What to Do About Manganese Deficiency in Cotton? Symptom Identification and Remedies

Growing Techniques 0 views
Young leaves first develop stripes of dark green alternating with light green between the veins, and this is more pronounced in the middle of the leaf than at the tip. The leaf tip initially turns light green, and small patches of dead spots appear within the white stripes, which later join into strips of dried tissue and cause the leaf to split lengthwise. Symptoms tend to occur on the upper part of the plant and on young tender leaves from the early squaring stage to flowering. Triggering conditions: low available manganese in plots with pH 7, high sand content and low organic matter content, and excessive rain makes it prone to leaching. Fertilization method: basal application of Liugao Base Fertilizer King is best, or choose 0.2%

Fertilization method: basal application of Liugao Base Fertilizer King is best, or choose 0.2% manganese sulfate, or 0.5-1 packet of Blue Jingdian, or 600-fold potassium permanganate, etc., and spray once each at the seedling stage, early flowering stage and boll stage.
