Abstract: The paper aims to solve the problem of fungicides use in Lonicera japonica planting. Two broadspectrum fungicides, tebuconazole and difenoconazole, were used on L. japonica for root irrigation treatment in this study. Recommended dose, double recommended dose of fungicides for twice and triple times treatment were adopted. The final fungicide residues were analyzed. In the treatments of the first crop flowers,difenoconazole was not detectable, while for the second crop of flowers, tebuconazole residues was 0.14- 0.22 mg/kg which had a risk of exceeding standard. It is recommended to use 10% of difenoconazole WG of 4000 times dilution for the root treatment of L. japonica for 2-3 times with 15 days of safety interval.
