Fig. 1. In vivo effect of compost teas made from chicken, sheep, and cow manure, and from shrimp and seaweed composts on necrotic tomato seedlings inoculated with Pythium ultimum. Means with the same letter are not significantly different (P = 0.05) according to Fisher's protected LSD test.

Fig. 2. In vivo effect of compost teas made from chicken, sheep, and cow manure, and from shrimp and seaweed composts on fresh weight of tomato seedlings inoculated with Pythium ultimum. Means with the same letter are not significantly different (P = 0.05) according to Fisher's protected LSD test.
