Abstract
This invention provides an insecticidal and miticidal agent which contains as an effective ingredient an oxazoline derivative represented by the formula ##STR1## wherein, R.sup.1 represents a fluorine atom, a chlorine atom, a C.sub.1 to C.sub.3 alkyl group or a C.sub.1 to C.sub.3 alkoxy group, and R.sup.2 represents a fluorine atom or a chlorine atom. The insecticidal and miticidal agent exhibits an excellent insecticidal and miticidal activity against harmful insects and mites parasitic on useful plants.
Claims12
A composition for control of plant-parasitic insects and mites which comprises an insecticidally and miticidally effective amount of an oxazoline derivative represented by the formula ##STR14## wherein R.sup.1 represents a fluorine atom, a chlorine atom or a methyl group,
- and agrohorticulturally acceptable adjuvants.
A method for controlling an insect or mite harmful to an agrohorticultural crop which comprises applying an insecticidally or miticidally effective amount of an oxazoline derivative represented by the formula ##STR15## wherein R.sup.l represents a fluorine atom, a chlorine atom or a methyl group,
- directly to imagoes, larvae or nits of the insect or mite, or to a locus inhabited by the imagoes, larvae or nits.
A composition for control of plant-parasitic insects and mites in the form of an emulsion, flowable agent or wettable powder, which comprises 0.01 to 50% by weight of an oxazoline derivative represented by the formula ##STR16## wherein R.sup.1 represents a fluorine atom, a chlorine atom or a methyl group,
- and agrohorticulturally acceptable adjuvants.
A method for controlling an insect or mite harmful to an agrohorticultural crop which comprises applying a composition in the form of an emulsion, flowable agent or wettable powder, comprising 0.01 to 50% by weight of an oxazoline derivative represented by the formula ##STR17## wherein R.sup.1 represents a fluorine atom, a chlorine atom or a methyl group,
- and agrohorticulturally acceptable adjuvants, at a rate of 0.1 to 10 kg per hectare, directly to imagoes, larvae or nits of the insect or mite, or to a locus inhabited by the imagoes, larvae or nits.
