PETITION: Petition of substance for inclusion on the National List of Substances allowed in Organic Production and Handling Indole-3-butyric acid, IBA To be allowed in ‘Organic Production’ for purposes of plant propagation from cuttings. For use on annual, perennial and woody plants. Application shall be made in enclosed structures. Rates shall be limited to aqueous solution up to 2500 ppm IBA and dry powder up to 0.8% IBA. Page 3 of 33 INTRODUCTION Indole-3-butyric acid (IBA) is a natural substance found in plants. It is used to propagate new plants from cuttings, the most used substance for this purpose. It is effective, and safe to the environment, humans and animals. For commercial use, IBA must be synthesized. A. PETITION IBA is to be allowed in ‘Organic Production’ • Use is limited to plant propagation from cuttings, • All plant types which can be propagated from cuttings can be used: annual, perennial and woody plants. • Rates are to be limited in aqueous solution up to 2500 ppm IBA and dry powder up to 0.8% IBA. • ‘Spot use’ application is to be made in ‘enclosed structures’. Field broadcasting is not allowed. • Solutions are specified to be ‘aqueous’ assuring only water can be used as the solute. B. USES IBA is used, once or few times, at extremely low rates near the time cuttings are taken. It is many weeks or months after application before crops are taken. C. NEED FOR IBA BY ORGANIC FARMERS Plants propagated from cuttings are clonal copies of the mother plant. IBA allows the plant cuttings to produce new roots rapidly. IBA is used to propagate most plants which can be reproduced from cuttings. IBA is used these purposes: 1. Many crops are impossible to root from cuttings, such as bay and rosemary. 2. Crops which are difficult to root, and take a long time to develop roots are under stress susceptible to pathogenic fungi such as Phytophthora. Rapid root formation eliminates stress and allow plants to overcome these fungi. 3. Many seedless crop plants are not available to the organic market such as seedless tomato, cucumber, melon, and squash. Propagation from cuttings using IBA allows growers to produce many kinds of seedless crops like beans, tomato, cucumber, squash, and melon. Propagation from cuttings using IBA yields new plants that are identical to the mother plant.. 4. Many crops can only retain flavor if clonal propagated from cuttings such as mints and basal. Seed propagated basal plant variable flavors; propagation by cuttings using IBA produce exact flavors as the mother plants Page 4 of 33 5. Organic crops that are currently propagated using IBA or TC must be kept one year under organic conditions before being called ‘organic’. IBA on the approved list allows crops to be taken any time after propagation. For example, strawberry and raspberry are sometimes propagated by tissue culture or from cutting using IBA. During the first year of growing under organic conditions they are considered conventional. Propagation using allowed IBA will allow growing under ‘organic’ conditions to be called ‘organic’ any time. D. LONG HISTORY OF SAFETY As a natural substance, IBA has been shown to have no detrimental effect on the environment. Since identification in 1934, IBA has been shown to be safe to humans and the environment. E. ORGANIC PRODUCTION STATUS There are presently no allowed substances with root inducing ability on the NOP National List. Presently, if IBA is used on cuttings, growers must grow plants one year under organic conditions before the crop can be certified ‘organic’. F. QUALITY CONTROL IBA is required to registered with the US EPA for use in plant growing. The US EPA registration requires that all ingredients must disclosed in the Confidential Statement of Formula if over 0.1%. ‘Manufacturing Use’ and ‘End Use’ products have certified disclosed content.

GROWER COMMENTS Jim Walsh Greenhouse Manager Nourse Farms 41 River Road S Deerfield MA 01373 413-665-2658 Norse Farms is a primary plant supplier of blackberry, blueberry, currant, elderberry, gooseberry, raspberry, and strawberry. Nourse Farms uses IBA solutions to propagate plants from cuttings. They tell their organic grower customers to keep their plants one year under organic conditions before calling the crop ‘organic’. Aris Horticulture, Green Leaf Plants division PO Box 230 Barberton OH 44203 330-745-2l43 Aris Horticulture, formerly Yoder Brothers, is one of the largest US suppliers of rooted and un- rooted perennial plant cuttings. Their herb selection includes lavender, metha (mint), slavia (sage), thymus (thyme) , stevia, oregano, rosemary, basal and catnip. Green Leaf uses IBA solutions to propagate plants from cuttings. They sell their rooted cuttings to growers who can take their crop within several weeks after growing our. Green Leaf would like to have IBA on the allowed List since their customers would have a selection of organically produced cuttings which can be sold as organic crops. Cliff Hoogland General Manager Phytotronics Inc 13688 Rider Trail North Earth City MO 63045 314-770-0717 Phytotronics is a primary supplier of materials used by plant growers. They say that they have frequent requests from organic growers for plant rooting products which can be used in organic production. Currently Phytotronics has IBA which is not on the approved List. Phytotronics has a product demand from organic growers which they can not satisfy.

Mark Langan Owner Mulberry Creek Herb Farm 3312 Bogart Road Huron, Ohio 44839 419- 433-6126 Mulberry Creek Herb Farm is a Certified organic grower. They are unable to produce production crops of difficult to root rosemary and lavender. They have very low percentage of rooting of cuttings. They specifically said they require IBA for use in their plant propagation. They also say they are unable to purchase certified organic rooted cuttings.
