Association Policy
Where CSA stands
Two formal positions adopted by the association: on the protection of seed varieties, and on agricultural biotechnology.
Policy 01
Intellectual property, the PVPA, and the “saved seed” provisions.
Policy 02
Safety, labeling, regulation, testing, isolation, and education — in twelve parts.
Policy 01 – Variety Protection
Selling or using seed varieties without the permission of the owner
Consumers who buy seed for planting today are not simply buying a product. They are paying for two things: the cost of the investment, which includes people and capital resources; and the cost of research and development. These activities are necessary to bring any product to market, and without them there would be no advancement of society. A firm invests money in the hope of realizing a profit so it can survive and continue to serve its customers. Without the incentive to realize a return on investment, firms will not conduct research and new products will not be developed.
Seed companies with breeding programs need incentives to conduct research and invest human and financial resources in the development of new, improved seed varieties. The future success of California agriculture depends on this process. CSA supports the rights of owners of protected varieties to realize a profit from their investments in research and development, and urges growers and those in the seed industry to respect those rights. CSA also believes it is in the best interest of agriculture as a whole to abide by the spirit and the letter of the U.S. Plant Variety Protection Act (PVPA) and other laws protecting intellectual property rights.
CSA prides itself on promoting high standards of integrity and ethics within the association membership specifically and within the seed industry in general, and urges the grower community and the public to adhere to the same high standards. Members and others should compete on an ethical and moral basis in the marketplace. They should not look for or employ ways to evade state and federal seed laws, or the ownership protections provided by the PVPA, patent and trademark laws, California trademark, trade secret and unfair competition statutes, or copyright laws, to gain an unethical competitive advantage.
CSA does not condone and is strongly opposed to the practice of using partnerships or joint ventures in an attempt to circumvent the “saved seed” provisions of the PVPA. The law, as interpreted by the Supreme Court of the United States and more recently by the U.S. Congress, permits a farmer or producer of a crop to save seed of a protected variety to plant his or her own holdings. That ruling does not authorize the use of a protected variety to produce a seed copy for propagating purposes separate from the production of that farmer’s crop itself.
The Position
“CSA does not condone and is strongly opposed to the practice of selling seed varieties without the permission of the owner.”

Policy 02 – Agricultural Biotechnology
Producing healthier foods using fewer pesticides on less land
The association’s full position, organized by topic. Open a section to read it; the conclusion sits at the bottom of the page.

Introduction and Benefits
Agricultural biotechnology is impacting agriculture and the general public in positive ways. Through the use of biotechnology, farmers are producing healthier foods using fewer pesticides on less land. Environmental benefits include soil conservation, water conservation, and protection of wild plants and animals.
Many of these benefits are just beginning to come to fruition; the technology promises further nutritional, medical, and environmental benefits in the future. Biotechnology will clearly play a role in reducing world hunger and improving the health of an ever-growing population. It also allows California agriculture to continue leading in agricultural production at a time of intense competition for water supplies and declining available farmland.
Safety
CSA believes that the use of agricultural biotechnology to produce new seed varieties, and to improve existing ones, is as safe as traditional breeding techniques. In fact, the use of recombinant DNA techniques in plant breeding may in some cases be safer than wide crosses or other traditional methods. Biotechnology offers a more precise and more efficient means of developing new plant varieties.
CSA also believes that crops and foods produced through biotechnology are safe and equivalent to similar foods produced through traditional breeding. The federal government and many in the medical and scientific communities agree with this view, and consumers have been safely eating foods and using medicines derived from biotechnology for many years.
Labeling
It is the position of CSA that the Food and Drug Administration already sufficiently regulates the labeling of foods produced through agricultural biotechnology. Where such a food differs from its traditionally bred counterpart in allergenicity, toxicity, or nutritional composition, FDA requires additional testing and labeling to reflect those differences. That requirement adequately protects and informs consumers. Requiring special labeling simply due to method of production is misleading to the public, since these foods are substantially equivalent to and as safe as foods produced through traditional breeding.
Mandatory labels would be tantamount to a warning label and would discourage some consumers from buying these foods; CSA holds that it is improper to place warning labels on foods. CSA also opposes state or local labeling requirements that differ from those established by the federal government — uniform labeling throughout the country is essential to facilitate commerce in food products. Existing seed labeling requirements, along with additional information provided by seed companies, already give growers what they need to properly use biotechnology seed.
Mandatory labeling is not simply a matter of printing additional information on a label. It would require identity preservation from the point of purchasing seed and planting a crop through production, harvesting, transporting, processing, and distribution: segregation of commodities, dedicated equipment and facilities, special cleaning, and documentation and tracking systems — all adding cost. Some commodities, including soybean products, corn, cottonseed products, and wheat, may be used as either food or animal feed depending on market prices, and markets shift in seconds. A commodity may have to be diverted at the last minute from a food market to a feed market with no way to recover the added costs of identity preservation.
