    Abstract: Herbicides containing in combination(A) compounds of the formula I ##STR1## in which R is chlorine or bromine,X is oxygen or sulfur, andR.sub.1 is hydrogen, (C.sub.1 -C.sub.4)-alkyl or a cation equivalent; and(B) compounds of the formulae ##STR2## as active components, the weight ratio of components A to B being preferably from 5:1 to 1:20. These herbicidal combinations are distinguished by a synergistic effect, especially against weed grasses in crop plants.

    Abstract translation: 除草剂组合(A)式Ⅰ的化合物其中R是氯或溴,X是氧或硫,R1是氢,(C1-C4) - 烷基或阳离子当量; 和(B)式为“IMAGE”,“IMAGE”,“IMAGE”,作为活性成分的化合物,组分A与B的重量比优选为5:1至1:20。 这些除草组合的特征在于协同效应,特别是作物作物中的杂草。

    Abstract: Heterocyclic phenyl ethers of the formula ##STR1## in which (R).sub.n is hydrogen or up to three identical or different substituents selected from halogen, CF.sub.3, NO.sub.2, CN, alkyl, alkoxy and alkylthio, and A is oxygen, sulfur or N(C.sub.1 -C.sub.4)alkyl, provided that the --OH group is not in para-position if (R).sub.n is hydrogen and A is sulfur, are useful as starting materials for the manufacture of selective herbicides.

    Abstract translation: 其中(R)n为氢或至多三个相同或不同的选自卤素,CF 3,NO 2,CN,烷基,烷氧基和烷硫基的取代基的杂环苯基醚,A为氧,硫或N( C1-C4)烷基,条件是如果(R)n为氢且A为硫,则-OH基团不在对位,可用作制备选择性除草剂的起始原料。
