i happened to be one of the successful candidates selected for the Norman Borlaug Fellowship program 2009, in the United States and we were given a very practical examples happening in the states. Please find power point attached for your perusal.
Dear, this process should be gradually inserted into the local culture. Lectures in the local community, encouraging the creation of popular fairs with product samples, materials and publications in the press (releases). The main factor is to link organic food for a healthy life and the involvement of such food as important in relation with the environment. (see more at http://www.danilodeoliveirasampaio.com/tese-de-doutorado/). This is my thesis, which studies on consumer behavior of organic foods in Brazil.
There are numerous examples in the literature of consumer interest (or non-interest) in organic foods. Clearly, "inciting" someone to want organic food (or to do any of a myriad of other things, e.g. lose weight, eat healthier, stop smoking, etc) is not a problem that an individual company can usually change. You can provide perceived positive information about your product (how is it better tasting, healthier, etc) or perceived negative information about other products (full of chemicals, sensory issues, etc). Keep in mind that if you use sensory measures such as "taste" or "flavor", they should be real and fairly consistent since consumers may notice if they are not.
The changes or ability to incite usually come at a societal level - how much does society value the change, but even then as we have seen with smoking everyone will not care.
As others have pointed out, you cannot really get people to do something they are not interested in, but organic is a topic of interest (has societal interest in many countries) so specifically pointing out benefits or negative (of other products) is the best way to get people to "notice" your product unless you have a specific cost, package, etc advantage.
Not sure what you mean by support this. There are many international companies that promote some or all of their products as Organic. Some trade associations, etc promote this through public service announcements and public relations campaigns. If you mean who funds this research or promotion outside their own companies, it is almost exclusively governments, through such departments of US Depart of Agriculture. A few foundations (such as the Organic Farming Research Foundation) provide small grants for targeted research projects, but not to specific producers trying to promote their own products. There may be local money for economic development that one can tap into for companies trying to expand their businesses.
One of the best way for the diffusion of this innovation is to have a platform to sell those products without any intermediates in between. This is a live example executed in my city by a person.
