An experienced gardener knows how to cultivate the soil from a wireworm destroying a potato crop. Article by https://bishonenworks.com.
A harmful insect appears if the owner does not pay attention to cultivating the soil and does not use drugs to protect garden crops.
To destroy the larvae of the malicious pest, the following agricultural measures are carried out:
- solution treatment;
- soil mulching.
An effective tool for pest control is loosening the soil between rows of vegetables. Timely plowing of the field, cultivation methods contribute to the exit of larvae to the surface of the earth, where they die. To destroy pests using a method such as compaction of the soil.
If a summer resident finds a parasite, he tramples a wide strip near the part of the garden where he saw the pest. Tamper protects garden crops from damage.
Often use special tools, such as cut potatoes, which half peeks out of the soil. The pest falls into a trap, which is then immersed in boiling water.
In autumn, marl is introduced into the soil, and at the beginning of March – stone flour in the amount of 5 kg per 50 m².
After harvesting, the land is dug up, because the soil is depleted from planting and cultivation. In addition, wireworm larvae are still on the surface and have not gone deep into the ground, hiding from severe frosts. The digging of the site must be carried out carefully. During digging, small roots and pests should be chosen. With a decrease in temperature, parasites die within 2-3 days.
Larvae that remain in the ground freeze or die of hunger.
Gardeners use spring tillage, with which they destroy exterminated pests. Experienced summer residents in time notice signs indicating depletion of the soil:
- the earth looks like dust after rain;
- hard crust appears;
- smells of mold and rot are felt.
As soon as the summer resident notices these symptoms, he begins to introduce nutrients into the soil. The wire lives in an acidic environment, in order to destroy the pest, it is necessary to lower the pH of the soil. Gardeners fertilize the earth with mixtures containing nitrogen, which has a detrimental effect on the larvae.
Summer residents suggest using:
- ammonia fertilizers;
- ammonium sulfate (30 g of the drug is added per 1 m²);
- potassium chloride (10 g per 1 m²).
Make the following top dressing: lime, dolomite flour, pink solution of potassium permanganate (10 g diluted in 20 l of liquid).
Chemicals against parasites
Chemical pesticides are used to kill pests. The following drugs are used:
- Voliam Flexi;
They have the following effects on pests:
- destroy wireworms in direct contact;
- poison the larvae;
- paralyze central nervous system parasites;
- neutralize pathogenic microorganisms.
In March-April, nematodes are introduced into the soil, which contribute to the death of larvae.
Pest control plants
In the fight against wireworms, summer residents are helped by siderates – plants that affect soil fertility. They lower the pH of the soil, and the parasite is not able to live in such a soil.
Cultures are a natural remedy that does not affect human health.
The most useful are:
- oilseed radish;
- sowing alfalfa, which loosens the soil;
- rape (universal remedy);
- fodder beans (intended for heavy soil);
If siderates are planted for several years, the wireworm dies quickly. New offspring seek other habitats. Cereal plants are the insect’s favorite food.
You should not plant plants in those places in the garden where the larvae of the pest are found. Eating well, an adult individual wireworm after 3 years completely infects the soil.
Preventive measures after harvesting vegetables
Garden crops are not always affected by insects, but to preserve the harvest, the summer resident takes measures: after collecting vegetables, he destroys the tops and weeds on the beds.
You should regularly determine the pH of the soil and add substances to the soil to reduce its acidity.
The summer resident fights with weed, especially wheat grass is especially dangerous. Siderata are sown as soon as the snow melts. They plant the entire area of the garden in order to remove them and fix them in the ground in the winter. Plantings of legumes, alfalfa, lupine should not be too thick.
Keep in mind the crop rotation scheme.
The summer resident alternates crops on one bed in order to replenish the amount of nutrients. After cruciferous soils, many harmful fungi remain in the soil, so the next year they plant potatoes or dill with parsley.
In autumn, the remains of plants are burned, and the soil is treated with a pink solution of potassium permanganate. Rotted manure is poured on the beds.
Wet, shaded areas should be identified in the garden, because the wireworm often reproduces in these places. The pest does not settle in the beds where such plants grow as:
Experienced gardeners advise: it is necessary to sow salad in the garden, which feeds the pest, an adult plant should be dug together with the larvae and destroyed.
The summer resident finely cuts the leaves of celandine, nettle, coltsfoot, dandelion, observing a proportion of 1: 5: 2: 2. The composition is poured with liquid in an amount of 10 l and insisted in an enameled container for 3 days. The solution is treated with soil 3 times with an interval of 7 days.
You can get rid of an insect by using several methods of its destruction at the same time. A special role belongs to the prevention of infection, because with its help you can get rid of pests and prevent their further appearance in the suburban area.
