Effect of crude algal extract concentration on the inhibition of Fusarium wilt by F. oxysporum f. sp. lycospersici in tomato seeds.

^aMeans from 20 replicates, each replicate containing 20 seeds

One-way ANOVA tests were performed 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 formulated using surfactant (0.1% Tween 20; v/v).

^dDose of mancozeb as recommended by Sungbo Chemical Company

^eAny two means are not significantly different at the 5% level of significance by Duncans's multiple rang test (Gomez and Gomez, 1984)
