Abstract

In order to evaluate the effect of garlic extract to induce break dormancy in pear trees under low chilling conditions an experiment was installed in a 7-year-old ‘Housui’ pear commercial orchard located in Campo Largo, PR, presenting tree spacing with 1,5 m between plants x 4,0 m between rows. The treatments were applied when plants were in the B (swollen bud) phenological stage which happened on 08/17/2008. A completely random experimental design of 6 treatments with 3 replications was used. Treatments were: 1) Control; 2) 4% Mineral Oil (MO); 3) 0.52% hydrogen cyanamide (HC) + 4% MO; 4) 1% Garlic Extract (GE) + 4% MO; 5) 2.5% GE + 4% MO; and 6) 5% GE + 4% MO. The evaluations were performed 29, 36, 43, 50 and 57 days after product application. Garlic extract exerted influence on break dormancy of the pear buds. Treatment with 5% GE + 4% MO anticipated bud burst, presented similar results to those obtained with 0.52% HC + 4% of MO. No treatment was toxic to the plants.
