In the greenhouse production of vegetables and flowers, snails are a serious problem and can cause great damage. Their number depends on the conditions prevailing in the production units (greenhouses). The most harmful are slugs. However, against them there are also some biological or chemical methods that you can use to get rid of these attacks.
Naked snails are easy to recognize. Their body is elongated and narrow without outer shell, covered only by a slimy mantle. They occur mainly in hidden, dark and damp places and spend the day there. They are active in the early evening and at night. Their appearance is first can be seen by the light trail that they leave behind, as well as the visible damage they cause to vegetable crops (they make round bites on the leaves).
They multiply throughout the summer, and each female lays a up to 500 eggs from which new individuals appear in 20 days. Their numerical status can be astonishingly large as well as the damage they cause. That is why it is very necessary to deal with the problem in time and use all available means and knowledge in order to won the battle. Snails are used in greenhouse production they suppress preventivelymechanical, biological and chemical measures.
3 ways to keep snails out of your garden!
Preventive measures in greenhouses and greenhouses include regular humidity control using fans, regular ventilation and application of a drip irrigation system. With this system, moisture is directed directly to the cultivated plant and in this way prevents its spread over the entire surface of the land, which avoids the creation of favorable conditions for the residence of snails.
Mechanical measures include the collection and destruction of snails. For this purpose, tiles, wooden planks, moistened cloths can be used in places where snails are collected. It is known that snails attracts beersqueezed orange peel, grapefruit, sprouted wheat, potato, chopped apple. In order to protect the crop, lime, ash, shavings, sand, salt, egg shells are sprinkled around the bed.
It has been observed that setting thin wires around the greenhouse or greenhouses connected to a weak current prevents the appearance of snails in the cultivated crop. Also the installation of various mechanical barriers, copper or tin plates around the bed 15 to 20 centimeters above the ground, provided that all snails inside the bed are collected immediately after setting up barriers. By planting plants around the bed with vegetables that repel snails with their scent, such as wormwood, fennel, anise, rosemary, garlic, horseradish, thyme, poppy, damage is prevented on cultivated culture.

As biological measures in the surrounding countries to control snails used by predatory nematodes Phasmarhabditis hermaphrodita. They first stir them in water, and then leave them for three to five hours to activate. The solution is used in the evening by treating plants and watering the land. After their application, the plants should be well watered so that the nematodes reach deep into the soil.
Chemical measures imply the use of limacid and molluscicide preparations such as Arion (5 g pellets per m2), Gardene (5 g pellets per m2), Pužomor pellets, Mesurol granulate (30-50 g per m2). Do not cultivate the land for 20 days after their application. Pelete i granulate it should be placed in the afternoon, taking care that the preparation does not fall on the cultivated plant. Spreading of the preparation is done between the rows. It should be taken into account that the use of poisoned limicide baits and molluscicides causes soil and water pollution, and therefore death of organisms who live there.
In organic agricultural production for snail control iron (III) phosphate pellets are used. The product is non-toxic. After feeding with iron pellets, snails stop feeding and gradually dehydrate. Pellets are placed in vessels as baitsso they are not in direct contact with the plant or the soil and do not pose a direct danger to birds and pets.
