Root rot diseases typically occur in wet substrates due to over-watering, poor drainage, or containers standing in water. The plants were set out in a container 10 days ago, and have been producing flowers since. Roots infected with black root rot develop dark spots or bands that are easily seen against the normally white pansy roots. They do well in full morning sun, but really not in full afternoon sun. High soluble salt concentration in the potting substrate also favors Pythium infection by stressing the root system. Are yours shaded from the afternoon sun? All root rot pathogens are soil-borne, meaning that they survive in substrates and debris. Contact information is at the end of this article. They generally grow as a small tree with a divided trunk close to the ground. Cercospora leaf spot – Cercospora leaf spot discolors pansy leaves beginning with purple-black lesions on lower leaves that eventually develop pale tan centers with bluish-black rings and water-soaked areas.

Pansy bloom colors span the color wheel, from black to white, red to orange to yellow, and purple to true blue. Boron (B) Deficiency symptoms are initially expressed on the new leaves and stems, with growth being distorted or clubby. Infected leaves fall off the plant and it is presumed that the fungus survives within the leaf debris. It's been in the high 80's to low 90's for the last week.. Leaf abscission occurs after prolonged deficiency conditions. Test the irrigation water to determine available levels. Pythium survives in soil and on anything that contains soil, including hands, shoes, pots and equipment, as well as in contaminated water sources. During fall production in the mid 1980s, growers in warm regions began noticing Mottle Pansy Syndrome (MPS). Maintain a cool production environment for pansy plugs. Nitrogen Deficiency: Plants deficient in nitrogen exhibit slow growth, stunting, lack of lateral shoot growth, or (with advanced conditions) lower leaves that initially turn greenish-purple to yellow (chlorosis). Delta Marina. The “purpling” begins at the tips or undersides of the leaves, and moves its way across the entire leaf. Remember to add supplemental B applications if using calcium nitrate (Ca(NO3)2) + potassium nitrate (KNO3) and your irrigation water lacks B. Corrective Fertilization: Corrective drench applications of Borax or Solubor at 6.25 ppm of B (see mixing rates below) can be applied to soilless substrates. Also, the stalks are turning dark purple. The older leaves start turning a dull, dark green, which then turns to purple. The fungus produces abundant spores within the leaf spots or other affected plant parts that are spread to adjacent plants by water splashing. Solution: Begin fertilizing with a phosphorus-rich nutrient formula after the leaves appear.

I've read it could be a nitrogen deficiency, or a phosphorus deficiency.. but what's got me confused is that it's only the pansies that seem to be having any troubles. They have been in partial sun. They also like a slightly acidic soil. By scouting plug trays, growers can eliminate these plants before they become a problem. 2. Fungicides can reduce infection of new leaves, but they will not cure already infected leaves. The black discoloration is due to fungal spores within the root. Excess levels of N will result in dark-green coloration, reduced plant growth, and delayed flowering. As a rule, the small flowering types have many more blooms at any given moment. Pansy flowers come in all sorts of colors from white, yellow, purple, through to my favorite – blue. Corrective Fertilization: Applications include calcium nitrate (Ca(NO3)2), potassium nitrate (KNO3), or Excel 15-5-15 Cal-Mag at the rate of 300 to 400 ppm N. A single corrective N fertilization will return the lower leaves to the normal green color within one to two weeks. Remember, the test for the effectiveness of a fungicide spray is not whether the existing leaf spots go away (because they never will), but whether new growth remains free of infection. Colorful Viola.. The variegated fritillary is a brownish-orange, spotted and speckled, medium-sized butterfly that is sometimes noticed on pansies in mid to late summer and early fall. Pick Your Pansies. As they feed, they secrete a clear sticky liquid called honeydew, which sooty mold, a dark gray or black fungus, grows on and ants eat. Disease Cycle: Anthracnose is caused by the fungus Colletotrichum violae-tricoloris. Pansyworms (variegated fritillary) are small, spiny caterpillars that are appropriately named because they feed on pansies and other plants in the violet family. If using calcium nitrate (Ca(NO3)2) with potassium nitrate (KNO3), remember to supply P, Mg, and micro-nutrients to the plants. "Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?"

Management: Fungicides typically used for control of Pythium such as etridiazole, fosetyl-Al, mefenoxam, and propamocarb can stunt young pansies, so apply fungicides with caution during the first week after transplant. Symptoms appear as an interveinal V-shaped chlorosis with green veins, and downward cupping of the younger leaves. Pansies can be infected by the usual root-rot pathogens such as Pythium, Rhizoctonia, and Fusarium, but they also are susceptible to Thielaviopsis, the cause of “black root rot.” Black root rot is the most serious root disease of pansies primarily because it is very difficult to control. 2) Purchase quality seed and report significant amounts of variegation to the seed supplier. Applying fungicides, including mancozeb, myclobutanil, chlorothalonil, fludioxonil, or thiophanate methyl + mancozeb, at seven to 14 day intervals can reduce disease development and spread. Initially, the infected leaves have pale yellow spots with distinct black margins. They are still flowering, but they haven't grown much in the 2 1/2 weeks they've been in the ground, and the lower leaves are turning purple.
