A composition comprising the dihydrate of the calcium salt of 3-hydroxy-5-methylisoxazole and cupric hydroxide and a method of protecting crops by applying the composition to plants or a locus thereof.

Composition containing the dihydrate of the calcium salt of

A combination of 3-hydroxy-5-methylisoxazole with an antimicrobial agent has good agricultural fungicidal activity which lasts longer than 3-hydroxy-5-methylisoxazole alone. The dihydrate of the calcium salt of 3-hydroxy-5-methylisoxazole has advantages over the free 3-hydroxy-5-methylisoxazole, other salts and the anhydrous compound.

Agrochemical compositions and methods employing hymexazol and

Compounds of formula (I): ##STR1## [in which: R.sup.1 and R.sup.2 are hydrogen or alkyl, or together are cycloalkyl; R.sup.3 and R.sup.4 are hydrogen, alkyl or phenyl, or together are cycloalkyl; or R.sup.1 and R.sup.3 together are cycloalkyl fused to the oxetane ring; Ar is phenyl substituted by R.sup.5, R.sup.6 and R.sup.7, where R.sup.5, R.sup.6 and R.sup.7 are hydrogen, halogen, alkyl, alkoxy, halogenated alkyl or halogenated alkoxy; and R.sup.8 and R.sup.9 are hydrogen or alkyl] and salts thereof have valuable agricultural and pharmaceutical anti-fungal or fungicidal activity. They may be prepared by a variety of processes.

Pyridazinone derivatives, their preparation and their use in

6-(3- And/or 5-halophenyl)pyridazines having an N-substituted carbamoyloxy, carbamoylthio, thiocarbamoyloxy or thiocarbamoylthio group at the 3- position on they pyridazine system and 6-(3- and/or 5-halophenyl)-3-pyridazone derivatives having a substituted or unsubstituted hydrocarbyloxycarbonyl substituent at the 2-position of the pyridazine ring have good fungicidal activity, making them useful as agricultural fungicides suitable for application to seeds, plants and agricultural land, and can be prepared by reacting the corresponding 6-substituted pyridazone or pyridazinethione with the corresponding carbamoyl halide or halocarbonate.

Pyridazine derivatives and their use as agricultural fungicides
