He said: "The SUD requires farmers and growers to look at their crop protection methods and asks them to use techniques that minimise the use of chemical products.
"Good reliable biopesticides are therefore set to play an important part in future crop protection. They are coming of age now - more are being registered and their usage will continue to grow as we react to the pressures of the long-term availability of products."
The horticultural supply company saw a record year in profitability and sales in 2010 and appointed three new staff in November, signalling plans for expansion.
Sopp said: "The good year was built on having good people within the business and launching new products. All parts of the business grew last year and with new products and biopesticides, we have seen significant growth."
He was keen to reassure growers of biological products' reliability: "The fact is that biopesticides go through the same registration process as chemical products. We have seen that when used correctly, they provide a very valuable addition to conventional methods."
