Compositions and methods for protecting an organism from a pathogen are disclosed.

The present disclosure provides methods for killing pests such as nematodes, oomycetes, and fungi, involving treating an object or area with an effective amount of a composition containing at least one compound of formula 1, wherein R1 is CH.sub.3, C.sub.2H.sub.5, C.sub.3H.sub.7; saturated or unsaturated, straight or branched, or halogen substituted alkyl; and wherein R2 are independently H, halogen, nitrogen, oxygen, sulfur, saturated or unsaturated, straight or branched alkyl, alkenyl, alkyl halide, aldehyde, ketone, ether, ester, amine, or amide; optionally methyl benzoate, optionally a surfactant, and optionally a carrier.

Compounds of formula (I) wherein the substituents are as defined in claim 1, and the agrochemically acceptable salts, stereoisomers, enantiomers, tautomers and N-oxides of those compounds, can be used as insecticides.

##STR00001##

A method of phytosanitary treatment, which includes the step of administering a nematicidal composition, is disclosed. The nematicidal composition includes cinnamic aldehyde and terpene alcohol as active ingredients as a nematicide in a phytosanitary treatment, particularly in crops of banana, plantain, table and wine grapes, fruit trees, citrus plants, strawberries, and soy. Main advantages of the invention include high efficacy against nematodes, great stability over time, and the very low toxicity of the composition, both for plants and humans.
