How to deal with aphids on cucumbers?

Gardeners who dream of a large crop of delicious cucumbers, always think about how to protect their planting from various pests. Most often vegetables attacking aphid. Already in the middle of summer, the pests are settled in the beds and in order not to lose the harvest, it is necessary not only to intervene operatively during the work, but also to take preventive measures. To combat this pest is recommended as folk remedies, and chemicals.

Gourd aphid attacks all parts of cucumbers: leaflets, shoots, stems, and fruits, the juice of which it feeds. It looks like a small insect with thin legs. Its size is barely out of the frame of 1-2 millimeters. The black or dark green adult is distinguished by the absence of wings. Sometimes it is white, almost transparent. Pests inhabit, as a rule, colonies, which stand out brightly against the background of green cucumbers in their black color.

Besides the fact that aphids weaken the fruits of plants, depriving them of their liquid, it also poisons them with evolving poison. In addition, the pest is able to tolerate common infections. To determine the emergence of aphids in the beds can be as cucumber leaves - they begin to curl, turn yellow and become covered with spots. In addition, there is a fall of flowers and ovaries. In general, the aphid begins to settle on the seedlings, and young shoots with a pair of leaves cannot even resist it, so it is important to take measures immediately.

Whichever method of insect control is chosen, it should be remembered that the procedure must be carried out according to the instructions, and be prepared that one treatment may not be enough. In addition, all spraying would be good to perform before the scorching sun, because the plant must dry out. Otherwise, the cucumbers will turn yellow, dry out and be burned.

Gardeners "old school" usually prefer to deal with aphids on cucumbers through the use of folk remedies. Since the use of chemistry during fruiting is prohibited, but the appearance of aphids is quite possible, "grandmother's recipes" come to the rescue. Conveniently, all the ingredients are extremely affordable, and they can be found either in their own garden or in the house.

Especially popular are herbal solutions. For example, you can try to handle planting solution celandine. Its recipe is simple: 400 grams of a plant for two days infused in a liter of water. After this, the broth will boil for about half an hour. You can use and dried yarrow. The grass stays in a water bath for 40 minutes in 2 liters of water, and then infused for a couple of days in a dark room. If you spray cucumbers several times with dandelion infusion, you can get rid of aphids. Shoots and roots are poured with water, after which they infuse for 24 hours and then filtered. Spray the plant to be four times, observing the interval of one day.

Pest control can also occur through the use of available material such as tomato and potato tops. The green parts infuse for several hours in water, and 1 kilogram of tops should be poured with 10 liters of liquid. The resulting solution will need to sprinkle cucumbers.

Finally, the infusion of garlic cloves can be saved from the threat. Fruits are laid out together with dried celandine in glass containers and poured with warm water. It takes about 500 grams of garlic cloves, and they must be cleaned. After the solution is infused for 4 days, 25 milliliters of it are diluted in 10 liters of plain water.

Acetic solution will help to protect cucumbers from black aphids.Vinegar in the amount of 200 milliliters is dissolved in 10 liters of water, after which they can spray plants every three days. If the pest appeared after the ants, in parallel it is necessary to deal with them. Dry mustard powder will help from both problems. It either crumbles in the habitats of insects, or is bred in water and used for spraying.

When a pest occurs in a greenhouse, a mixture of 30 grams of pepper, 200 grams of tobacco dust and 10 liters of water is often used. To enhance the effect, you can add ingredients such as soap flakes and wood ash. The latter is generally often used with this culture, because besides fighting insects, it also enriches the plant. To make a spray solution, you should take 200 grams of soap chips, 200 grams of wood ash and dilute them in 10 liters of water.

Ammonia will come to the rescue. He, in the amount of 50 milliliters, together with 25 grams of soap chips, dissolved in 10 liters of water. The resulting liquid can either spray the green part of the landings, or wipe the sheets with it a couple of times a week. Hydrogen peroxide will also be useful. A three percent solution in the amount of 50 milliliters is mixed with 50 grams of sugar and a liter of water.

Soda is the basis of various aphid countering recipes. For example, 70 grams of powder and 15 drops of any essential oil are mixed and dissolved in water. Everything is agitated, and the resulting liquid cucumbers are sprayed every two days. If tar soap was concealed in the closet, then it can be effectively applied. A third of the piece is stirred in water until completely dissolved, after which the plants are treated with liquid.

