The most terrible enemy of a potato is consideredColorado beetle. This pest raids the fields and destroys the green part of the plant. But if this is a visible danger, then there is also a hidden one. The fight against the wireworm can become much longer and more difficult. And often you find defeat only when you start digging a crop. Filled with complex pests of the pest, the tubers lose their ability to be cured, and even when cleaning, a significant part of the root will be removed. How to recognize the danger in time and protect your planting from it?
It's a larva of a click beetle. Outwardly it is a yellowish caterpillar or worm, which really looks like a wire. They are very difficult to crush. The body, covered with chitinous shell, can withstand considerable loads.
The fight against the wirewoman should begin longbefore planting potatoes. Otherwise, a gluttonous larva will deprive you of harvest. In the spring there is not much edible on the site, so the potatoes planted by you will become a roof over your head, and a tasty lunch. So, you can not wait for friendly shoots. No wonder there is such a trick. In spring, potatoes are buried in a greenhouse. A wireworm is gathered from the whole site. Then the root is removed and destroyed.
If the site is affected by the larva of the click beetle, theneven under the condition that your plantations will ascend and be able to harvest, there will be little joy from this. More than 60% of the tubers will be trenched. While the damaged potatoes are in the soil, flesh around the hole is filled with putrefactive bacteria, nematodes and worms. As a result, the crop becomes conditionally usable for consumption. Yes, and the wireworms, left in the tubers after digging, also do not please. Such potatoes can not be welded or cleaned.
The fight against the wireworm must be conducted constantly,on all fronts. The fact is that the larva does not abhor and succulent roots. As a result, the plant does not receive proper nutrition and the yield is sharply reduced. If you do not grow potatoes on the site, this does not mean that the danger has passed you. Yellow larvae with a dense membrane are widespread almost everywhere. They will gladly destroy any garden culture. Therefore, the fight against the wireworm is one of the first tasks of the summer resident.
The best solution to the problem is to prevent it. And the task is quite solvable. The wireworm is very fond of moist soil, so liming is one of the ways to fight. For this you can use lime, chalk and ash. But the best and proven method is limestone, dolomite flour. It is introduced into the soil only once every 3-4 years.
For the same purposes, eggshells are also used. Just scatter the shredded shell on the ground. But this method has a drawback. The concentration of substances from the shell quickly dissolves, so it is important to repeat the procedure on a regular basis.
At this time, the larvae gather for wintering. Therefore, when digging the soil, try to collect them by hand, and remove the remaining roots in the soil. The more pests you can collect and destroy, the less chance the offspring will have in the next year. Usually in the autumn the colony gathers on the site where your favorite root crops grow. It can be not only potatoes, but also carrots. The extraction of insects into the air leads to their death, especially if digging is done shortly before the onset of cold weather.
But this is only a measure to contain the population. The fight against potato wireworms should include a whole range of different ways. Because of the abundance of juicy food, the potato field is very attractive for this pest.
With the onset of warm days, every summer residentis selected for his plot. The first task is to bring the vegetable garden in order and dig up the ground, preparing for a new season. If the site is small, try to lay out the vegetables-traps. It can be any root vegetables. You can put a glass jar or cover the ground with a piece of polyethylene, so that it warms up better, and dig up the vegetables. Heat and food will attract larvae from all over the site.
Mechanical digging is another waystruggle. During it, some of the larvae are destroyed by a shovel or a mechanical plow. Some individuals can be selected manually. Part of the population will die in the sun or be eaten by birds.
During spring work in the soil is recommendedmake fertilizers that contain nitrogen and ammonia. They are extremely unpleasant for the wireworm, so he will try to relocate to a neighboring site. In addition, the pest is uncomfortable on soils with low acidity. Experienced gardeners recommend adding several granules of superphosphate to each well.
Since this vegetable is the basis for manyration, people take care that it does not contain harmful substances. For mechanical pest control, baits and traps are often used, which are located along the perimeter of landings or between ridges.
There are modern insecticides that are accuratewill lead to the death of the pest, but they are dangerous for humans. It can be "Metarizine" and a number of other drugs. Therefore, they are used in a slightly different way. Take a few dozen tubers and soak in a poisonous solution. After that, tie them in gauze pouches and dig all over the site. The pest will not just gather in it, but eat and die.
Fighting a wireworm on a potato fieldshould be diverse. Do not let the pest penetrate your site - this is also an important part of the work. As measures of scaring, you can take the following:
If the place allows, then it can be excellentmeasure of struggle against a wireworm. Soil pests, and bacteria, too, do not affect plants that are planted on this site for the first year. They do not seem to know about no. But with each new year the losses will be more serious. Therefore, it is recommended to alternate potatoes with unattractive plants for the wireworm. This is bean and spring rape, buckwheat. Such measures will allow not only to save planting from pests, but also will enable the soil to rest well and be filled with useful trace elements.
In August, after harvesting, you can sowplace for potatoes with mustard, alfalfa and clover. This will entail the death of insects or their hasty relocation to a new place of residence. The fight against the wireworm in the sector must go along all fronts, so that the enemy does not have a chance to stay on it.
This is a very corrosive substance that can harmand the plant itself. Therefore, proceed as follows. Sawdust with chicken droppings collected in the hen house should be added to each hole when planting. A large handful is enough. This method of combating wireworm is natural and very simple. By the autumn you will notice that the affected tubers are much less. Repeat the procedure every year - and soon on the site there will be no insects left. Thus shoots will be juicy, strong, dark green.
If you choose radical means of struggle, thenpay attention to preparations like "Prestige". Before planting the tubers are soaked in a special solution, after which they cease to be attractive to insects. Two things should be considered:
Therefore, for processing potatoes of early varieties,which is excavated after 40 days, this method is not suitable. And if the time of maturation is not less than 80 days, then it is required to introduce additional methods of struggle so that the pest does not spoil the already ready tubers. All the methods listed above, in this case, will do. It is possible to plant the salad between the rows closer to the end of the action of the drug. The pest prefers it to all other garden plants, so it will attack the succulent roots. Noticing that the leaf wilts, dig out the bush and destroy the wireworms.
The fight against the wireworm in the garden isa set of measures, each of which has the right to exist. At the same time, none of them can be called full and sufficient. Therefore, each gardener chooses for himself several of them. Usually these are traps, crop rotation, planting of plants, which are a pest delicacy or repel it from the site.
