How to treat tomatoes from late blight with Trichopolom or Metronidazole

Phytophthora is a serious disease of nightshades, which must be treated in order not to lose the entire crop. To fight the infection, not only specialized means help, but also ordinary pharmaceutical preparations such as Trichopol and its cheaper analogue Metronidazole. It is recommended to process tomatoes with "Trichopolom" first as a preventive measure, since phytophthora is much easier to prevent than to eradicate. But it is also possible to stop the development of the fungus with the help of these available means.

Phytophthora in tomatoes: what it looks like, favorable conditions for the fungus

The disease late blight causes a fungus. Spores are found in the soil, as well as in poor quality seeds. Plants can also become infected with the help of the wind, which carries pathogens from nearby plantings or a neighboring area. Phytophthora requires urgent intervention, since a week after its discovery, there is a high probability of losing the entire crop.

How the disease manifests itself: first, dark brown spots form on the bushes - you need to look for them on the lower part of the leaf plate. Further, the fungus progresses, moving to the stem and fruits. If late blight has developed to this stage, then you will have to remove and burn the plantings, it will no longer be possible to cure them.

What conditions allow the phytophthora fungus to develophit and hit tomatoes:

1. Dense plantings. These shrubs receive little light needed to kill the fungus. When planting tomatoes, a distance of at least 0.7-1 m must be observed. And one should not forget about thinning stepsons.
2. High humidity. Water should be applied as needed in moderation. Drops should not fall on the leaves - water is poured strictly under the root. Excessively moist soil should be loosened after watering.
3. Weak root system. This mistake should be avoided already at the seedling stage. The roots are fed with complex fertilizers. When transplanting, tomatoes are moved along with a lump of earth, being careful not to damage the roots.
4. Overfeeding with nitrogen. Such "fattening" leads to a weakening of planting immunity: the element is required for tomatoes only at the stage of green growth.

"Trichopolum" and "Metronidazole" against late blight

Pharmacy preparation "Trichopol" intended for the treatment of fungal diseases in humans, but it is also effective against late blight on tomatoes. The tool helps to destroy pathogenic microorganisms in the early stages of their development. The drug is available in tablet form. The advantage of Trichopol is safety for the plants themselves.

"Metronidazole" from late blight on tomatoes is as effective as its more expensive counterpart, and is available in the same form as tablets.

In both cases, a solution is prepared from the drug. For efficiency Trichopolum or Metronidazole mixed with brilliant green, iodine.

When to process

Processing of tomatoes for preventive purposes is carried out from early spring. You need to start by treating the seeds before planting. Then the young seedlings are watered with the solution. In the fall, it also does not hurt to process the soil for planting tomatoes through watering.

For treatment, tomatoes are processed in early June, since it is in this month that late blight begins to actively manifest itself. No more than 3-4 treatments are carried out with an interval of 10 days. The last operation is recommended to be carried out 2 weeks before harvest.

Advice! The drugs must be alternated with other treatments, since the fungus tends to adapt. For replacement, folk remedies are used: dairy products, saline solution, tobacco, ash.

How to treat tomatoes with Trichopolom

How to apply Trichopolum for tomatoes infected with fungus:

1. 20 tablets of "Trichopol" are first diluted in a small amount of warm water. Then the mixture is poured into a bucket, which is filled with water up to 10 liters.
2. Overdosing is not allowed, as there is a danger of plant burns.
3. So that the product does not drain from the foliage, but lingers on it, liquid soap is added to the solution.
4. Processing is carried out in the morning, in warm, calm and dry weather.
5. The entire bush is sprayed, but special attention is paid to the lower part of the leaves - this is where the pathogen is located.
6. Even if the rest of the bush is outwardly healthy, it is still recommended to process it, since the fungus can be found in all parts.
7. To treat the root system, the soil around the bush is watered. For one plant - 50 ml of solution. Not enough, but it will be enough.
8. The solution cannot be stored, therefore it must be used on the day of preparation, preferably immediately after the tablets are dissolved. The rest will have to be poured out.
9. The procedure is carried out once every 10 days.
10. If it rains on the chosen or the next day, the procedure is repeated (for outdoor plantings), since the Trichopolum solution is easily washed off.
11. If the plant has been pruned, then you should not rush to the treatment with "Trichopolom" and other antifungal agents. Slices on the stem should be tightened - you should give them at least 3-4 hours.

Advice! When treating the affected bush, it is necessary to spray the drug with the neighboring plantings, even if there are no traces of the disease on them.

Additives to the solution "Trichopol"

For greater efficiency, greenery is often added to the finished solution. The tool is an additional anti-fungal component. For 10 liters of ready-made solution - one bottle.

For the same purpose it is allowed use iodine... Enough 15-20 drops of the product for a ready-made solution of 10 liters.

How to use Metronidazole

"Metronidazole" is an analogue of "Trichopol", they have one active ingredient.

How to spray tomatoes with the drug:

1. The proportions of water and tablets are the same as in the case of "Trichopol": 20 pieces per 10 liters.
2. The infected plantings can be treated both by spraying and by watering the soil around the bush.
3. If tomato leaves curl up, they are carefully wiped with a solution on both sides.
4. Does not harm plants if you combine Metronidazole solution with green stuff.

The best remedy for late blight on tomatoes is careful care at all stages. Late blight will not affect the bushes if they are properly planted. Preventive measures are much more effective than treatment. The development of the phytophthora fungus can only be slowed down, but the plant is unlikely to be completely cured.
