Combinations of the known compound pyrimidifen with phosphorus-containing pesticides have a synergistic pesticidal effect, especially against mites.

Pesticidal combinations

13-Substituted milbemycin derivatives having the formula (I): ##STR1## wherein: R.sup.1 is methyl, ethyl, isopropyl or sec-butyl;

13-substituted milbemycin derivatives, their preparation and their use

A novel hydrazine derivative and a pesticidal composition containing the hydrazine derivative as the effecting ingredient. The hydrazine derivative show high pesticidal activity against harmful pests which are resistant to known pesticides such as organophosphorus pesticides, pyrethroids, etc., especially against Lepidoptera harmful pests such as Plutella xylostella, Spodoptera litura, Cnaphalocrocis medinalis, Adoxophyes orana, etc., and is effective for controlling harmful pests in paddy field, upland field, orchard, forest or places to be kept environmentally hygienic.
