Seed quality is perhaps one of the most important factors in your buying decision.  Quality is what distinguishes Certified Seed from all the rest. Purchasing high quality Certified Seed ensures you that the attributes selected by the breeder are actually present in the seed you purchase.  Seed that carries the Certified tag often costs more than other seed, but you get what you pay for.

In areas of boll weevil eradication, cotton growers have benefited from lower production costs because of reduced pesticide use and higher yields that have led to increased land values and expanded cotton acreage. Pesticide savings between 40 and 90 percent have been realized and many cotton growers have been able to forgo pesticide use entirely. Yield increases of 10 to 20 percent have been achieved in areas where the boll weevil has been eliminated.
