Spray tests were carried out on maturity of tomato leaves (Li, 1981), and were divided into four different treatments. Before spraying, the height, stem diameter and leaf area of each plant were measured. Spraying with various concentrations (120 mg.mL-1, 240 mg.mL-1 and 480 mg.mL-1) of garlic bulb crude extract were carried out on the 3rd, 7th,10th and 14th day, and on the 7th and 14th day, we measured the indictors mentioned before again. However, the water was used as control.
