Table 1.

Toxicities of tetramycin and chitosan against B. dothidea and Phomopsis sp.

Pathogens	Antibiotic Bactericides	Regression Equation	Determination Coefficient (R²)	EC₅₀ (mg kg⁻¹)
Chitosan > B. dothidea	0.3% Tetramycin AS	y = 6.0759 + 1.2511 x	0.9963	0.14
Chitosan > B. dothidea	Chitosan	y = 5.1568 + 0.7069 x	0.9941	600.11
Phomopsis sp.	0.3% Tetramycin AS	y = 1.1510 + 9.3601 x	0.9968	0.09
Phomopsis sp.	Chitosan	y = 5.2904 + 0.9250 x	0.9865	485.41

x and y indicate the tetramycin (or chitosan) concentration and inhibition rate, respectively.
