IMPROVEMENTS IN AND RELATING TO PLANT PROTECTION

摘要

Provided is a method of treating a seed with a seed treatment composition to induce a plant resistance mechanism against one or more pests in a plant grown from said seed so as to restrict plant damage by pests, the method including applying the treatment composition to a seed, wherein the seed is a non-germinated seed, and wherein the treatment composition includes a treatment agent selected from jasmonic acid (JA) or its jasmonate salts wherein said salts are selected from the group consisting of potassium or sodium jasmonate; jasmonic acid methyl ester; jasmonic acid- L-amino acid amide-linked conjugates selected from the group consisting of the conjugate with L-isoleucine or the conjugates with L-valine, L-leucine and L-phenylalanine; 12-oxo-phytodienoic acid; coronatine; coronafacoyl-L-serine and coronafacoyl-L-threonine; methyl esters of 1-oxo-indanoylisoleucine and 1-oxo-indanoyl-leucine; coronalon; or combinations thereof, wherein the resistance mechanism is induced due to the treatment of the non-germinated seed rather than due to carry over of treatment composition from the seed onto a germinating plant.
