A method of producing novel macrolides of the formula ##STR1## wherein R means ##STR2## in which n stands for an integer of 0-2 and m denotes an integer of 0 or 1, and R' denotes a methyl or ethyl group using Streptomyces hygroscopicus is described.

The production of KSB-1939 macrolides using STR eptomyces hygroscopicus

Described are KSB-1939 compounds represented by the following general formula (I): ##STR1## wherein R means ##STR2## in which n stands for an integer of 0-2 and m denotes an integer of 0 or 1, and R' denotes a methyl or ethyl group. A production process of the KSB-1939 compounds and pesticidal agents comprising, as an effective ingredient, one of the KSB-1939 compounds are also described.

Antibiotic KSB-1939 compounds as well as pesticidal agents containing

Organic phosphoric acid ester derivatives represented by the formula (I): ##STR1## wherein R and R', which may be the same or different, each represents an alkyl group, and A represents a group of atoms necessary to complete together with the two carbon atoms to which they are attached, a 6-membered heterocyclic group containing an oxygen atom as a heteroatom; a process for preparing the same and insecticidal, miticidal or nematocidal compositions containing the same as an active ingredient are disclosed; the compositions exhibit a high ability to control insect pests, mites, nematodes and unhygienic insects harmful to agricultural and horticultural crops.
