Abstract:
... Pesticide residues, especially for herbicides, often damage crops, except for weeds, which results in reduced production or even death in agriculture. Brassinosteroids (BRs) can alleviate the injury from pesticide stress and enhance the growth of plants. However, the roles of low-cost BR mimetics in alleviation and protection from herbicide (nicosulfuron, NSF) stress in maize remain unclear. To in ...
