Processing tomatoes with home spray

Modern breeders work tirelessly and create new hybrids and varieties of tomatoes every year. They, and all of us, want the new varieties to be tastier than the varieties we plant. It would be good if they sang earlier and were stored longer. But probably the most important thing is that they are resistant to major tomato diseases. Unfortunately, there are simply no varieties and hybrids that are resistant to them at the genetic level. If they try to sell you such a tomato, then the seller is simply lying.

But there are varieties and hybrids of tomatoes that quite successfully resist the main scourge of nightshades - late blight. The gardener will only need a little help with the plant, for example, cleaning up a tomato. This will significantly reduce the risk of this dangerous disease. It also fights Alternaria blight on tomatoes.

Main signs and methods of spread of late blight

Late blight or late blight is a disease of tomatoes and other crops from the nightshade family, including potatoes. Late blight is caused by pathogenic fungi. Weakened plants are usually the first to get sick. Appear on stems and leaves brown spots. If you look closely, you will see a delicate white fluff on the other side of the leaf. These are zoosporangia that are easily transferred from plant to plant.In a humid environment, spores of the causative agent of the disease emerge from them, which enter the plant through stomata or germinate directly through the top layer of tissue.

As a rule, potatoes are the first to suffer from late blight. Fungal spores can be found on healthy-looking seed tubers and in the top layer of soil. From diseased potatoes, the disease spreads to tomatoes. The time from potato disease to tomato disease is only a week, maximum ten days. In sunny weather, spores may die. Wet and cold summers with sudden temperature changes and fogs contribute to the rapid spread of late blight.

This will not only reduce the risk of disease in both crops, but will also increase the growing season of potatoes, and, therefore, their yield. Hom-treated potatoes do not like the Colorado potato beetle.

In order to prevent late blight spores from infecting tomatoes, it is necessary to create a protective layer on the leaf surface of the plants, and also to treat the tomatoes with a substance that, by infecting the spores of the pathogen, would destroy them. The drug Hom meets each of these requirements.

Khom preparation and treatment of tomatoes with it

Hom is a contact fungicide. What does it mean?

• This drug cannot cure already diseased plants, but it reliably protects them from infection, forming a protective film on the leaves and stems. Due to the nature of the action of the drug, treatments should be preventive in nature and begin before late blight occurs not only on tomatoes, but also on potatoes.
• It practically does not penetrate into tissues, concentrating on their surface.
• Copper oxychloride, which is the main active ingredient of the drug, destroys the cells of the pathogen, causing its death, but only on the surface of the plant.
• Pathogenic organisms do not get used to the action of the drug. Therefore, each treatment will be equally effective.
• Treatments can be carried out repeatedly, on average three to five times, since the drug does not accumulate in the plant.
• The validity period of each treatment is from ten to fourteen days.
• The drug completely decomposes in six months into components that are not dangerous to humans.

How to use hom

For standard treatment of plants, according to the instructions, ten liters of water are added for every forty grams of the drug. First, prepare a concentrated solution by dissolving copper oxychloride in a small amount of water, and then add the rest of the water. Since the processing rate for tomatoes is no more than one liter per ten square meters, such an amount will clearly be unnecessary. Storage of this solution is not provided. Therefore, you need to focus on the area occupied by tomatoes, and, of course, tall varieties will require more solution consumption, since they have a larger leaf mass.

Features of processing tomatoes with homemade

There are rules that, if followed, will help make the treatment not only as effective for plants as possible, but also safe for humans.

• Prepare a fresh preparation each time.
• Observe the proportions when preparing it and the processing standards.
• Tomatoes are processed on a clear and windless day.It is better to do this in the morning or late in the evening. The air temperature during processing should not exceed 30 degrees.
• When processing, pay attention to the underside of the leaves, since pathogens often settle on it.
• Be sure to wear special clothing, gloves and use a respirator. You cannot smoke or eat.
• After treatment, you need to change clothes, wash completely and even rinse your mouth.
• Keep the drug away from food and use specially designated containers for its preparation.
• Do not use iron containers or galvanized steel utensils. Copper oxychloride reacts with iron, and the composition and properties of the solution change.
• Do not allow the home to come into contact with alkalis, they decompose it.
• Do not store the drug at temperatures above thirty and below five degrees Celsius.
• The drug has a third hazard class. It is toxic to fish and should not be released into water bodies. In the first six hours after treatment, the drug is toxic to bees.
• Processing during flowering of tomatoes is undesirable.
• Hom is compatible with most modern pesticides and fungicides of other classes, except those that have an alkaline reaction. It is possible to combine with some fertilizers and immunostimulants, for example, humates and epin.

Taking into account the peculiarities of home treatments of tomatoes, it is better to carry them out before flowering, as well as between the flowering of the first and second flower cluster. During other periods of the plant growing season, it is possible to carry out treatments with compounds that have no restrictions and no waiting period, that is, the treated tomatoes can be eaten on the day of the treatment.

Late blight is an insidious and unpredictable disease. Preventing it is much easier than treating it.
