RHIZOBIUM TROPICI NODULATION PERFORMANCE IN THE TREATMENT OF SEEDS WITH FUNGICIDES, INSECTICIDES AND POLYMERS IN BEANS

Abstract

THE OBJECTIVE OF THIS WORK WAS TO EVALUATE THE PERFORMANCE OF THE NODULATION OF RHIZOBIUM TROPICI IN THE TREATMENT OF SEEDS WITH THE CHEMICAL PRODUCTS AS FUNGICIDES, INSECTICIDES AND POLYMERS USED IN THE TREATMENT OF SEEDS IN THE COMMON BEAN CROP. SEVEN TREATMENTS WITH 4 REPLICATES WERE CARRIED OUT IN 8 KG POTS. THE EXPERIMENTAL DESIGN WAS RANDOMIZED BLOCK, THE DATA WERE COLLECTED IN THE FLOWERING PHASE (R6) AND MATURATION (R9), SUBMITTED TO ANALYSIS OF VARIANCE AND THE MEANS COMPARED BY THE TUKEY TEST AT 5% PROBABILITY. CONCLUDING THAT THE CHEMICAL TREATMENTS (INSECTICIDES AND FUNGICIDES) USED IN THE TREATMENT OF SEEDS DID NOT INTERFERE IN THE PRODUCTION OF GRAINS. THE USE OF THE POLYMER AS A SEED FACTOR DID NOT INTERFERE IN THE INFECTION PERFORMANCE AND NODULATION OF RHIZOBIUM TROPICI TO THE COMMON BEAN. THE TREATMENTS T.RT + P + CT (CARBENDAZIM + TIRAM), T.RT + P + IT (IMIDACLOPRID + THIODICARB) AND T.RT + P + T (THIAMETOXAM) HAD A NEGATIVE INFLUENCE ON THE NUMBER OF NODULES PRODUCTION, BUT NOT IN THE PERFORMANCE OF BNF IN THE COMMON BEAN CROP.
