The present invention relates to a novel oxime ether derivative and a salt thereof, and a fungicide for agriculture and horticulture containing at least one of these compounds as an active ingredient.
This application claims priority based on Japanese Patent Application No. 2008-207297 and 2008-207304, filed on Aug. 11, 2008, and Japanese Patent Application No. 2008-244957, filed on Sep. 24, 2008, the disclosures of which are incorporated herein by reference.
Various agents for controlling diseases of products have been used for preventing disease damage to products in the production of agricultural and horticultural crops, but these are not necessarily satisfactory from the viewpoints of insufficient effectiveness on pests, restriction on their use due to the emergence of disease-causing germs resistant to the agent, phytotoxicity or causing contamination to plants, and toxicity or environmental effects in regard to humans, livestock or fish. Accordingly, there is an increasing need for emergence of chemical agents which reduce these disadvantages and can be safely applied.
