🚨 Serious Problems (6)
Downy Mildew
Downy mildew is a fungal-like disease caused by oomycetes (water molds) that thrives in cool, wet conditions. It affects a wide range of plants, causing yellowing leaves with fuzzy white-gray growth underneath, leading to defoliation and reduced yields if left untreated.
Symptoms:
Small green or yellow translucent spots on leaves • Yellow to brown irregular patches on upper leaf surfaces • White, gray, or purple fuzzy growth on leaf undersides
⚡ Quick Fixes:
Remove and destroy all infected plant parts. For severe infections, remove entire plant.: Remove and destroy all infected plant parts. For severe infections, remove entire plant....
Fusarium Wilt
Fusarium wilt is a serious fungal disease caused by the soil-borne fungus Fusarium oxysporum. The fungus invades roots and blocks the water-conducting vessels (xylem) of the plant, causing progressive wilting and eventual death. Host-specific forms of the pathogen exist that attack different plant species.
Symptoms:
Wilting during the hottest part of the day with recovery at night (early stage) • Asymmetrical yellowing of leaves (one side of plant or leaflets) • Progressive upward wilting from the stem base
⚡ Quick Fixes:
Remove Plant: Immediately remove entire infected plant with roots. Dispose in sealed trash (DO NOT compost)....
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Symptoms:
Wilting leaves despite moist soil • Yellowing or browning of leaves • Stunted growth and poor vigor
⚡ Quick Fixes:
Emergency unpotting: Remove plant immediately from wet soil. Speed is critical....
Gray Mold (Botrytis Blight)
Gray mold, caused by the fungus Botrytis cinerea, is one of the most common fungal diseases in plants. It affects over 200 plant species, including ornamentals, vegetables, fruits, and houseplants. The disease thrives in cool, humid conditions with poor air circulation, causing grayish spots and soft rot on infected tissues.
Symptoms:
Grayish colored soft, mushy spots on leaves, stems, and flowers • Gray fuzzy coating of fungal spores, especially in high humidity • Brown to gray circular spots on leaves and petals
⚡ Quick Fixes:
Remove and dispose of all visibly infected parts: Remove and dispose of all visibly infected parts...
White Mold
White mold (Sclerotinia sclerotiorum) is a devastating fungal disease affecting over 400 plant species worldwide. The fungus produces black, seed-like structures (sclerotia) that can survive in soil for 5 or more years. The disease is favored by cool, moist weather (50-68°F/10-20°C), especially during flowering.
Symptoms:
Sudden wilting and yellowing of leaves • Fluffy white mold growth on stems and leaves • Water-soaked lesions expanding irregularly
⚡ Quick Fixes:
Immediate removal: Remove and completely destroy all infected plants. Burn or bag and dispose in trash....
Root-Knot Nematodes
Root-knot nematodes (Meloidogyne species) are microscopic roundworms that parasitize plant roots, causing characteristic galls or knots. These soil-borne pests are among the most economically damaging plant pathogens worldwide, affecting a wide range of ornamental and edible plants. The nematodes inject enzymes into root cells, causing abnormal swelling and disrupting water and nutrient uptake.
Symptoms:
Characteristic galls or knots on roots (1-10mm in diameter) • Root swelling, distortion, and excessive branching • Yellowing of leaves (chlorosis), especially lower leaves
⚡ Quick Fixes:
Step 1: Remove and destroy all infected plants and roots...
