Rice seedling-stage diseases require careful prevention and control, especially during periods of abnormal temperatures
Seedling-stage diseases are the general term for various physiological and infectious diseases during rice seedling raising, also called seedling rot. Physiological seedling rot refers to symptoms such as seed rot, bud rot, black root, greens wilt and yellow wilt death of seedlings caused by adverse environmental conditions; infectious seedling rot refers to seedling death symptoms caused by the harm of cottony leak and damping-off. During the seedling-raising period in northern rice regions, low temperatures and cold wave weather strikes are common, and the annual incidence rate of seedling rot disease is 10%~23%. Symptom characteristics 1. Physiological seedling rot: 1. Seed rot, refers to seeds rotting before germinating

How to Control Abnormal Growth in Garlic? A Detailed Guide to Practical Techniques
Abnormal growth in garlic mainly includes two types: secondary growth of garlic and onion-type garlic. Secondary growth, also known as the regrowth of degenerate leaves in garlic and commonly called "horsetail garlic," refers to the phenomenon where, at the same time the garlic scape emerges, a ring of small garlic leaves grows around the scape.

A Preliminary Study on the Prevention Methods of Two Abnormal Garlic Conditions in Cangshan Garlic
Cangshan garlic is renowned worldwide for its large bulbs, thin skins, pure white and neatly arranged cloves, and its pungent, rich flavor, with excellent qualities such as aroma, pungency, and stickiness. In recent years, due to improper planting and management methods, two abnormal garlic conditions have appeared in Cangshan garlic production. One is that the garlic simultaneously produces small garlic leaves (commonly known as "little braids") when bolting, causing difficulties during the harvest of garlic scapes and affecting the yield and quality of garlic scapes. This condition accounts for 5%-10% of the total garlic. The causes are mainly two: one is excessive nitrogen fertilizer, and the other is the effect of low temperature.

To facilitate management according to seedling condition and targeted treatment, they are described separately below. Causes of yellowing of leaves in yellow-leaf seedlings. First, soil drought. This situation mostly occurs in wheat fields with insufficient subsoil moisture or where moisture escapes through airy soil. Its characteristics are: slow tiller emergence, grayish-green leaf color, short and small central leaves, slow or stagnant growth (which farmers call "shriveled-heart seedlings"), gradual yellowing and withering of the middle and lower leaves, and few and fine roots. Key management points
