🔍 Possible Causes (11)
Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.

Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.

Nitrogen Deficiency
Nitrogen deficiency occurs when plants lack sufficient nitrogen, an essential macronutrient needed for chlorophyll production and overall growth. This deficiency typically manifests as yellowing leaves, starting with older foliage and progressing to newer growth if left untreated.

Phosphorus Deficiency
Phosphorus deficiency is a common nutritional problem that hinders healthy plant growth. Phosphorus is essential for root development, flowering, fruiting, and energy metabolism. When deficient, plants exhibit stunted growth and leaves with purple or reddish coloration, especially on older leaves.

Step 1
Zinc Deficiency
Zinc deficiency is a common nutrient disorder that affects plant growth and development. Zinc is an essential micronutrient required for enzyme function, chlorophyll formation, and protein synthesis. Without adequate zinc, plants exhibit characteristic symptoms including interveinal chlorosis, stunted growth, and deformed leaves.

- • Stunted plant growth with shortened internodes
- • Overall reduced vigor and slow growth rate

Step 1
Sulfur Deficiency
Sulfur deficiency is a nutrient disorder that occurs when plants lack adequate sulfur for normal growth and development. Unlike nitrogen deficiency which affects older leaves first, sulfur deficiency primarily manifests in younger leaves because sulfur is not mobile within the plant. Sulfur is essential for protein synthesis, enzyme function, and chlorophyll formation. This deficiency is more common in sandy soils, soils low in organic matter, and in high-rainfall areas where sulfur can be leached away.

Pythium Root Rot
Pythium root rot is a serious fungal disease caused by various Pythium species including P. aphanidermatum, P. ultimum, and P. irregulare. These water molds are present in practically all cultivated soils and attack plant roots under wet conditions, causing rapid wet rot that can extend into the stem. The disease is favored by poor drainage, overwatering, and specific temperatures depending on the species.

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.
✓ Related symptoms:
- • Stunted growth in severe cases
⚡ Quick Fixes:
Remove and destroy all infected plant parts. For severe infections, remove entire plant.
Mosaic Virus
Mosaic virus is a group of plant viruses that cause mottled, patchy patterns on leaves and can affect a wide variety of plants. The virus creates characteristic yellow, white, and green mosaic patterns, often accompanied by stunted growth and deformed plant parts. This highly contagious disease spreads rapidly through insect vectors and contaminated tools.

Step 1
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.

Caterpillars
Caterpillars are the larval stage of moths and butterflies that feed voraciously on plant foliage, stems, flowers, and fruits. Common species include cabbage loopers, tomato hornworms, armyworms, and cutworms. These pests can cause extensive damage by consuming large amounts of plant tissue in a short time. They vary in size from small (1/4 inch) to large (5 inches), with colors ranging from green to brown, often featuring stripes or spots. Caterpillars are highly mobile and can quickly spread throughout gardens, making them one of the most destructive common pests.
