摘要:
Compounds of the formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are H, methyl, or ethyl, and wherein at least one of R.sup.1 and R.sup.2 is methyl or ethyl, are disclosed to control cockroaches.
摘要:
Combinations of a chitin synthesis inhibitor (e.g. hexaflumuron, flufenoxuron, lufenuron, and dimiin) with a juvenile hormone mimic (e.g. methoprene and pyriproxyfen) afford synergistic activity against termites.
摘要:
Compounds of the formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are H, methyl, or ethyl, have unexpected activity against cockroaches, ants, fleas, and termites. Compounds wherein at least one of R.sup.1 and R.sup.2 is methyl or ethyl are novel.
摘要:
Novel N-aroyl N'-phenyl ureas having halogen substituents in the 3- and 5-positions and haloalkyl, haloalkoxy or haloalkylthio in the 4-position of the N'-phenyl are more active and have a broader spectrum of effectiveness than the known benzoylurea insecticides.
摘要:
Dihalo and haloalkyl, haloalkoxy or haloalkylthio-substituted anilines and aniline derivatives, e.g. isocyanates that are useful in the preparation of acyl ureas having insecticidal activity.
摘要:
Method of protecting plants from both fungal organisms and mites in the same treatment in which there is applied to the plant an amount of one or more of selected tricyclopentyl tin and tris(cyclopentylmethyl)tin compounds, which amount is sufficient to provide both antifungal and miticidal protection but is less than a substantially harmful phytotoxic amount. Counter ions in these compounds which are suitable include hydroxy, halo, oxo, thioxo, alkyl- and aryl carboxylate, thiocyanato, diloweralkyldithiocarbamoyl and diethoxyphosphinothioylthio.
