BALLYA Potato Virus Y Test is manufactured by BALLYA, it’s rapid test for detection the content of Potato Virus Y in all kinds of tobaccos.
Lateral flow assay test base on the gold immunochromatography assay technology.
Potato virus Y(PVY) has a wide host range and can infect a variety of solanaceae plants, causing severe mosaic or necrotic spots and streaks on potatoes.
The virus particles are linear, with a size of 11 nm × 680~900 nm, a passivation temperature of 52~62 ℃, a dilution limit of 100~1000 times, and a survival period in vitro of 2~3 days.
The virus mainly overwinters in the poisonous potato block, which is the main initial source of disease after sowing. In the field, PVY, PVS, and PLRV can transmit poison through friction between aphids and sap.
High temperature and drought, extensive field management, numerous aphids, and serious diseases. The high temperature above 25 °C reduces the host's resistance to the virus, is conducive to the reproduction, migration and disease transmission of the virus vector aphids, which makes the disease spread rapidly and aggravates its damage.
In addition, variety resistance and cultivation measures greatly affect the degree of disease.
Because of the different strains of the virus, they show different symptoms. There are mainly veined mosaic, veined and chlorotic spot types.
Vein band type: In the upper part of
tobacco plant, the leaves are yellow-green mosaic, light color between veins, dark green on both sides of the veins, forming obvious vein bands, curling or burning spots appear in severe cases, the leaves are not mature, the color is uneven, and the quality Decline, the tobacco plant dwarf
Vein type: the lower leaves are onset, the leaves are yellowish-brown, the main lateral veins are gray-black or reddish-brown necrosis from the leaf base, the petiole is brittle, the vascular bundles can be seen brown when they are taken off, and reddish brown or black necrotic stripes appear on the stem. The chlorotic spot type is similar to the vein band type at the initial stage, but the upper leaves show chlorotic spots, and the lower middle and lower leaves produce brown or white small necrotic spots, which are irregular. In severe cases, the whole leaf spots are dense, forming perforations or shedding.
Potato virus Y disease: clear veins appear in the early stage of the tobacco plant, and soon a mosaic-shaped mottle is formed. Then the color between the veins of the lobules fades, and the tissues on both sides of the veins are dark green bands. Diseased plants infected by necrotic strains have brown to black veins.
(1) Establish a non-toxic seed potato breeding base, and use shoot tip tissue culture to ensure the cultivation of non-toxic seed potato.
(2) Select good varieties that are resistant to disease.
(3) Strengthen cultivation and disease prevention, apply adequate organic base fertilizer, and increase phosphate and potash fertilizers. Fine land preparation, high ridge or high ridge cultivation. During the growth period, weed and cultivated soil in a timely manner, watered in time to prevent flooding.
(4) Thoroughly control aphids before emergence. If necessary, carry out chemical control in the early stage of the disease.
(5) Eliminate
field weeds in time to reduce the source of overwintering bacteria. Pay attention to the layout of tobacco fields and potato and solanaceous vegetable fields.
It is best to plant high-stalk crops such as sunflower, corn, and sorghum in the middle to prevent aphids from migrating and reduce the chance of virus transmission.
