Microbiolização e peliculização: efeitos sobre a qualidade fisiológica e sanitária de sementes de soja

Abstract

This work aimed to evaluate the microbiolization and film-coating about the physiological and sanitary quality of soybean seeds. Treatments were arranged in factorial scheme 2 x 9 (cultivars x seed treatments). The cvs. Used were NS 5959 IPRO and BMX Vanguard IPRO. Seed treatments evaluated were: T1) Trichodel® (Trichoderma spp.); T2) Trichodel® + polymer (Polyseed CF®); T3) Trichodermil 1306 SC® (Trichoderma harzianum); T4) Trichodermil 1306 SC® + polymer; T5) Rizolyptus® (Bacillus subtilis); T6) Rizolyptus® + polymer; T7) Standak® Top; T8) Standak® Top + polymer; T9) Witness (withou recoating). Tests were performed on the sanity, germination, seedling length. The experimental design used was completely randomized (DIC), whit four repetitions. For the evaluation of sanity, the treatments whit fungicide, alone or in combination whit the polymer, presente the lowest incidence of fungi. Already the best index of germination was obtained in treatment on the basis of Trichoderma spp. and Bacillus subtillis for cultivars NS 5959 and BMX Vanguard, respectively.
