Lily Cucumber mosaic virus disease
[Symptoms] are generally latent infestations. If it is co-infected with lily disease-free virus, it will produce chlorotic necrotic lesions. [Pathogen] Cucumber mosaic Cucumovirus (CMV). The virus is an RNA virus belonging to the genus Cucumber mosaic virus. The virus particles are spherical and have a diameter of 30 nm. The gene components consisted of three components, RNA1, RNA2, and RNA3, coated in three virions, respectively, with genome sizes of 3357, 3050, and 2218 nt, respectively. Sedimentation coefficient 98S. The A260/280 ratio is 1.65. RNA accounts for 18% of the body weight. Host cells are generally free of inclusion bodies. The lethal temperature in tobacco sap was 70°C; the dilution end was 10-4; the in vitro survival time at 20°C was 3-6 d. There are several strains of CMV-Y, CMV-S and CMV-Q. There are some differences in the host response. [Implications of the disease] juice and worms can pass the virus. Peach pods and beetroot can also be transmitted. The virus can also be passed through the bulb to the next year. [Control] 1. Control locusts, commonly used insecticides are: 50% Malathion EC 1000 times, 40% Dimethoate 1000 ～ 1500 times, Multiple Fruit EC (40% dichlorvos, omethoate 10%) 2000-3000 times Liquid and so on. 2. Remove the diseased plant. 3. Use healthy bulbs as breeding bulbs. Disclaimer: Some articles in this website have been transferred from the Internet.

Geogrid
The Geogrid including Polyester Geogrid, Fiberglass Geogrid, Steel Plastic Composite Geogrid and Plastic Geogrid.
The geogrid is a major geosynthetic material. Compared to other geosynthetic materials, it has unique performance and efficacy. Commonly used for reinforcement of soil structure or reinforcement of composite materials.
The uses of geogrid: It is suitable for embankment and embankment reinforcement slope protection tunnel wall reinforcement large airport parking lot wharf cargo yard and other permanent bearing foundation reinforcement.
The feature of geogrid:
The high strength creep can adapt to all kinds of environment soil, and can satisfy the use of high grade highway retaining wall.
It can effectively improve the locking and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
More suitable for deep-sea operations, embankment reinforcement, fundamentally solve the other materials do stone cage due to long-term erosion by the sea caused by low strength, poor corrosion resistance, short service life and other technical problems.
It can effectively avoid the construction damage caused by the crushing and destruction of machinery and tools in the construction process.
