Arthropods |
Beet armyworm damage
Identification tip:
Feeding is quite messy with webbing and frass. |
Green peach aphid adults.
Identification tip:
Generally pale green although some individuals may be pinkish. There are both winged and wingless forms. |
Leafminer damage.
Identification tip:
Larvae mine between upper and lower leaf surfaces, creating winding, whitish tunnels that widen as the larva grows and eventually cause necrosis. |
Pepper weevil larva damage.
Identification tip:
Larvae feed within the fruit, usually at the seed core and fill the fruit with frass. |
Thrips damage.
Identification tip:
Thrips feeding distorts foliage and can cause leaves to curl and pucker. |
Tomato fruitworm damage.
Identification tip:
The larvae burrow into the fruit and feed on the seed core or flesh depositing frass. Infested fruit decay. |
Diseases |
Alfalfa mosaic virus symptoms.
Identification tip:
Leaves of infected plants have distinct yellow or whitish mosaic patterns. |
Cucumovirus mosaic diseases.
Identification tip:
Infected chilies are distorted and have a bumpy surface. |
Curly top symptoms.
Identification tip:
Internodes of infected plants shorten, resulting in extremely stunted plants. The upper portion resembles a rosette or small flower bouquet. Leaves turn yellow or light green and may roll upward. |

Impatiens necrotic spot symptoms.
Identification tip:
Fruit show chlorotic spots, red or green areas surrounded by yellow halos, and concentric rings that may become necrotic. Symptoms are similar to those caused by another tospovirus, Tomato spotted wilt virus. |
Potyvirus mosaic diseases.
Identification tip:
Fruit may be misshapen and have a bumpy surface. It can be difficult to distinguish fruit with cucumber mosaic disease from those with potyviruses. |
Pepper tobamovirus diseases.
Identification tip:
Although symptoms vary among cultivars and virus strains they generally include necrosis on any plant part, defoliation, leaf distortion, and/or mosaic symptoms on leaves, stems, and eventually fruit. |
Phytophthora infected fruit.
Identification tip:
Fungal spores from crown and root rot can splash on fruit and cause it to decay. Symptoms include water-soaked patches that dry up and form lesions. |
Powdery mildew.
Identification tip:
A patchy, white, powdery growth enlarges on the lower leaf surface and at times on the upper surface. |
Tomato spotted wilt virus symptoms.
Identification tip:
Infected fruit may have mosaic patterns or spots. |
Verticillium wilt symptoms.
Identification tip:
Symptoms include yellowing and drooping of leaves on a few branches or on the entire plant. Brown discoloration is visible when the roots and lower stem of a wilted plant are cut open. Symptoms are unlikely to be seen in seedlings. |
