How to deal with slugs on strawberries?
Most gardeners plant strawberries in their summer cottages. But at the same time, this berry is often exposed to various diseases and parasites. Today we will talk about how to deal with slugs in Victoria.
Description
Slugs are special terrestrial mollusks. They look like snails, but without a shell. Such a parasite often changes the shape of the body. This is due to the constant contraction of muscle tissue.
At rest, the mollusks are wide and short. When muscles contract, they suddenly become thinner and longer. On the surface of the body, such creatures secrete a large amount of mucus in the form of foam. It is necessary in order to protect it from drying out in too hot weather. And also such a substance does not allow the slug to injure its body during friction when it moves.
Their body color is gray-brown. In the head section, the mollusk has two pairs of special tentacles. At the end of the first are the eyes. The second pair is for tactile sensations.
Slugs are nocturnal. In the daytime, they carefully hide under the shade of strawberry leaf blades or under wood. Under the influence of ultraviolet radiation, these animals quickly dry out, which leads to their imminent death.
Harmful molluscs live for about 1-2 years. They lay their eggs once a year. Their number does not exceed forty pieces. After one month, full-fledged mollusks hatch from the eggs.They can grow to adult size in a couple of months.
When do they appear on strawberries?
Slugs most often eat not only ripe young strawberries, but they also love the juicy leaves of this plant. In addition, there are several more important factors for the appearance of this pest on fruit beds:
- too hot summer;
- excessively high yields;
- unkempt area with a lot of weeds;
- a large number of dead organic residues in the garden;
- too waterlogged and dense earth;
- high density of strawberry rows.
signs
The presence of slugs in their country beds can be determined by several signs:
- the appearance of deformed fruits;
- the presence of white mucus inside the berries;
- the formation of holes in the leaf blades;
- small spots of silvery color on plants.
In the daytime, such pests are almost impossible to see, because they parasitize only at night. They hide, as a rule, on leaves from the underside or in ground cracks. Pests eat young juicy leaf plates.
Fighting methods
Many gardeners in the fight against slugs prefer folk methods.
- Topping with dry mustard, slaked lime or wood ash. To get rid of them on strawberries, sprinkle damaged bushes with this remedy (30 grams per square meter of land).
- Solution with mustard powder. To prepare such a remedy for parasites, this component (4-6 tablespoons) is diluted in clean water (10 liters). They are carefully sprayed with diseased bushes.
- Ingredients with instant coffee. The product is poured with hot water and the damaged leaves are sprayed with the resulting liquid immediately on both sides.Such processing is recommended to be carried out in the evening or in the afternoon, but in dry weather.
- Film mulching. It is best to take such material of a dark color. At night, slugs will accumulate under it, because it is humid there, and this affects them favorably. During the day, due to heating under ultraviolet rays, pests die, as they cannot withstand too high a temperature.
- Infusion of hot pepper. A fresh vegetable (one kilogram) is poured with water (10 liters). In this form, everything is left to infuse for two days. After the broth is boiled for an hour. It is cooled, and the pods are thoroughly rubbed. The liquid is placed briefly in a cool place. Then she is taken out and the diseased seedlings are sprayed with her.
- Sprinkle with egg or nut shells. To protect strawberries from snails, the ground around it is treated with this component. In this case, such a tool acts as a prickly barrier for slugs.
- Dry land overlay. These mollusks love moist areas, therefore, in order to completely get rid of them, a layer of dried earth is poured onto the ground. This should be done after you water the plants.
- Solution with ammonia and vinegar. To make this composition, you need to mix them with water (1 part of the components to 6 parts of water). After the resulting solution, infected steles and leaf blades are carefully processed.
Some gardeners remove these terrestrial molluscs from their country beds by hand. But this method of pest control is the most time-consuming and inefficient. After all, this will help protect the berries for a short time.
Often gardeners use various baits for them. So, you can place old boards, plywood or even roofing felt near the strawberry rows.It is also recommended to moisten the ground on which they will be located with water, this will further attract pests that quickly accumulate on such materials.
Instead of this kind of bait, some gardeners take ordinary polyethylene. In the morning, a considerable amount of condensate will accumulate under this material. A moist environment is favorable for shellfish, so many parasites will appear there. In the daytime, under the action of sunlight, the polyethylene will heat up, which will lead to the drying of their bodies and the imminent death of the slugs.
In order to get rid of these animals, you can scatter sharp barriers (coniferous branches, sharp gravel, sawdust, river sand) in different parts of your summer cottage. These mollusks cannot overcome such obstacles due to the special structure of the body.
Most gardeners in the fight against snails prefer proven and effective chemicals.
- metal hydride. It is this tool that is most often used to remove slugs on strawberries. It is in the form of granules. They are scattered around the area. Sometimes metal hydride is also available in the form of a special powder. It should also be poured onto the soil around damaged seedlings.
- Fresh lime. To treat the bushes from pests with this component, it is also carefully scattered on the soil around the diseased strawberries. Instead of freshly slaked lime, it is allowed to use ground iron sulfate.
- chlorine mixture. It consists of bleach and ash. Instead of the latter, you can add tobacco dust. To save strawberries from parasites, this mass is poured onto the ground.
- The preparation "Thunderstorm". The composition of this drug includes metaldehyde. It comes in the form of small granules.They cultivate the soil around damaged plants (15 grams per five square meters of land). Remember that during fruiting, such a tool is not recommended. Often "Thunderstorm" is used as an effective bait for slugs.
Prevention
To prevent slugs from appearing on strawberry beds at all, you need to regularly do some procedures. Do not forget to remove all debris and organic residues from the soil in time.
Destroy all weeds located next to the seedlings. In autumn, it is recommended to carry out deep digging of the soil. This is necessary in order to get rid of the eggs of various parasites that are stored in the ground.
Animals that destroy snails should also be attracted to the land. These include birds, hedgehogs and frogs. In order for them to appear in your beds, you need to build a small pond, place small baits or install tiny houses for wintering.
Often slugs are exterminated by moles, snakes, lizards and shrews, because such pests are their favorite delicacy. But these same animals can not only destroy parasites, but also cause serious harm to the plants themselves on the site.
Remember that you should not feed them to poultry (hens, roosters, ducks). After all, these mollusks are often carriers of various infections, due to which animals can get sick and die.
Remember that they are also repelled by various odorous plants. Such plantings include garlic, sage and rosemary. You can't water the rows too often. Excessively moist soil will only attract slugs and contribute to their spread.
Recommendations
Some gardeners advise planting strawberry seedlings in artificial raised beds.Their height must be at least 30 centimeters. Also, many advise periodically removing thickening in berry beds, as it attracts slugs and some other pests. To do this, the rows with seedlings must be thinned out.
Do not forget to regularly weed and loosen the land with strawberry plants. These procedures can be replaced by mulching. For the preparation of mulch, coniferous branches or crushed sawdust are most often used.
