that leaf surfaces dry. Space rows and maintain good weed control to insure adequate air circulation. Apply a fungicide to protect plants.
Cercospora BlightSmall reddish spots form on leaves and flower stalks. Spots become brown and the entire leaf dies.Cercospora insulanaApply a fungicide to protect plants.
Red LeafLeaves redden.Cold weather or virus infection.Cold weather-injured plants recover. Virus-infected plants do not recover and should be destroyed.
Rhizoctonia Crown RotGray spots develop on leaves near the soil. The crown and entire plant die.Rhizoctonia solaniApply a fungicide to protect plants.
Seedling BlightSeedlings are killed.Alternaria, Botrytis, Stemphylium, Fusarium, Cercospora, and Colletotrichum.Produce seedlings from decorticated, hot water and fungicide-treated seeds.
VirusDepending upon virus involved, stunting, deformed leaves, mosaic, red leaves, red or yellow line patterns and ring spots may develop.Broadbean wilt, cucumber mosaic, statice Y, tobacco rattle, tomato bushy stunt or turnip mosaic virus.Destroy infected plants. Maintain good aphid control to delay virus spread. Wash hands and disinfest tools thoroughly after handling infected plants to prevent mechanical spread.
YellowsSmall leaves, yellowing, stunting, and excessive branching occur. Mature plant leaves may redden. Flowers may fail to open, be reduced in size, or have abnormal color and shape.PhytoplasmaDestroy infected plants. Maintain good leafhopper control to delay spread.
