Fusarium wilt control: how to do cowpea Fusarium wilt? How is cowpea treated with Fusarium wilt?
Cowpea is a common dish on the market, and many people like to eat it. How to treat cowpea with wilt disease? Let's take a look.
Cowpea (commonly known as "kidney bean" in Taiwanese) grows from April to September. It is an important summer vegetable in Taiwan."Sanchiqingpi" is the most common cowpea variety, mainly grown in Kaohsiung and Pingtung. However, cowpea has been seriously affected by wilt disease in the last ten years, and a large number of cowpeas have died six or seven weeks after planting, just at flowering period. The control effect on cultivated land is limited, and there is no cure for it. It is regarded as "bean cancer" by farmers, causing many farmers to have headaches and reduce their willingness to plant.
Chu Ya-ling, an assistant researcher at the Kaohsiung Agricultural Reform Station, says that long-term cultivation of soil will accumulate fungi, and the pathogens that inhabit the soil will invade the cowpea roots, destroy the vascular bundles that carry water, and spread upward. In the early stages of the disease, the leaves will curl and wither, and in the later stages, the whole plant will die. Cowpea farmers lack effective field control methods, wilt damage is too serious, many farmers will still use drugs, but are ineffective drugs.
In 2016, Kaohsiung Agricultural Reform Station officially launched the "Wilt Resistant Grafting Seedling Technology" and transferred it to the Grape Field Seedling Farm. Zhu Yaling mentioned that the original cost of cowpea was about 0.4 yuan. After technology transfer, the price of cowpea seedling was 6 yuan, which was increased by 15 times. She worried that farmers could not accept it. However, many people asked about grafted seedlings in the past two years, and the seedling operators even exceeded the demand. The owner of the organic farm said that although good planting management, but only cowpea wilt disease can not be done, tried to use cowpea wilt resistant grafted seedlings, found that cowpea disease resistance significantly improved, no longer dead.
