The consumption of the prepared solution is up to 2 liters for a currant or gooseberry bush, a young apple tree and about 5 liters for an adult fruit tree.
The preparation of a working solution for treatments in the garden does not depend on the type of culture (currant or apple tree), but on the type of pest:
- against aphids, thrips, Colorado potato beetle and other pests, 1 tablet is diluted per 10 liters of water, spraying during the growing season
- from moth, leaf rollers (leaf-eating caterpillars): 1 tablet per 10 liters of water, spraying during the growing season
- against the weevil, 1.5 tablets are diluted per 10 liters of water, spraying during the growing season
- against whitefly, 2 tablets are diluted per 10 liters of water, spraying during the growing season
- against currant and stem flies on raspberries: 1 tablet per 10 liters of water, sprinkling before flowering and after harvest
Inta-Vir at home
Preparation of a working solution for home treatments: 1 tablet is diluted per 10 liters of water, used for spraying on a leaf. To kill cockroaches, 1 tablet is diluted with 0.5 liters of water.
Spray indoor plants when pests are detected. It is best to use a kitchen scale accurate to the gram and divide the tablet into 8 parts, take 1 g per 1 liter of water. It is enough to spray 2 windowsill of flowers.
Despite the manufacturer's statement that cypermethrin does not cause resistance, there are factors that weaken its effect. Pyrethroids (including cypermethrin), entering the body of insects, are subject to the action of oxidative enzymes and enzymes that hydrolyze ester groups (esterases). The action of esterases leads to the splitting of the original molecule into acidic and alcoholic components and, as a consequence, to a complete loss of insecticidal activity (Tkachev A.V. Pyrethroid insecticides - analogs of natural protective substances of plants. Sorovsky educational journal, volume 8, No. 2, 2004).
Apparently it is this property, as well as the poor wettability of the leaves, that explains the incomplete destruction of pests. Therefore, for indoor flowers, spraying can be replaced by dipping leaves in a bucket of solution. It is permissible to increase the concentration by 2-3 times (2-3 tablets per bucket of water). Waiting periods - validity time up to 20 days.
It should also be noted on Inta-Vir a positive point - the absence of a poisonous smell, of the minuses: the drug is easily washed off with rain.
Recommendation iplants.ru: in view of the manufacturer's dubious statement that pests do not have resistance to the Inta-Vir drug, use it for the garden no more than 2 times per season, and also alternate with drugs of another group (according to the active substance) by years, t That is, use Inta-Vir at their summer cottage in a year.
The drug diluted in containers under the influence of the sun, temperature and humidity completely decomposes within a month. When applied to the soil, it lasts for 2-3 weeks in light soils and up to 10 weeks in heavy soils. When sprinkled on the surface of the soil (in the grass) it lasts for 2 weeks.
Cypermethrin is highly toxic for bees and other beneficial insects (1-2 hazard class, the size of the protective zone for bees is 4-5 km, the duration of the limitation of the summer of bees is 96-120 hours). Highly toxic to fish, moderately toxic to humans and warm-blooded animals (hazard class 2-3).
