Reviews

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.

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).
