Garlic spring rot can last until mid-June, when it is cold and humid, and it lasts until harvest. It mainly harms the base of the lower lobe. The appearance of water-softening lesions followed by enlargement in the upward and downward direction showed pale brown rot. In the late stages of growth, the heart and leaves develop, and the softening and rot spreads below the stem. It can sometimes cause the emerging bulbs to rot. After the onset of the leaves, the number of leaves decreased and the bulbs became obstructed. Leaf sheaths close to the ground cause cracks in bulbs and their quality deteriorates. At the beginning of onset or at the beginning of the spread, 47% Chlorhexidine copper WP can be used 700 times, or 78% Boron Manganese Zn wettable powder 500 times, 50% Chlorobromoisocyanurate soluble powder 1200 times, 53.8 % of copper hydroxide dry suspension agent 1000 times and other spray control, 7 days, 1 and even 2 or 3 times.
