摘要:
Compounds having the formula (I) ##STR1## [wherein: R.sup.1 and R.sup.2 are each alkyl or halogen, or they are trimethylene or tetramethylene; R.sup.3 is hydrogen or alkyl; A is alkylene; and R.sup.4 is optionally substituted phenyloxy or benzyloxy substituted with at least one alkyl, halogen, alkoxy, alkylthio, alkenyl, trifluoromethyl or nitro; optionally substituted phenyl substituted with one or two halogen atoms, alkyl or alkoxy; furyl or thienyl] and their salts.
摘要:
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.
摘要:
Agricultural fungicidal compositions containing as an active ingredient one or more 4-aminoquinazoline derivatives. The amino group is substituted, e.g., with a phenoxyalkylene, and the quinazoline nucleus may be substituted at 2- and or 6-positions.
