Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plant source pesticide and chemical pesticide combination, in particular to a potato golden nematode repellent containing plant extract and microbial metabolite. BACKGROUND

[0002] Plant parasitic nematodes are numerous, and nematodes are small, worm-like multicellular animals that are adapted to living in water. The number of nematode species is estimated to be 500,000. Nematodes are an important part of soil animals, and they move on water films attached to soil particles. Most plant parasitic nematodes feed on plant roots, and some are endoparasites that live and feed in the tissues of tubers, tubers, buds, seeds, etc. Others are ectoparasites that feed outside plant tissues. A single endoparasitic nematode can kill a plant or reduce its productivity.

[0003] Potato golden nematode (Globodera rostochiensis) Globodera rostochiensis Skarbilovich), was first identified in Luodian County, Zhaotong City, and Zhe County, Qujing City, by five scientific research institutions including the Institute of Plant Protection, Chinese Academy of Agricultural Sciences, in June and July 2019. It was determined as a domestic quarantine harmful organism on November 4, 2020. Potato golden nematode has great harm and can cause potato yield reduction of 20%-50%, or even complete loss. Since potato golden nematode is a newly occurring domestic quarantine object, there is no practical control method in China. According to the monitoring investigation, golden nematode damage has been found in 9 counties of the city, with 5200 mu reported, and the suspected area has reached more than 30,000 mu. Comprehensive prevention and control technology research is urgently needed to ensure the healthy development of the potato industry, especially the seed potato industry.
