Compounds of formula (1)n wherein R represents a sugar residue or an acylated derivative thereof; nR¹ represents a methyl, ethyl or isopropyl group; nY¹ is -CH₂, Y² is -CH- and X representsn [wherein R² represents a hydrogen atom or a group OR⁶ (where OR⁶ is a hydroxyl group or a substituted hydroxyl group having up to 25 carbon atoms) and R³ represents a hydrogen atom, or R² and R³ together with the carbon atom to which they are attached represent >C=0, >C=CH₂ or >C=NOR⁷ (where R⁷ represents a hydrogen atom, a C₁₋₈ alkyl group or a C₃₋₈ alkenyl group) and the group >C=NOR⁷ is in the E configuration] or -Y¹-X-Y²- represents -CH=CH-CH- or -CH₂-CH=C- ; and R⁴ represents a group OR⁶ as defined above and R⁵ represents a hydrogen atom, or R⁴ and R⁵ together with the carbon atom to which the are attached represent >C=0 or >C=NOR⁸ (where R⁸ is as defined above for R⁷), and salts thereof. The compounds may be used to control nematode, acarine, insect or other pests. |
