Analysis of Cereal Cyst Nematode Diseases

Cereal cyst nematode (CCN) is a worldwide disease affecting wheat, barley, rye, oats, sorghum, and other cereal crops, as well as more than 40 kinds of grass such as purple fescue, oxtail grass, fescue. The cereal cyst nematode (Heterodera avenae Wollenweber) was first found on wheat in Britain in 1908 and was reported in Oregon in 1975. This nematode has been found in Europe, Canada, Australia, Africa, and other countries and can reduce wheat production by 30%-70% in severe cases.

Lifeasible develops an advanced platform equipped with advanced instruments and professional staff to analyze cereal cyst nematode diseases with a high standard. We customize featured services according to the customers' demand.

Pathogen Analysis of Cereal Cyst Nematode Diseases

• The 2nd instar larvae of cereal cyst nematodes infect cereal, which does harm to the roots of crops, affect the growth of root tips, and result in the increase of fibrous roots, abnormal branching, and thin and tangled roots.

• Lifeasible provides identification methods, including morphological characterization, molecular biology identification, isoenzyme phenotype analysis, cytogenetics, host identification tests, etc. We also help customers study nematode hatching characteristics, such as the effects of temperature and pH on nematode hatching. In addition, studying the life cycle of nematodes is also on our list of services, involving infection algebra, time, etc.

Analysis of Pathogenesis Regularity

• Studying the regularity of the disease can guide the prevention and control of nematodes to reduce damage loss. The time of infection by the second instar larvae and the development of nematodes in cereal roots are related to regional climatic conditions, soil types, tillage methods, crop varieties, and others.
• We provide an analysis of pathogenesis regularity. The services include the investigation of occurrence generation, host range, distribution and incidence degree, the incidence of different varieties, and the influence of different tillage systems on the incidence. Specifically, we record the disease incidence by field number, disease stalk rate, and disease index.

Analysis of Yield Losses

• It is of great significance to study the damage level of cereal cyst nematode disease at different stages, measure the yield loss under different CCN population densities, and determine its economic threshold to further develop control indicators and guide the control work.

• We provide an analysis of loss from nematode damages. We help analyze wheat agronomic traits and yield losses under different CCN population densities. The outline of the method is to measure plant height, effective panicle number, grain number per spike, 1000-grain weight, and other indicators at the maturity stage.

Analysis of Pathogenic Mechanism

We provide a mechanism analysis of the harm caused by cereal cyst nematodes, mainly by robbing the host of nutrients, disrupting hormone balance, causing mechanical damage, and so on.
