Wilt can attack tomatoes, eggplants, strawberries and even trees such as olive trees, vines and other fruit trees.
Verticillosis of the tomato: remedies, symptoms and how to care for plants. Among the tomato diseases, theverticillosisit is configured among those of fungal origin.
Verticillosis, plant disease
Thereverticillosisis a fungal disease caused by the pathogens Verticillium dahliae and Verticillium alboatrum. These agents can affect numerous arboreal and herbaceous essences. In addition totomato, verticillosis fungi can affect:
- Olive tree
- Cherry tree
The two pathogens can survive in the soil for very long periods. They thrive on the most diverse crops and are resistant to the most adverse conditions.
THEmushroomsVerticillium dahliae and Verticillium alboatrum survive in the soil year after year, crop after crop. Given their ability to attack the most disparate crops, the rotation of the garden alone cannot be enough as a preventive remedy. If your tomato, strawberry or eggplant plants are attacked byverticillosis, we recommend that you perform preventive treatments on a periodic basis.
THEsymptomsare common. The symptoms described for thewilt of tomatothey can also be found, for example, on aubergines and other horticultural crops.
There verticillosisit first occurs on the basal leaves of plants, and then extends to the upper leaves as well. On plants affected by verticillosisa form of foliar drying which extends progressively from the apex towards the petiole.
The two fungal microorganisms manage to infect the tomato plants (eggplant, strawberries or other cultivars) penetrating through the root tips or exploiting wounds of various origins, especially through the wounds localized to the collar of the plants.
The collar of the plants represents the point of insertion of the roots on the stem, it is the point where the plant inserts itself into the ground and is susceptible to blows of "hoeing "clumsy.
THE symptoms of verticillosis, a fungal disease also known astracheoverticillosis, occur due to poor lymph circulation. Tracheas and tracheids represent the systemvascularof the plant, these are small ducts that allow the passage of sap from the substrate to the leaves.
There verticillosisslows down or prevents the circulation of lymph with consequent wilting and leaf drying, which can affect a part or the whole plant.
The diseased tomato plants, affected by the da tracheoverticillosis, can survive for a shorter or longer period, depending on the extent of the infestation. The tomato or eggplant plants affected by verticillosisfail to offer good productivity even in the case of minor attacks. In case of acute fungal attacks, the plants wither and die quickly.
Tomato verticillosis, remedies
THEremediesvisas for thewilt of tomatocan also be adopted in the case ofwilt of eggplant or other horticultural plants. It is the same fungus so the remedies are similar.
Theplantssubject toverticillosisthey must be replaced with healthy plants. It sounds sad to say but… it is much easier to eliminate the plant than to cure it.
The affected plants, in fact, must be removed from the garden and burned to avoid further spreading the disease to other healthy plants in the garden.
If you want to avoid anytreatment, for a couple of years, where tomatoes were grown, avoid growing vegetables susceptible toverticillosislike:
If you have a limited plot of land and cannot avoid cultivating certain plants, we remind you that on the market it is possible to buy resistant or tolerant varieties.verticillosis.
When you buy plants at a nursery, ask for varieties that are "resistant to wilt" or, if you start from seed, choose sachets of seeds with the initials "V" or "Ve".
After eliminating the diseased plants, treat the healthy plants with a copper oxychloride or Bordeaux mixture. Repeat the treatment after 15-20 days.
Copper oxycloide and Bordeaux blue mush are cupric antifungals, allowed in organic farming. They are easily found in garden centers or agricultural consortia. Those who prefer can aim for online shopping.
On Amazon, an excellent Bordeaux mushroom-based fungicide is priced at € 10.80 with shipping costs included. For all information, I refer you to the product sheet "to this Amazon page".
