Quality Products

All products surpass the highest quality standards before leaving our plants. They are manufactured to contain high concentrations of active ingredients and only needed carrier. We test everything that goes into the final product, including the shipping containers.


Before a product is added to our line, it must perform and give expected positive results. We use the facilities of leading universities and private laboratories for research rather than having large sums of money tied into capitol facilities. This helps keep our product costs very competitive. Product field testing is completed in commercial operations where such factors as stress, environment, and management changes can effect product performance. All of these factors help assure our products will perform for you.


We are only a phone call, fax, or E-Mail away from our distributors or customers and we offer help where needed. We like to work with people one on one, you won't have to go thru layers of management to get a decision at Brookside Agra L.C. You, our customer, or prospective customer, are the most important part of our service program.
