Distribution of cutworms in vegetable crops, their harm and the effectiveness of insecticides tested against them

Abstract

In this article, from the tunnels that infect the underground part of vegetable crops: turnip moth (Agrotis segetum Den.et Schiff), cut worm (A. exclamationis. L.), turn black-C (Xestia c-nigrum L.), wild turn (Euxoa agricola V.), gamma turn (Mamestra suasa Schiff.), tobacco turn (Agrotis obesa B.) and epsolon turn (A. ipsilon Rotl) encounter was detected. Underground cutworms damage to tomatoes is estimated at 6-10% in Navoi, Bukhara and Khorezm regions, 12-20% in the Republic of Karakalpakstan and Surkhandarya, Jizzakh and Syrdarya regions, and 20% in other regions such as Samarkand, Kashkadarya, Andijan, Fergana and Namangan. Up to 31% of underground tunnels were found to be damaged. The damage of the aboveground part cutworms was determined by 18% in Navoi, 15% in Jizzakh, 15-18% in Bukhara and Khorezm regions, 12-15% in Sirdarya, Surkhondarya, Karakalpakstan, 25-30% in the remaining regions. Against worms of months in tomatoes, Deltasis, 2,5% concentration of emulsion (deltametrin), 50% concentration of emulsion in Kurarfon (Profenofos) and Torpedo Jet, 14% soluble powder (Indoxicarb+emamectin benzoate), 2,5% concentration of emulsion in Defentox (deltametrin), when their preparations were tested, 87-93% efficiency was achieved. Contraindications: the drug Kapito 9,3% suspension concentrate (Chlorantraniliprol) is used on the account of 0,45 l/ha to 89,5%, the drug Emafos 42% soluble powder (emamectin benzoate +chlorpyrifos) to 0,6 l/ha. When used on account of 91, 3%, Koragen, 200 soluble powder (chlorantraniliprol) preparation, when applied to 0,2 l/H, 91,6% efficiency was achieved
