According to the wintering base survey of pests and diseases in the agricultural pest monitoring network of Hebei Province, combined with long-term climate prediction and farmland ecological conditions, a consultation analysis of pests and diseases of vegetables and fruit trees was conducted.

Leaf disease strains rate of 5% to 30%. The rate of gray mold disease is 5-33.5%. The epidemic was widespread and the highest diseased rate was 32% (Bazhou tomato early blight). The average insect strain rate of Liriomyza sativae in the province is 5% to 30%, and the highest strain rate is 60% (Dachang). The rate of B. tabaci strains was 5–30%, the highest strain rate was 60.8% (Yongnian), and the highest single leafworm quantity was 15 (Qingxian). The number of wintering pods for C. arborea is 5, and the highest is 20. The overwintering mite number for the diamondback moth is 6 heads and the highest is 42 heads (Xianhe).
