Spraying tomatoes in June and July

The most common and dangerous diseases that can threaten tomatoes are various rot, spotting and late blight. As for pests, parasites such as whiteflies or mites can cause serious damage to your plant. Elementary spraying can help to avoid these unpleasant situations. It is necessary to spray in two cases, for the prevention of the disease and when it is necessary to treat the plant.

There are also such frequent problems as a small number of ovaries or their complete absence, slow growth of tomatoes and lack of fruits. Spraying foliar top dressing will help to cope with these troubles.

Also, spraying is a particularly good method in heavy soil, when nutrients are poorly supplied to the soil. It will contribute to the fertility of the plant, even in such difficult conditions.


Tomatoes tend to often carry diseases, and it does not matter whether the plant grows in a greenhouse or in an open garden, so everyone needs the necessary protection. The easiest way is to spray the leaves.

Experienced gardeners-tomato growers do regular procedures, starting from June 10-15. Basically, this is prevention from phytophthora, because it is this disease that is considered the most frequent and dangerous. For spraying, you can use furatsilin, quadris or other means.

There are also biologics that are best used for early fruits. They can be eaten 3-4 days after the procedure. Such a tool is, for example, Fitosporin. It is diluted in water in a ratio of 1:10. The procedure is carried out approximately once every two weeks throughout the season.

If the plant has already shown signs of any disease, then drugs such as Penncozeb or Bravo should be used, they are fungicides and can quickly cure your plantings, as they are the most powerful. Also isolated such a drug as Ridomil Gold. It should be noted that it is not suitable for prevention and should only be used if the plant is really infected.

When spraying, make sure that no liquid drips from the leaves, the solution should be evenly distributed throughout the plant. Do not forget about the temperature of the “medicine”. It is advisable to use it warm, as tomatoes do not tolerate cold or hot watering very well.

From larvae and whiteflies, drugs such as Fitoverm, Phosbecid and other insecticides help well. And in order to get rid of the spider mite, use Aktara, Aktellik or also Fitoverm. Remember the instructions, never neglect it and follow all the recommendations.

Feeding tomatoes in June

In June, tomatoes should be fed for the first time. This is necessary for strong roots, for building mass, as well as for tasty fruits. For the first spraying, it is recommended to use urea, approximately in the following ratio: 50-60 grams per 10 liters of water. In case of blanching of the leaves, add magnesium sulfate (one and a half grams for each liter of this solution).

Further, after the first ovaries appear on the inflorescence, the plant should be treated with a phosphorus-potassium solution. The ratio is approximately the following: 10 grams of superphosphate, about 8-9 grams of potassium sulfate, add to 10 liters of water.

Frequent plant diseases may be due to a lack of copper, so treatment with copper sulfate is recommended. The effect will be enhanced if you do this when the leaves begin to curl. The ratio in the solution will be as follows: 1-2 grams of copper sulfate per 1 liter of pure water.


At the time when the tomatoes begin to bear fruit, they should be treated with a solution of wood ash, boric acid and iodine. Preparation: add about 1.5-2 liters of ash and 10 grams of acid to 5 liters of boiling water, then let the mixture cool and bring the volume of the solution to 10 liters. After that, add iodine (one vial), and leave the solution to infuse for a day. To treat the plant, mix 1 liter of this product with 10 liters of water. This solution will help to significantly speed up fruiting and increase the immunity of the plant.

There are also drugs that are designed to stimulate growth. Yes, of course, plants will respond positively to them, but remember that such things should not be abused!

Spraying tomatoes in July

Many varieties of tomatoes bear fruit in July, so their protection is more difficult for gardeners. Fortunately, there are a lot of folk remedies that are ideal for the prevention of various diseases.

You can spray the plants with whey. It will create a thin film on the leaves and will not give pests a chance to reproduce. Preparation: Mix 1 liter of whey (sour milk or kefir) with 3 liters of plain water. Spraying should be carried out approximately 2-3 times during, in our case, July. If the plants grow planted in an open garden, then repeat the procedure after rain.

Around the twentieth of July, treatment with preparations containing copper should begin. This will prevent late blight and brown spotting. We recommend paying attention to such drugs as: Barrier, Oksihom, etc.

If suddenly you find leaves on your plant that have been infected with late blight, then immediately remove them and burn them! This will prevent an epidemic

If we talk about pests in the July period, then here are the main ones: a bear, a wireworm and a scoop. Try to constantly inspect plants, remove insects and treat the soil with insecticides. For example, Bazudin or Zemlin. Also spraying with Arrow will help from the aforementioned nibbling scoop.

Also, the plant may lack calcium. This will be evidenced by the twisting of the leaves and spots on the fruits themselves. In this case, the bush should be treated with calcium nitrate (2 grams per 1 liter of water). After that, do not worry, the fruits are saved!

Top dressing of tomatoes and tomatoes with minerals

It should be remembered that tomatoes about a couple of times a month must be comprehensively fed with the necessary minerals. To do this, you need to dilute about 1-2 tablespoons of nitroammophoska in 10 warm water. Next, spray the bushes with this solution. You can also add wood ash to this product (about 1-2 cups).

Remember that tomato bushes, both in greenhouses and in open beds, must be sprayed regularly! Do not hesitate, after the above tips, you can easily build a work plan for caring for this plant for several weeks in advance.
