What causes dry tips and yellow leaves in ginger? All the prevention and control measures are here

During the cultivation of ginger, many farmers often notice the phenomenon of dry tips and yellow leaves in ginger during management, which often leads to poor growth, weak vigor, and ultimately affects yield. So what causes dry tips and yellow leaves in ginger? How should they be prevented and controlled? Let's take a look together.

I. Causes of dry tips and yellow leaves

1. Ginger is a shallow-rooted crop that likes moisture and fears both waterlogging and drought. When it encounters prolonged high temperature and drought or continuous rainy days during the growth period, its normal growth and development will be affected, causing leaf tips to dry and leaves to turn yellow.

2. When applying base fertilizer, if incompletely decomposed farmyard manure is used, under high temperature conditions the manure accelerates fermentation in the soil, and the fermentation process releases a large amount of heat and ammonia, which can easily burn roots and cause gas damage, also leading to dry tips and yellowing in ginger.

3. When ginger develops nutrient deficiency symptoms, dry tips and yellow leaves can also appear. For example, when iron is deficient, the leaves turn white, ginger grows slowly, the plant type becomes stunted, the leaves are small, and the leaves yellow and curl.

4. Ginger is a shade-tolerant plant. When light is too strong and temperature is too high, the water consumed by transpiration far exceeds the amount absorbed by the root system, so it is very easy to cause plant dehydration and wilting, yellow leaves, and dry tips.

5. When pesticides are used improperly, especially when herbicides are used improperly and cause phytotoxicity, it can also lead to varying degrees of phytotoxicity in ginger, such as slow growth of ginger seedlings, yellowing leaves, and weak vigor.

6. Diseases such as Fusarium wilt, ginger blast, root rot, anthracnose, leaf spot, and leaf blight cause yellow leaves, with different symptoms; some are problems in the underground parts, and some are problems in the aboveground parts.

II. Prevention and control measures

First, organic fertilizer and farmyard manure used as base fertilizer and topdressing must be fully decomposed, and an appropriate amount of microbial bacterial fertilizer can also be added to the base fertilizer. Nutrient deficiency symptoms are related to the plant itself being deficient in nutrients and to excessive use of nitrogen fertilizer causing the root system to resist other elements. The trace elements needed by the plant can be supplemented by foliar spraying. For dry tips and yellow leaves caused by high temperature, shade nets can be used for shading in the early growth stage to reduce leaf transpiration, and after seedlings emerge, the film should be broken in time to prevent high temperature from scorching ginger leaves. When phytotoxicity occurs, promptly spray with 50g vinegar + 50g urea + potassium dihydrogen phosphate + brassinolide mixed with 30 jin of water, and at the same time apply microbial agent Diliwang as a root drench. For pests and diseases, comprehensive control should be adopted, with the right remedy for the condition, to keep the disease under control as much as possible and prevent further spread.
