[Control] Spray with 40% phosethyl-Al wettable powder 200-fold solution, or 50% ridomil 500-fold solution, or thiophanate-methyl 800-fold solution.

2. Sclerotinia disease

[Symptoms] The disease occurs in mid-March and damages the base of the stem. At first it shows yellow-brown or dark brown water-soaked spindle-shaped lesions. In severe cases the stem base rots, the aboveground parts lodge and wither, and mycelium and sclerotia can be seen on the soil surface.

[Control] Apply 3% sclerotinia fungicide or a mixture of 1:3 lime and plant ash onto the bed surface, or broadcast 5% chlornitrofen powder.

3. Rust disease

[Symptoms] The disease occurs in early to mid-March. In the early stage yellow-green lesions appear on the leaves, later turning yellow-brown. The lesions on the underside of the leaves or on the stems bulge and release rust-colored powder.

[Control] Spray with 60% zineb wettable powder 500-fold solution, or spray with 25% triadimefon wettable powder 1000-fold solution.

4. Yellow swallowtail butterfly

[Symptoms] From June to August there are occasionally a small number of yellow swallowtail butterfly larvae biting and eating stems and leaves. The larvae eat leaves and flower buds, causing notches or holes. When the damage is severe, only the pedicels and petioles remain.
