Insecticides based on insect chitin synthesis inhibitors

详细

The following benzoylurea chitin synthesis inhibitors—diflubenzuron used in Dimilin and Gerold formulations, lufenuron registered as Match, and a Lufox combined insecticide based on two active ingredients, lufenuron and fenoxycarb (juvenoid)—have been tested. The effectiveness of the Dimilin insecticide in regulating the codling moth (Cydia pomonella L.) population was assessed in Tambov oblast, Rostov-on-Don oblast, and Krasnodar krai in 2010–2011. Reduction of damage in the harvested fruit at the maximum application rate comprised 90–100% in all the regions. The biological effectiveness of the Gerold preparation in regulating the complex population consisted of leafrollers and currant bud moths (Incurvaria capitella Cl.) and comprised 85–87% in the Tambov oblast and reached 100% in the Orel and Leningradskaya oblasts (2012–2014). The field tests to assess the biological effectiveness of the Match insecticide in regulating the population of cotton worm (Heliothis armigera Hb) in Krasnodar krai and Astrakhan oblast proved that the preparation was capable to reduce the number of the cotton worm larvae on tomato plants (up to 99.0%). The Lufox combined insecticide effectively reduced the larval population of codling moth and, hence, the damage of apple fruit in Krasnodar krai and Rostov-on-Don oblast (up to 96.8%). The tested plant protection products are recommended for use in the ecologized systems.
