Compounds of formula (I): ##STR1## wherein: A is 1,2,4-triazol-1-yl or imidazol-1-yl; n is 0, 1, 2 or 3; X is halogen, phenyl, alkyl, haloalkyl, alkoxy, or haloalkoxy, or (X).sub.n is alkylenedioxy; R.sup.1 is alkyl or phenyl; and R.sup.2 and R.sup.3 are each alkyl; and salts thereof have valuable anti-fungal activity. Certain intermediates in the preparation of these compounds are also disclosed.

Fungicidal silicon-containing compounds and their agrochemical and

Compounds having the formula (I) ##STR1## wherein: R.sup.1 is methyl, ethyl or isopropyl; R.sup.2 is alkyl, aralkyl, cycloalkyl, cycloalkylmethyl, aryl, heterocyclic, or heterocyclic-substituted thio; R.sup.3 is hydrogen, methyl or ethyl; or R.sup.2 together with R.sup.3 is --(CH.sub.2).sub.n --, wherein n is 3,4 or 5; and A is aromatic heterocyclic; and salts thereof, are valuable agricultural and horticultural anthelmintic, acaricidal and insecticidal agents.

13-(substituted thio)acetoxymilbemycin derivatives, their preparation

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.

Oxetane derivatives and their use as anti-fungal or fungicidal agents

1-(hydrocarbylcarbamoyl)-3-(carboxy or hydrocarbyloxycarbonyl)-isoureas and isothioureas and the lactams of the 3-carboxy compounds are useful, in association with a gibberellin (which may be naturally present in a plant), as plant growth regulators.

Use of isourea derivatives and triazine derivatives in combination with

1-(Hydrocarbylcarbamoyl)-3-(carboxy or hydrocarbyloxycarbonyl)-isoureas and isothioureas and the lactams of the 3-carboxy compounds are useful, in association with a gibberellin (which may be naturally present in a plant), as plant growth regulators.

4-Benzoyl-5-hydroxypyrazole derivatives are prepared by treating 5-benzoyloxypyrazole derivatives with more than 1 equivalent mole of alkaline substance or more than 1 mole of aluminum chloride per mole of the 5-benzoyloxypyrazole derivatives. The desired pyrazole derivatives are useful as a herbicide.
