Methods of controlling crop pests using aromatic amide insect repellents, methods of making aromatic amide insect repellents, and novel aromatic amide insect repellents

Abstract

Methods of protecting fruit crops from flying insect pests and of repelling flying insects using aromatic amide compounds are disclosed. The methods apply the compounds to various surfaces, such as the fruit crops, the ground or structures adjacent to the fruit crops, or an object, article, human skin or animal. The compounds have the formula RCH—C(═O)—N(Cy), where RCHis a substituted phenyl group, each R group is independently C-Calkyl, substituted C-Calkyl, (substituted) C-Caryl, C-Calkoxy, C-Caryloxy, halogen, nitro, cyano, cyanate, isocyanate, nitroso, C-Calkylthio, phenylthio, (halogen-substituted) C-Calkylsulfonyl, phenylsulfonyl, tolylsulfonyl, amino, mono- or di-C-Calkylamino, diphenylamino, di-C-Calkylamido, formyl, C-Cacyl, or C-Calkoxycarbonyl; x is an integer of 1 to 5; x+y=5; Cy is a C-C(substituted) alkadiyl, a C-C(substituted) alkenediyl, or a (substituted) diyl of the formula —(CHCH)—O—(CHCH)—, —(CHCH)—NR'—(CHCH)— or —(CHCH)—S—(CHCH)— that, along with the amide N atom, forms a non-aromatic cyclic group; and R′ is C-Calkyl, substituted C-Calkyl, (substituted) C-Caryl, or (substituted) benzyl.
