e3“This study, therefore, investigated the in vivo antibacterial activity of ethanolic and hexane extracts from Tithonia diversifolia against R. solanacearum in tomatoes”
e4“In vivo greenhouse experiments revealed that ethanolic extracts of T. diversifolia gave a percentage disease severity of 24 ± 2.6% in the leaves”
e5“32 ± 3.1 % in the flowers as compared to metham sodium (positive control), which gave a disease severity of 16 ± 2.2 % (p ˂ 0.01)”

Other claims from this paper (3)
- Intervention effect Ethanolic extracts of T. diversifolia gave higher disease severity on tomato flowers than metham sodium, 32% against 16%.
- Observation Ethanolic extracts of T. diversifolia had the highest extraction yield, 2.8 ± 0.22% w/w.
- Recommendation T. diversifolia ethanolic extracts are proposed as efficient, cheap and potent biopesticides for effective control of R. solanacearum in tomato.
