Resistance Activators Utilize a plant s natural resistance responses against abiotic stresses against insects against s Stimulating resistance response Two main forms: Systemic acquired resistance (SAR, induction) Induced systemic resistance (ISR, priming) Biological inducer or Chemical inducer Internal (systemic) messengers 32 Increased resistance 33 SAR ISR Resistance Activators Phosphites = SAR = ISR Aliette, Appear, SwardPhite, Magallan, Alude... Benzothiadiazole/Acibenzolar Actigard Dac Action (Daconil + Actigard) Chelated metals?
