Effect of algal extract formulation on the inhibition of F. oxysporum f. sp. lycospersici in tomato seeds 14 days after treatment.

^aMeans from 20 replicates, each replicate containing 20 seeds.

One-way ANOVA tests were applied to determine significant differences among the treatments. Correlation coefficients among the experiments were analyzed using SAS Systems v. 8.12 (SAS Institute Inc., Cary, NC).

^bFusarium oxysporum f. sp. lycospersici at the concentration of 500 spores/seed

^cAlgal extract at the concentration of 150 µg/seed formulated using methanol, zeolite, or surfactant (0.1% Tween 20, v/v) as vehicles.

^dMancozeb at the recommended concentration of 200 µg/seed.
