clutch of eggsAfter 10-25 days, young individuals – nymphs – hatch from the eggs. Over the next 30-45 days, the nymphs molt 5 times. It is the nymphs of the bug, the harmful turtle, that damage the grains of cereals, stems and foliage of plants.

With the onset of winter cold weather, the insect hibernates. Bedbugs hibernate under fallen leaves in gardens, in private plots, in forest belts, stumps and felled trees.

The bug the turtle pierces the stem or leaf with a sharp proboscis, injecting digestive enzymes inside. They cause decomposition processes inside the plant and its rapid wilting. Such a culture can no longer bear fruit, since the process of sap flow is disrupted and quickly dies..

What the harmful bug damages the bug:

  • spring and winter wheat;
  • oats;
  • millet;
  • corn;
  • rye;
  • sunflower;
  • sainfoin;
  • barley.

Fighting the bug harmful turtle

agrotechnical methods of dealing with bedbugs with a harmful turtleGiven the extremely fast rate of reproduction and the ability to destroy the entire crop, the control of the turtle bug should begin immediately after the first pests are identified. For this, agrotechnical, chemical and folk methods of struggle are used, aimed at reducing the number and limiting the feeding of larvae, as well as the destruction of adults..

Many farmers and agronomists choose agrotechnical methods of dealing with bedbugs with a harmful turtle. They are safe for plants and future crops, and also allow you to get rid of pests without the use of insecticides..

Basic agrotechnical methods of control:

  1. Planting plants deep enough.
  2. Careful selection of planting material.
  3. Tight landings. The tighter the crops, the lower the risk of a turtle bug, as it will not have enough moisture and light.
  4. Timely feeding of crops – bugs do not tolerate nitrogen-containing fertilizers, especially ammonium nitrate.

To prevent the appearance of pests, early sowing of cereal crops is desirable. Thanks to this, the crop can be harvested before the turtle bug larvae appear..

Natural enemies can be involved in pest control. The harmful turtle is afraid of centipedes, ants, and hedgehogs. Therefore, if these insects appear in the garden, the risk of attack by a harmful turtle is reduced..

  • Decis;
  • Actellik;
  • BI-58;
  • Sumition;
  • Leptocide;
  • Talstar;
  • Clipper.

Insecticidal preparations give a quick result, as the fruits and grains are exposed to chemicals. The undoubted advantage of chemicals is the ability to effectively process a large area in a short period of time..

The composition of chemicals includes neurotoxic poisons that block receptor connections in the body of insects, leading to their rapid paralysis and death. They are dangerous to the human body, therefore, processing should be carried out only with the use of safety equipment..

Biological agents

use of biological agentsBiological products are less hazardous than pesticides. They contain components of biogenic origin, which are analogs of natural compounds contained in bacteria and other living organisms..

Effective biological products:

  • Eforia KS;
  • Ezhio;
  • Fitoverm;
  • Kinmix KE.

When using biological preparations, it must be borne in mind that in the body of the bug the turtle quickly develops resistance to toxins. That is why for the complete destruction of pests, you need to change the drugs used at least once a season..
