Compounds of formula (I) or (II): or salts therefor are used as phytopathogenic fungicides wherein the various radicals and substitutents are as defined in the description. Pesticidal compositions contain these compounds together with an agriculturally acceptable diluent or carrier. The compounds and compositions are applied in methods for combating pests.

A device for illuminating single or multiple page reading material in dimly lit locations, includes two hinged-together cover panels each having a holder for the reading material. The panels completely enclose the reading material in a closed condition and permit reading of the material in an open condition. An additional panel is hinged to one of the cover panels and a wireless or rechargeable lighting module with a programmable microprocessor is retained to the additional panel for moveably directing light onto the reading material. One panel may be used with a flexible strap connected to the panel and retaining the lighting module. A lanyard may be used to connect the panel to the lighting module. The panel may have a cavity and a reel on which the lanyard is wound and connected to the lighting module. The panel may have a channel for a flexible strap retaining the lighting module.

Compounds of the formula ##STR1## where one of Z and Y is CO and the other is C--W--R.sup.2 and the dotted line indicates a double bond is present where necessary to meet valency requirements, W is O, S(O).sub.n, N(R.sup.3), N(R.sup.3)(R.sup.4), N(R.sup.3)O or ON(R.sup.3); R.sup.1 is hydrogen, or an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, phenyl or heterocyclyl group; R.sup.2, R.sup.3 and R.sup.4, which may be the same or different, are as defined above for R.sup.1, or are acyl, or R.sup.2 and R.sup.3 or R.sup.2 and R.sup.4 or R.sup.3 and R.sup.4 together with the nitrogen or oxygen to which they are attached form an optionally substituted ring which may contain other hetero atoms; each X, which may be the same as or different from any other X, is halogen, CN, NO.sub.2, SF.sub.5, B(OH).sub.2, triakylsilyl or a group E, OE or S(O).sub.n E where E is a group as defined hereinbefore for R.sup.2 or is optionally substituted amino; or two adjacent groups X together with the atoms to which they are attached form an optionally substituted carbocyclic or heterocyclic ring; n is 0, 1 or 2; and p is 0 to 4 have fungicidal activity. Many of the compounds are novel.
