Why is not used of water for bioassays tests for search of pesticides in lab? For example we used of acetone as control for bioassay tests in studied of plant essential oils for effect on pest but We do not use of water. Why?
If you used acetone to dissolve the compound you intend to test so acetone is the solvent control in this case. If you used water instead, then your control should be water
Distilled water can be used as control to evaluate all pesticides effects on pests. it provide good comparison between the controls and treatments.
The control used is a medium that is employed for testing of compounds.
Samaneh Mahmoudvand,
In your expeririment you certainly used acetone to disolve Essential oil; so, It is normal for you to use acetone as négative control
In the case where crude essential oil is used in bioassay tests , distilled water should be used as negative control
Conclusion: The negative control in an experiment, depend on which solvent is used to disolve the bioactive ingredients (essential oil, pesticides, extract.....) in Bioassay tests
Hi, everybody
Thanks for your attention
I undestand that based on kind of solvent used in the treatment we used that type of solvent in control.
you may use water for control if your solvent is water even should use a control batch for environmental effects.
