Karbofos refers to a wide spectrum of insecticidal and acaricidal drugs. The composition of the product belongs to the class of organophosphorus compounds and is actively used in the garden.
Karbofos: on the advantages and disadvantages of the drug
The active toxic component of the agent is represented by malathion, the amount of which is ½ part of the total volume. Due to the high concentration of toxin, the chemical acts quickly and with maximum effectiveness on pests in gardening, horticulture and floriculture, as well as is part of:
- "Phenaxin +".
Advantages and disadvantages of use:
- the impact is noted exclusively in the process of direct contact of the sprayed liquid on the insect pest;
- protective insecticidal effect is observed only on fully treated parts of plants;
- short duration of action and quick destructibility under the influence of sunlight, wind and water;
- there is a continuous toxic effect on several types of plant parasites, which often become addictive with regular use.
Dilute the working standard solution in strict accordance with the recommendations specified in the instructions, due to the rather high toxicity of the active component.
Karbofos: pest control
The composition and scope of the tool in horticulture
In agricultural conditions, "Karbofos" is actively used for the rapid and complete destruction of sucking and gnawing insect pests, and is also very effective against plant mites and scale insects. When used in open ground conditions, the drug has a short exposure time, and is also characterized by insufficient resistance to strong winds and water.
The active toxic component of malathion does not have a smell and taste. Field average duration of protective action does not exceed ten days, and in greenhouse soil the duration of active action is a maximum of one week. In the conditions of home gardening, horticulture and floriculture, it is forbidden to mix Karbofos with other types of preparations of chemical origin. Also, you can not spray the product at the stage of flowering or mass formation of ovaries.
Karbofos: instructions for use in the garden
In orchards and garden beds, the product is used to control gnawing and sucking insects represented by tinkerbirds, aphids, caterpillars of the apple codling moth, herbivorous ticks and scale insects, and leaf-eating butterflies. To destroy the larval stage of sawflies and caterpillars on the crowns of an apple tree or pear, it is necessary to adhere to a drug concentration of 0.9%, and the working solution is obtained by dissolving 90 g of Karbofos in a bucket of warm water. When breeding should rememberl, that malathion has thermal and photochemical stability, and is also quite difficult to dissolve in an aqueous medium.
Processing berry bushes represented by gooseberries, raspberries and blackberries, as well as black, white or red currants, requires the use of a different concentration of the active substance. In this case, it is recommended to dissolve 75 g of the drug in a bucket of water at room temperature. Any stone fruit and garden crops should be treated with a standard 0.6% solution. The drug is not capable of exerting a toxic effect on the eggs of plant parasites, therefore, the aerial parts of plants affected by spider mites are sprayed three times, with an interval of one week.
With the help of a solution based on Karbofos, it is possible to effectively combat plant parasites on decorative foliage and flowering crops. A good result is the processing of rose bushes, plantings of lavender, decorative essential oil crops, as well as vines of girl's grapes. Raspberries and berry plantings of garden strawberries from weevil damage are protected by double spraying until the phase of active mass flowering and immediately after the harvest.
The last treatment of fruit plantings with a working solution based on the toxic component of malathion is carried out about a month and a half before the start of mass harvesting. A liquid insecticide is sprayed in the morning or after sunset. You need to choose a calm day. It is best to carry out processing at air temperatures of 15 ° C or slightly lower.
In the process of spraying, the sheet surface should be abundantly wetted from all sides, in order to obtain maximum insecticidal effectiveness and a guaranteed preventive or therapeutic result.
Security measures during processing
For people and warm-blooded animals the drug has an average degree of toxicity and belongs to the third hazard class. Nevertheless, when processing horticultural crops or ornamental plants, it is imperative to follow the entire range of security measures.
When diluting toxic substances and their use in open or protected ground, clothing, rubber gloves and a household respirator are required. After the work done, you need to take a shower, rinse your mouth thoroughly and change clothes. It is forbidden to spray the working solution close to the houses of the bees.
Acute poisoning develops rather slowly. The initial signs of intoxication are the state of oppression and marked inhibition, which after about an hour are replaced by a stage of motor excitement, accompanied by profuse salivation or severe vomiting. A poisoned animal may experience symptoms represented by tremors and clonic convulsions with rapid surface breathing. Despite the fact that malathion is quite well destroyed in the process of heat treatment of food products, it is important to strictly observe the dates of the last processing of plants before harvesting.
Preparations for gardening in the spring
Today, "Karbofos" is almost everywhere quickly replaced by the most modern, and almost harmless to humans pyrethroids, neonicotinoids and diazinone. Nevertheless, drugs based on malathion are still classified as very effective drugs for pest control that have too little sensitivity to other types of insecticides.
