Solution Overview

Problem

Conventional methods for controlling soft rot in plants, such as those caused by Erwinia carotovora, are ineffective due to high costs, phytotoxicity issues, and insufficient disease control, particularly with antibiotics and copper-based bactericides, which also lead to metal contamination and resistance concerns.

Innovation Solution

The use of 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-alpha,alpha,alpha-trifluoro-2,6-dinitro-p-toluidine as a control agent applied to plant cultivation soil, which effectively inhibits soft rot without direct bactericidal activity on Erwinia carotovora, and can be formulated into various agricultural chemical preparations.