The main plus of potent chemistry is its immediate action. It is worthwhile to use such means in emergency situations: when too many landings are hit or when death of the entire crop is threatened. The minus of chemical treatment is that for almost a month after the procedure, it is forbidden to use the fruit, so you have to be prepared for the loss of some of the crop. They will just have to be plucked and thrown away. Proved such tools as "Aktara", "Intavir", "Akarin" and "Fufanon."

In general, all chemical insecticides are divided into three groups: contact action, system action, and organophosphate. In contact with the impact of an insect is poisoned, eating the leaves treated with drugs or die from direct exposure. In this case, the whole damaged plant is processed, and the sheets even from two sides.

Systemic insecticides duplicate the contact effect, but also are absorbed inside the plant when it is watered under the root. The juice inside the cucumber leaves becomes poisoned, but the aphid dies, even tasting another part of the plant. This method is considered more effective.

When nothing helps, and cucumbers die in the greenhouse, you have to use sulfur bomb. The most popular types are Climate, Pawn and FAS. This method allows not only to eliminate aphids, but also to poison ants and other pests. However, he has too many drawbacks. The nutritional value of the soil decreases, and the corrosion of the metal parts of the greenhouse begins. In addition, most checkers are advised to use only after the end of the season.

If popular recipes have failed, and it’s scary to contact chemistry, then you should try biological preparations. Biological solutions, which are also called phytopreparations, allow you to collect the fruits within a couple of days after processing.Their components paralyze the nervous system of pests that consume processed parts of cucumbers. As a result, the individuals stop feeding and die in a few days.

10 grams of powder are dissolved in a liter of water, and the resulting liquid is used for spraying. Positive feedback is present in the drug "Tanrek." Its 5 milliliters are stirred in 10 liters of cold water and, if necessary, supplemented with soap flakes, which improves adhesion to the leaves. If there is no heavy precipitation, the drug will be able to perform a protective function for a month.

Another effective drug is Strela. A bag with 50 grams of the substance is dissolved in 10 liters of water. It will have to be treated twice a week with insects and once a month as prevention. In addition, Iskra, Actofit and Fitoverm found their fans.

When aphids settle in cucumber greenhouses, methods of pest control and prevention are slightly different. The use of chemicals requires additional security measures, because their use in an enclosed space can adversely affect human health. At a minimum, you will have to protect the airways, and at the end wash your hands and face with soap and water. In addition, after spraying it is necessary to tightly close all the vents and doors.

On an enclosed ground, the fight against aphids will become more efficient when applied with potassium and phosphorus based fertilizers. Usually taken 20 grams of superphosphate and 10 grams of potassium sulfate, which is diluted in 10 liters of water. After this, splashing is performed.

In the fall, plant residues are removed from the greenhouse, and the soil is dug up. If possible, the top layer of soil changes or the soil is treated with chemical insecticides. Internal wooden elements are whitewashed. At the same time, the structure is fumigated with sulfur dioxide, but it is important to wait until the temperature drops below 10 degrees Celsius.

Preventive measures begin with the proper preparation of the greenhouse. Even before the seedlings are planted, the room is treated with a solution of blue vitriol, caustic soda or bleach. When planning the beds, it is important to leave a gap of 70 centimeters between the bushes. Too dense planting leads to active reproduction of aphids.

Do not forget about the regular airing, as well as the mode of watering and fertilizing. Between the rows of cucumbers you can plant mustard and dill, the smell of which will scare off the pest and attract its enemies. An important stage of care, as in the open field, is a regular check.

When aphids are only found in the greenhouse, gardeners are advised to eliminate the damaged plant. Then you should check for ant paths and, if necessary, destroy them. Following the glass are washed with copper sulphate, dissolved in water.

To protect the planting from aphids, even without letting it appear on cucumbers, it is necessary to carry out preventive measures regularly - several times throughout the season. It is also important to follow the rules of care. Aphids like to spend the winter months on weeds, so they should be eliminated regularly. It is better to burn the tops.

Protection is impossible without checks, so it is worthwhile to take it as a rule to periodically check the condition of the leaves, stems and fruits. If the insects can be detected at an early stage, then it will turn out to be limited to breaking off the spoiled leaves. Efficient cultivation in greenhouses is impossible without regular supply of fresh air. We must also not forget that the top layer of the earth needs to be changed every season.

In addition to what will have to be done during the growth of the plant, even at the stage of buying seeds, you can take care of the choice of a variety that is distinguished by maximum resistance to pests. Then the seeds themselves are kept in special solutions. A little later, it would be good to pick the right neighbors for cucumbers - onions, garlic, mint, the smell of which scares off insects.
