Cotton is one of the main agricultural crops sown in Uzbekistan. As is known, over 1.3 mil. hectare of arable land in the Republic. In this regard, the integrated protection of crop plants is becoming increasingly relevant. In solving the problems of increasing the yield and productivity of cotton, plant protection plays a special role. As elsewhere in the world, in Uzbekistan, agricultural plants are damaged by many pests, which cause great economic damage.
