摘要:
Novel 2-nitro-5-phenoxyphenyloxazoles, -oxazines and -thiazoles are disclosed. These compounds have the formula ##STR1## wherein A is a C.sub.2 -C.sub.3 alkylene or C.sub.2 -C.sub.3 alkenylene radical which can be substituted by C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 haloalkyl, each of R.sub.1, R.sub.2 and R.sub.3 independently is hydrogen, halogen, trifluoromethyl, nitro or cyano, and X is oxygen, sulfur or an imino group. The novel compounds have herbicidal and plant growth-inhibiting properties. They are especially suitable for use as selective herbicides in crops of cereals.
摘要:
A device for combatting troublesome flying insects comprising a sloped target area containing a wet or dry dosage of tetrahydro-2-(nitromethylene)-2H-1,3-thiazine lethal to flies and covered with a closely fitting or flush grill; a hollow base section having a bottom and side or sides; a cavity for the containment and concealment of intoxicated flies; and a means of supporting said target area. In the case where the device contains a wet amount of said insecticide, the device further contains a means of establishing fluid contact between the target area and a fluid reservoir in the base section. Also claimed is a method for combatting flies utilizing the devices of the invention.
