Spider mites, aphids, and other insects destroy entire crops and damage bushes and trees. Instructions for use are supplied by the manufacturer with each package of Vertimek insecticide. Following the instructions, it is possible to cope with insects and save the plant from death.
Pests of cucumbers
On vegetable crops, aphids that drink the juice from the leaves appear during the fruiting period. They curl, the ovary crumbles, and the bush disappears. Spider mites infect cucumbers grown in greenhouses. The pest settles at the bottom of the leaves and draws moisture from them.
The root-knot nematode, which is only 1.5 mm long, loves the roots of the crop.Having taken root in the tissues, it releases toxic substances, under the influence of which growths are formed where the larvae settle.
Vertimek copes with mites and thrips, fights other types of pests on cucumbers, garden crops and flowers.
How does the insecticide work?
The active component of the drug is abamectin. This substance is formed when bacteria living in the soil begin to ferment. The chemical group to which it belongs was isolated in Japan at the end of the last century.
When spraying a plant, the insecticide solution penetrates into the leaves. The insect swallows the composition along with the juice. Vertimek releases gamma-aminobutyric acid, which acts on the nervous system of pests, so they are paralyzed. From the surface of the leaves, abamectin quickly moves into the tissues. The drug has virtually no effect on birds and beneficial insects.
To obtain a positive result when processing cucumbers indoors, the solution must be sprayed evenly over their surface, making sure that drops of the composition do not drip from the leaves.
Advantages of the insecticide
Vertimek effectively protects cucumbers from mites, which are not affected by other acaricides. The drug copes with thrips and leafmining insects, and has certain advantages compared to many insecticides:
- After spraying, it immediately penetrates into the leaf tissue.
- Protects crops from pests for a long time.
- Does not deteriorate the structure of plants and is well tolerated by them.
- The insects are paralyzed for an hour or two.
- Has little impact on beneficial fauna.
There are no spots left on the leaves when the crop is processed. After spraying, cucumbers can be consumed after three days.The insecticide belongs to hazard class 2, but it affects pests not only through the intestines, but also through contact.
If there is an insect invasion, the plant is treated again after a week.
Cucumbers and other crops should not be sprayed at high temperatures and high humidity.
To prevent pests from getting used to the composition, the drug must be alternated with Pegasus, Actellik, which have a different mechanism of action.
How to use insecticide?
Timely use of Vertimek for cucumbers saves the plant from death and quickly destroys insects. Treatment should begin as soon as pests begin to appear. Sometimes one spray per season is enough. If there is a need for a repeated procedure, the treatment is carried out a week later, during the heat after three days:
After the composition gets on the leaves, the cucumber bushes are covered with film for a day. Vertimek should be used 2-3 hours after dilution.
To cope with thrips, just dilute a teaspoon of insecticide in a bucket of water. When spraying plants against ticks, dissolve 2.5 ml of Vertimek in 10 liters of liquid.
To treat cucumbers against leaf miners, which gnaw tunnels in plant tissues, 1 gram of acaricide is mixed with a liter of water.
Security measures
Despite the fact that the insecticide belongs to toxicity class II, it must be handled with care. In case of contact with the skin, the composition can cause a burn; if inhaled, it leads to irritation of the nasal mucosa and redness of the eyes. To avoid the presence of unpleasant phenomena it is necessary:
- Spray the crop in the morning or evening when there is no wind.
- During the procedure, avoid eating, smoking, and drinking.
- Protect your eyes with goggles and your breathing path with a respirator.
- After treatment, wash your face and hands with soap.
The insecticide does not lose its properties for 4 years if stored in a dry, cool room, where the temperature is not lower than minus 15. Food and medicine should not be nearby.
If Vertimek gets into your eyes, rinse them with running water. In case of poisoning with the drug, induce vomiting, drink several tablets of activated carbon, and consult a doctor. You should not take medications that depress the nervous system. After using the acaricide, the packaging must be burned.
