  • 4-Aminoquinazoline derivatives having fungicidal, anti-insect and acaricidal properties
    Patent number: 4304778
    Abstract: 4-Aminoquinazoline derivatives of formula (I): ##STR1## (wherein: R.sup.1 represents an alkyl group, a cycloalkyl group, an alkenyl group or a benzyl group;R.sup.2 and R.sup.3 are the same or different and each represents a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom;X represents a straight or branched chain alkylene group; andn is 0 or 1)and salts and hydrates thereof are valuable fungicidal, anti-insect (insect-repellent and insecticidal) and acaricidal compounds and thus can be used to treat or prevent many diseases affecting agricultural and horticultural plants, while, at the same time, having a much lower toxicity to fish than is exhibited by other known compounds.
