Abstract: The invention is concerned with new herbicidally active 4-phenoxy-.alpha.-phenoxy-alkanecarboxylic acid derivatives, especially propionic acid esters of the type ##STR1## bearing in the first phenoxy radical a nitro group besides another substituent R.sub.1 which is preferably a halogen atom, the CF.sub.3 group is lower alkyl, alkoxy or alkoxycarbonyl group. The invention is further concerned with herbicidal compositions containing such new derivatives and with methods for the selective control of grass-like weeds in crops of dicotyledonous and monocotyledonous cultivated plants such as cereals.

Abstract: The present invention relates to 1,2,4-triazolidine compounds, to a process for producing them, to their use for controlling vegetable and animal pests in agriculture, and to compositions, which contain these 1,2,4-triazolidine compounds as active substance.The 1,2,4-triazolidine compounds correspond to formula ##STR1## wherein ARYL IS AN ARYL GROUP OTHER THAN BENZENE, ANDY is an oxygen or sulphur atom.

Abstract: The present invention is based on the observation that certain oxime-ethers show a synergistic effect when used with insecticidally and/or acaricidally active substances.

Abstract: The invention relates to a method for the cultivation of plants involving the regulation of plant growth which comprises applying an effective amount of a compound of the formula I ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3, independently of one another, represent hydrogen, chlorine, bromine, methyl, ethyl, trifluoromethyl or cyano,R.sub.4 represents methyl or ethyl andR.sub.5, r.sub.6 and R.sub.7, independently of one another, represent hydrogen, chlorine, bromine or C.sub.1 -C.sub.4 -alkyl.

Abstract: The present invention is based on the observation that certain oxime-ethers show a synergistic effect when used with insecticidally and/or acaricidally active substances.

Abstract: Formamidine compounds of the formula ##EQU1## or WHEREIN R.sub.1 represents a substituted or unsubstituted phenyl radical, R.sub.2 represents hydroogen, alkyl, alkenyl or alkinyl and R.sub.3 represents acyl their manufacture and their use in pest control.

Abstract: Phenylformamidines of the formula ##SPC1##Wherein R.sub.1 represents hydrogen, alkyl, alkenyl or alkynyl, R.sub.2 represents .alpha.-naphthyl, ##SPC2##Or substituted phenyl,Wherein the phenyl group is not substituted simultaneously in the 2-position by a methyl group and in the 4-position by a chlorine atom, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 represent one or more radicals which are the same or different, such as hydrogen or halogen atoms or alkyl, alkoxy, alkylthio, alkenyloxy, alkynyloxy, alkoxycarbonyl, CF.sub.3, cyano or nitro groups, their process for the manufacture and their use in pest control.

Abstract: The present invention provides compounds of the formula ##SPC1##In which X represents chlorine and R.sub.1 represents unsubstituted alkenyl of 2 to 4 carbon atoms or chloro substituted alkenyl of 2 to 4 carbon atoms or in which X represents bromine and R.sub.1 represents vinyl-, chloro substituted allyl-, or methallyl-, butenyl or chloro substituted butenyl. The novel compounds are useful for combatting representatives of the order Acarina.
