Systemic acquired resistance (SAR) and induced systemic resistance (ISR) are two forms of induced resistance wherein plant defenses are preconditioned by prior infection or treatment that results in resistance against subsequent challenge by a pathogen or parasite .
Can under such conditions, induce resistance may serve as a source to divert plant photosynthates to defense pathways?
Practically it is possible to induce plant resistance against diseases and pests by the application of elicitors. Many of such elicitors are on the market: Stifénia , Milsana, Actigard, Oryzemate, Bion Iodus 40, Elaxa. These elicitors induce a plant resistance against either fungi, bacteria or viruses. In addition to this induced resistance by these products, in the event of an infection by a pathogen the resistance can be further induced by the presence of specific molecules originated from the pathogen itself or from the saliva of the insects.
Hi,
It could work. However, the practical application would be tricky becase resistance would always be at the expense of growth and if we are talking crops, the yield from such plants won't be very high.
