FEATURES OF APHIS FABAE DEVELOPMENT AND BIOCONTROL OF ITS NUMBER ON RED BEET CROPS
Journal Title: Сільськогосподарська мікробіологія - Year 2015, Vol 22, Issue
Abstract
Biological features, population dynamics and harmfulness of Aphis fabae on red beet crops in Ukrainian Woodlands were specified. The degree of phytophag population on red beet of the varieties of different maturity groups and under different seeding terms was detected. The efficiency of biological agents Aktofit 0.2 % emulsifiable concentrate, Bitoksybatsylin (BTU) and insecticide Konfidor water-soluble concentrate was determined. It was detected that the agents reduced the pest population (Bitoksy-batsylin (BTU) by 77.5 %, Aktofit 0.2 % emulsi-fiable concentrate — 77.8 %, Konfidor water-soluble concentrate — 78.7 %) and provided root crop growth by 12 %.
