Tomato yellow leaf curl virus
The virus is transmitted by Whiteflies (Bemisia tabaci). It is not seed-borne. Tomato plants infected early in the season are normally stunted and excessively branched. Affected leaves are chlorotic and are curled upward. Flower drop is common, and therefore, infected plants have a reduced number of flowers and fruits.
- Use resistant or tolerant varieties such as "Tengeru 97", "Amareto", "Peto 86", "Fiona F1", "Perlina", "Denise", "Cheyenne" ("E448"), "Rover", "Roma" and "Marglobe" is highly susceptible and should not be used in areas where the disease is common.
- Protect seedbeds with a white nylon net (40 mesh), as the later the plants are infected with the virus the less impact the disease will have on yield reductions.
- Eradicate weeds.
- Rogue out diseased plants (in the seedbed and in the field) and destroy them.
- Plant barrier crops.
- Avoid continuous growing of tomato.
