To preserve cultivated plants from insect pests, gardeners and farmers are forced to use insecticidal preparations. It is important to choose a chemical that will effectively deal with parasites and will not harm the crop. The Shar Pei insecticide is used to combat a wide range of pests that destroy plantings of vegetable, fruit and field crops. Before starting to use the drug, you must read the instructions.
Active substance and release form
An insecticide characterized by contact-intestinal action, contains one active component - cypermethrin, which is part of the chemical class of pyrethroids. One liter of the chemical contains 250 grams of the active substance.
The Shar Pei insecticide goes on sale in the form of an emulsion concentrate, which is packaged in 5-liter plastic canisters. This packaging is intended for farmers sowing large fields. Also on the shelves of gardening stores there are 10 ml bottles and 1.5 ml ampoules for owners of small garden plots.
Principle and range of action
The instructions indicate that the insecticide is intended to combat insect pests of almost all cultivated plants, both in open ground and in greenhouses. "Shar Pei" effectively destroys parasites such as aphids, apple moths, cutworms, leaf rollers and Colorado potato beetles.
The active substance of the chemical, cypermethrin, suppresses the nervous system of insect pests and causes paralysis, as a result of which the parasites die. After 15 minutes after the drug hits the insects, they stop moving, feeding and die. In addition, the active substance disrupts the nutrition of larvae and egg laying.
Since the insecticide is produced in the form of a microemulsion, it instantly penetrates the tissues of the crop plant after application. Thanks to the intestinal contact action, not only adults die, but also larvae and adults. The protective period after treatment is up to 3 weeks.

- Possibility of use even on medicinal plants.
