Biological Products in agriculture

by Bruno Moreira

​Agricultural Biologicals

​Agricultural biologicals are a diverse group of products derived from naturally occurring microorganisms, plant extracts, beneficial insects or other organic matter. They are typically broken down into two or three major categories according to their use in agriculture

​Agricultural Biologicals

The classification varies according to the sources, but we may have:

• Biopesticides​ (or Biocontrols )

• Biostimulants

Making comparisons​

​Comparatives of Superiority and Superlative

​Making comparisons​

Comparative of Superiority: We use -er or more in a structure to compare things:

• ​This product is better for the environment since...

• ​Our product is more competitive than the market average.​

​

Superlative: On the other hand, the superlative shows us the greatest, biggest or most important thing in a comparison. We use -est or most in this case. (Check the sentence itself too for an example!):

• ​The biggest problem we face today is...

• ​We are aware that the most important issue to be tackled is...
