Abstract:
THIS INVENTION RELATES TO A COMPOUND OF THE FORMULA
R1-O-P(=X)(-O-R2)-O-CH=C(-R2)-CO-R4
IN WHICH R1 AND R2 ARE INDENTICAL OR DIFFERENT LOWER ALKYL GROUPS, X IS AN OXYGEN OR A SULPHUR ATOM, R3 REPRESENTS A HYDROGEN ATOMS, AN ALKYL GROUP OR A HALOGEN ATOM AND R4 REPRESENTS A LOWER ALKOXY GROUP, AN ALKYL GROUP OR AN UNSUBSTITUTED OR SUBSTITUTED ARYL GROUP. THE COMPOUNDS ARE USEFUL FOR COMBATING INSECTS AND ACARIDS.
Abstract:
Phosphates and Thiophosphates containing a special morpholino or isomorpholino residue and having insecticidal, acaricidal and herbicidal properties are disclosed.
D R A W I N G WHEREIN X denotes oxygen or sulphur, the integer n is the number 0 or 1, R'' and R'''' independently of each other represent an alkyl radical with 3 to 5 carbon atoms and wherein a. if X is oxygen, R represents an alkoxyalkyl, alkylmercaptoalkyl or alkenyloxyalkyl radical with at most 7 carbon atoms, an alkenyl radical with 3 to 6 carbon atoms or an unsubstituted benzyl group or a benzyl group which is substituted by halogen, methyl and/or methoxy, or wherein b. if X is sulphur, R represents an alkenyl radical with 3 to 6 carbon atoms or an unsubstituted benzyl group or a benzyl group substituted by halogen, methyl and/or methoxy; these compounds are useful for defoliating and promoting the ripening of crop plants especially cotton.
IN WHICH R IS CHLORINE, METHYL OR CHLOROALKYL OF FROM 1 TO 3 CARBON ATOMS, N IS AN INTEGER RANGING FROM 1 TO 4, AND X IS HYDROGEN, HALOGEN, ALKENYL, ALKYNYL, ALKOXY OR -COOA WHERE A REPRESENTS ALKYL; AND THE COMPOUND HAVING THE FORMULA
Abstract:
Dithiophosphates of the formula WHEREIN R1 and R2 represent alkyl radicals of up to four carbon atoms are effective pesticidal agents, preferably for combating insects, nematodes and members of the order Acarina. The dithiophosphates may be used in pesticidal preparations.
WHEREIN R1 AND R2 REPRESENT ALKYL RADICALS OF UP TO 4 CARBON ATOMS ARE EFFECTIVE PESTICIDAL, AGENTS, PREFERABLY FOR COMBATING INSECTS, NEMATODES AND MEMBERS OF THE ORDER ACARINA. THE DITHIOPHOSPHATES MAY BE USED IN PESTICIDAL PREPARATIONS.
Abstract:
THE PRESENT INVENTION DESCRIBES NEW PHOSPHONIC ACID DITHIOL ESTERS, A METHOD FOR THEIR PREPARATION, COMPOSITIONS CONTAINING THEM AND A METHOD FOR REGULATING THE ABSCISSION OF FRUITS BY APPLYING THESE NEW ESTERS OR COMPOSITIONS CONTAINING THEM TO FRUIT TREES, OLIVE, NUT TREES, BERRY BUSHES AND GRAPES. THE NEW PHOSPHONIC ACID ESTERS CORRESPOND TO THE FORMULA
((R'',R"-PHENYL)-CH2-S)2-P(=O)-(CH2)2-CL
WHEREIN R'' IS HYDROGEN, CHLORINE, -CF3, -CN, METHYL, ETHYL, METHOXY OR ETHOXY, R" IS HYDROGEN, CHLORINE, METHYYL OR METHOXY.
Abstract:
Phosphates and Thiophosphates containing a special morpholino or isomorpholino residue and having insecticidal, acaricidal and herbicidal properties are disclosed.
Abstract:
The present invention relates to new phosphorus amidates of the general formula
IN WHICH X represents an oxygen or a sulphur atom, Y represents a bromine or an iodine atom, R1 represents a low alkyl or alkenyl radical, R2 represents a hydrogen atom or a low alkyl or alkenyl radical and R3 represents a low alkyl or alkenyl radical, or in which R2 and R3, together with the nitrogen atom to which they are bound, constitute a heterocyclic radical which may also contain other hetero atoms in addition to the said nitrogen atom as well as to pesticidal preparations which contain such phosphorus amidates as active ingredients together with a carrier.
