This study was conducted to evaluate the effects of commercial formulations of the biopreparate (BP) applications on vegetative development of potted grafted grapevine plants. Two biopesticides (T22 planter box (Trichoderma harzianum Rifai KRL-AG2) and T22-ERS (Trichoderma harzianum Rifai KRL-AG2+endo mycorrhiza)) and biostimulant (Disperroot, DR) were tested in the study. Potted grafted saplings of Royal cultivar grafted on 1103P, 110R, 5BB, 1613C and Ramsey rootstocks were used. The T22, T22-ERS and DR were applied to grafted and potted young plants. Grafted and potted young saplings were grown in open areas. The shoot and root growth parameters were determined at the end of vegetation period. The effects of BP treatments on shoot and root parameters of young vine saplings varied with the treatments and rootstocks. DR treatment generally had positive effect on shoot and root growth parameters of young saplings. DR treatments were recommended for better growth and development of young vine saplings.
