Protecting cultural plants from pests is a very important component of the entire cultivation process. Crop losses from the negative influence of various kinds of insects sometimes reach 15-17%, and in some cases up to 35-40%. This, in turn, significantly affects the profitability of the agricultural economy. The ADAMA company, founded in Israel, has developed an insecticide and acaricide in one product - Pyrinex (Pyrinex urk.), for high-quality protection of plants from a fairly wide range of harmful insects, including mites.
The main qualities of Pyrinex
The product has a high degree of protection, and against some insects it has an absolute, quick and prolonged effect and universality in use. This is an organophosphorus insecticide, which, in addition, has an excellent fumigation property. Thanks to the abilities listed above, Pyrinex works perfectly in hard-to-reach conditions, which makes it possible to control not only a wide list of standard harmful insects, but also to control ticks. The versatility of the product concerns both the spectrum of action and the list of cultivated plants that can be treated with Pyrinex and the time of spraying, or rather, weather conditions. The temperature mode of application of the drug allows you to use it in early spring, in relatively cold weather conditions, during the emergence of insects from hibernation (diapause), and even in summer, during the period of extensive cultivation of pests. The insecticide is able to maintain good activity for 14-28 days after use, and the first traces of its influence are noted after a few minutes.

Mechanism and spectrum of action
The active ingredient of Pyrinex is chlorpyrifos. A substance that is a contact, intestinal and fumigation insecticide. Penetrating into the organism of the pest, it blocks the transmission of nerve impulses by disrupting the activity of acetylcholinesterase. As a result, the visible manifestation of the effect of the insecticide is tremors - convulsive muscle movements and subsequent paralysis of the insect. Pyrinex effectively protects crops from a wide range of harmful insects. These are representatives of Lepidoptera, Coleoptera, Diptera, Homopterous, Orthoptera, as well as bugs (Heteroptera) and ticks (Acari). The powerful fumigation effect allows you to control even such pests that live secretly. Pyrinex is one of the best drugs that copes with the grape leafhopper, as well as with other main biting and sucking insects harmful to cultivated plants.
Tips for using Pyrinex
After using the drug for spraying cultivated varieties, mechanical work is permissible after 4 days, and manual work after 10. Regarding the spraying of pastures and wild vegetation, it is not desirable for people to be in the areas where the insecticide was applied for 30 days.
collection of mushrooms, as well as
berries is not allowed for the entire processing period. For maximum results, the product should not be applied at a temperature below 8⁰С or if frost is expected. Past precipitation immediately after spraying can reduce the effectiveness of Pyrinex to some extent. The product is toxic to bees. The average consumption of working fluid per crop is 200-400 l/ha. When spraying apple trees, this rate increases to 800-1500 liters per 1 ha, and
grapes 800-1200 l/ha. If all the manufacturer's recommendations are followed, it is possible to achieve maximum protection of the crop with minimal harm to the environment.
