Treatment of strawberries with Karbofos: in spring, autumn, after harvest

Karbofos for strawberries is in demand both among gardeners and plantation owners. The effectiveness of the drug depends on the concentration of the solution and the correctness of its use.

Characteristics and effect of the drug

Karbofos is an acaricidal and insecticidal agent classified as a class of organophosphorus compounds. The drug has a wide spectrum of action: it is also used in agriculture, it helps in the fight against various pests. In medicine, Karbofos is known as a means for sanitary and household disinfection.

The active ingredient of the drug is the component malathion. It is a colorless liquid with an unpleasant odor similar to a thiol. To the touch, Karbafos in undiluted form has an oily structure. Diethyldithiophosphoric acid is present as impurities.

Malathion is slowly hydrolyzed in water and is thermally stable, but when mixed with acid it transforms into a more active form - malaoxone.

The first developments of Karbofos belong to academician Arbuzov, who received the prototype of the modern drug in the 20th century

The insecticide has an enteric-contact action. When it enters the digestive system of an insect, Karbofos poisons it. Complete death of the pest occurs after 3-4 hours.

If you treat strawberries with Karbofos several times in the fall, spring and summer, its effectiveness is significantly reduced. This is due to the fact that insects, in response to poison, produce an enzyme that neutralizes harmful substances. It is recommended to process 2-3 times a year.

Advantages and disadvantages

There is a significant variety of insecticides on the market, but Karbofos has a number of advantages:

  • efficiency (destroys most pests after initial treatment);
  • remains effective for two months;
  • capable of killing bedbugs at any stage of development;
  • affects ants, cockroaches, fleas;
  • Available in stores in various dosage forms (emulsion and powder).

The only significant drawback when treating strawberries against pests with Karbofos is the presence of a strong toxic odor that can persist for several months. Under the influence of environmental factors, the insecticide quickly disintegrates: outdoors after ten days, in a greenhouse after a week.

Application area

The drug is widely used in agricultural production and in the forestry industry for disinfection work.The chemical is also popular among warehouse owners who want to protect their supplies from pests.

In the agricultural industry, the insecticide effectively kills aphids, spider mites, copperheads, bedbugs, whiteflies and ants.

Karbofos fights not only pests, but also pollinating insects

Is it possible to treat strawberries with Karbofos?

This crop needs protection throughout the growing season. Karbofos can be sprayed on strawberries in autumn and spring. To achieve maximum effect, you should follow the instructions for use.

How to properly treat strawberries with Karbofos

All work must be planned in advance. Prepare equipment, utensils, and tools. Weather conditions, the volume of cultivated area, and time of year should be taken into account.

The optimal air temperature for processing strawberries is 12-25 °C. When these values ​​increase or decrease, the effectiveness of the drug noticeably changes for the worse.

To prepare the solution, it is best to use water with neutral or slightly acidic acidity. If the pH is above 7, then Karbofos may partially lose its properties. You can use citric acid to acidify the water. To do this, it is enough to dissolve 3-5 g of the substance in 10 liters of water. If acetic acid is available, then you need to add 5 ml of 9% essence to 10 liters of water.

The optimal liquid temperature is 10-16 °C. Gardeners often prefer water from open reservoirs or wells. In this case, you need to dial it in advance and let it settle and warm up. Karbofos dissolves less well in cold water. If the liquid is preheated, it will lose some of the oxygen.

When preparing Karbofos solution, it is forbidden to use food containers: it is better to give preference to special containers

Rules for working with insecticide when spraying strawberries:

  1. The procedure must be carried out either before the appearance of pests, or at the height of their activity, but before reproduction begins.

  5. The optimal time for work is in the evening, when the activity of most insects is significantly reduced, and the drug, due to temperature changes, will stay longer on the leaves in the form of drops.
  6. Do not process strawberries during rain or strong winds. If bad weather occurs after the procedure, irrigation should be repeated under more favorable conditions.
  7. The prepared solution cannot be stored; it must be used immediately. The duration of work should not exceed an hour. Dispose of the remaining solution.
Warning! You cannot use drugs that do not have manufacturer’s markings, expiration dates, or labels. If storage rules are violated, it is recommended to dispose of Karbofos.

Reviews about the drug Karbofos

Ignatieva Ekaterina, Buzuluk
An annual problem in our area is ticks. They attack strawberries and cause significant damage to the crop. The first time I purchased the drug on the advice of a consultant, diluted it, sprayed it and did not see any results. Only later did I find out that in the heat and rain you can’t irrigate strawberries: the drug quickly decomposes. When treated again, the mites disappeared the next day.
Gromova Valentina, Novokuibyshevsk
I grow strawberries in a greenhouse, so I have to treat them for pests twice a season. Karbofos has never failed: it acts quickly, decomposes in ten days, and destroys both larvae and adults. A significant drawback is the unpleasant odor and toxicity of the product.But in five years of use I have never encountered any side effects; you just need to protect your skin and mucous membranes with gloves and goggles.
