MCGA Approved Products and Prohibited Products

We have been getting a lot of emails and questions about what products are acceptable to use at MCGA.  Since we are an organic garden, we would like products that have been stamped with OMRI (Organic Materials Review Institute) to be our first choice.  Take a look at the products shown below, they all have the OMRI symbol on their labels.  Read all labels carefully and use discretion when applying any insecticide, some kill indiscriminately and thus kill good bugs as well as the bad ones.  If you have questions about acceptable products, feel free to email us at
