ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to novel thiazole derivatives, which have insecticidal and acaricidal activity. The preparation and use, in agriculture and horticulture, of agrochemical compositions containing these novel insecticidal thiazoles are also disclosed.
2. Description of the Related Art
It is known in the art that certain thiazole derivatives such as those disclosed in U.S. Pat. Nos. 4,199,506, 4,284,426, 4,371,389, 4,437,875 and 4,437,876 have herbicide antidote properties and in Japan Kokai Koho 06-25199 have fungicidal properties. Furthermore, it is known in the art that UK patent application GB 2331748 discloses 5-cyano or thiocarbamoyl thiazole derivatives and their use as insecticides, acaricides or nematocides. The present invention concerns the novel thiazole derivatives which have excellent insecticidal and acaricidal activity.
