The control measures of wilt disease of leeks

Symptoms of wilt disease caused by leeks: In the hot season, sudden outbreaks may occur within 2-3 hours after rain. In the middle of the leaf blade or in contact with the tip of the ground, water-like symptoms occur. In severe cases, this symptom occurs in all leaves and then it completely withers. Although the diseased roots can sprout new strains, sometimes germinating new strains will continue to develop, unless they can slowly recover after the fall. However, the yield and quality of leeks have been severely affected. Therefore, we must promptly prevent and control in order to avoid causing huge losses.

Control methods: robust leek plants are less severe, and management measures must be taken to prevent plant growth, increase plant disease resistance, and timely drainage after the rain. Immediately after hot and sweltering rain, use well water to pour it once. During the onset, use 75% chlorothalonil WP 600 times or 58% metalaxyl WP WP 500 times every 5 to 7 days to spray 1 time, and spray 2 or 3 times.
