Pesticide products containing spores of this active ingredient can be used on various fruits, vegetables, and ornamental plants in greenhouses and outdoors. There are no expected adverse effects on humans or the environment when the products are used according to label directions. For commercial use, producers grow the fungus Ampelomyces quisqualis isolate M-10 in a liquid nutrient mixture, and then collect and dry the spores. The spores are stored as a dry powder. They are mixed with water to reactivate them, and then the mixture is applied to crops.
Application is permitted throughout the growth cycle, including the day of harvest.
Based on required toxicity tests, no risks to humans are expected from handling or eating food containing small amounts of Ampelomyces quisqualis isolate M-10. Applicators are instructed to use appropriate protective equipment, including a respirator to minimize their inhalation of dust or mist. However, it is not allowed to be applied directly to water or be used in ways that could contaminate water. As of February 2000, there was one registered pesticide end product using this active ingredient.
