As a study target, the effect of bacterial bioformulates on the control of R. similis and enhancer on the development of banana seedlings cultivar Williams was evaluated. Five study factors were used: Three bioformulates made with different components, which were inoculated in combination with 4 strains PGPRs Acinetobacter calcoaceticus BMR 2-12, Serratia marcescens PM 3-8, Pseudomonas protegens CHA0 and Enterobacter asburiae PM 3-14; Nematicide and Without PGPRs for their biocontrol and promoter evaluations in the presence of the nematode applied in initial populations between 10,000-15,000 plus four repopulations of 8,000–10,000 in banana seedlings. The biocontrol factor of Bioformulated-1 with CFU/mL-1 loads of 9.70X109 obtained greater effectiveness in the presence of R. similis, reducing to 1, 000/100 g of root, counteracting its incidence of damage to 12.28 %. Likewise, the effect of the Bioformulated products improved various plant growth parameters, involving an increase in plant height with 42.74 and 42.42 cm (Bio-1 and 3); greater number of leaves of 5.80 and 5.40 (Bio-1 and 2); root length with 35.64 cm (Bio-3), revealing to have high benefits towards sustainable agriculture. |
