Lanthanum-based nanomaterials suppress bacterial wilt in tomato: importance of particle morphology and dissolution profiles

Abstract

Loss of crop yield to pathogen damage seriously threatens efforts to achieve global food security. In the present work, lanthanum (La) based nanomaterials (NMs) with different morphologies and compositions, including...

Chitosan nanocarriers loaded with salicylic acid for controlling fall armyworm (Spodoptera frugiperda) and alleviating oxidative stress in maize plants

“…For instance, Wang et al found that the critical component of the biosynthetic pathway of SA (e.g., cinnamic acid and p-coumaric acid) was significantly increased by spraying 100 mg L −1 lanthanum-based nanomaterials. 47 Moreover, nanochitosan carriers can protect SA from the interference of external environments, and thus in turn increased the SA accumulation in plant leaves. 13 In addition, we also found that the SCN100 treatment remarkably increased the maize leaf JA content by 541.9% and 19.1% in the presence and absence of S. frugiperda, respectively (Fig.…”
