Pests, herbicides, or environmental factors can all cause tomato leaves to curl. Learning to recognize the cause is the first step toward solving this common problem. Pests, herbicides, or ...
Blossom end rot on a grape tomato. Calcium deficiency symptoms appear initially as localized tissue necrosis leading to stunted plant growth, necrotic leaf margins on young leaves or curling of the leaves, and eventual death of terminal buds and root tips. Generally, the new growth and rapidly growing tissues of the plant are affected first.
Tomato leaf mold is a plant disease originated from the South and Central America. [1] In 1883, Cooke first discovered the tomato leaf mold in North Carolina. [2] This disease is not common on the fruit, but if the control is not run, the foliage can be greatly damaged and result in significant yield losses.
Symptoms of TYLCV infection include severe stunting, reduction of leaf size, upward cupping/curling of leaves, chlorosis on leaves and flowers, and reduction of fruit production. This virus can cause significant yield losses from 90–100%, and it is estimated that about 7 million hectares can experience TYLCV infection or mixed virus ...
Curly top is characterized by stunting of the plant and deformation of leaves and fruit. The petioles and blades of the leaves curl, twist, and become discolored. [2] Beet curly top virus causes curly top disease in beets and is carried by the beet leafhopper (Circulifer tenellus) [3] throughout arid and semi-arid locations. [4]
Celebrity tomatoes are resistant to Verticillium Wilt, a fungal disease which causes a yellow colour to plant leaves and eventually causes the leaves to wilt and die. [19] It is also resistant to Fusarium Wilt which is a fungus found in the soil that infects the roots of plants, stopping plant growth and causing leaf necrosis. [ 11 ]
Symptoms of tomato yellow leaf curl virus, including chlorotic margins and interveinal yellowing, were found in several tomato and tomatillo crops in Mexico and Guatemala in 2006. [31] After laboratory tests, the virus was confirmed. Symptomatic plants were associated with the presence of whiteflies, which were likely the cause of this outbreak ...
Septoria lycopersici infects the tomato leaves via the stomata and also by direct penetration of epidermal cells. [3] Symptoms generally include circular or angular lesions most commonly found on the older, lower leaves of the plant. [1] The lesions are generally 2–5 mm in diameter and have a greyish center with brown margins.