Distribution, warranties & tolerances
A recommendation by a seed distributor that a customer purchase a variety of seed — whether produced through traditional breeding or biotechnology — should not automatically be deemed a pesticide recommendation, even where that variety has characteristics of pest resistance or herbicide tolerance. Such a recommendation may be made for a range of agronomic or marketing reasons, and those who merchandise seed have agronomic expertise other agricultural consultants often do not.
Pest control advisors may recommend the use of a seed variety for pest management purposes. However, since a PCA recommendation is not even required to use a pesticide, CSA opposes requiring one in order to sell, buy or use a seed variety — even where such varieties are virus, nematode, or pest resistant, or herbicide tolerant.
CSA believes the advent of seed enhanced by biotechnology should not materially change traditional seed warranties. Those selling seed should warrant and indemnify only up to the value of the seed sold if a problem arises, regardless of how the seed was produced. This position should govern arbitrations and mediations conducted under the mandatory seed arbitration and mediation law in the Food and Agricultural Code.
Tolerances relating to the constituents in a lot of seed or commodity being marketed, if deemed necessary, should be science-based for all seed and commodities regardless of production method. A tolerance suitable for one commodity may not suit another, depending on whether the crop is self- or cross-pollinated, how long the commodity has been in production in an area, and other factors. Allowable tolerances should be based on the quality requirements of the product commodity, not on the methods used to develop the variety.
Regulation, consultation & testing
Mandatory consultation
CSA believes mandatory consultation with the FDA interferes with bringing new products to market that will benefit the environment and the public, and therefore opposes mandatory consultation between FDA and biotechnology companies in gaining approval of new varieties. Agricultural biotechnology foods are among the most tested and scrutinized foods on the market; voluntary consultation has proven adequate and has provided a high degree of protection to consumers.
State regulation
CSA opposes a separate state approval process for varieties developed using biotechnology. The California Department of Food and Agriculture has reviewed these varieties since 1988, and a patchwork of state laws would impede the development and introduction of new varieties.
CSA also opposes planting moratoria on biotechnology commodities, across the board or by individual commodity, which would place California producers at a competitive disadvantage with producers in other states and countries. California should be a leader in this arena, and all California consumers should have the opportunity to benefit from the nutritional and environmental advancements it brings.
Testing
The association supports scientifically validated, accurate, cost-effective, and expeditious laboratory testing for biotechnology traits. Stakeholders should have broad access to testing methods and protocols, and USDA and FDA should provide research funding for test development.
There should be consensus among all stakeholders as to which laboratories, sampling, and testing protocols provide the analyses on which disputes will be settled. CSA opposes biotechnology-free regulations and restrictions imposed by foreign and domestic entities until standardized, accepted laboratory tests are available and there is agreement on who will perform them. CSA also opposes mandatory testing requirements for all commodities; markets and consumers should determine when testing is warranted.
Education, isolation, and stewardship
Education
CSA supports educational programming in agricultural biotechnology and urges the University of California and the Seed Biotechnology Center to continue developing courses and distributing extension materials on the discipline, covering the major aspects of production and distribution of biotechnology commodities in California.
Bio-terrorism
CSA supports increasing penalties for those committing acts of violence in order to thwart the introduction of biotechnology in agriculture and the food industry.
Isolation
In the seed industry it is the responsibility of the seed company to produce in areas that provide adequate isolation, so as to prevent contamination of the seed they are producing. Isolations for ensuring the integrity of crops in production should not automatically be the responsibility of growers employing biotechnology. Issues of isolation, cross-contamination, and related liability should be resolved through the judicial process. In no case should seed breeders or producers be responsible for contamination occurring within production agriculture; such incidents should be resolved by the parties involved in producing the crops.
Identity preservation
Effective identity preservation programs should be developed as needed to facilitate the marketing of both biotechnology and traditionally bred commodities and seed. CSA supports voluntary identity preservation programs offered by entities who wish to provide such services.
Resistance management
Pest resistance management should be carefully monitored by those involved in agricultural biotechnology. Where resistance management is an issue, refugia and other production methods are effective. Determining the necessary procedures for each crop should primarily be the responsibility of the entity developing the variety, in consultation with EPA and USDA, and it is proper for federal agencies to require modifications when warranted by the scientific data.
Conclusion
The use of agricultural biotechnology to develop new, improved varieties of seed offers much to the public by way of more nutritious food, a cleaner and healthier environment, and a more sustainable agricultural industry. Public policy should support and encourage this technology, which has already proved an effective tool to increase agricultural production, reduce pesticide use, and make more efficient use of our natural resources.
