Symptoms of lily virus disease mainly include lily mosaic disease, necrotic spot disease, ring spot disease and cluster disease. Lily mosaic leaf surface is light green, dark green and mottled, severe leaf bifurcation twisted, flower deformation or Bud is not open. Some varieties of seedlings can produce mosaic symptoms; Lily necrotic spot disease is latent infection, and some produce chlorotic mottle, and some appear necrotic spots, some varieties of flowers distorted or distorted tongue; Lily ring spot disease leaves Necrotic spots were produced, the plants had no main culms, no flowers or stunting; the diseased plants in clusters of lily clusters were clustered, and the leaves were light green or light yellow, producing streaks or mottles. The diseased young leaves are recursive and distorted, and the whole plant is dwarfed.
The pathogenic lily mosaic virus was Lily mosaic virus called lily mosaic virus. The virions were linear and 650 nm long with a lethal temperature of 70°C. The Lily symtomless virus of lily necrotic spot virus is called lily latent virus and Cu-cumber mosaic virus is called cucumber mosaic virus. Lily latent virions are linear, with a size of 635-65015-18 (nm), a lethal temperature of 65-70°C, and a dilution limit of 100,000 times. Systemic mosaics are produced on cucumber seedlings. Cucumber Mosaic virus globule, diameter 30nm, lethal temperature 60-75 °C, dilution limit 10000 times, in vitro virus protection period of 3-7 days. Lily ring spot virus was Lily ring spot virus called lily ring spot virus. In the heart smoke leaves produce yellow leaf vein mosaic, lethal temperature of 60 to 65 °C, dilution limit 1000 to 10000 times, 25 °C in vitro sterilization conditions l ~ 2 days. The lily cluster virus was Lily rosettle virus.
Transmission routes and conditions Lily mosaic virus and Lily spot virus are transmitted through sap inoculation. Aphids can also be transmitted. Lily necrotic spot disease spreads to the leap year through the bulb. In addition, the friction of the juice can also be transmitted, and melons, peach aphid, etc. are poisonous mediators. Lily cluster disease is transmitted by locusts.
Control methods (1) The breeding of bulbs of healthy plants is selected. Conditional disease-free seeding areas shall be established and diseased plants shall be removed in a timely manner. Bulbs of diseased plants shall not be used for breeding. (2) In the growth period of lily, 10% imidacloprid wettable powder 1500 times liquid or 50% anti-influx ultra wettable powder 2000 times liquid is sprayed in time to control the transmission of aphids and reduce the spread of the disease. (3) In the early stage of onset, 20% of toxic nemesis WP 500 to 600 times or 0.5% of antiviral 1 of water 300 to 350 times of liquid, 5% of bactericidal WP of 500 times, 20% Virus Ning water-soluble powder 500 times, once every 7-10 days, even defense 3 times.
Ovulation Test has a history of 50 years. The primary method used rabbit or frog but the sensitivity is very low. Contemporary LH tests include direct coagulation way,coagulation inhibition way,RIA and ELISA. As the application of the monoclonal antibody technology these years, "sandwich enzyme-immunology way" is getting more and more popular. The method employs a unique combination of two specific monoclonal antibodies with two different sites on one LH molecule to determine the quantity of LH in the patient`s urine according to the intensity of the color, in the help of color effect of enzyme boosting reaction.The sensitivity can reach 5mIU/ml. In 30 to 60 minutes, the test could be finished, without using any special instrument or isotope, while increasing the specificity in the same time.
