Which month is best for planting ginger?

Ginger is a common condiment and medicinal ingredient with a wide range of characteristics and uses. When used in daily cooking, it can remove fishy smells, enhance the flavor and improve the taste of food. Let’s learn together which month is the most suitable for planting ginger?

Which month is best for planting ginger?

Ginger generally prefers warm climatic conditions and grows more luxuriantly in a humid environment. It does not require much light, so avoid direct exposure to strong sunlight. It also has a low tolerance for water and should not be planted in soil that is prone to waterlogging. The ideal soil is well-drained, fertile, loose, sandy soil. In our country, the south and Shandong region are the main ginger growing areas.

Ginger is usually planted in spring, around March to April each year, which is around the Qingming Festival. For northern regions, due to the colder climate, the planting time will be delayed accordingly, and sowing is usually carried out between April and May. This time arrangement is conducive to the smooth growth of ginger under suitable temperature and humidity conditions, thus bringing abundant output.

Control of common diseases and pests of ginger

1. Disease prevention and control

1. Ginger Anthracnose

Symptoms: Mainly affects leaves. Initially, small brown water-soaked spots appear on the leaf tips or edges, which then expand into round or irregular brown spots. In severe cases, the leaves dry up.

Prevention and treatment methods :

Rotate with non-ginger vegetables for more than 3 years.

Apply sufficient fully decomposed organic fertilizer and plant at appropriate density.

Cultivate on high ridges and strengthen fertilizer and water management.

After the rain, remove the accumulated water in time, and remove the diseased leaves in time and take them out of the field.

After harvest, remove diseased and damaged parts and burn them in batches.

2. Stem base rot

Symptoms: The suitable temperature for the disease is 20℃-25℃, and the disease is prone to occur in plots with poor ventilation and light.

Prevention and treatment methods:

Choose ginger seeds that are free of pests, diseases and mildew.

For soil disinfection, use agents such as thiophanate-methyl and carbendazim.

Apply lime for disinfection and to prevent soil-borne diseases.

2. Pest Control

1. Heartworms (ginger borer, corn borer)

Symptoms: When the seedlings are infected, the upper leaves turn yellow and wither, and the stems break.

Prevention and treatment methods:

Planting trap crops such as corn, sorghum, etc.

Biological control, such as releasing trichogrammatid wasps.

In field management, remove old and rotten leaves in time and reduce humidity.

For chemical control, use avermectin emulsifiable concentrate or other agents for root irrigation or spraying.

Manual capture: find the insect mouth in the morning, peel open the stems to catch the larvae.

Physical control, use vibration-frequency insecticidal lamps to lure and kill adult insects.

2. Ginger Beet Armyworm

Symptoms: The larvae feed on the leaves, and in severe cases the entire leaf is eaten up.

Prevention and treatment methods:

Carry out chemical control in a timely manner by spraying cypermethrin emulsifiable concentrate, imidacloprid and other pesticides.

It is recommended to treat the disease early and in its small stages, and spray pesticides for prevention and control at the appropriate time.

3. Comprehensive prevention and control measures

Treatment before sowing: Soak ginger seeds in hydrated mycobacterium soluble powder or agricultural streptomycin sulfate soluble powder.

Prevention during the growing season: Take timely measures to prevent and control underground pests when they are discovered.

Prevention and control in the early stage of the disease: Use a variety of fungicides for prevention and control, such as sinomenine, quinazole zinc suspension, etc.

Chemical control: Choose appropriate pesticides for control according to the specific situation of the disease and pest.

The above is an introduction to the sowing time and key points of disease and pest control for ginger. Ginger is mostly grown in the northern region of China. Now is around the Qingming Festival, which is the best time to sow ginger.
