Disclosed are anti-avian pathogenic E. coli (APEC) agents as well as methods of using thereof.

An object of the present invention is to provide a method which does not have a problem with safety and enables controlling various pests even at a low dosage, and a pest control agent composition and a pest control agent set which are suitable to be used for the method. In the pest control method of the present invention, at least one compound selected from a compound of formula (I) (wherein, in formula (I), R.sup.1 represents a substituted or unsubstituted C1-6 alkylthio group, a substituted or unsubstituted C1-6 alkylsulfinyl group, or the like, R.sup.2 represents a hydrogen atom or a substituted or unsubstituted C1-6 alkyl group, R represents a C1-6 haloalkyl group or a C2-6 haloalkenyl group, X represents a substituted or unsubstituted C1-6 alkyl group, a substituted or unsubstituted C2-6 alkenyl group, or the like, n represents any integer of 0 to 4, and Xs are the same or different when n is 2 or more) and a salt thereof is applied with an insecticidal or acaricidal active component to an object.

This disclosure describes a biological system of plant growth promotion, pest resistance and disease resistance by application of strains of T. viride, Trichoderma harzianum K2, Bacillus amyloliquifaciens AS2, Bacillus amyloliquifaciens AS3, or a combination thereof. These strains can be used in conventional or organic agriculture for the promotion nematode resistance when applied topically as a foliar spray or as a seed coating. The highly active strains also are expected to increase plant productivity and improve quality of fruits, vegetables, flowers or other plant products.
