PESTS ON ANNUAL LEGUME CROPS AND POSSIBILITIES FOR CONTROL IN BIOLOGICAL PRODUCTION
Published: 18 Sep 2021
Abstract: Biological production of legume crops is becoming more widespread in many countries, with research aimed at increasing yields and improving product quality. Legumes are an important element of agrotechnical approaches in biological systems. They are a suitable precursor for a various vegetable crops and are actively involved in crop rotation. Annual legumes are attacked by many pests, which at high densities can compromise the yield. Experiments to determine the effectiveness of biological plant protection products to control the main pests on beans and peas grown in a certified organic field were conducted at the Maritsa Vegetable Crops Research Institute, Plovdiv during the period 2019-2020. The tested pests were: black bean aphid (Aphis fabae Scop.), pea aphid (Acyrthosiphon pisum Harris), bean weevil (Acanthoscelides obtectus Say), pea weevil (Bruchus pisi L.), pea moths (Laspeyresia nigricana Step. and Laspeyresia dorsana L.) and twospotted spider mite (Tetranychus urticae Koch.). Tested products are: Piretro Natura EC 75 ml/da (a. i. pyrethrins), Neem Azal T/C 0.3% (a.i. azadirachtin), Naturalis 100 ml/da (a. i. Beauveria bassiana), Dipel 2 X 100 g/da (a. i. Bacillus thuringiensis var. kurstaki strain ABTS) and Rapax 100 ml/da (a. i. Bacillus thuringiensis subsp. kurstaki, strain EG 2348).
