Often the work of a gardener is reduced to zero as a result of the spread of pests on berry bushes – ticks, caterpillars, weevils. A real salvation can be Fitoverm for strawberries that are already blooming or ovaries have appeared on it. The drug does not harm the environment and human health, belongs to the biological and effectively helps to protect the crop.
The drug is produced in ampoules or small vials.
What is Fitoverm
Fitoverm – an effective means of combating harmful insects, a biological type with a selective effect – has a detrimental effect only on certain types of living beings. The preparation is based on natural components, therefore it belongs to the third class of danger – it does not harm humans, bees and the environment. As a result of the treatment of strawberries with Fitoverm, the total death of pests does not occur, but their number is greatly reduced, which allows you to save the crop.
The drug is produced in a water-soluble form, in the form of an emulsion. It is easy to use, just follow the instructions for use.
Operating principle
Fitoverm is based on averomectins produced by the bacterium Streptomyces avermitilis. They belong to the poisons of the neurotoxic group, paralyzing arthropods. The latter cannot move, eat and die of hunger.
The substance enters the body of pests in two ways:
- Contact – penetrate through soft, loose covers.
- Intestinal – during meals, along with the parts of strawberries treated with the drug (leaves, flowers, berries).
After 6-16 hours after treatment, the pests cease to lead an active life, death occurs after three days. It will take seven days for complete extermination.
What pests does it help?
The biological preparation Fitoverm has a detrimental effect on most garden and horticultural pests. These include:
- Colorado beetle.
- Moth.
- Sawfly.
- Thrips.
- Codling moth.
- Leaflet.
- Whitefly.
- Aphid.
- Gall mite.
Strawberries are most often affected by weevils that gnaw on stems, buds, leaves and berries. The surface of their body is dense, scaly, therefore, with contact action, the insecticide is powerless. In order for the poison to reach its target, the insect must eat the processed parts of the strawberry. After 10 hours, the effect of the drug begins and the weevil can no longer eat.
Strawberries are harmed by both adults of the weevil and its larvae.
The spider mite does not gnaw the leaves, but sucks the juice out of them, as a result of which they dry out and die. To destroy the pest, it takes 12 hours for the poison to penetrate the tissues of the strawberry foliage, and then through the juice into the intestines of the tick.
The first signs of a tick are white and yellow spots on strawberry foliage.
Slugs love to eat juicy berries. Their surface is very delicate, therefore, after the Fitoverm solution gets on the integument of the pest, the action occurs already after three hours.
The slug lives for one to two years and lays about forty eggs each year.
Validity and waiting
The validity of Fitoverm on strawberries depends on environmental indicators. At high temperatures, it is more effective than at excessive humidity and cool weather. On average, the period of protection of a plant from pests after treatment is from five days to two weeks.
The waiting period for the drug is only two days. During the fruiting period, processing is carried out as follows:
- Harvest ripe strawberries.
- Spray the plants with Fitoverma solution.
- The next collection is carried out in three days.
Fitoverm quickly decomposes without accumulating in strawberry leaves and berries
Is it possible to process strawberries with Fitoverm
The main advantage of the drug is its safety and the possibility of using it three days before harvest. For strawberries, this is the best option. Often insects attack ripe berries when chemicals can no longer be applied, since the waiting period (time from processing to harvest) is at least three weeks. Fitoverm quickly decomposes, does not accumulate in the stems, so it is used at any time during the growing season of strawberries without harming the soil, plants, bees and humans.
Is it possible to process strawberries with Fitoverm during flowering
It is possible to treat strawberries with Fitoverm for several years, since pests do not adapt to the drug and its effectiveness lasts for a long time. The tool is used during flowering and fruiting without the threat of poisoning, since the drug is non-toxic and quickly decomposes.
The disadvantages of Fitoverm include the short duration of its action, which is why treatments are carried out several times throughout the season – from spring to autumn.
The best time to spray strawberries is in the evening. It is worth choosing a quiet, dry, calm weather. Depending on the lesion, at least four procedures are carried out – in early spring, during flowering, fruiting and after it ends.
One bush needs no more than 100 ml of solution
How to breed Fitoverm for processing strawberries
In order to breed Fitoverm for spraying strawberries, follow several rules:
- The required dose is dissolved in a small amount of water.
- Mix thoroughly.
- Top up with water to the recommended volume according to the instructions.
- Prepare the solution immediately before use.
- Use as a whole or dispose of residues after processing.
How to breed Fitoverm from weevil on strawberries
If holes appear on the strawberry foliage, and the buds and flowers wither, then the plants are affected by the weevil. Insects cause maximum harm when laying eggs in buds, so it is necessary to destroy the females in order to prevent this. Spraying is carried out when the peduncles are raised, but the buds are still collected in the outlet. After they are separated, it will be too late – the females have already pierced them and laid eggs, which the drug does not work on.
To treat the weevil, you need to dissolve 20 ml of the product in 10 liters of water. The resulting solution is enough to spray a hundred strawberry bushes. Processing begins immediately, as over time it loses its properties. Spraying is carried out three times per season with a break of two weeks.
How to breed Fitoverm from nematodes on strawberries
Nematodes are roundworms 1 mm long that live on the roots of strawberries. You can notice that the plants are affected by several symptoms:
- The leaf blades are wrinkled.
- Whiskers are shortened, and the number of flowers is much less than usual.
- The pubescence on the cuttings disappears.
- Red spots appear between the veins.
Fitoverm stops the digestive system of the worms, and they die. The drug can be used in powder or as a solution. In the first case, it is scattered over the surface of the soil and instilled or added to the wells during planting, spending 18 g of powder under one plant. You can shed the soil under the bushes with an aqueous solution of the Fitoverma emulsion – 3 ml per 1 liter of water.
To detect a nematode, it is necessary to carefully examine the rhizomes of strawberries.
What can Fitoverm be mixed with
It is not recommended to mix Fitoverm with other drugs and fertilizers that have an alkaline reaction. A temporary break in their application should be at least three days.
Without prejudice to the quality of processing, Fitoverm can be mixed with growth stimulants (Zircon, Epin), organic fertilizers and fungicides. Do not use it with insecticides and copper-based chemicals at the same time. In order to check the compatibility of drugs, they are mixed in small volumes. If the liquids stratify or precipitate, they are contraindicated in combination.
When and how to properly process a berry
In order for the processing of strawberries by Fitoverm after harvesting, before it or during the flowering period to give a guaranteed result, a number of rules are followed:
- Spraying is carried out in the evening, in good weather.
- Follow the dosage according to the instructions.
- Use personal protective equipment.
- Do not eat or smoke during processing.
- Do not use the dishes in which the drug was diluted for food storage.
- If the solution gets into the eyes or on the skin, wash them with plenty of running water.
Drug analogues
As analogues of Fitoverm, drugs are used, the active substance in which is aversectin C:
- Vertimek – used against sucker, aphids, mites indoors, toxic to bees.
- Akarin – destroys nematodes, duration – four days.
- Gaupsin – destroys fungi by 96%.
- Actellik – aimed at eliminating aphids, scale insects and weevil.
Conclusion
Fitoverm for strawberries is an ambulance in case of damage by insect pests. With timely and proper use, the drug will not only get rid of parasites, will save the crop, but will not harm the soil, beneficial insects and humans.
