It might be associated with Silverleaf Whitefly attack. Install yellow sticky traps and spray with Acetampride or Difenthuron. Thanks

Hi Mohammed, Why do you think that your tomato leads to destruction? Please ck underside of the leaves if you find any sucking insects. Then take a photo and upload please. Please note that tomato plant loves temperature range 20-25 degrees C. So, try to allow shade if temperature is more higher than the range. Can you explain in English please?

Tomato big bud Candidatus Phytoplasma aurantifolia; there are several strains of the phytoplasma identified in tomato throughout the world; the strain in the Pacific is in the phytoplasma group/subgroup coded 16SrII. This code refers to analysis of ribosomal RNA. Leaves are small, curled upwards and yellowish-green or purple . Stems become erect, short, thick and purple flower buds become swollen, with green petals - hence the name of the disease - and normally dormant buds develop shoots. Green fruits are hard, tough and woody. Plants infected early are bushy, because of the development of many branches. Spread of the phytoplasma is by leafhoppers. One leafhopper that spreads tomato big bud is Orosius argentatus, but it is possible that there are other species. This leafhopper lives and breeds on weeds, and moves to tomato (and other crops) during dry times. Spread can be over long distances, during leafhopper migrations. There is very little spread of the phytoplasma within crops of tomato. The phytoplasma survives in weeds, and in the bodies of the leafhoppers. Once leafhoppers become infected by feeding on a plant with phytoplasma, they remain infected for life. There are few ways to control phytoplasma diseases; if the damage is severe, it might be best to replant than suffer low yields. Before planting: Remove any "volunteer" tomato plants and weeds, especially those in the tomato family, from around nurseries and in and around field plots.Preferably, raise the tomato seedlings in a screen house or under an insect screen cover.Do not plant next to other susceptible crops, such as eggplant or capsicum. After harvest: Collect the plants together with weeds around the planting and burn or bury them. Thank you for reading and getting benefits in future!☺
