Aphid is a small pest, up to 1.5 mm in length, which provokes the death of any plant on which it appears. Thanks to the finest proboscis - the stylus, which easily penetrates the stems and leaves of plants, it feeds on their juices. Aphids on cucumbers are just as dangerous as any other pest or disease. Therefore, at the first signs of its occurrence, it is necessary to take drastic measures. The article will describe how to deal with aphids on cucumbers, what methods and means for this use.

What hurts aphid cucumbers?

Oddly enough, cucumbers quite calmly endure the attack of aphids, in any case, if it is a small colony. Of course, this will affect the leaves, but with abundant watering, care, the pest will not cause serious harm to the crop. By itself, aphid leads to the fact that the leaves of the plant become thinner, fall down, wither. But a large colony of aphids can lead to the death of a sprout in a matter of days.

Folk remedies to combat aphids on cucumbers

  • Neem oil or insecticidal soap is added to ordinary water. After mixing, the water is poured into the sprayer and the affected areas are treated with it. This method removes aphids from the plant, but does not kill it, so the treatment must be carried out repeatedly with a break of 3-7 days (as soon as it is noted that the aphid has returned to cucumbers).
  • The infusion of tomato tops or potatoes, garlic, celandine, dandelion is one of the most accessible recipes of the folk remedy to combat aphids. Approximately 300 grams of one of these plants should be poured with 12 liters of boiling water. After settling the mixture for 2 days, it is filtered and the cucumbers are sprayed with the resulting liquid.
  • For 1 bucket of water, take 2 tablespoons of ash (preferably it should be ground to dust, without large lumps), and a bar of laundry soap. Immediately after the ingredients are mixed and the soap has dissolved, the mixture can be poured into a container and sprayed on the cucumbers.
  • The sulfur checker is a very effective method that destroys not only aphids, but also fungal infections, but there are a few nuances. First you need to buy it, and this is not available to everyone. It is used mostly in greenhouses, since when the wind is outside, all the gas will pass by the plant. And finally - this method can be used only in the fall, when the entire crop has been harvested.

When treating a plant with any of the suggested folk remedies, it is necessary to direct the pressure of the solution directly onto the aphids that live on cucumbers (leaves, stems), and not on top of the plants. Moreover, separate attention should be paid to the inner side of the leaves, since it is there that most of the pests "live".

It is important to note that if some plant is severely affected by aphids, it is advisable to completely pry, remove from the site and burn outside. The fact is that large colonies are strong, they quickly recover and move to neighboring cultures, so you can not take risks.
