All applicable directions, restrictions, and precautions on the U.S. EPA registered label for Topsin M 70WP Fungicide (EPA Reg. No. 4581-403, 73545-11 or 73545-11-82695 ) and these use instructions label must be followed. These use instructions must be in the possession of the

Tank mixing with other compatible pesticides, spray adjuvants and fertilizers is allowed as long as all labeling and regulatory requirements are met and tank mixing is not otherwise prohibited. The Department shall be immediately informed of any adverse effects resulting from the use of this exemption. Please note: The U.S. EPA expects concerned growers or grower groups to work towards the registration of use patterns that may be needed on a continuing basis. It will, therefore, be necessary to require applicants wishing to renew emergency exemptions to provide a progress report on residue tolerance and registration along with request for re-issuance of an emergency exemption. Without substantial progress in pursuing a tolerance and registration for the use in question, it will be difficult to obtain an emergency exemption for another season. The pesticide manufacturer or Western Region IR-4 may be contacted regarding the initiation of a pesticide petition for residue tolerance. A final report must be submitted by the county agricultural commissioner to the Pesticide Registration Branch, Department of Pesticide Regulation within 45 days of the expiration date of this exemption. This report must include the following information:
Prior to use under this exemption, a permit must be obtained from the county agricultural commissioner. The permit shall state the maximum number of acres to be treated, maximum amount of product that may be applied, and dealer from which the product may be purchased. The purchaser (permittee) or purchaser’s (permittee’s) agent must provide the seller, or person delivering the restricted material, a copy of the permit on the date the restricted material is delivered. The dealer shall maintain a record of each sale which shall be made available to representatives of the Department of Pesticide Regulation or county agricultural commissioner upon request. Such records shall include the date of sale or delivery, permit number, identity and amount of product purchased, and the name of the purchaser. All applications of this material shall be made by or under the supervision of a certified applicator certified for this category of pest control. Agricultural pest control businesses shall submit a pesticide use report to the county agricultural commissioner within seven days of each treatment. Growers who apply this material shall submit a pesticide use report to the county agricultural commissioner by the 10th day of the month following the month in which the applications are made. The county agricultural commissioner in cooperation with the Department of Pesticide Regulation, will monitor the use of the product under this exemption and will prepare a written report describing any unusual or adverse effects attributable to this use. This exemption does not constitute a recommendation of the Department of Pesticide Regulation and will not prevent quarantine action if illegal residues are found in or on any crop. To the extent consistent with applicable law, neither the Department nor the county agricultural commissioner, manufacturer or the formulator makes any warranty of merchantability, fitness of purpose, or otherwise, expressed or implied, concerning the use of a pesticide in accordance with these provisions. The user and/or grower acknowledge the preceding disclaimer.
