KIVSYAKI – PHOTO AND DESCRIPTION
This year there were small worms in the greenhouse (see photo). Please tell me how to deal with them.
Answered by Raisa Petrunino, plant protection specialist
Small worms that appear in a greenhouse are called worms. These are not insects, but soil inhabitants from the class of millipedes. They usually live in the surface layer of soil, in leaf litter, feeding on rotting organic matter and plant debris, contributing to their transformation into humus.
On personal plots, nodule can be found in a greenhouse, under boards, stones, or in a pile of leaves. When widespread, they often gnaw the fruits of strawberries, tomatoes, and melons lying on the ground, without causing much harm. Chickweeds can actively damage plants only in cold and wet spring, when they have no food, gnawing cavities in the root system of immature shoots, or in hot weather with a lack of moisture. They especially love strawberries.
Larvae often accumulate in the depressions they make. As for other vegetables and fruits, they prefer rotten ones. But they don’t refuse fresh ones, especially if they are located close to the ground. All juicy fruits are at risk: sugar beets, zucchini, cucumbers, potatoes, carrots, melons, tomatoes, as well as fruits that have fallen to the ground.
Millipedes overwinter in the soil, often under leaf litter, but if there is rotten wood, hollows, or compost, then millipedes readily reproduce and lay eggs here. Depending on weather conditions, offspring appear in 2-4 weeks. The larvae develop very slowly, going through several molts. The lifespan of the nodule is 4-5 years. Outbreaks of their reproduction are repeated with the same frequency.
FOR THE NOTICE
Centipedes usually arrive in garden plots with leaf litter. humus or manure.
The most common way to deal with nods – regular manual collection. The nooses are active early in the morning, late in the evening and on rainy, cloudy days. When you touch them, the nooses often secrete a pungent secretion with a specific odor, which turns their hands red or brownish-violet. Sometimes this secretion causes an allergic reaction, so when going hunting for nodule, use gloves.
Centipedes can be lured to a certain place and then collected and destroyed there. To do this, early in the spring, rotten potatoes are laid out (zucchini, pumpkin or carrots are also suitable). Baits can be made poisonous by soaking vegetables with insecticides, which are usually used against the Colorado potato beetle. It is good to cover the baits with cardboard boxes; the fish likes to process plant fibers and wood cellulose.
They also strongly dislike the mixture made up of equal parts of tobacco, lime and ash. It is sprinkled on places where centipedes gather. At the same time, slugs also disappear.
For wintering, the grasshopper prefers dense and uncultivated soil. To reduce its numbers, it is necessary to dig deep into the ground in late autumn or early spring. Cold is a fairly effective means of combating larvae and adults. If weather conditions allow, then in the spring, before planting the main crops, it is good to sow cruciferous green manure (rapeseed, white mustard, rapeseed).
You can protect strawberries from grass by mulching the ridges with pine litter, sawdust, straw cuttings or agrotextiles.
As for chemical control agents, at the moment there are no recommended preparations for protecting plants from grasshoppers. And the use of drugs Pochin, Zemlin, Grizzly against them. Medvetox, aimed at destroying wireworms and mole crickets and containing diazinon, does not give noticeable results. And the harm from their introduction to humans and the environment may be much greater than from nox, which are harmful only under certain conditions.
