Abstract: A dispensing jug for bagged liquids such as milk has a removable, apertured cover, that retains the plastic bag within the jug, and prevents loss of pouring control due to bag slippage. Applying the rearwardly tapered cover pressurizes the unopened bag and pushes the front corner of the bag through the upward or forward facing aperture of the cover, where it may be pierced or severed. Some covers fit outside the lip of the jug; others fit within the lip of the jug; side windows reveal the contents of the bag within the jug, and may be conformed to spell out MILK, JUICE, etc; and one cover incorporates a flow control valve and a bag-piercing blade.

Abstract: Branched aminoalkanephosphonic acids, i.e. compounds containing at least one alkyl substituent in the .alpha.position to the phosphonic acid group are used for controlling phytopathogenic fungi by applying an effective amount of the compound to seed or foliage.

Abstract: Novel guanidated aminophosphonic acid compounds their use as biocides and their intermediates. The compounds are guanidated N-(aminoalkyl) aminoalkanephosphonic acid derivatives and are characterized in that they comprise both a phosphonic acid type group and at least one guanidino group and also in that they are based on alkylene amines. The compounds have the general formula: ##STR1## wherein Z and Z' are hydrogen, a lower alkyl group or an alkali metal, Y is hydrogen or an amidine group, m is 1-3, n is 4-16 and p is 1-3. The compounds can be prepared by reacting a halogenoalkanephosphonic acid compound with an alkylene di- or polyamine followed by guanidation of the so obtained product. The compounds are particularly useful as fungicides and especially as fungicides for industrial purposes.
