Substituted furazans of the formula ##STR1## in which R and R.sup.1 are identical or different and represent optionally substituted aromatic or heteroaromatic radicals,

Substituted furazan pesticides

Insecticidally and acaricidally active novel substituted furazanes of the formula ##STR1## in which R.sup.1 and R.sup.2 each independently is hydrogen, halogen, alkyl, alkoxy, alkylthio, halogenoalkyl, halogenoalkoxy, halogenoalkylthio or optionally substituted aryloxy, or

A method of combating arthropods, comprising applying to the arthropods, or to a habitat infested therewith an arthropodicidally effective amount of an antibiotic which (a) is colorless, very readily soluble in water and in pyridine but insoluble in other customary organic solvents, gives a positive reaction with ninhydrin, sodium metaperiodate/benzidine and potassium permanganate and gives a yellow coloration with iron (III) chloride, (b) has the UV and IR spectra substantially as shown in FIGS. 1 and 2, (c) on chemical degradation yields uracil, an amino-hexuronic acid and an amino-acid containing a pyridine ring, (d) on paper electrophoresis proves to be an amphoteric substance and has an isoelectric point at about pH 6 and (e) consists of the elements carbon, hydrogen, oxygen and nitrogen, or one or more active components of the antibiotic mixture, the active agent being applied alone or in admixture with a diluent or carrier. The antibiotic is known as Nikkomycin which is apparently a mixture of components of the formula ##STR1## in which R.sub.1 is ##STR2## and R.sub.2 is hydrogen, ##STR3##

Bafilomycin pesticides

Arthropodicidally and fungicidally active heavy metal salts of nikkomicin are produced by reacting nikkomicin with a water-soluble heavy metal salt in an aqueous medium.

Pesticidally active nikkomicin heavy metal salts

Pesticidally active substantially pure nikkomicin fractions obtained from Streptomyces tendae Ettlinger et al Tu 901, the fractions being selected from the group consisting of ##STR1## a mixture of nikkomicin I and J, and a mixture of nikkomicin M and N.
