摘要:
A known antibiotic, SF-1293 substance and salts thereof have now been found to exhibit high herbicidal effects against a wide variety of herbaceous and woody plants, but they are non-phytotoxic particularly to a useful woody plant, Chamaecyparis obtusa. The herbicidal effects of these SF-1293 substances can be synergistically enhanced by applying in combination with herbicides selected from Linuron, Monolinuron, Monuron and Diuron each known as herbicides of urea derivative class.
摘要:
2-Amino-4-(hydroxy)(methyl)phosphinoylbutyric acid, which earlier nomenclature referred to as 2-amino-4-methylphosphinobutyric acid or its metal salts, or acid-addition salts thereof are used as perennial weeds and brush controlling agents. The L-isomer is twice effective than the racemic acid. The perennial weeds and brush controlling effect may be obtained by foliar application over a prolonged period and maY be surprisingly enhanced by using the compound with a herbicide or synergist selected from the group consisting of choline salt of maleic hydrazide, a phenoxy series herbicide, a benzoic acid series herbicide, 2,3,6-trichlorophenylacetic acid or a salt thereof, (3,5,6-trichloro-2-pyridyl)oxyacetic acid or a salt thereof, N-phosphonomethylglycine or a salt thereof, ethylcarbamoylphosphoric acid or a salt thereof, 2-(1-allyloxyaminobutylidene)-5,5-dimethyl-4-methoxycarbonyl-cyclohexane-1,3-dione, 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea,3-amino-1,2,4-triazole, choline or a salt thereof, and diethylamine or a salt thereof.
摘要:
There are provided novel substituted phenyl (thiono)carbamates capable of effectively controlling broad-leaved annual weeds and annual weeds belonging to the families Gramineae and Cyperaceae such as wild Echinochloa species, monochoria, toothcup and umbrella plant, herbicidal compositions containing these (thiono)carbamates as active ingredient and a method of controlling weeds using these (thiono)carbamates. The (thiono)carbamates are substantially nonphytotoxic to useful crop plants such as the paddy rice plant.
