How to prevent and control pests and diseases during soybean cultivation?
I) Control of cyst nematode. 1. Strengthen quarantine and protect disease-free areas: it is forbidden to transfer soybean seeds from diseased areas. 2. Agricultural control: implement crop rotation of soybean with gramineous crops or non-host plants such as cotton; where conditions permit, paddy-upland rotation is best, and this is currently the most important

What to Do About Soybean Cyst Nematode (Dahuolong Yangzi)? A Detailed Guide to Prevention and Control
Soybean cyst nematode disease, also known as Verticillium wilt, yellow dwarf disease, and root nematode disease, is called "dahuolong yangzi" (fire dragon seedling) by farmers. According to reports, more than 22.5 million mu of soybeans in 14 provinces, municipalities, and autonomous regions in China have been infected with this disease. Soybean cyst nematode disease damages the soybean root system, causing poor growth and development of the aboveground parts of the plant, shortened and dwarfed internodes, yellowing leaves, reduced pod set, and lower yield, with general yield reductions of 10%-30%. Severely affected fields may suffer almost total crop loss. After soybeans are parasitized by nematodes, the main root and lateral roots develop poorly, and fibrous roots increase,

Identification and Control Methods of Soybean Cyst Nematode Disease
Soybean cyst nematode disease, also called "huolongyangzi" disease, is caused by nematodes parasitizing the roots of soybean. Diseased plants have poorly developed root systems, with a marked reduction in lateral roots, slow growth, stunted plants, yellowing stems and leaves, small pods with shriveled seeds, or no seed set, and even death of the entire plant. When diseased plants are pulled up and examined, many needle...
