Atmospheric cold plasma alters plant traits and negatively affects the growth and development of fall armyworm in rice
Abstract Plasma is considered as the fourth state of matter, and atmospheric cold plasma (cold plasma) is a type of plasma consisting of ionized gases containing excited species of atoms, molecules, ions, and free radicals at near room temperature.

| description | Abstract Plasma is considered as the fourth state of matter, and atmospheric cold plasma (cold plasma) is a type of plasma consisting of ionized gases containing excited species of atoms, molecules, ions, and free radicals at near room temperature. Cold plasma is generated by applying high voltage to gases, causing it to ionize thus forming plasma. Although cold plasma has been found to break seed dormancy and improve germination rate, only a few studies have explored the potential of cold plasma against insect herbivory. Given that cold plasma produces reactive oxygen and nitrogen species that can activate plant signalling molecules, it is plausible that cold plasma can have differential effects against insect herbivores. To test this, we evaluated the effectiveness of cold plasma on a polyphagous lepidopteran pest, Fall armyworm (FAW) [Spodoptera frugiperda (Lepidoptera: Noctuidae)] on rice (Oryza sativa L.) using an atmospheric plasma jet reactor that generated cold plasma using ambient air as the source gas. We treated rice seeds from two commonly grown Arkansas cultivars (Jewel and Diamond) with cold plasma, followed by irrigation with Cold Plasma-Activated Water (PAW). We then independently tested FAW growth on an artificial diet partially made with PAW. Our results show that cold plasma significantly affected the feeding, growth, and development of FAW, irrespective of the rice varieties. The effects of cold plasma treatment resulted in reduced damage by FAW, lower mass gain and longer pupation period on FAW compared to the untreated control. However, the effects of cold plasma on rice growth and development were dependent on the rice varieties. Cold plasma treatment also induced detrimental effects on FAW leading to ~ 25% mortality on cold plasma-treated plants when compared to untreated controls. Collectively, these findings offer significant evidence of the potential of cold plasma as a novel component for sustainable pest management. |
