The pathogen of walnut bacterial blight generally overwinters in twigs or buds, and in the following spring exudes bacterial fluid that spreads via wind and rain, mainly damaging young fruit, leaves and tender twigs. Management methods:
1. Overwintering management. After leaf fall, apply Husu Jiangjun to the trunk and branches to hinder the pathogen from multiplying on the tree body, providing insulation, disinfection and frost protection. At the same time, spray Husu Jiangjun for whole-orchard disinfection.
2. Disease control. For diseased tree bodies, promptly spray the whole orchard with chemicals plus New High-fat Film to form a protective film, enhance the efficacy of the chemicals, and prevent the pathogen from spreading and infecting via wind and rain.
3. Wound management. For some pruning cuts and wounds, promptly apply callus antiseptic film to protect the wounds and prevent pathogen invasion and rainwater contamination.
