Efficacy of Plant Materials in Controlling Aphids on Okra (Abelmoschus esculentus L. Moench) in Limpopo Province of South Africa
Round 1
Reviewer 1 Report
First of all I think this paper worth publishing after review.
Several methodological issues needs to be explained a bit more exactly.
- How plots with different treatments were isolated from each other?
- Aphids abundance assessment by visual scanning and rating seams a bit out of scientific assessment. A simple picture made and counting from a PC using picture would be more exact. I don’t understand how the mortality rate were then assessed, so the effect or each extract and insecticides has to be explained or reevaluated.
- What was the post-hock test used for data analyses
- Results has to be presented more clear, treatments and control were different from each other at 95% level are given. But several treatments were used, so please explain exactly what the results are.

Reviewer 2 Report
This is overall a well written and carefully documented study which is of value for future farming strategies.In the introduction lines 36-48 it does not harm to mention studies in biological pest control using infected pests and/or pest enemies:
