In a logarithmic differential pore volume distribution by a mercury intrusion method, the electrode mixture layer satisfies: a ratio P1/P2 within a range of 2 or more and less than 8, and a ratio S1/S2 within a range of 3 or more and less than 10. P1 is a value of a maximum logarithmic differential pore volume in a pore diameter range of 0.1 ?m or more and 1 ?m or less. P2 is a value of a logarithmic differential pore volume of a pore diameter of 0.03 ?m. S1 is an integrated value in a pore diameter range of 0.1 ?m or more and 1 ?m or less. S2 is an integrated value in a pore diameter range of more than 0 ?m and less than 0.1 ?m.

Abstract: 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.

Abstract: 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 noticeably enhanced by applying in combination with certain known herbicides or compounds having biological activities.

Abstract: 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.

Abstract: Disclosed are compounds having the following general formula: ##STR1## wherein n is an integer of 1 or 2; R.sup.1 is an amino group when n is 2, or an amino group or a hydroxyl group when n is 1; and R.sup.2 is a hydroxyl group when n is 1, or a hydroxyl group or a group of the formula ##STR2## when n is 2; and microbiological process for producing the same. The compounds are useful as precursors for raising the production rate of SF-1293 substance. Some of the compounds are also useful as intermediates for synthesis of 2-amino-4-(hydroxy)(methyl)phosphinoylbutyric acid and the SF-1293 substance.

Abstract: 2-Amino-4-(hydroxy)phosphinoylbutyryl-L-alanyl-L-alanine.
