Foliar application of carvacrol on disease severity of bacterial spot, plant vigor and yield of tomato in the field.

Treatment	Early Blight (%) ^zw	Bacterial Spot (%) ^zw	Vigor ^yw	Yield of Extra and Large Fruit (kg/plant) ^xw	Yield of Total Fruit (kg/plant) ^xw
Untreated control	38.1 ^a	6.9 ^a	3.2 ^b	0.67 ^b	1.65 ^b
Carvacrol @ 0.5 mM	32.0 ^b	2.4 ^b	4.3 ^a	1.23 ^a	2.13 ^a
Carvacrol @ 1.0 mM	30.6 ^b	3.5 ^b	4.5 ^a	1.27 ^a	2.22 ^a

^z Disease severity of early blight (Alternaria tomatophila) and bacterial spot (X. perforans) was recorded as the percentage leaf area of the whole plant with symptoms of each disease. ^y Vigor of the plant was rated based on a 1-5 scale: 5= vigorously growing; 4 = slight yellowing and a little short; 3 = more yellowing and shorter; 2 and 1 = growing very poor than normal. ^x Tomato fruit were harvested from each plant and fruit size was graded as extra-large, large, and medium. ^w Means followed by the same letters in each column were not significantly different at P = 0.05.
