    摘要: The invention relates to a method for combating pests in genetically modified cotton plants. The plants contain a gene derived from Bacillus thuringiensis. This gene codes for and expresses a protein with an insecticidal effect. The inventive method is characterised in that an insecticidally effective quantity of one or more specified compounds is applied to the plants, to their seeds or reproductive material and/or to their growing area. The inventive method enables a reduced quantity of pesticides to be used, said pesticides working synergistically with the transgenetic plants, and increases and diversifies the efficiency of the transgenetic plants. As a result, the invention presents both economic and ecological advantages.

    摘要: There is described a process for the preparation of compounds of formula I
    in which

    R is hydrogen, optionally substituted alkyl, optionally substituted alkenyl optionally substituted cycloalkyl, optionally substituted phenyl or optionally substituted heterocyclyl, and
    R 1 and R 2 are hydrogen, an organic radical or together with the ring to which they are attached, form an optionally substituted ring, which may contain one or more hetero atoms,
    which comprises reacting a compound of formula II
    with a compound of formula III
    in which the ring Q is an optionally substituted heteroaromatic ring, which optionally comprises one or more further hetero atoms and to which is optionally fused an optionally substituted ring.
