What about the latest dead ginger?

The phenomenon of beating ginger dead trees is a very common phenomenon for many growers, and the common phenomenon is a series of dead trees. Dead trees are seriously ill in the soil that has been planted for years. In fact, the death of ginger is mainly caused by disease. Of course, there are some environmental incentives. So in order to treat the situation of dead trees, how to treat them? next, let's take a look at the causes and understand the treatment methods.

1. Bacterial wilt

Ralstonia solanacearum is the disease of ginger blast, which is called rotten ginger directly. The performance of the disease shows that the ginger appears dark brown, then gradually turns yellowish brown, begins to rot, and after serious decay, there will be white rotten juice, with a bad smell. After the disease, the plant gradually lost green, withered, and finally lodged. If a small number of diseased plants are found, they can be dug up and burned, the soil can be disinfected, and the whole field can be sprayed with chemicals. The occurrence is a little too much, you can use 20% folazole wettable powder 800 times solution, or 20% quinolone water agent to inject roots, about once a week, more than three times the effect is good.

2. Fusarium wilt

Fusarium wilt of ginger is soil-borne bacteria, mainly because of bacteria, soil hidden bacterial infection. The disease is serious in a damp environment. After the onset of the disease, ginger pieces will turn brown and rot, unlike ginger plague, with mycelium, rotten ginger pieces have transparent juice and no bad smell. The ground will eventually die. Use 50% carbendazim 800 times solution, 70% methyl thiophanate wettable powder 800 times solution for root irrigation, root irrigation can be once every 5 days, several more times, the effect is more obvious.

3. Root rot

After the onset of the disease, the stems and leaves will have yellowish-brown disease spots, and then will rot into a water-immersed green. Then continue to infect, gradually rot, and eventually the ground will wither and die. The base of the stem will also rot inside the culm, and there are white mildew in the affected parts. Planting ginger with bacteria, soil hidden bacteria, Rain Water caused repeated infection. Use metalaxyl, quinoline copper and other drugs to treat, the same root irrigation. Once a week, about three times.

4. Other reasons

General continuous cropping, or continuous cropping too many times, leaving seeds of ginger with bacteria, as well as excessive application of nitrogen fertilizer, uneven watering, will aggravate the phenomenon of dead trees. Causing diseases that can kill trees. Excessive humidity, stagnant water will aggravate the occurrence of Fusarium wilt, high temperature and high humidity will also aggravate the occurrence of ginger blast. Some mildew will occur because of high humidity, Rain Water will repeatedly aggravate the disease.

The phenomenon of death of ginger is mainly caused by infection disease, some adverse environmental factors will aggravate the disease, resulting in serious death of trees. But generally, it can be treated reasonably.
