What disease does cucumber leaf stem oozing pus indicate?

In home-grown cucumbers, this situation is very likely gummy stem blight (Didymella bryoniae). The disease initially produces oval or spindle-shaped white lesions on the stems and vines, exuding an amber-colored resinous gummy liquid. In the later stage, the diseased stems shrink and dry, splitting longitudinally in a frayed, hemp-like manner, sometimes with many small black spots appearing. When the disease is severe, the stem nodes turn black, rot, and break.

The specific control method is: in the early stage of the disease, spray 50% Flint suspension concentrate at 3000 times dilution, or 60% Baitai water-dispersible granules at 2000 times dilution, or 25% Kairun emulsifiable concentrate at 3000 times dilution, or 50% Sporgon wettable powder at 500 times dilution, or 10% difenoconazole dispersible granules at 2000 times dilution, etc., each mixed with Tianda 2116 at 600 times dilution + Tianda organosilicon at 2000 times dilution for spraying, once every 7-10 days, spraying continuously 2-3 times. On rainy days, 30% chlorothalonil smoke agent can be used at 250 grams per mu for fumigation, spraying once every 7-10 days, with continuous control 2-3 times.
