Question

Options 1-4 are the different combinations of botanical pesticides. Which combination is a correct representation of the botanical pesticide Cinerin -II
1. Chrysanthemic acid + cinerolone
2. Pyrethric acid + cinirolone
3. Chrysanthemic acid + Pyrathrolone
4. Pyrethroic acid + Pyrethrolone

• A. Option 1 is a correct representation of the botanical pesticide Cinerin -II
• B. Option 2 is a correct representation of the botanical pesticide Cinerin -II
• C. Option 3 is a correct representation of the botanical pesticide Cinerin -II
• D. Option 4 is a correct representation of the botanical pesticide Cinerin -II

Hint:

To remember Pyrethrins chemistry:
Class I esters $\rightarrow$ contain Chrysanthemic acid.
Class II esters $\rightarrow$ contain Pyrethric acid.
Since Cinerin-II is in Class II, it must contain Pyrethric acid + cinerolone.
