Often, the work of a gardener is reduced to zero as a result of the spread of pests on berry bushes - ticks, caterpillars, weevils. Fitoverm can be a real salvation for strawberries that are already in bloom or have ovaries on them. The drug does not harm the environment and human health, belongs to biological and effectively helps to protect the crop.
What is Fitoverm
Fitoverm is an effective means of combating harmful insects, biological type with selective action - it has a detrimental effect only on certain types of living beings. The preparation is based on natural components, therefore it belongs to the third hazard class - 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 harvest.
The drug is produced in a water-soluble form, in the form of an emulsion. It's 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 that paralyze arthropods. The latter cannot move, eat and die of hunger.
The substance enters the pest organism in two ways:
- By contact - they penetrate through soft, loose integuments.
- Intestinal - during meals, along with 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 helps
Biological preparation Fitoverm has a detrimental effect on most garden and garden pests. These include:
- Colorado beetle.
- Mole.
- Sawfly.
- Thrips.
- Fruit moth.
- Leaf roll.
- Whitefly.
- Aphid.
- Gall mite.
Strawberries are most often affected by weevils, which gnaw on stems, buds, leaves and berries. The surface of their body is dense, scaly, therefore, with a contact action, the insecticide is powerless. For the poison to reach its target, the insect must eat the processed parts of the strawberry. After 10 hours, the drug takes effect and the weevil can no longer eat.
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.
Slugs love to feast on juicy berries. Their surface is very delicate, therefore, after the Fitoverm solution enters the integument of the pest, the effect occurs already after three hours.
Validity and expectations
The validity period of Fitoverm on strawberries depends on the parameters of the environment.It is more effective at high temperatures than in excessive humidity and cooler weather. On average, the period of protection of a plant from pests after treatment is from five days to two weeks.
The waiting time for the drug is only two days. During the fruiting period, processing is carried out as follows:
- Ripe strawberries are harvested.
- Plants are sprayed with Fitoverm solution.
- The next collection is carried out after three days.
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 chemical agents can no longer be used, since the waiting period (the time from processing to harvesting) is at least three weeks. Fitoverm decomposes quickly, does not accumulate in the stems, therefore it is used at any time during the growing season of strawberries without damage to the soil, plants, bees and humans.
Is it possible to process strawberries with Fitoverm during flowering
It is possible to process strawberries with Fitoverm for several years, since pests do not adapt to the drug and its effectiveness persists for a long time. The product is used during the flowering and fruiting period 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 the 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, windless weather. Depending on the lesion, at least four procedures are carried out - in early spring, during flowering, fruiting and after its end.
How to dilute Fitoverm for processing strawberries
In order to dilute Fitoverm for spraying strawberries, several rules are followed:
- The required dose is dissolved in a small amount of water.
- Mix thoroughly.
- Add water to the volume recommended according to the instructions.
- Prepare a solution immediately before use.
- Use it in its entirety or dispose of the residues after processing.
How to breed Fitoverm from a 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 disconnect, it will be too late - the females have already pierced them and laid eggs on which the drug does not work.
For weevil treatment, you need to dissolve 20 ml of the product in 10 liters of water. The resulting solution is enough to spray one hundred strawberry bushes. They start processing immediately, since 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 a nematode on strawberries
Nematoda are 1 mm long roundworms that live on the roots of strawberries. You can notice that the plants are affected by several symptoms:
- The leaf plates wrinkle.
- The whiskers are shortened and the number of colors is much less than usual.
- The pubescence on the cuttings disappears.
- Red spots appear between the veins.
Fitoverm stops the work of the digestive system of the worms, and they die. The drug can be used in powder or solution. In the first case, it is scattered over the soil surface and buried or added to the holes during planting, spending 18 g of powder under one plant.You can spill the soil under the bushes with an aqueous solution of Fitoverma emulsion - 3 ml per 1 liter of water.
What Fitoverm can be mixed with
It is not recommended to mix Fitoverm with other preparations and fertilizers that have an alkaline reaction. A temporary break in their use should be at least three days.
Without compromising the quality of processing, Fitoverm can be mixed with growth stimulants (Zircon, Epin), organic fertilizers and fungicides. Do not use it with copper-based insecticides and chemicals at the same time. In order to check the compatibility of drugs, they are mixed in small volumes. If liquids stratify or precipitate falls out, they are contraindicated in the complex.
When and how to properly process the berry
In order for Fitoverm's treatment of strawberries after harvest, before 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.
- Observe 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 preparation was diluted to store food.
- If the solution gets into the eyes or on the skin, rinse them with plenty of running water.
Drug analogs
As analogues of Fitoverma, drugs are used, the active substance in which is aversectin C:
- Vertimek - used against sucker, aphids, mites in greenhouses, toxic to bees.
- Akarin - destroys nematodes, valid for four days.
- Gaupsin - destroys fungi by 96%.
- Actellic - aimed at eliminating aphids, scale insects and weevils.
Conclusion
Fitoverm for strawberries is an ambulance for infestation by insect pests. With timely and correct use, the drug will not only get rid of parasites, save the harvest, but also will not harm the soil, beneficial insects and humans.
